circuit multilayer imprimat determined by its width, thickness and length, must be small enough for the current the conductor will carry. It is recommended that the power and force paths be larger than the signal paths. In a multi-layer board, an internal layer may be mostly solid copper to
0.1-0.3 mm with a rigid printed circuit on an FR4 substrate. These printed circuits are used more and more lately, having the advantage of their flexibility. A PCB may have an inscription or imprimat circuit multilayer screen printing that identifies components, test points or identification text. Screen printing does not normally affect the operation of
in ohms and makes it possible to measure the quality of copper tracks. The impedance is an alternating current (AC) characteristic that increases with frequency and becomes critical for printed circuits operating at frequencies above 200 or 300 Mhz.
