Just a thought... At that scale you might try to print paste on the devices and reflow to make bumps. That combined with your paste on the PWB might be sufficient. 'hege

I think the critical item is that you are soldering in a reduced oxy environment, lowering the rate of ongoing oxidation. Heat accelerates oxidation, lack of oxygen (of course) slows it down. The 10 Nitrogen soldering "myths" seem to be more like "

The ASG (Tyco) MEP (Manual Electric Press) or the AEP (Automatic Electric Press) are both excellent machines, we have used them successfully on all types of press fit connectors. Give Dante Parenti a call and he can help you out. (215) 784 4530 Or g

I've had this problem before. Typically happens when the Lithium Battery dies and the machine loses the program. Usually you can pull the displays out and ship them to Simplematic. They can reload the program for you. Roughly $2500 bucks I think. Cal

Ok, I can't resist. I agree that a rep should be allowed to contribute if he/she identifies themselves. There will always be a conflict between technology/information and sales. Here's another example. If you are reading say, Circuits Assembly or SMT

Yep, we did it just the way you described, I think. What we did NOT do was a block conversion. We just built it a board at a time, to see if things were accurate when we first programmed it. They weren't, so we did away with the block fids, adjusted

RDR, If you buy a meter you have to send it in once a year to get calibrated at a certified calibration lab. Can be expensive. If you use one that is not certified, and something happens your company will be legally responsible. Major risk. Go
