Abstract

PURPOSE:To position an electric part easily, and to inspect soldering readily by inserting the electric part, which has a truncated cone-shaped body and upper and lower surface sections of which have electrodes, into an opening section having a taper and soldering a circular pad in the periphery of the opening section and the electrodes. CONSTITUTION:An opening section 2 for mounting a part is formed to a tapered shape in a printed board 1, a circular pad 6 is shaped around the opening section 2, the body of an electric part 3 for mounting is also formed to a truncated cone shape, and electrodes 4 are shaped previously onto the top face section and underside section of the body. The electric part 3 is inserted into the opening section 2, dip soldering is conducted twice on the rear and the surface or reflow soldering is performed by using cream solder, and the pad 6 and the electrodes 4 are connected by solder 5. Accordingly, the opening section 2 is formed to a tapered shape, thus distinguishing the polarity of the truncated cone-shaped electric part 3, then easily inserting the electric part into the opening section 2 of the printed board. Inspection after soldering is also facilitated because an automatic inspection device can be used.

This is provided. The body of the electrical component 3 for mounting is also shaped like a truncated cone, and electrodes 4 are formed on its upper and lower surfaces. The length of the body is made slightly larger than the thickness of the printed board 1 so that the electrodes 4 will not protrude slightly from the front and back surfaces of the printed board after mounting. Electrical parts 3
After inserting the pad into the opening 2, the pad 6 and the electrode 4 are connected with the solder 5 by dip soldering twice on the front and back sides, or by reflow soldering using cream solder.
