Abstract
Component masks are described for preserving unoccupied holes in a printed circuit board when such board is subjected to wave soldering. Each mask is a body of plastic resistant to adherence to the solder and capable of withstanding the temperature of solder when the printed circuit board is subjected to wave soldering and includes a supporting block from which a plurality of parallel pins protrude for reception into the printed circuit board lead-holes to be preserved. The pins are spaced from one another by distances equal to the distances between lead-holes on a printed circuit board, and component masks are provided respectively having a single row and a double row of such pins. Each pin is tapered slightly toward its free end, and is connected to its associated supporting block by a conically shaped transition body. Each transition body is dimensioned to rest on the printed circuit board about the lead-hole in which the associated pin is inserted to space the supporting block away from the printed circuit board. The pins are dimensioned and configured to enable the lead-holes to be preserved during mass soldering of the printed circuit board, while at the same time allowing their interior walls to be wetted with solder.
