Abstract

PURPOSE: To improve the BDS characteristic with respect to bend strain through insulation in combination of a glass lined hybrid mika preplg, a lined frake mika preplg and a polyimide film preplg.
CONSTITUTION: When a glass-lined hybrid mika preplg is expressed by U, a glass- lined frake mika preplg M, a polyimide film preplg. In the insulation arrangement, U is infollibly interposed between M and K without continuously winding M and K. This can not only improve BDS but also affored a better coil with a stable electric characteristics because the standard deviation can be reduced to one-third that shown by the example for comparison.
