Abstract

A process is provided for embedding cores in a polymeric material. As shown in A, copper strip 2 bears insulation 6 on one side. Next as shown in B, a layer of mercury 3 is deposited over copper 2. Following this, as in C, individual cores 4 are selectively placed above mercury 3 which is superimposed over copper 2. Then the entire setup is processed such that electrophoretically deposited material 5 separates the cores as in D. Lastly, the copper-mercury layer is peeled from the core matrix leaving a matrix of alternate cores and layers of polymeric material as in E.
