Has there been a definite date for the total move over to lead free? Will it be 2004 or 2008. Also is there a direct replacement for leaded solder, I have read various articles on numerous alloys suggested for the switch, such as bismuth, tin, copper

Thanks, Evtimov. In terms of mechanical drop performance, can we conclude that the higher Ag alloy will have poorer drop shock performance relatively compare to those with lower Ag? The Ag3Sn is a good IMC for welding strength?

Hi everybody: I really need your expertise on this one. I was told that the flux 270WR from AIM is either No-clean or WS soluble depending on your needs. I read the TDS and it looks like it is....but..... Is there anybody out there using this or s

As Emil says, it's 100% the glue! Your paste is not designed to hold parts on at wave solder. Reflow is MUCH hotter than glue, so I doubt you're not adequately heat-curing it. Possibly, the glue cure is "too hot" and maybe making the material brit

EricR: There's substantial information about the properties of solder alloys on the web. Here's an example of something that I clipped from one site Alloy ||Solidus (°C)||Liquidus (C°) ||Tensile Strength (psi / MPa) Sn42 Bi58||-E-||138||8000 / 55.2

Hey all! As background, I recently purchased a full SMT line for my company. We have a DEK 265, an assembleon opal xii, and a Heller 1500. Currently our jobs are leaded, and the heller is working perfectly. An upcoming job that we are potentially g
