摘要： PURPOSE:To greatly shorten the testing time for a molded semiconductor device, by forming simultaneously the reinforcement of the resin material among the resin parts molded via leads. CONSTITUTION:When forming a resin mold type transistor 3 integrated into a frame 2 via leads 1, the reinforcement parts 7 or 8 of the resin material are simultaneously formed on the back surface of the resin materials 4a-4c or the head part in an integral body. In this constitution, even when the lead frame 5 for reinforcement is removed, collector leads 1a and base leads 1c are separated from the frame 2, and individual devices are supported only by emitter leads 1b, the position is stabilized against the external force because of the presence of reinforcement parts 7, 8. Therefore, a test is performed by contacting probes 6 respectively on leads 1a, 1b and the reinforcement part 7 or 8 is removed after the test. In this constitution, a test can be performed more rapid than the case using a parts feeder.

摘要： PURPOSE:To permit the easy and exact connection between coil terminal and external lead wire by fitting a conductor with plural holes to which the first and second conductors are to be connected at an insulating base plate with plural projections by combining each projection with each hole. CONSTITUTION:The insulating base plate 11 is provided with the plural projections 15 and also the conductor 12 to which the first and second conductors are to be connected is provided with plural holes 16 at positions corresponding to the projections 15. Of the plural holes 16 of the conductors 12, at least one hole is of smaller diameter than the others and designed so as to fasten the conductor 12 to the insulating base plate 11 by means of supersonic caulking or heat welding after insertion by pressure of the projection 15. Thus, the connection between the coil terminal 5 and the external lead wire 7 can be easily and exactly made.

摘要： PURPOSE:To greatly shorten the testing time for a resin sealed semiconductor device, by providing joints for reinforcement connecting leads and a frame. CONSTITUTION:Joints for reinforcement 9 or 10 are provided connecting emitter leads 1b and a frame 2 and elements are sealed by resin materials 4a-4e. Thereafter, even when a frame 5 is removed, and collector leads 1a and base leads 1c are separated from the frame 2, the position of the resin material 4, i.e. each semiconductor device is stabilized by the joints for reinforcement 9 or 10. After the characteristic test by contacting probes 6 on leads 1a, 1c, the reinforcement joints 9 or 10 are removed. In this method, a testing time can be shortened greater than the case using a parts feeder.
