Narrator:
Today on "How it's made,"
4
00:00:26,068 --> 00:00:27,965
Cartridge blades,
5
00:00:32,241 --> 00:00:35,034
Chocolate banana loaves,
6
00:00:38,379 --> 00:00:40,103
Vending machines
7
00:00:44,241 --> 00:00:46,482
And dive computers.
8
00:00:53,793 --> 00:00:56,206
Developed in the middle
Of the 20th century,
9
00:00:56,206 --> 00:00:57,965
The cartridge blade
Is an invention
10
00:00:57,965 --> 00:01:00,275
With many cutting edges.
11
00:01:00,275 --> 00:01:04,172
The plastic cartridge
Houses up to five razor blades.
12
00:01:04,172 --> 00:01:05,862
With multiple blades,
13
00:01:05,862 --> 00:01:08,206
Fewer shaving strokes
May be necessary,
14
00:01:08,206 --> 00:01:11,000
Which results
In a faster shave.
15
00:01:14,137 --> 00:01:16,034
For the multibladed
Cartridge razor,
16
00:01:16,034 --> 00:01:18,862
Getting rid of stubble
Is no trouble.
17
00:01:18,862 --> 00:01:20,793
When the many blades
Become dull,
18
00:01:20,793 --> 00:01:22,965
The cartridge
Can simply be popped out
19
00:01:22,965 --> 00:01:25,517
And replaced
With a new one.
20
00:01:25,517 --> 00:01:28,517
Making cartridge blades starts
With coiled steel strips
21
00:01:28,517 --> 00:01:31,896
That are a few miles long.
22
00:01:31,896 --> 00:01:34,241
The strips unwind
Around guide rollers
23
00:01:34,241 --> 00:01:38,655
That orient them
For entry into punch machines.
24
00:01:38,655 --> 00:01:43,586
Revolving cylinders help feed
The steel strips to the punches.
25
00:01:43,586 --> 00:01:45,965
The punches cut holes
In the steel,
26
00:01:45,965 --> 00:01:48,965
Spacing them at
Precise intervals.
27
00:01:48,965 --> 00:01:51,241
These holes will
Allow production machinery
28
00:01:51,241 --> 00:01:52,517
To grip the steel
29
00:01:52,517 --> 00:01:56,724
And move it through
The blade-making process.
30
00:01:56,724 --> 00:01:59,482
Machinery pulls the steel
Ribbons through an oven,
31
00:01:59,482 --> 00:02:04,482
Which heats them to a searing
1,832 degrees fahrenheit.
32
00:02:04,482 --> 00:02:07,068
The steel then enters
A cooling chamber,
33
00:02:07,068 --> 00:02:09,068
Followed by another oven.
34
00:02:09,068 --> 00:02:10,758
The temperature extremes change
35
00:02:10,758 --> 00:02:12,896
The steel's molecular structure.
36
00:02:12,896 --> 00:02:16,758
It becomes harder and stronger.
37
00:02:16,758 --> 00:02:18,931
The steel rewinds
And then unwinds
38
00:02:18,931 --> 00:02:20,586
Between grinding stones
39
00:02:20,586 --> 00:02:22,793
That hone the edge
Into a very sharp
40
00:02:22,793 --> 00:02:24,689
Gothic arch profile.
41
00:02:26,965 --> 00:02:31,517
They're now ready to break the
Steel into individual blades.
42
00:02:31,517 --> 00:02:37,103
A mechanical punch snaps it.
And it breaks cleanly.
43
00:02:37,103 --> 00:02:39,827
With a skewer holding
The blades in alignment,
44
00:02:39,827 --> 00:02:44,620
A technician scrutinizes
The edges for any defects.
45
00:02:44,620 --> 00:02:46,724
After applying coatings
To prevent
46
00:02:46,724 --> 00:02:48,620
Rust and add durability,
47
00:02:48,620 --> 00:02:51,379
They bake the blades
In a special furnace.
48
00:02:51,379 --> 00:02:55,655
This binds the coatings
To the blades.
49
00:02:55,655 --> 00:02:58,689
At another station,
They transform plastic pellets
50
00:02:58,689 --> 00:03:00,862
Into the razor cartridges.
