PURPOSE: A semiconductor package is provided to reduce the damage of the solder ball caused by the external shock. CONSTITUTION: A semiconductor package includes substrates(110,120) and a connection terminal(130). The substrate has socket portions. The connection terminals have the solder ball and the supporting part. The solder ball is located on the top of the substrate. The supporting part supports the solder ball by being inserted into the socket portion and extended from the solder ball. The socket portion includes a depression or a hole. The depression is defined by the side wall and the bottom part. The hole passes through the substrate. The substrate is the multilayer board in which the insulating layer and the inner wire are repeated or the printed circuit board which has the inner wire.
Abstract:
A resonator/filter (100) adapted for direct surface mounting to the surface of a printed circuit board. The resonator/filter comprises a block of dielectric material (110) including at least one resonator through-hole (101-104) extending therethrough and respective top (112), bottom (113) and side surfaces (114-117) defining respective regions of dielectric material covered with conductive material. The top block surface defines at least a first conductive region. A second conductive region on the bottom surface of the block defines an input/output contact which allows the filter to be mounted on the board with the bottom filter surface seated thereon, thus providing a direct ground contact between the board and the resonator through-hole for improved attenuation performance particularly at higher frequencies. A plurality of transmission line embodiments (131, 156) electrically interconnect the first and second conductive regions.
