are you familiar with UL 796, Printed Wiring Boards i believe they discuss some standards and test procedures regarding conductor material, and solder material but im not sure if UL actually lists solder material by it self.

Any recommendations for a good PIN FRIENDLY PB-Free ROLO solder paste? My process is OSP double-sided reflow with PTH wave soldering.

Hi Doug Nice idea (2 type paste), I will have a trial. We think of glue and tape too, but it involve cost, but we still keep as an option. thanks.
