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

ICT and specifying PCBA testing

Electronics Forum | Fri Mar 26 11:31:34 EDT 2010 | rway

I have been using ICT for a number of years. It is still a viable resource for catching defects in the production process. AOI doesn't catch everything, such as bridging on QFN or J-lead devices (this will depend on the type of AOI and camera syste

I like MpM personally - run forever and programming is easy and leads you through it. It's hard to miss a step of programming with MpM software. DEK's a little harder (for me) but still very nice controls. The pluses of DEK - DEK has a high freque

Electronics Forum | Thu Jul 18 17:06:19 EDT 2019 | spoiltforchoice

I can't imagine anything more tedious than continuously swapping feeders during a build (unless your panels are 10mins++) and the very suggestion this was a good idea when were were looking at MY's was comical to me. You should expect all TP series

Electronics Forum | Thu May 25 01:46:10 EDT 2023 | frankchan

Hi, I would recommend something from 21 Century at least. Considering it's mostly small batches there's no reason to raise the budget to purchase the Newest series. I think the principle here is something that'll do and do a nice job. If you are a Ya
