Hello technetters!
Well thank You for your enthousiastic answers concerning
your identities. I'll give you some details about my
occupations ounce I get rid of some fires here (it's funny,
nobody mentioned firefighter!!!).
Some people here are getting pretty nervous about one
IPC-A-610 criteria here and honestly I dont know what
what to tell them to ease their worries.
Par. 3.2.4 says that class 1 & 2 permits coating meniscus
of capacitor to be mounted into PTH. But is'nt there a
risk of preventing the solder to be conform to criteria
4.1 table 1 (saying that the solder must fill 75% of
the hole)? What is the risk of not respecting this criteria
(3.2.4). Personnaly I would fear craquing for the capacitor
on the long run (plus the solder fill), this thing will be submit
to constant vibrations (It goes on a train, near the braking system).
So I would prefer to have it above the meniscus. But here they
are concerned with the overall costing... Well I guess I need
some of these 5000 years of experience now!
Thank You! See you around!
