We consider "IR-reflow soldering profile" to be the supplier's recommended reflow thermal profile that a component temination 'sees' for proper soldering, regardless of the method used to reach that temperature. When you say, "We have a lot of defec

Yes, this scenario is fine. However, BGAs are a different story since the ball is the bulk of the solder joint. In this case, you MUST run a "hybrid profile". Look it up in the fine SMTNet archives (keyword: hybrid profile). I have "been there an

You are making sense. And no you can't go from centroid data to a program at the machine automatically. You can type in the numbers if you want but the machine won't turn centroid into a placement program. Don't you have PanaPro? I thought there w

I hope this doesn't add any confusion. I save my data as a .csv file and bring that into Cad2cad. This is how I was shown to do it by Assembleon. To use .csv you have to set your file format on the format cad file tab(during import to Cad2cad) to Cha

What the other user was talking about is correct, converting it from gerber to machine cad. It is hard explaining programming SMT to a new user unless shown by another experience operator. I am also getting a topaz x pretty soon and I'll try to hel

Q1.Does anyone know a way to verify the amount of OSP coating on a board? A1. There is no specification. Thickness is difficult to measure. Thickness is product related. There are at least six major suppliers. Years ago, here on SMTnet, J Medernach s
