We've all been soldering Pb free parts for a couple decades. All your surface mount capacitors have probably had a Sn finish for years. Whenever one of our parts with a SnPb finish converts for Pb free we have the manufacturing site do a small buil

Hi, I think the comment about the board height is because the MYDATA checks the board height each time it loads a tool so this is eliminated from being an issue because the machine knows the PCB height. I don't think it's so much what height the PCB

We do the following things: 1.) RoHS PCB:s is marked with a code. This is to identify that the PCB:s itself are RoHS compliant. 2.) If it is a true RoHS PCBA; we put a printed label with a green "texture" on the PCBA. 3.) If it is a mixed PB free/PB;

There have been times when we could have done with having a Ken or 2; He may not always agree with everyone but he has demonstrated a very good process knowledge over all the time I've been using SMT net. Also I've never read one of his posts that w