51
00:03:00,862 --> 00:03:02,793
This machine melts the pellets
52
00:03:02,793 --> 00:03:05,275
And injects the liquid
Plastic into molds
53
00:03:05,275 --> 00:03:07,379
As pressure is applied.
54
00:03:07,379 --> 00:03:08,827
The plastic solidifies
55
00:03:08,827 --> 00:03:13,172
Into the shape
Of razor cartridges.
56
00:03:13,172 --> 00:03:16,103
The cartridges bounce along
A circular feeder.
57
00:03:16,103 --> 00:03:19,137
The feeder orients them
Front-side-up
58
00:03:19,137 --> 00:03:21,758
And then funnels them
Into the next machine.
59
00:03:25,275 --> 00:03:29,586
This one resembles an octopus
With numerous tentacles.
60
00:03:29,586 --> 00:03:31,931
The tentacles are robots.
61
00:03:31,931 --> 00:03:33,827
The first one places
The cartridges
62
00:03:33,827 --> 00:03:36,068
In a fixture
On a revolving table.
63
00:03:38,172 --> 00:03:39,862
As the table turns,
64
00:03:39,862 --> 00:03:41,344
It serves up the cartridges
65
00:03:41,344 --> 00:03:44,068
To the next robots
In the assembly line.
66
00:03:47,103 --> 00:03:49,724
In quick succession,
These robots snap
67
00:03:49,724 --> 00:03:54,103
A total of five blades
Into the cartridges.
68
00:03:54,103 --> 00:03:56,172
By now, the holes used
To move the blades
69
00:03:56,172 --> 00:03:59,689
Through the assembly process
Have been trimmed off.
70
00:03:59,689 --> 00:04:02,275
And it's a perfect fit.
71
00:04:05,689 --> 00:04:08,931
They now place back casings
In front of the cartridges
72
00:04:08,931 --> 00:04:12,103
And install pieces of metal
On the parts.
73
00:04:12,103 --> 00:04:15,482
The metal pieces
Are sacrificial anodes.
74
00:04:15,482 --> 00:04:17,758
Their sole purpose
Is to be sacrificed
75
00:04:17,758 --> 00:04:21,517
To corrosive forces
To save the blades.
76
00:04:21,517 --> 00:04:24,655
After that, robots flip
The back casings
77
00:04:24,655 --> 00:04:27,137
Then transfer them
To the cartridge blades
78
00:04:27,137 --> 00:04:29,137
And click them into place.
79
00:04:32,482 --> 00:04:35,172
The cartridge blades are now
Fully assembled.
80
00:04:37,551 --> 00:04:40,172
The robotic system takes
Them into a station
81
00:04:40,172 --> 00:04:43,517
With more quality
Control cameras.
82
00:04:43,517 --> 00:04:45,206
If no problems are found,
83
00:04:45,206 --> 00:04:49,034
The blades move into
Another mechanized system.
84
00:04:49,034 --> 00:04:51,758
This one installs
A temporary plastic cover
85
00:04:51,758 --> 00:04:53,379
To protect the consumer
86
00:04:53,379 --> 00:04:56,655
And keep the blades sharp
Until it's time for a shave.
87
00:04:59,000 --> 00:05:01,931
Robotic arms pick up
The clear plastic protectors
88
00:05:01,931 --> 00:05:03,275
Two at a time
89
00:05:03,275 --> 00:05:06,275
And place them in slots
In the assembly machine.
90
00:05:09,482 --> 00:05:11,517
They then snap
The cartridge blades
91
00:05:11,517 --> 00:05:13,379
Into the plastic covers.
92
00:05:17,275 --> 00:05:19,275
With the protectors in place,
93
00:05:19,275 --> 00:05:22,137
The robots send the cartridge
Blades down a chute
94
00:05:22,137 --> 00:05:24,344
And into a bin.
95
00:05:24,344 --> 00:05:26,344
They're now ready
For retail
96
00:05:26,344 --> 00:05:29,379
And the business
Of personal grooming.
97
00:05:43,448 --> 00:05:46,413
Narrator:
Many schools today require
All food on the premises
98
00:05:46,413 --> 00:05:47,965
To be allergy-free
99
00:05:47,965 --> 00:05:49,241
Because so many children
100
00:05:49,241 --> 00:05:51,586
Have life-threatening
To peanuts,
101
00:05:51,586 --> 00:05:54,000
Tree nuts or dairy products.
