Abstract

PURPOSE:To achieve an effetive fabrication of a circuit block by performing the following procedures: A printed wiring board is fabricated by bending the lead end of a lead frame, parts are installed by feeding them intermittently to the prescribed position, and after they are soldered, the lead is cut and bent at the frame section. CONSTITUTION:A calking section 4 is formed by bending upward the end of the lead terminal of the lead frame and it is driven by engaging the convexed section of a roller 6 to the groove 5 of a frame 3. The calking section 4 is inserted to the hole 9 of a printed wiring board 8 and a calking is performed. Then a constant feeding is given, a part 10... is installed at the prescribed position and it is fixed by soldering. Lead wire 11 is cut off at the paint near the frame 3 and bent downward 2. Thereby the circuit block is automatically assembled in very cheap cost by these method.
