Is it safe to let Au80Sn20 reflow twice? What I am saying is, for example, die attach using Au80Sn20, followed by lid seal using same Au80Sn20 solder, will it create any problem on the die which was first attached using same soldering material? My

"Although some lead-free pastes performed adequately and newer pastes work better than earlier formulations, this detailed experiment confirmed that tin/lead solder pastes wet back to PCB pads better than lead-free solder pastes. Therefore, a more ac

A common bottomside heater configuration is IR-Convection-Convection. One of the big advantages of the IR zone is its ability to allow the flux carrier to spread and dry slowly before the board reaches the convections zones, which can blow wet flux c

Frank-In addition (Dave gave some good scoop) we use a Pyrex Glass board to run through the wave. This is useful as you can see through the board .....you can watch the flux coverage, preheat, and Wave (be it Chip, lamda, or??) as it goes through the

There are several types of lasers to do laser soldering. Panasonic also has a high intensity light that can solder as well. I've tried em' all and two over whelming things stand out when it comes to this type of soldering. #1 is preheat. It seems

Yes, kind of - I had a look through my notes from a while back where we did a lot of work on bending strenght but the only original source I could find was reference to a paper drawn up in 1979 "Increase Terminal to Pad-Peel Strength with a Standard

Some requirements to consider are: * Humidity and temperature controlled according to J-STD-001 * Electro-static discharge (ESD) control program according to ANSI/ESD-S-20.20. * Soldering technicians are trained and certified according to J-STD-0
