First, SM-782 elates to surface mount pads. So, expecting to find PTH design rules there is a bit of a stretch. Search the fine SMTnet Archives for similar threads. For instance here�s one from last week: http://www.smtnet.com//forums/index.cfm?fu

Hi mates, ain't we all forgetting something? this bloke who posted this thread, has not even specified what his "stability-variation" issue is all about? defect/quality variation? downtime variation? CPH variation? etc... Just read this bloke's th

Hi, I would be interested in the data, and I after our experience with batch convection I am quite skeptical. I would be very interested in temperature plots. What I would like to see before I ever considered a batch convection oven is how the oven

I get a Timeout waiting for nozzle changer vacuum buildup failure every time I go to run my 1998 GSMx machine. The problems seems to be that once in a while (it seems to be random) the spindle does not line up exactly in the center of the nozzle cha

Glen: As I mention in an earlier response in this thread, I think someone at Steve's plant (or may be in his packaging spec for the fabs) is doing something to leave a residue, but I'm also thinking solder mask ... ENIG can be applied before or aft

Alberto: Consider Dymax 911. It�s wave solderable and passes Cl ion, copper mirror, SIR, and electromigration tests. We have heard good things about Masterbond uV curables, but have not looked at them. 911 doesn�t cure very deep into the little d

Pascal: Responding to your questions: 1 Do we have to dry the PCB after cleaning (sic)? Generally, nothing says you have dry the PCB after aqueous cleaning. Along this line, I received several thoughtful responses when I posted a similar thread.

We had an interesting problem this week that is along this thread. Had a project that had the same resistance value components, but one component was a 1% tolerance and the other was a 1/2%. Guess what? the operator got them mixed up. We have a first
