We allow it (water only) as long as the bottle has a closed lid. We determined this to be acceptable since water is already present at each station for solder iron cleaning. We allow no other eating or drinking of any type. Russ

personally, I do allow. usually, they will do some design for manufacturability change. this cannot be avoided. I have read an interesting article talking about this question, maybe you can check: http://www.starivergroup.com/News/info.aspx?itemid=10

Wolfgang: Sure, stacking chip components is common practice in prototyping, as you say, but it's not good practice for production work. Documentation: * ANSI-IPC-275 does not allow stacking * MIL-STD-2000A does not allow stacking * J-STD-001B is u

What is your opinion on the current debate about lead in CRTs and not allowing them in landfills?

At my last company, we installed in-line testers. They worked very well, but there were some issues to be addressed; 1 - Boards had to be cool enough to go through ICT or we had false failures. 2 - We used no-clean flux...enough said about that. 3
