Barry, If you are looking to set up a documented process with set parameters you might think about performing a DOE based on the parameters you can control or change. With any measurement device you should be able to log the info gathered so you ca

We have a PARMI SigmaX SPI (Solder Paste Inspection) machine, right now I'm trying to understand about parameters of the machine. I know minimus, Maximus, and warning values need to be defined. Height value understands that can be defined by the thic

Sorry, what I meant was that they don't provide a duration for that liquidus + 20�C value that I've seen bantered about here and on TechNet. They only provide the same stock time above liquidus of 30-90 that they've always used. I'd like to see refe

Depends on your board? What finish? Solder mask between all pads? What pitch is the part? Will it machine placed? Don't forget proper profiling as well. 1:1 with machine placement should yield no issues.
