We assume the three leads are lined-up perpendicular to the wave. Without taking corrective action, we know this: * 50 thou pitch will bridge * DIP do not bridge As a corrective action that doesn't invovle a respin of the board, decrease the solderm

Heck, now I look up and see this is SMTdotNET. Do I get banned for asking a TH question? So here's my first real TH issue after living so long in the SMT world. We are having a sudden issue in what has been a stable process for quite some time. I

There are several things that can be done. Shortening the lead length should eliminate bridging between lead. We had done a project several years ago where the customer had shortened the leads to almost flush to the board, preventing any chance of
