Check out ERSA's Ecoselect 350. You can have 2 solder pots in the machine. 1 for SN/PB and 1 for Lead Free. It's a little more than $ than the others, but its a production machine! Not a toy.

What is this? I thought 63sn 37pb was the norm. What is with the 2 at the end? Anyone know?

As far as I know, they rarely do it with Pb-bassed solders. Pb-free may contain Cu or Ni (to improve test performance) Vlad

Actually it's not rare. I use several pastes from various manufacturers that add 2% silver in their leaded pastes. I would bet it's 2% silver.

Isn't that the non-eutectic one that provides the pasty phase range that people use to clobber their tombstoning problems?

The 2 % is Ag.It is added to prevent leaching silver from the end caps of components.This alloy like 63/37 is eutectic and has a reflow temp of 179�C whereas 63/37 is 183�C.

Some great legal language here, Dave. Guess some people don't like their knowledge being shared. Probably shouldn't publish it to the interwebs if that's the case.

We used a similar part and adjusted the routing so that the front edge of the connector was supported and therefore keeping the connector flat and it not being able to tip forward. I don't know if this is something that you can do with your board?

We are experiencing 'lifting' on one or more sides of a QFP. Poor lead co-planarity has been ruled out by independent tests. Please tell me which of the two remaining failure modes is the most probrable? 1. Expansion of gases in vias underneath devi
