Hi Randy,
Smoke damaged assemblies? Reminds me of something that actually happened
to me about 8 years ago. I was working at a contract assembly company called
Comptronix in the San Jose facility at the time (Comptronix has since been
bought out by Sanmina by the way...).
We had worked a day shift on a Saturday. Sunday morning at about 6:30am I
got a call from one of my co-workers asking me to get up and come down to the
plant because it had caught fire very early Sunday morning (around 1:30am),
and I needed to come down to help clean up. After he finally convinced me that
he wasn't just pulling my leg and that it really did catch on fire (he was
always joking around with me, most of the time I fell for his pranks), I came
down to the plant.
When I turned into the parking lot and saw the fire trucks and hoses all
over the place, I knew then he wasn't kidding at all. What had happened was
that the one of the water cleaners we had was some old unit (I can't remember
the name of the unit unfortunately), that didn't have any sort of automatic
power shutoff to the water heaters if you happened to boil the water out of
the tanks...which was exactly what happened.
The operator had shut down the the conveyer, the air blowers, wash and
rinse pumps after working Saturday, but neglected to turn the heaters off. The
cleaner was constructed mostly out of poly, and when the water finally boiled
out, it proceeded to meltdown and burn setting off the sprinkler system. It
contained the fire to only the cleaner area, but there was quite a bit of
product in various stages of assembly on the production floor which was
exposed to a lot of smoke and water from the sprinkler system.
We all rolled-up our sleeves and started cleaning things up, it was a
mess let me tell you! People from the different functional areas on the
production floor began to check out their equipment to see if it still worked
or not. We were still using Freon back then and we had a in-line Detrex
cleaner. We took all the assemblies that had been on the floor and ran them
through the cleaner. I sampled them with a omega meter to be sure that we were
cleaning them okay.
We took the assemblies that we had some sort of ICT or functional test
for and ran them back through the test even if they had already been tested
good once, or if they were at the stage of assembly that they could be tested.
The ones that hadn't made it that far in the process were que'd back up again
in the stage where it was at before the fire.
After a lot of work, we finally started to see light at the end of the
tunnel. On Monday our customers were called and informed what had happened,
and what we were doing with the product that was on the floor. Everything that
had been on the floor was put under real scrutiny by us, and by our customers.
After all was said and done, the only boards that were lost in the fire
was about 3 tilt-racks worth that had been setting on a table right next to
the exit end of the "slag pile" that once was a water cleaner.
(the sound of happy ending music...hehehe)
