A two-sided printed circuit board, comprising:
- a base having a first surface, and a second surface substantially parallel to the first surface, the base having a plurality of through-holes;
- a first conductive layer provided on the first surface of the base;
- a second conductive layer provided on the second surface of the base;
- and
- a conductive particle provided in each of the through-holes in a pressurized state for electrically connecting the first conductive layer and the second conductive layer.
A multi-layered printed circuit board, comprising:
- two bases provided in a laminated state;
- and
- a conductive layer provided between the two bases, wherein
- the bases each include a plurality of through-holes,
- the through-holes each have a conductive particle provided therein in a pressurized state, and
- the conductive particle electrically connects the conductive layer and another conductive layer provided on at least one of the two bases.
