Abstract:
1. An electrical apparatus comprising: a first printed circuit board including an insulating substrate having first and second opposing two major surfaces, with an electrically conductive film formed inside said insulating substrate; an electrical component external to said first printed circuit board, said electrical component having a rigid connector which extends through said first and second two opposing major surfaces and is connected to said conductive film; and a second printed circuit board mounted at a location on a first one of said major surfaces spaced from a location on said first major surface where said electrical component is connected to said conductive film, said second printed circuit board being mounted to contact with and be perpendicular to said first major surface; wherein a flexible portion is formed in said first printed circuit board at a location between said location where said electrical component is connected to said conductive film and said location where said second printed circuit board is mounted on said first printed circuit board; wherein said flexible portion is formed by removing portions of said insulating substrate forming said flexible portion from said first and second major surfaces; and wherein said flexible portion has said conductive film disposed inside said flexible portion.
