US 5,434,749 A · Hybrid printed circuit board

Abstract

This invention concerns a hybrid printed circuit board which permits easy and reliable connection between small-current circuit conductors and large-current circuit conductors. The hybrid printed circuit board of this invention comprises: an insulating substrate of synthetic resin having fixing bosses erected thereon; a flexible printed circuit sheet having small-current circuit conductors; and busbars as large-current circuit conductors; wherein the flexible printed circuit sheet is stacked and arranged on the insulating substrate so that the fixing bosses erected on the insulating substrate pass through and above the flexible printed circuit sheet, the busbars as large-current circuit conductors are put in contact with the small-current circuit conductors, and the fixing bosses are heated and deformed to fix the busbars in place.

Dependent claims

A hybrid printed circuit board comprising:

an insulating substrate of synthetic resin having fixing bosses erected thereon;
a flexible printed circuit sheet having first circuit conductors for conducting a current;
and
busbars as second circuit conductors for conducting a current larger than the current of said first conductors;
wherein said hybrid printed circuit board is constructed such that said flexible printed circuit sheet is stacked and arranged on the insulating substrate so that said fixing bosses erected on the insulating substrate pass through and above said flexible printed circuit sheet, said busbars are put in contact with the first circuit conductors, and said fixing bosses are heated and deformed to fix the busbars in place.