102
00:05:54,000 --> 00:05:56,241
Often, these allergies
Are so severe
103
00:05:56,241 --> 00:05:58,620
That just touching
Or inhaling the allergen
104
00:05:58,620 --> 00:06:03,379
Can cause a potentially
Deadly reaction.
105
00:06:03,379 --> 00:06:06,275
These kid-sized chocolate
Chip banana loaves contain
106
00:06:06,275 --> 00:06:09,517
No peanuts, tree nuts
Or dairy products.
107
00:06:09,517 --> 00:06:11,793
Nothing else this company
Makes contains them
108
00:06:11,793 --> 00:06:14,068
Either to eliminate
Any possibility
109
00:06:14,068 --> 00:06:16,241
Of cross-contamination.
110
00:06:16,241 --> 00:06:17,827
As a further precaution,
111
00:06:17,827 --> 00:06:20,068
All the ingredients
Come from suppliers
112
00:06:20,068 --> 00:06:22,896
Whose facilities are also
Entirely peanut,
113
00:06:22,896 --> 00:06:25,172
Tree nut and dairy-free.
114
00:06:25,172 --> 00:06:28,482
To make the batter,
Workers first combine water,
115
00:06:28,482 --> 00:06:30,620
Canola oil and sugar.
116
00:06:30,620 --> 00:06:32,827
Then they add pureed banana
117
00:06:32,827 --> 00:06:35,793
And mix until the ingredients
Are well blended.
118
00:06:38,551 --> 00:06:40,862
They add wheat flour,
Then sea salt,
119
00:06:40,862 --> 00:06:44,310
Baking soda and preservatives
Such as citric acid,
120
00:06:44,310 --> 00:06:46,517
Routinely used
In packaged foods,
121
00:06:46,517 --> 00:06:50,379
To prevent the growth
Of bacteria and mold.
122
00:06:50,379 --> 00:06:53,379
The final ingredients
Are eggs
123
00:06:53,379 --> 00:06:56,034
And chocolate chips,
Not milk chocolate
124
00:06:56,034 --> 00:06:59,241
Because these snacks
Are dairy-free.
125
00:06:59,241 --> 00:07:01,689
Instead, chocolate chips
Are custom-made
126
00:07:01,689 --> 00:07:04,068
For this bakery
By a producer of certified
127
00:07:04,068 --> 00:07:06,103
Kosher pareve foods,
128
00:07:06,103 --> 00:07:07,344
Meaning the products contain
129
00:07:07,344 --> 00:07:11,620
Neither meat nor
Dairy ingredients.
130
00:07:11,620 --> 00:07:13,482
A pump moves the finished batter
131
00:07:13,482 --> 00:07:15,896
From the mixing bowl
To a large hopper
132
00:07:15,896 --> 00:07:19,724
That feeds the
Automated production line.
133
00:07:19,724 --> 00:07:21,310
At the start of that line,
134
00:07:21,310 --> 00:07:25,655
More than 620 loaf baking pans
Pass under spray nozzles,
135
00:07:25,655 --> 00:07:29,206
Which lightly grease them
With canola oil.
136
00:07:29,206 --> 00:07:34,344
This prevents the baked loaves
From sticking to the pan.
137
00:07:34,344 --> 00:07:36,586
Then the pans
Enter the depositor,
138
00:07:36,586 --> 00:07:42,137
Which drops 1.5 ounces of batter
Into each loaf cavity.
139
00:07:42,137 --> 00:07:47,586
This one batch of batter
Produces 6,666 loaves.
140
00:07:49,724 --> 00:07:53,034
The filled pans enter
A multilevel vertical oven
141
00:07:53,034 --> 00:07:56,551
In which they zigzag up
And down 13 baking zones
142
00:07:56,551 --> 00:07:59,448
Of varying temperatures.
143
00:07:59,448 --> 00:08:03,379
After 27 minutes,
The loaves are fully baked.
144
00:08:03,379 --> 00:08:05,241
However, they can't
Be packaged yet
145
00:08:05,241 --> 00:08:08,344
Because they're piping hot.
146
00:08:08,344 --> 00:08:09,896
So the next station on the line
147
00:08:09,896 --> 00:08:14,551
Is a multilevel vertical
Cooling chamber.
