主权项

1. A printed circuit board, comprising:
a base substrate including a first outer surface and a second outer surface defining a thickness of the base substrate; at least one through-hole in the base substrate, the through-hole extending to and open to the second outer surface; a connection tab extending through the through-hole; an electrical element on the base substrate and adjacent to the through-hole; and at least one groove portion including a bottom surface in the base substrate, extending from the bottom surface to the first outer surface to define a depth, open to the first outer surface, and adjacent to the electrical element, the electrical element being on the bottom surface, the groove portion being continuous along an entire circumference of the through-hole, and the depth of the at least one groove being less than the thickness of the base substrate.
