Solderability tests for Gold finishes

Solderability tests for Gold finishes | 6 December, 2004

Hi, I understand that solder dipping of gold plated units (PCB or component lead) is not the ideal solderability test (leaching of gold in the solder bath being one reason).

Would anyone have recommendations as to the ideal solderability tests for gold plated PCBs and components.

ANSI/J-STD-003 - Solderability Tests for Printed Boards is widely accepted. That's it, that's the list. If you email us your email address, we'll give you someone to call.

Without knowing the number of boards that you plan to run across your wave, in most instances, it will take a very long time to contaminate your pot with gold by doing solderability testing. There is lots of metal [GT 500 pounds] in the pot and a very thin [LT 8 thou] gold thickness on boards.

Thanks Dave,

That answers my question. I didn't think either that the qty of gold in platings would be enough to contaminate the solder pot. I wanted to make sure that leach test is a valid test for gold finishes.
