PURPOSE: To prevent the occurrence of dispersion in the electrical connection and mechanical strength of secondary soldering by partitioning the inside of each cut-out section formed in the connection member for a soldering purpose into a primary soldering area and a secondary soldering area. CONSTITUTION: Since the connection member 1 is integrally formed out of synthetic thermal plastic resin, four cut-out sections 11 for soldering are formed at both peripheral sections of it in the vertical direction. There exists each cut-out section 21 at a position corresponding to a position forming each cut-out section 11a, and each cut-out section 11b is in a position which coincide with the connection terminal of the circuit pattern of a mother board. A board 2 is rested on the upper surface of the connection member 1, let each cut-out section 21 coincide with each cut-out section 11, let molten solder flow into each cut-out section 21 and each cut-out section 11a, and primary soldering is thereby carried out. Molten solder is prevented from flowing down by partitioning sections 13. By this constitution, electrical continuity is produced between the connection terminal of the board 2 and each cut-out section 11. The member 1 and the member 2 are then rested on the specified position of the circuit pattern, let molten solder 5a flow into each cut-out section 11b, and secondary soldering is thereby carried out. By this constitution, the board 2 is disposed at the specified position of the board 4. |