148
00:08:14,551 --> 00:08:16,310
Its fans draw out the hot air
149
00:08:16,310 --> 00:08:19,413
While blowers introduce
Filtered cold air.
150
00:08:23,413 --> 00:08:25,517
When the pans exit
The cooling chamber
151
00:08:25,517 --> 00:08:27,344
About 25 minutes later,
152
00:08:27,344 --> 00:08:29,586
The loaves are just
Slightly warm.
153
00:08:33,344 --> 00:08:37,034
A robot now descends
On two pans at a time.
154
00:08:37,034 --> 00:08:40,344
It jabs the loaves
With needles to lift them out
155
00:08:40,344 --> 00:08:43,379
Then withdraws the needles
To drop them on a conveyer belt
156
00:08:43,379 --> 00:08:46,931
That's ventilated to help
The loaves finish cooling.
157
00:08:49,206 --> 00:08:52,000
This belt transfers them
To a narrower one
158
00:08:52,000 --> 00:08:54,206
That leads
To the packaging area.
159
00:08:56,827 --> 00:08:59,827
There, workers line up
The loaves in single file
160
00:08:59,827 --> 00:09:03,241
On a track that leads
To the wrapping machine.
161
00:09:03,241 --> 00:09:06,172
Each loaf is roughly
3 1/2 by 2 inches
162
00:09:06,172 --> 00:09:08,655
And 1 1/2 inches high.
163
00:09:08,655 --> 00:09:12,172
Even though each one started out
As 1 1/2 ounces of batter,
164
00:09:12,172 --> 00:09:14,965
Some moisture evaporated
During baking,
165
00:09:14,965 --> 00:09:19,896
Reducing the final loaf
Weight to 1.4 ounces.
166
00:09:19,896 --> 00:09:21,965
Under the watchful
Eye of a sensor,
167
00:09:21,965 --> 00:09:24,000
The loaves enter
The wrapping machine
168
00:09:24,000 --> 00:09:27,103
Where printed transparent
Film envelops them.
169
00:09:30,344 --> 00:09:31,689
The two edges of the film
170
00:09:31,689 --> 00:09:34,758
Overlap slightly
Underneath the loaves.
171
00:09:34,758 --> 00:09:36,310
The machine seals the edges
172
00:09:36,310 --> 00:09:40,310
With a combination
Of heat and pressure.
173
00:09:40,310 --> 00:09:42,413
Then it simultaneously seals
174
00:09:42,413 --> 00:09:46,379
And cuts the film
In between the loaves.
175
00:09:46,379 --> 00:09:51,413
Each chocolate chip banana loaf
Is now individually wrapped.
176
00:09:51,413 --> 00:09:54,827
Workers pack the snacks
Into the retail packaging.
177
00:09:59,482 --> 00:10:01,827
The box moves
Into a glue machine,
178
00:10:01,827 --> 00:10:03,655
Which seals the flaps.
179
00:10:08,827 --> 00:10:11,655
The bakery conducts
Several quality control checks
180
00:10:11,655 --> 00:10:14,103
Throughout production,
For example,
181
00:10:14,103 --> 00:10:17,827
Testing the viscosity
And ph level of the batter.
182
00:10:17,827 --> 00:10:20,172
It also tests
The finished product.
183
00:10:20,172 --> 00:10:22,241
Once per hour,
They cut up a loaf
184
00:10:22,241 --> 00:10:24,931
And place the pieces
In a moisture analyzer.
185
00:10:24,931 --> 00:10:26,758
The correct moisture
Level ensures
186
00:10:26,758 --> 00:10:28,862
That the loaf has
A proper cake texture
187
00:10:28,862 --> 00:10:31,034
And isn't dry
188
00:10:31,034 --> 00:10:32,724
Because as much
As this snack needs
189
00:10:32,724 --> 00:10:35,310
To be safe for kids
With allergies,
190
00:10:35,310 --> 00:10:38,034
It also has to taste great.
191
00:10:48,206 --> 00:10:50,172
Narrator: vending machines
Are a common sight
192
00:10:50,172 --> 00:10:51,689
In public places.
193
00:10:51,689 --> 00:10:53,344
The first modern
Vending machines
194
00:10:53,344 --> 00:10:56,551
In 1880s england
Didn't sell food at all.
195
00:10:56,551 --> 00:10:58,517
They dispensed postcards.
