Fellow technetters:
My company is beginning its research into the wonderful world of organic
solderability preservative coatings. Our goal being to implement this on
the circuit boards in the near future. I am looking for any and all
information that anyone may have(I have a pile of articles 12" high) with
use in production. I am especially interested in:
What type of coating is on the board
Number of heat excursions you have and does the coating live up to its
published cycles
Special handling procedures(operators) Board storage, time in
production
How you flux/profile/anything you did to get the topside fillet
Use of nitrogen?
Have you had solderability problems and how were they handled
Do you specify board cleanliness, coating brand, thickness on the
print and how is it verified.
Thru-hole components scrap the inside of the barrel when inserted, any
problems here with soldering
Any special tricks done at the wavesolder
Any and all information is appreciated
Thanks
Ed Holton
