摘要： PROBLEM TO BE SOLVED: To accurately form a partial plating face at a desired position on the surface of a lead pin. SOLUTION: First, a lead pin 10 is subjected to plating over the entire surface thereof, and a metal film 12 is formed. One end of the plated lead pin 10 is then coated with a gel-like member 14. In this state, a desired plating face part 16 of the lead pin 10 exposed to the outside of the gel-like member 14 is subjected to the action of a metallic film stripping agent 18, in order to strip off the metal film 12 from the plating face part 16. Plating face of the metal film 12 is thereby formed at a desired position on the surface of the lead pin 10, and the material surface 20 thereof is exposed in annular shape between the plating faces. When first, multiplayer plating is carried out, plating surface 20 of an underlying layer is exposed at the desired position of the lead pin 10.

摘要： PROBLEM TO BE SOLVED: To reduce types of terminals through the common application of connecting terminals and facilitate the mounting work on a circuit board by forming a conductive pattern to connect an insulating securing part to a connecting part formed on a board mounting surface on the surface of an insulating body to fix a contact terminal at the insulating securing part. SOLUTION: In a plug connector of a board mounting connector, multiple terminal securing holes 123c are formed in the front face of a plug insulator 313 and a conductive film 313a made of gold or the like is formed on each of their inside wall 123c'. In each of the securing holes 123c, a plug terminal equipped with a plug contact at its one end and an insulator securing part at its other end is so placed as to be corresponding to a mating connector by securing it at the insulating securing part. This terminal can easily be formed by means of a normal press punching technique. In addition, on a recessively stepped surface on a securing hole opening surface 123c" of an insulating body 123, a conductive pattern 313b made of gold or the like is formed and then, the plug terminal and a board connecting electrode 313c formed on a board mounting surface 123b" are connected through the conductive film 313a and a solder bump 313d.
