| We are installing a new reflow oven and I have been told that we do not need to vent the exhaust out through the roof since we have a false ceiling. All that is required is to vent above the false ceiling and that the air exchange is great enough t

Here's part of what I could read: "We evaluated the influence of Lift-off (Fillet-lifting) and the influence of thermal fatigue, in this case on combination between various terminal platings of electronic components and Pb-free solder, Sn-37Pb solde

| | Some of my friends ask me if sombody use lead free solder ball on BGA, espically PBGA packages. I wonder if 96.5Sn/3.5Ag (m.p .221 oC) or 58Bi/42Sn (m.p. 138 oC) would be suitable candidates? Do you have any experience on this subject? | | | | K

First, it depends on the alloy composition of the solder. As you might know, eutectic Sn/Pb solder has the lowest melting point among available conventional solder systems. (except those based on Sn-In and Sn-Bi systems.) For example, 63Sn/37Pb - 183

The Technical Services Group at Alpha Metals has spent a fair amount of time looking at wave soldered Pb-free connections. We too have observed fillet tearing, fillet lifting, and pad lifting. I have concluded that without major changes in the mate

| I am attemping to gather as much information on the issues with and progress in solutions for manufacturing Pb free products in response to European initiatives (WEEE). I am intereested in component issues with As Made lead terminations (no Sn/Pb)
