Dear Superlen, I noticed this post maybe a little late, but I seem to recall an email conversation with a user that mentioned a bug in my SSA format in PCBSynergy. So I checked back through my source and here is an example of the first part of the

| I'm trying to get a feel for what the industry is doing with regards to collecting assembly defect data in the SMT/PWA process. Is it sampling or 100%? What are the points within the process where critical assembly defect data is collected. We run

Hello, I know I will probably get a dozen "check the archives" answers, but what the heck. What is YOUR typical polarity mark for SMT devices? Do you use silk screen or cut a corner off a pad? How do you identify pin one on ICs? Let me know and

Our line is on overtime so it makes it difficult to actually work on this thing. It seems yesterday and last week it only froze about 6 times in all. When we actually have a few minutes one of us will get in there and check it out. Also, I talked to
