Do you happen to know where I may find a supplier for the "little mirror"? Google didn't produce relevant search results for Mentor. My method of inspecting possible bridging under a BGA involved a small flashlight placed up against the edge of the

Your solders could have vasty different liquidous points. Check with your suppliers to determine the appropriateness of the materials you have selected. Awhile ago Jim Zanolli at Teka hosted an OnBoard Forum here at SMTnet. He'd be happy to give y

It looks like we'll have to go the conductive process tray route. I looked through web sites for Brick Container and several other esd suppliers and did not find anything that would work. I saw the tray you mentioned in my Techni-tool catalog, but wa

Our old friend Bob Willis posted the best procedure for determining wave solder recipes at his site [ http://www.bobwillis.co.uk ]. In the "Download" section, look for "Setting up Wave Soldering System (Plain Text Format)". It was written, last we

A lot of this depends on the initial quality of the OSP. I have had boards that aren't any good being stored air tight for one day. While believe it or not, I recently used boards that were opened and sat for 1 1/2 years and we built them with no pr

With a eutectic ball, you'll see about a 50% collapse. This negates that .008" issue you're referring to. With a high temp ball, you don't enjoy the same freedom regarding ball collapse. Dave is correct, though. We recently got IBM to sign up to
