发明名称 Spacer, and its manufacturing method
摘要 Provided are a spacer capable of avoiding a poor connection due to the suction of solder when the clearance width between a soldered semiconductor device and a printed circuit board is made constant, and a manufacturing method for the spacer. The spacer includes an electrically insulating base member, and at least one solder guiding terminal. The base member has a bottom face, a top face and at least one side face, of which the bottom face and the top face are out of contact with each other whereas the side face contacts one or both the bottom face and the top face. The solder guiding terminal covers the bottom face partially, the top face partially, and the side face partially or wholly. A solder guiding face as the surface of a portion of the solder guiding terminal covering the side face is not normal to the bottom face.