196
00:10:58,517 --> 00:11:02,275
Nowadays, automated vending has
Come full circle with machines
197
00:11:02,275 --> 00:11:04,724
Selling not just food
But electronics
198
00:11:04,724 --> 00:11:07,620
And other consumer goods.
199
00:11:07,620 --> 00:11:08,620
Thirsty?
200
00:11:08,620 --> 00:11:09,896
Just select a drink.
201
00:11:09,896 --> 00:11:12,379
Enter its number
On the keypad.
202
00:11:12,379 --> 00:11:14,689
The led monitor displays
What you've chosen
203
00:11:14,689 --> 00:11:16,310
And how much it costs.
204
00:11:16,310 --> 00:11:18,206
Then insert the money.
205
00:11:18,206 --> 00:11:19,965
The monitor shows your credit,
206
00:11:19,965 --> 00:11:21,482
How much you've paid.
207
00:11:21,482 --> 00:11:23,344
The credit resets to zero
208
00:11:23,344 --> 00:11:25,172
When the machine
Releases your drink
209
00:11:25,172 --> 00:11:29,517
And returns any
Change you're due.
210
00:11:29,517 --> 00:11:32,034
The vending machine
Has a welded steel body
211
00:11:32,034 --> 00:11:35,724
Onto which workers assemble
The other components
212
00:11:35,724 --> 00:11:38,172
Such as the see
-through refrigerator
213
00:11:38,172 --> 00:11:41,862
And an lcd monitor
To display advertising.
214
00:11:44,689 --> 00:11:47,931
Workers assemble the machine's
Payment and display system,
215
00:11:47,931 --> 00:11:51,000
Starting with the machine's
Control board.
216
00:11:52,551 --> 00:11:55,689
They install the led monitor
And the keypad,
217
00:11:55,689 --> 00:11:58,344
Which are integrated
Into a single unit.
218
00:12:01,551 --> 00:12:04,172
After bolting the unit
Securely in its window
219
00:12:04,172 --> 00:12:06,655
In the housing,
220
00:12:09,482 --> 00:12:12,965
The workers screw the control
Board securely in place,
221
00:12:12,965 --> 00:12:16,931
Then plug the led monitor
And the keypad into the board.
222
00:12:19,724 --> 00:12:22,000
They install the coin acceptor.
223
00:12:22,000 --> 00:12:26,724
It can be set up to recognize up
To 16 different types of coins.
224
00:12:26,724 --> 00:12:28,551
When a customer
Inserts money,
225
00:12:28,551 --> 00:12:32,068
The coin acceptor transmits
The value to the control board,
226
00:12:32,068 --> 00:12:35,379
Which displays the amount
On the led monitor,
227
00:12:35,379 --> 00:12:37,793
Calculates it into
The purchase of the item
228
00:12:37,793 --> 00:12:39,172
And directs the coin acceptor
229
00:12:39,172 --> 00:12:43,034
To dispense any required change.
230
00:12:43,034 --> 00:12:46,241
Next, workers install
The bank note acceptor.
231
00:12:46,241 --> 00:12:49,034
It identifies the denomination
Of an inserted bill
232
00:12:49,034 --> 00:12:51,275
With an optical scanner and,
233
00:12:51,275 --> 00:12:53,517
To make sure
The currency is genuine,
234
00:12:53,517 --> 00:12:54,758
Measures fluorescent ink
235
00:12:54,758 --> 00:12:58,034
With uv light
And reads magnetic ink printing
236
00:12:58,034 --> 00:13:00,689
With
A magnetic scanner.
237
00:13:00,689 --> 00:13:04,241
It sends the value of the bill
To the control board.
238
00:13:04,241 --> 00:13:06,172
They plug the data
Transfer cables
239
00:13:06,172 --> 00:13:08,827
From the money acceptors
Into the control board
240
00:13:08,827 --> 00:13:10,758
Along with a cable
For the controllers
241
00:13:10,758 --> 00:13:13,586
That operate the machine's
Product release motors
242
00:13:13,586 --> 00:13:15,241
And the data transfer cables
243
00:13:15,241 --> 00:13:17,172
Coming from the two
Coin hoppers,
244
00:13:17,172 --> 00:13:21,758
Which collect the inserted coins
And dispense change.
245
00:13:21,758 --> 00:13:25,586
Then they close up
The machine with cover panels.
