Genny, you may want to look at the brds you will be running and identify the various packages. I do not know what a standard package is. Most chip resistor and capacitors, 0402, 0603, 1206, 1210's are on 8mm feeders, but ic's vary quite a bit. Also r

Dave, I've had a few intersting conversations with Dr Lee, now there's a guy who know's stuff, but as it turn's out even he doesn't have all the answers on why things void. Many of his papers point towards oxides or contamination on the ball, so age

Hi everybody, This is a simple posting to initiate a discussion on different ways to troubleshoot, improve, and control the Stencil Printing Process SPP in SMT manufacturing. There are many SPC, ANOVA and other analysis techniques that provide insi

Like Russ, I am also curious about the 100% fill requirement. On any thick, high mass board the key is getting as much heat as possible into the board. If you get the board to the proper temperature, solder will flow just about anywhere. As an alte

If someone searches the archives and finds a thread with information that they would like to know more about, how can we(at SMTnet.com) make it possible for them to ask the question in the context of the message and it's threads? Or should they not b

Steve , I agree with all the responses you have received. Randy Villeneuve is absolutly correct in all of his assesments and I would consider him an expert with the process , Gris is correct about adding a "heat sink" to the process complicating pr

It is surprising how a simple question sometimes reveals complex issues. It seems from reading many replies that an employee wearing a walkman while working is making a statement about his attitude toward his work and his employer. This is similar to
