Hello,
I had some difficulty with my E-mail just around the time I first
posted this. The problem is corrected , therefore here it is again.

Hello,
I am interested in testing solderability of printed circuit boards.
There are 5 techniques mentioned in ANSI/J-STD-003 "Solderability
Tests for Printed Boards". They are : Edge dip, rotary dip , float,
wave, and wetting balance. The first three are done in a solder pot.
There is another method called "SERA Testing" that is not mentioned.
Do any of these prove reliable in predicting a boards performance
during assembly? Is it better to age the samples before testing? If so
then is steam aging the best method?
Interpretation of results seems to have a certain amount of
latitude. Is there a comprehensive authoritative work on the subject.
Some of the contacts for equipment manufactures mentioned in
section 6 of the document mentioned above are no longer valid. Are
there still sources for this equipment?
There is no source for wave solder testing equipment listed. Is
there a lab scale unit available?
I am interested in presenting a paper in September at the IPC
Summit on PWB Surface Finishes and Solderability in September titled
something like "Survey of Solderability Testing Techniques". I plan on
using information gathered on TECHNET in this paper. If you have
information and wish to assist please contact me.
Thanks
Rich
