摘要：Component masks (19) are described for preserving unoccupied holes (17) in a

printed circuit board (12) when such board is subjected to wave soldering. Each mask (19)

is a body of high temperature resistant plastic including a support block (26) from which a

plurality of parallel pins (27) protrude for reception into the printed circuit board lead-

holes (17) to be preserved. The pins (27) are spaced from one another by distances equal

to the distances between lead-holes (17) on a printed circuit board (12), and component

masks (19) are provided respectively having a single row and a double row of such pins

(27). Each pin (27) tapers slightly away from the support, and is connected to its

associated support (26) by a conically shaped transition body (31). Each transition body

(31) is dimensioned to rest on the printed circuit board (12) about the lead-hole (17) in

which the associated pin (27) is inserted to space the support (26) away from the printed

circuit board (12). The pins (27) are dimensioned and configured to enable the lead-holes

(17) to be preserved during mass soldering of the printed circuit board (12), while at the

same time allowing their interior walls to be wetted with solder (29), without the pins

being wetted or conducting away undue amounts of heat.
