METHOD OF FORMING DISCRETE SOLDER PORTIONS ON RESPECTIVE CONTACT PADS OF A PRINTED CIRCUIT BOARD

摘要

The invention provides for a method of forming discrete solder portions (16) on respective contact pads (10) whereby a strip of solder paste (12) is formed over a plurality of said pads (10). The strip (12) is formed with portions of reduced width (14) which are located over the spaces (22) between adjacent pads (10). The paste is melted and the surface tension at the portions of reduced width (14) causes the movement of solder towards the pads (10) and the separation of the strip (12) into discrete solder portions (16).
