Impedance controlled flexible circuits with fold-over shields

摘要: An improved flexible circuit assembly arranged in stripline cable or microstrip configuration with shielding and also being designed a predetermined characteristic impedance. The printed circuits function as cables, employ spacers on either side of the traces so to provide ground planes at dimensional spacing from comprising pattern. arrangement present invention further comprises placing two three individual conductor panels common substrate, accommodate folding panels, one over other, form multi-layer sandwich. Elongated slots are formed along fold lines improve integrity assembly, reduce buckling.
