IPC SM 782 has some info on wave solder pad geometries. We usually like .03" spacing to any uncommon conductors. I would assume that you are seeing shorts between components and vias or adjacent parts? Russ

Hi, Our local suppliers keep running out of passives, and it's becoming annoying. Does anyone know of any large component suppliers who sell passives, and often keep stock? We would like to find large US or overseas passive component suppliers for
