Abstract: A method for producing an electric contact extending from a copper foil, comprises steps of fixing a cover lay having a hole of a diameter smaller than that of the copper foil of a predetermined size to the copper foil, and plating the hole of the cover lay so as to reach the upper surface of the cover lay as a first step; installing a dry film having a hole of a diameter smaller than that of the hole of the cover lay onto the cover lay, and plating the hole of the dry film so as to reach the upper surface of the dry film as a second step; and after removal of the dry film, as a third step further plating the plate layers obtained in the first and second steps. The electric contacts produced by the method have a predetermined height which is as high as possible and uniform without causing any defective connection between them. In a method for producing an electrical connector, diameters of the holes of the dry film in plating are changed depending upon positions of the electric contacts.

Abstract: A method for connecting connection members to through-holes of a board by soldering is disclosed. The board is press holded on its one side by a jig, and paste solder or solder in paste form is forced to flow into each of the through-holes of the board from the opposite side by a paste solder printing method using a printing mask. The printing mask is then removed under the condition of the paste solder being filled in the through-holes. After the connection members have been inserted in the through-holes of the board or have been urged against the board on the opposite side, the connection members are further connected to the board by reflow soldering, while the board is still continuously restrained or press holded on the one side by the jig. In this manner, it become possible to form any desired shapes of a plurality of solder connection portions connected to the board on the one side. As a result, the solder connection portions can be formed to be a predetermined height to prevent them from interfering deformation of contacts to provide a constant contact pressure of the contacts, thereby eliminating defective or failed connection.

Abstract: A surface mounting method for mounting an electronic part having a great number of contacts onto a circuit board. A jig provided with dummy contacts is prepared whose size, number and arrangement are substantially the same as those of contacts of an electronic part to be mounted on a circuit board. The dummy contacts of the jig are then fitted with mating contacts which are to be fitted with the contacts of the electronic part. Thereafter, the jig provided with the dummy contacts fitted with the mating contacts is mounted onto the circuit board at a predetermined position thereon. The mating contacts are then mounted and fixed onto the circuit board. The jig is then removed from the circuit board. The contacts of the electronic part are then fitted with the mating contacts fixed to the circuit board. As an alternative, double ended socket contact members are prepared, each having socket contacts on both ends. Pin contacts of a circuit board are fitted in the socket contacts of the double ended socket contact members on their one ends and then pin contacts of an electronic part are fitted in the socket contacts of the members on their other ends.
