Abstract
Abstract The invention is directed to an etched wiring (spider) for integrated circuits having a metallic frame for electrodeposition and shorting purposes proceeding all around at the periphery and connecting the wiring at several points. When separating a plurality of circuits lying side-by-side after the electrodeposition, an entire strip of the carrier material previously had to be discarded in order to enable the short-free separation of the etched wirings. In order to avoid this waste, the invention provides that the leads to the junctions of the frame with the wiring of neighboring circuits be fashioned meander-like.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
107 words
A plurality of etched wiring for film-mounted integrated circuits, comprising: metallized strips which proceed substantially parallel around two opposite sides of each of said wirings mounted on a substance and which electrically connect to each of said wirings at a plurality of junctions; and leads for supplying an electroplating voltage from the metallized strips which are substantially perpendicular to said metallized strips interconnecting the junctions of neighboring wirings at a line of seperation wherein the leads are fashioned meander-like in substantially opposing U-shaped configurations about said line seperation such that adjacent etched wirings can be seperated from each other with one cut at said line of seperation.
