Eva,
that is big mis-understanding of the certification: it is not intend
to teach employee (training) how to solder. the responsibility
should be EMS in house training due to (1) equipment difference (2)
back ground difference (3) type of the job they do (job shadowing is
key). IPC course is not intended as short cut to those. When I 1st
join a company (IBM), although I was electronic material in major, I
still go through job shadow rotations, that took almost 1 month,
including SMT line, repair, pick/place, inspection, wire bonding, die
attach, etc.etc. of course, QA inspection (at time, there is no IPC
certification requirements - early 90s)... EMS work force can be vary
great deal - from excellent due to good experience with many
companies and different kind of design/assembly, to "not so good" -
very limited knowledge on basic phase diagram of solder melting for
example.. it couple with poor QA and FA (not due to capability of
operating good machine, especially, new machine that automated many
functions, but lack of knowledge of understand data... such as SEM
30kV EDX showed no difference of gold pad contamination, even the
secondary electron image showed a black spot on the pad - it took a
long time to explain the accelerated voltage vs electron penetration
depth and signal strength... although I was told those chaps fully
trained by SEM equipment vendor...). it your customer wants basic
solder training but lack of in house capability, they either in the
wrong business, or they need to invest some serious money to haul
external expert (not SMT equipment vendor, or solder iron vendor) to
bring up to speed. IMHO. IPC certification training is not the
right course.
my 1.5 cents.
