First, speaking only of the shop this person is employed with...of them, not
for them...we may sell the boards cheap...but the boards are not cheaply
fabricated...lets keep that understood...(grin)

Second, how did you come across one of our Failure Analysis Procedures
anyway??? Is their some espionage going on around here...hmmmm

While that method may seem comical to many...truthfully...those type
approches to identify causes, effects, conditions, etc... have in my
experience provided much valued information... With product in the
field...it's usually the jolting, jarring, twisting, pulling, banging
against...etc that will cause the failure...so every now and then go ahead
and smack a board against the wall...see what falls off...you might learn
more about your process that way...

And interesting afterthought...we retested samples from a batch of boards
that where ran over by a UPS forklift...after falling off of one of their
suspended conveyors...20 feet to the ground...scattered across the
wharehouse floor then wrapped up by their employee in shrink-wrap and
returned to us as-is a week later...they soldered well also...yes...I was a
little bored that day...and curious...
