Abstract
Multilayer printed circuits with four to six layers are replaced by one double-face circuit with metallized holes of equivalent density. The Swiss company ERCI represented by Sifrem has just set up for fabrication of printed circuits having 200-microns-wide tracks four of which fit between the pins of the DIL case.
