Abstract
Improved edge terminals for electronic circuit modules such as single- or multi-chip modules and hybrid circuits, and methods of making the edge terminals are disclosed. The improved edge terminals are formed on the edges of the modules, where they do not take up appreciable surface area from the module, and are formed of heat resisting metal and are of larger size as compared to conventional surface terminal pads which simplifies making connections to the module. In one embodiment, ends of pins are inserted in holes in a substrate along lines which will be the edges of the finished modules. After encapsulating in epoxy, the substrate is cut along the lines to bisect the pins, leaving the halves of the pins as embedded terminals flush with the edge of the module. In another embodiment, terminals are formed by attaching the terminal pieces to pads on the substrate, either in the form of widened zones in a grid structure, or an array of terminal plates. The grid or plates are cut through after encapsulation, bisecting the terminals to form the embedded terminals flush with the edge of the module.
