<p>PURPOSE:To prevent terminals from coming in contact with tie bars by arranging headers, which are installed on a pair of frames, to mount chips face to face and joining said headers with the tie bars intersecting the direction of the projection of the terminals through the terminals projected on the headers. CONSTITUTION:When a first frame 1 and a second frame 2 are arranged to place the headers 11a and 21a thereof face to face, the leads 11c, 12c, 21c, and 22c of the frames 1 and 2 can be arranged on one plane. In this time, the tie bars 13 and 23 of the frames 1 and 2 face each other with the headers 11a and 21a therebetween, therefore, are not in contact with terminals 11b, 12b, 21b, and 22b. After the frames 1 and 2 are thus arranged in the specific positions, molding is performed and the tie bars 13 and 23, bridging pieces 14, 24, and 25, and connection pieces 21d and 22d are cut.</p> |
