Electronics Forum | Tue Sep 17 15:47:04 EDT 2013 | 18424

Good day all, I wanted to get a quick poll from the folks running SAC305 in their selective soldering equipment. How are final results? How repeatable is the process, any machine related failures? pumps? nozzles? etc... I am just looking to get a

Hey all, I've made a post in the past about us expanding to a new space, but I wanted to do a new post with specific questions. We currently have a DEK 265, Phillips Opal Xii, and a Heller 1500. Our main reason for expanding is to have a lead-free

Possible to mix a No-Clean solder and a Clean solder process

Electronics Forum | Thu Apr 05 17:06:11 EDT 2018 | stephendo

We recently got a batch wash machine that can use a chemical cleaner. (not a saponifier). NOW I feel confident cleaning no clean boards. Without a machine that can heat water and use a proper cleaning agent, I would not trust cleaning no clean boards

I can't seem to locate any information/concerns about moisture entrapment in IC packages on the promary side in a double sided SMT assembly using water soluable solder paste when soldering the second side. A typical process would assemble/reflow/cle

Desoldering of TSOP and TSOJ

Electronics Forum | Fri Jan 08 02:27:00 EST 1999 | Kwang-Seong Choi

HI! I am a package engineer in Korea. I have some reasons to desolder excessive solder at the lead of TSOP and TSOJ after removing them from the board. The way with solder wick is too time-consuming and depends on the operator. Does anyone know the

CSP and BGA soldering difference.

Electronics Forum | Thu Apr 05 08:44:45 EDT 2007 | ck_the_flip

"Guest" is right, actually. CSP's are essentially BGA's, but typically the pitch and ball diameters are much smaller and in some cases, the pads of the CSP's can not be screen printed. If that's the case, you'd have to have flux-dip capabilities on