246
00:13:25,586 --> 00:13:27,862
A worker constructs
The product feed trays
247
00:13:27,862 --> 00:13:31,068
That go into the vending
Machine's refrigerator.
248
00:13:31,068 --> 00:13:33,379
The first step
Is to attach partitions
249
00:13:33,379 --> 00:13:37,206
To a back panel to form columns.
250
00:13:37,206 --> 00:13:39,482
Each column's width is set
To the dimensions,
251
00:13:39,482 --> 00:13:43,827
Weight and type of packaging
Of the product it will dispense,
252
00:13:43,827 --> 00:13:46,310
From small featherlight
Bags of chips
253
00:13:46,310 --> 00:13:49,793
To heavy glass beverage bottles.
254
00:13:49,793 --> 00:13:54,517
A feed tray can have up
To six columns.
255
00:13:54,517 --> 00:13:57,931
The trays are constructed
Entirely of stainless steel
256
00:13:57,931 --> 00:14:00,344
Because it withstands
Refrigeration temperature
257
00:14:00,344 --> 00:14:03,206
And doesn't rust
When exposed to moisture.
258
00:14:06,620 --> 00:14:09,689
Workers install a motor
At the back of each column.
259
00:14:09,689 --> 00:14:12,068
Once the tray's installed
In the fridge,
260
00:14:12,068 --> 00:14:15,344
Those motors plug into
The control board.
261
00:14:15,344 --> 00:14:18,103
When the customer pays
For the selected product,
262
00:14:18,103 --> 00:14:21,137
The board activates the motor
For the corresponding column
263
00:14:21,137 --> 00:14:23,413
To release the product.
264
00:14:23,413 --> 00:14:25,689
Side-by-side columns
Designed to be stocked
265
00:14:25,689 --> 00:14:28,862
With the same product
Have linked motors.
266
00:14:28,862 --> 00:14:31,068
That way, if one
Column sells out,
267
00:14:31,068 --> 00:14:35,655
The linked one with more
Of the same product kicks in.
268
00:14:35,655 --> 00:14:39,206
Each motor moves the product
With a steel drive spring.
269
00:14:39,206 --> 00:14:42,620
There are seven different
Sizes of springs.
270
00:14:42,620 --> 00:14:45,482
Workers install the size
That has the correct spacing
271
00:14:45,482 --> 00:14:46,689
Between the rolls
272
00:14:46,689 --> 00:14:48,275
That corresponds
To the dimensions
273
00:14:48,275 --> 00:14:52,034
Of the product being
Dispensed from that column.
274
00:14:52,034 --> 00:14:54,344
Once the customer pays
For the selection,
275
00:14:54,344 --> 00:14:57,344
The motor rotates
The spring 360 degrees
276
00:14:57,344 --> 00:14:59,379
To release the product
277
00:14:59,379 --> 00:15:02,586
And move the one behind it
To the front of the line.
278
00:15:02,586 --> 00:15:05,586
Once all the product feed
Trays are installed,
279
00:15:05,586 --> 00:15:07,241
Workers adjust the refrigerator
280
00:15:07,241 --> 00:15:10,620
Thermostat and stock
The products.
281
00:15:10,620 --> 00:15:12,551
Then they test the machine.
282
00:15:12,551 --> 00:15:16,034
First, they purchase a product
With paper currency.
283
00:15:16,034 --> 00:15:18,241
They make sure
The bills feed smoothly,
284
00:15:18,241 --> 00:15:20,034
That the bank
Note acceptor sends
285
00:15:20,034 --> 00:15:22,620
The right data
To the control board,
286
00:15:22,620 --> 00:15:25,965
That the board calculates
The transaction accurately
287
00:15:25,965 --> 00:15:29,689
And activates
The correct motor.
288
00:15:29,689 --> 00:15:32,413
They run the same test
With the coin acceptor
289
00:15:32,413 --> 00:15:35,275
To make sure its sensors
Correctly detect the coin,
290
00:15:35,275 --> 00:15:38,689
Dimension,
Weight and chemical composition
291
00:15:38,689 --> 00:15:40,655
And transmit
Accurate information
292
00:15:40,655 --> 00:15:43,724
To the control board,
293
00:15:43,724 --> 00:15:46,413
All this to ensure
The vending machine customers
294
00:15:46,413 --> 00:15:49,000
Get exactly
What they paid for.
