I do not know what software version you have, but on older versions it is best to have a mounting inspector set to be the primary and then mask out all labels and solder so it just locates the part. Then add another mounting inspector for looking at

I'm looking for a typical SMT placement defect rate from others in the field so I can judge whether or not we are in an acceptable range. If I give you a board with 200 components (0603, 0805, SOICs, 20mil MSOPs, tantalums, DPAKs and a few 20mil fin

Solder paste selection can have a huge impact on size and quantity of voids. Talk to a few suppliers and ask for their recommendation on low voiding formulas. Pick a few of your top candidates and then perform a DOE to see who has the best result. S

It looks like a giant dpak device but with 5 leads. The problem is that on approx 3% of our boards one more pins are open circuit. It appears that the pins are not in contact with the pads. Board is HASL finish IR oven Paste Koki 953i. If you have a

Management is talking about the ability to do all our assembly in house. I would assume that realistically that we would eventually limit it to a few key products, but we are a high mix, relatively low volume company with volumes going up. We have

Thanks again Bobpan for all of your help. I hope some of my questions are dumb ones. Regarding "first", the QA error 0, you were right. In checking the setup, for some reason theta was 65227 instead of the 0 that I thought I had set. Regarding "sec

In trying to have things run smoothly with placement, I have to do a lot of theta adjustment to get the rotation right during placement. Even if the part looks good on the PnP machine screen sometimes it places differently than what is shown. If I u

As Evitomov says, provided you check everything is setup correctly there should be no issue. There can be some variation between manufacturers as to how they package certain components. For example 2512 resistors are usually in 12mm tape with a 4mm s
