Ya Russ is right for Ti Parts they tend to use more pelladium, which requires a bit more heat average temp increase is about 10 degrees C. from 225-235. As far as optimum solder joint I look for fillets on all sides of leads. The back of the lead is

Wipe away all you want, if you look at your board under magnification you'll still see some paste stuck on your board. I guess it depends on what you consider clean to be. Most alcohol wipes will work fine, but only a form of washing will truly get

Dback, Some questions for you: 1. Are you using the red light configuration for better contrast on the 0402 parts? 2. Is your system fitted with both low and High Magnification cameras? Have you spoken with the guys at YESTech? Their phone support i

We can speak from experience, the Ersascope needs only 1.5mm to see along side a device and is the only system that looks low enough, the cheaper systems may be fine for normal packages but forget it for csp's, micro BGA's Also its the only system th