295
00:16:02,413 --> 00:16:06,206
Narrator:
Dive computers help divers
Safely return from the deep.
296
00:16:06,206 --> 00:16:08,689
These wrist computers
Keep tabs on the time
297
00:16:08,689 --> 00:16:10,137
And depth of the dive.
298
00:16:10,137 --> 00:16:12,517
And they calculate
A safe ascent.
299
00:16:12,517 --> 00:16:16,172
The journey back to the surface
Must often be done in stages,
300
00:16:16,172 --> 00:16:19,862
Or the diver could fall victim
To decompression sickness.
301
00:16:23,275 --> 00:16:25,517
A dive computer is
Something someone wears
302
00:16:25,517 --> 00:16:27,896
When they're ready
To take the plunge.
303
00:16:27,896 --> 00:16:30,206
Strapped to the wrist
Like a watch,
304
00:16:30,206 --> 00:16:34,172
It provides critical safety
Data during the dive.
305
00:16:34,172 --> 00:16:37,862
They start with panels
Of four printed circuit boards.
306
00:16:37,862 --> 00:16:39,827
A technician confirms
That the tracks
307
00:16:39,827 --> 00:16:42,896
And pads are correctly located.
308
00:16:42,896 --> 00:16:45,896
A conveyor then takes one of
The panels into a machine
309
00:16:45,896 --> 00:16:47,448
That precisely positions
310
00:16:47,448 --> 00:16:50,068
A metal mesh
Stencil over it.
311
00:16:50,068 --> 00:16:52,379
An automated squeegee
Spreads solder paste
312
00:16:52,379 --> 00:16:53,827
Onto the circuit boards
313
00:16:53,827 --> 00:16:57,137
Through the open areas
Of the stencil.
314
00:16:57,137 --> 00:16:59,206
The solder paste
Will act as glue
315
00:16:59,206 --> 00:17:03,034
For over 100 tiny
Electrical components.
316
00:17:05,344 --> 00:17:11,275
Next, the circuit boards receive
Those electrical components.
317
00:17:11,275 --> 00:17:14,517
A robot peels them
Off plastic strips
318
00:17:14,517 --> 00:17:16,413
And places them on
The soldered areas
319
00:17:16,413 --> 00:17:22,137
At an impressive rate
Of 13,000 pieces per hour.
320
00:17:22,137 --> 00:17:24,448
The parts
Include microprocessors,
321
00:17:24,448 --> 00:17:27,206
Sensors and memory chips.
322
00:17:27,206 --> 00:17:29,448
Then the circuit boards
Head into an oven
323
00:17:29,448 --> 00:17:33,310
With several different
Heating and cooling zones.
324
00:17:33,310 --> 00:17:35,172
As they travel
Through these zones,
325
00:17:35,172 --> 00:17:36,862
The soldering particles melt
326
00:17:36,862 --> 00:17:40,689
To bond the components
To the circuit boards.
327
00:17:40,689 --> 00:17:42,551
Passing through
The cooling zones,
328
00:17:42,551 --> 00:17:43,931
The solder hardens.
329
00:17:43,931 --> 00:17:48,172
And this solidifies the bonds.
330
00:17:48,172 --> 00:17:50,206
The circuit boards
Have now received
331
00:17:50,206 --> 00:17:52,275
All of the necessary parts.
332
00:17:55,241 --> 00:17:58,000
A technician places
The panel of circuit boards
333
00:17:58,000 --> 00:18:00,896
In an automated
Optical inspection machine.
334
00:18:00,896 --> 00:18:03,482
Here, a camera takes
A picture of the panel
335
00:18:03,482 --> 00:18:05,551
And sends it to a computer.
336
00:18:05,551 --> 00:18:07,620
The computer scans
The circuit boards
337
00:18:07,620 --> 00:18:09,241
For missing components,
338
00:18:09,241 --> 00:18:13,344
Positioning errors
And soldering defects.
339
00:18:13,344 --> 00:18:15,068
If there are no flaws,
340
00:18:15,068 --> 00:18:18,206
The panels move on
To a programming station.
341
00:18:18,206 --> 00:18:22,448
Here, a technician
Positions them under probes.
