Abstract: PURPOSE:To easily join the pins of an IC package with electrodes so that electrical contact can be secured between them by using a frame for plating having holes of diameters smaller than the front-end diameters of the pins at positions corresponding to the pins and a plurality of pin holding sections composed of slits around the holes. CONSTITUTION:The pins 2 of an IC package 1 are joined with a frame 3 for plating made of a conductive material by inserting the front end sections of the pins 2 into the holes of the frame 3 and expanding and deforming pin holding sections 10 composed of slits or notches formed around the holes of the frame 3 by means of the front end sections of the pins 2. Then, after connecting the pins 2 with a conductive pattern 4 by plating through the frame 3, the frame 3 is removed and, at the same time, the pins 2 are cut off at positions on the package 1 main body side from the contacting sections of the pins 2 with the holding sections 10. Therefore, the pins 2 can be easily joined with the frame 3 which is used as electrodes and the need of welding work, etc., can be eliminated.

Abstract: PURPOSE:To improve the test efficiency and to shorten the test time by sharing a part of the function test with a DMAC (direct memory access controller). CONSTITUTION:A test device gives the high-speed slave writing designation to a DMAC 11 and at the same time supplies the data A1, A2... for writing and the output expected value data D1, D2... to the DMAC 11. Thus the DMAC 11 writes temporarily the data A1, A2... into a memory unit STmem and then reads them out. Then the DMAC 11 compares the data D1, D2... with the data G1, G2... and sends the information PCL showing the result of this comparison back to the test device. In such a way, the DMAC 11 shares the partial test functions like the reading and comparing actions and therefore the test device can be intent on writing the data to the DMAC 11. The DMAC 11 performs the partial test functions in parallel to said writing action of data. Thus the test time is shortened.
