Example embodiments may be directed to a printed circuit board having an insulating substrate, pads disposed on the surface of the insulating substrate, a solder resist, and a solder moving portion. Leads of a semiconductor package may be mounted on the insulating substrate. The pads to which the leads of the semiconductor package are connected may be disposed on the surface of the insulating substrate. The solder resist layer may cover the insulating substrate, but may also contain openings exposing at least a portion of the pads to which the leads of the semiconductor package are connected. During the process by which each semiconductor lead is connected to a pad, the solder moving portion on the pad may allow an adhesion solder coating each of the leads of the semiconductor package to move towards a shoulder portion of the semiconductor package leads.

A novel heat sink structure for being mounted to a module board to which semiconductor chips are attached and for dissipating or spreading heat generated from the semiconductor chips is disclosed. The heat sink comprises a heat sink base, and a coupling means for coupling the heat sink base to the module board. The coupling means passes through the heat sink base. The coupling means includes integrally formed upper and lower body portions, an orifice formed at least through the lower body portion, and a flanged base formed integral with the lower body portion. The flanged base fixes the coupling means to the heat sink base. The outer dimension of the upper body portion is smaller than the inner dimension of the lower body portion. As a result, many heat sinks can be stacked stably.

A PCB can include an insulating member, a cooling member, and a circuit pattern. The cooling member can be built into the insulating member. The cooling member can have a cooling passageway through which a cooling fluid can flow. The circuit pattern can be formed on the insulating member. Thus, high heat in the circuit pattern can be rapidly dissipated by the cooling fluid flowing through the cooling passageway.

摘要:
A method of testing a substrate may involve photographing a first chip on a first face of the substrate to obtain a first image of the first chip, and photographing a second chip on a second face of the substrate opposite to the first face without reversing the substrate to obtain a second image of the second chip. The normality of the first and the second chips may be determined based on the first and the second images.
