Hi, We are in the way to evaluate different solder pastes, improve our solder paste incoming inspection steps, re-define our stencil requirements and the following questions are open. Two questions, 1- Is anybody using/requiring 1000 Kcps or more

Crystalline flux if it is really clear should not be a problem. We were using Amtech paste before and we have the same results. Sometimes we mistakenly see it as a dry joint because of the reflections from the lighting of our Metcal inspection system

I am trying to optimise the use of our Automatic Optical Inspection Machines. As the data we collect from the machine is mainly of the attribute type (Pass/fail, Defect1, Defect2, etc), what advice can you provide to improve its use as well as using

And why do you want to control the process? To prevent defects, I would think. Actually orginally the way I first saw SPC was to reduce inspection. If you are using SPC for plating thickness, you don't have to measure every piece to be confident the

You are not wrong in monitoring the Product (your really not monitoring the process). This methodology is valuable if your process is unstable (SPC is used to stabilize process). There is value in "real time" inspection of a process's product as lon

Haven't done any studies other than how clean can you get a stencil. I would clean 'em and inspect the apertures and see if you have any residues. If so, I would clean again the amount left would be so miniscule that I don't beleive it would cause
