Alloy for solderballs search ? | 28 April, 1998

We want to produce BGA�s which will be see burn in conditions of 140�C / 24h active tested. Now we think about problems for the solderball uniformity. Does anybody know about problems or about special solderball alloys for such productsconditions ? Any help welcome.

Hello Achim, I'll put a URL to an Alpha Metals web page that has a list of technical articles that are precisely about BGA spheres...you'll need Adobe Acrobat to read or print them though. If you don't have it, don't worry, they have a link right on the page that the articles are on where you can download it. They're pretty good articles, they get into different alloys and stuff. Hopefully they will help you out... -Steve Gregory-
