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

hello evryone. I am rleatively new to smt production. Though we have been successfully running pcb assy's and getting very good solder quality we are trying to get some proccess control parameters set up for our printing process. We have a semiauto s

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.

Adhesive printing parameters

dots of minimal height. So, use a lower viscosity adhesive. * Higher standoff components => larger (and taller) dots. So, use a high viscosity [typically, also high yield point] adhesive.

I am printing on DEKs and using simulara paramateres as for a solder it works really fine. In general going faster gives you more paste/glue. Less pressure gives you more paste/glue again. All the rest depends on your current board. Regards, Emil
