I don't personally care for a DEK screener. I have used MPM and Deks. We had Deks come into our house and repacked them about a week later and sent them back. But we are a larger house and do lots of changovers. Now on the upside if you are low volum

We use SRT. We still have machines that are over 5 years old and are functioning very well in the BGA, QFP and yes CSP area. The critical part is getting the right Air nozzle for the part size. Also the software has a auto-profile feature that wor