342
00:18:22,448 --> 00:18:24,689
The probes descend
And load software
343
00:18:24,689 --> 00:18:26,965
Into the microprocessors.
344
00:18:26,965 --> 00:18:28,586
This brings them to life
345
00:18:28,586 --> 00:18:30,137
And enables them to control
346
00:18:30,137 --> 00:18:34,034
All of the board's functions.
347
00:18:34,034 --> 00:18:36,379
Another technician trims
And cuts the panels
348
00:18:36,379 --> 00:18:38,448
Using circular saws.
349
00:18:40,275 --> 00:18:43,000
She then punches out
The four round circuit boards
350
00:18:43,000 --> 00:18:44,724
And transfers them to a tray
351
00:18:44,724 --> 00:18:48,137
That has an electrically
Conductive surface.
352
00:18:48,137 --> 00:18:49,862
The surface protects the boards
353
00:18:49,862 --> 00:18:52,172
From mechanical
And electrical shocks
354
00:18:52,172 --> 00:18:53,724
Until they're ready
To be assembled
355
00:18:53,724 --> 00:18:56,655
Into the dive computer module.
356
00:18:56,655 --> 00:18:59,931
Now the fabrication
Of that module begins.
357
00:18:59,931 --> 00:19:04,517
The technician places a buzzer
Mechanism behind a backlight.
358
00:19:04,517 --> 00:19:06,206
She transfers the two of them
359
00:19:06,206 --> 00:19:09,517
To the reverse side
Of a display screen.
360
00:19:09,517 --> 00:19:12,413
She places a plastic
Framework on top.
361
00:19:12,413 --> 00:19:15,206
And she inserts rubber
Connectors in it.
362
00:19:15,206 --> 00:19:17,344
These little rubber parts
Will make the connection
363
00:19:17,344 --> 00:19:22,206
Between the circuit board
And the digital display.
364
00:19:22,206 --> 00:19:24,620
The next assembler inserts
The circuit board
365
00:19:24,620 --> 00:19:26,551
Into the digital display unit.
366
00:19:31,482 --> 00:19:33,724
She installs a temporary battery
367
00:19:33,724 --> 00:19:36,034
And checks the digital monitor
To confirm
368
00:19:36,034 --> 00:19:37,931
That it's functional.
369
00:19:39,344 --> 00:19:41,620
Satisfied that it's in good
Working order,
370
00:19:41,620 --> 00:19:44,000
She sets it aside temporarily.
371
00:19:48,275 --> 00:19:50,241
In the next stage
Of production,
372
00:19:50,241 --> 00:19:51,275
The worker removes
373
00:19:51,275 --> 00:19:53,034
Any dust particles
From the screen
374
00:19:53,034 --> 00:19:55,172
Using blasts of compressed air.
375
00:19:57,275 --> 00:19:59,000
She snaps the dive
Computer module
376
00:19:59,000 --> 00:20:00,965
Into a tough plastic case
377
00:20:00,965 --> 00:20:05,448
That's designed to withstand
A lot of water pressure.
378
00:20:05,448 --> 00:20:08,068
She cleans a glass face
Plate and places it
379
00:20:08,068 --> 00:20:10,655
Over the digital screen.
380
00:20:10,655 --> 00:20:15,137
This face plate will protect
The screen from water.
381
00:20:15,137 --> 00:20:17,862
The next part
Is a metal bezel.
382
00:20:17,862 --> 00:20:19,413
It surrounds the face plate
383
00:20:19,413 --> 00:20:22,000
And will be used
To secure it to the casing.
384
00:20:24,448 --> 00:20:27,137
She flips the assembly around
385
00:20:27,137 --> 00:20:29,965
And screws the bezel
To the case from the back.
386
00:20:34,379 --> 00:20:38,137
She inserts the computer battery
Into a titanium back plate.
387
00:20:44,551 --> 00:20:46,344
She then installs
The battery assembly
388
00:20:46,344 --> 00:20:49,827
In the back of the module
And secures it with screws.
389
00:20:52,413 --> 00:20:56,172
This completes the dive
Computer module.
390
00:20:56,172 --> 00:20:59,137
All that's left is
To attach the wrist strap,
391
00:20:59,137 --> 00:21:02,275
And this dive computer
Is ready to probe underwater
392
00:21:02,275 --> 00:21:05,310
And provide
Critical safety information.
