The
Fender Mexico Factory A
Photo Tour Amplifier
Electronics and Final Assembly As
the amplifier cabinets were being made, the electronics were
also being made, and assembled. They both meet together
later in the building process to create a complete amp.
But that’s not all,
as we will see. |
| This
machine inserts the individual components into the circuit boards.
Years ago I saw a similar
machine in the, now defunct, Packard Bell plant. They were
making Intel motherboards, and also boards for Zenith Data
Systems and NEC with it.
Those “ribbons” coming
out of the side are the components stuck by tape.
|
 |
 |
The boards
are then put on carts. |
They
then go through this machine, called a Wave Soldering machine.
It solders all the connections all at once. |
 |
 |
But that’s
not all. Each solder joint is individually inspected and
if it needs to be redone, it is soldered by hand. |
| Next, the circuit board
is hooked up to a computer and run through a battery of tests.
Test results are then
benchmarked off of stored results. If it falls within
the tolerance levels, the board is passed. |
 |
 |
The circuit boards are
then assembled in their metal enclosures; wires and controls
are added to prepare it for final installation in the cabinet. |
| Next the speakers and
the amplifier unit is installed in the cabinets, completing
the entire amp. It’s now ready to go. Almost.
Notice the two small
white rooms at the top left of the photo. We will discuss
them next.

Inside each of
those little rooms, you find the quality control person.
The rooms are sound proofed for isolation.
The quality control
person CHECKS EACH AND EVERY AMP. Not spot-checks them.
He runs music of his
choice through every amp and listens to setting, every control,
and every on-board effect. If it does not sound exactly
right, it gets rejected. They then figure out what is
wrong with it.
When he checks Bass
amps, he has to plug a bass into each one to check for rattles.
You can guess he had more than just a bass on the wall, though.
|
| Maybe your
thinking that he does not really reject anything. Not true.
The day we were there, there were two rejected DeVille’s sitting
on the floor. |
Now
What? Yes, what you have been waiting for... Guitars.
