I'm having a difficult time understanding the need anymore for a West Coast show going forward. Other than tradition, let's face it.....there is much more going on in the midwest these days. All and all....I don't see much of a future in Southern C

these assemblies getting depaneled? ICT? any fixtures or anything? I would check your print and placement equipment and make sure there are no support issues as well. But I believe you mentioned fractures so that would be happening after the reflow

Taking a pole for s&g's. Just got out of a meeting and the customer said the solder joint of the parts only occurs at the fillet. "Without the triangular part of the solder there would be no solder joint." These where actual words spoke. I know d

They must have ended up with a bunch of them in stock because they never quoted a price that low to us, of course Im getting older and my memory is not that great anymore. If you have even decent machine shop, make your own. The factory one is made o

If the attack was unwarranted I apologize. I still stick to my answer. Unless the board shop can get rid of it you have to find a way to deal with it. Etching trace paths into the stencils is inexpensive and works just fine. If you do not have the ti
