Method for making a mold for casting open tunnels in plated wire mats

Abstract

Abstract A series of processes are described for making mats to accommodate plated wire memory conductors. Certain of these mats also include interstitial conductors. Outer layers of metal are etched to form word-straps. These word-straps are orthogonal to the tunnels in the mats, which tunnels accommodate the plated wires. Interstitial conductors used, are generally connected to a common point. In order to provide ready access to these tunnels or channels for easy insertion of the plated wires therein, molds are made by either of two special processes, which molds have cavities therein for retaining resin to be molded into walls forming the aforesaid tunnels. The molds provided results in both instances when used in a molding machine and/or in a press, in the final product, wherein the tunnels are blocked off at either end by the plastic material which is also used to form the top and bottom of tunnels. This is done in order to prevent accumulations within the tunnels of undesired matter and thereby prevent blocking of the tunnels and prevent inhibiting the insertion of the plated wires. Therefore, by cutting off an end strip of the plastic material covering the tunnel entrances at both ends after completing of molding or forming operations, the tunnels thus provided are free and clear of undesired foreign matter.
