Concave cup printed circuit board for light emitting diode and method for producing the same

摘要

A concave cup printed circuit board includes a substrate and a cup forming plate. The substrate has an electrical circuitry and at least one contact pad connected to the circuitry. The cup forming plate has at least one through-hole and at least one cup-shaped wall confining the through-hole. The cup forming plate overlies and is connected to the substrate such that the through-hole is disposed over the contact pad. The cup forming plate and the substrate are fabricated separately. The through-hole is formed in the cup forming plate before the cup forming plate is connected to the substrate.
