I have a pcb with 750 plated through holes that get Holtite sockets inserted into them. I have a method of pressing in 10 sockets at a time. However, when we are done, the board has bad warpage on the X and Y axis. Does anyone out there have any t

If you are talking about Pin In Hole Reflow that is not true, I hope it was not my friends at Speedline that told you that. Stencil printing of paste for through hole reflow can be done. If you get all the parameters right it can give you joints lik
