Abstract

Memory cores 10 can be wired into matrices with flexible printed circuits 12 snapped into position over the cores. Such action is effected by mechanical pressure exerted on the printed circuits. Cores 10 are loaded into matrix block 16 and held there while the printed circuit 12 with slots at the desired core locations is positioned over the cores. Then matrix press block 14 is lowered on top of printed circuit 12 and uniformly pushes it down forcing the cores 10 through the cut slots. As the cores 10 emerge through the top of the printed circuit 12, tabs formed by the cutting of the slots, spring back into position through the core apertures and with the help of the mating matrix blocks 14 and 16 are pressed into position against one another. The core array is then removed from matrix block 16 and inserted in an oven.

Snap In Printed Circuit Wiring

Memory cores 10 can be wired into matrices with flexible printed circuits 12 snapped into position over the cores. Such action is effected by mechanical pressure exerted on the printed circuits. Cores 10 are loaded into matrix block 16 and held there while the printed circuit 12 with slots at the desired core locations is positioned over the cores. Then matrix press block 14 is lowered on top of printed circuit 12 and uniformly pushes it down forcing the cores 10 through the cut slots. As the cores 10 emerge through the top of the printed circuit 12, tabs formed by the cutting of the slots, spring back into position through the core apertures and with the help of the mating matrix blocks 14 and 16 are pressed into position against one another. The core array is then removed from matrix block 16 and inserted in an oven. The oven temperature is elevated to a point where solder on the printed circuit lines melts to bridge the slots in the printed circuits to thus complete the circuits through cores 10.
