Hussman, I'm curious about the same thing. No offense to some of the people here, but this forum's getting frustrating in terms of the lack of expertise. Too many rookies from foreign countries new to SMT, some of them asking really dumb question

Hi, good day to all. This is my 1st question post in this forum. Hope able to share some knowledge here. As we know QFP area like 0.4mm pitch was a very critical area to control especially those PCB using silkscreen printing process manufactured. Onc

Welcome Jimmy Let's mince words to help focus on the issues. When you say "QFP area solder paste shifted," do you mean: * Paste printed on land pattern perfectly, but moves after printing. * Paste printed off the land pattern, even though the stenci

Another thing to make sure of and the vision calibration system will fail if this is out of range: Use a magnet foot stand micrometer and measure the spindle run outs. First remove the nozzles and nozzle adapters, then put the adjustable tip (I dont

Replacing Screen Printer with a dispensing system? If you have large complex PCBs you will lose a bit of time to say the least. That being said, we have had great success with an I&J Fisnar 'bot with positive displacement (auger) valve for dispensi

Hussman, I don't understand the last sentence of yours "but far from where this thread was going". What do you mean with that? I was just trying to give "Novaman" some infos. The fine old equipment You use from the old -20:s or so, is probably just a

Hussman, I'm sorry that I was a little bit tired and on top of that not so sensitive to your humour. Not so easy to understand everything for us Swedish guys. We have normally a great sense of humour over here and almost daily we have a big laughs a
