I realize this is a SMT forum, but I have another problem related to electronics assembly and hope there will be someone out there that can save my life (this time). We build quite a few VME assemblies to which we attach a SAM board. Fairly standard

Selective Wave Soldering

Electronics Forum | Tue Apr 07 09:51:31 EDT 1998 | Gary Simbulan

Good Morning everyone. Per repeated suggestions I have been reading back issues of SMT and Circuits Assembly magazines. I have just read an article concerning selective wave soldering which I understand is to be used when active SMTcomponents are a

Re: Reflow of flex circuit

Electronics Forum | Thu Mar 05 16:25:27 EST 1998 | Brian Stumm @ ETS

| I am looking for information on reflow temps for a flex board. There is only one 6 pin IC but the board has a 3M double sided tape. | Is it possible to reflow without damaging the tape. Any suggestions? Do you have a profiler for your reflow oven?

Looks like (so far) we have a concensus. Follow the paste manufacturers guidelines on storage. Normally, refrigeration is required to achieve max shelf life between 3 and 6 months in original closed container. Water-wash pastes are much more active t

Re: SMT at home?!
