Solderability improvements for drag soldered PWBs
Abstract
The causes of solderability problems on drag soldered printed wiring boards (PWBs) were investigated. Excessive removal of tin-lead from the PWB surface was found to be the major cause. A solder leveling method was incorporated to control the consistency of the tin-lead removal process.
