Paul, I've got a third-level ISO Stencil Specification procedure that I did at a past employer that I'll send you...it also deals with the DEK-265 printer (which is what we used) when I talk about frame sizes and image positioning, but you can edit i

One more question, how can AOI detect if the frame of two two-part shield has the cross on top of it for Pick'n'place? I mean has two part shield helped you in term of inspection or in term of better soldering? Or did you put it for the satisfaction

As you already know, it depends on the paste. There isn't really a rule of thumb, but less time exposed it better. The issue is the flux exposure to the air and ambient conditions. The flux can evaporate or absorb moisture from the air. If the paste

Below is an email that I copy and pasted from my customer's engineer about his concerns with the issue of the chips not reflowing (which is why I was asking about X-ray the chips to make sure they reflowed): Can you let me know your thoughts on his

Joe: Lemme see, you�re talking about controlling your manufacturing process within 4.6 defects per 100 opportunities or a 4,600 dpmo rate, a cumulative 99.95 acceptance rate, or a �2 sigma process, right? So, it�s fairly basic stuff, eh? First, yo

Our solder ball problem is linked to moisture. If the paste sits on the board too long (especially during our humid summer months) we experience the problem. As far as the problem being specific to components or areas of the board, maybe some of th

Q1 Can anyone explain to me what is the clean and non clean solder? A1 The trend away from CFCs has lead many users to evaluate switching to no-clean soldering processes. The term "no-clean" is actually a common misnomer when used to describe a flux
