Solder interconnects for selective line coupling

摘要

A structure and method for selectively forming interconnections (31) between the interconnect lines (20) of a printed circuit board (100). At the same time solder is deposited through a solder application mask to bond the modules to the board, solder is also deposited on pad interconnect structures (30) between the interconnect lines. Thus, line interconnections can be formed at minimal additional cost, reducing the number of different boards needed to mount different sets of modules or alternate component or circuit configurations. In a preferred embodiment, the pads (30) comprise an arcuate member and an elongated member extending within the arc described by the arcuate member. By optimizing the spacing between the members, the total area of the members, and the volume of the solder, a highly reliable solder fillet interconnection can be formed.
