Title: Adapter arrangement for electrically testing printed circuit boards
Inventor: OTT ALBERT
IPC: G01R31/28
Filed: 1997-12-23
Granted: 1999-08-11
Abstract: An adapter arrangement for electrically testing printed circuit boards consists of two probe adapters with a uniform grid separation of the probes, (9, 9') and two translator foils (6, 6') on whose sides facing the probe adapters there are contact areas (8) with the pitch of the probe adapter. On the sides facing the printed circuit board (2) the arrangement of the contact areas (5) and the contact points (4) located thereon is the same as the grid on the printed circuit board under test. Between the translator foils a vacuum is generated with the help of rubber seals (13), a through hole (14), a valve (15) and a suction hose (16). This vacuum creates a rigid package which permits good contact with the probes on both sides. The inserted support layers (11), which can be conventional printed circuit boards, prevent the translator foils from buckling. The various types of extremely complex printed circuit board can be electrically tested rapidly and cheaply using this arrangement. The arrangement can be employed on both double-sides and one-sided electrical test installations.

Title: Method for manufacturing resin-molded semiconductor device
Inventor: OIDA SHIGEJI
IPC: H01L23/50
Filed: 1998-06-20
Granted: 2000-08-21
Abstract: The sealing step of the resin-molded semiconductor using the sealing sheet has a problem that the sheet itself may form spare crinkle due to heat shrinkage, or form deep trench at the interior lead frame side to form the external electrode. Thus, the area of the seal resin is decreased and the encapsulation intensity of interior lead is reduced. The conductive line frame of the semiconductor device 2 is mounted on the lower mold 12b of the molding device 12. The sealing sheet 6 of the bottom side of the inner conductive portion 1 is pressed in the direction of the molding device. In the condition when the sealing resin 7 proceeds the seal, the vacuum suction device 13 is formed in the inner portion of the lower mold 12b. The sealing sheet 6 is maintained uniformly by vacuum suction to avoid the sealing sheet 6 forming spare crinkle caused by heat shrinkage during the resin sealing process, and thus the resin portion in semiconductor device formed by resin can be flattened.
