Solder thickness
WebThe thickness of solder you should use will depend on the specific application you are using it for. For most general soldering applications, a tin-lead solder with 60/40 or 63/37 alloys … WebThe maximum thickness for solder masks on finished copper parts of up to 35 micrometers is 40 micrometers. If the copper is thicker, the solder mask can be as thick as 80 micrometers. Meet minimum annular ring requirements if the solder resist encroaches on lands. Permit solder resist only when plated through holes not intended for solder fill.
