    摘要: A large scale integrated circuit package and test assembly wherein a chip is mounted on an insulating package substrate, and the package substrate is easily demountably connectable on a circuit test board. An alignment and electrical connector member bridges between the substrate conductors and the printed circuit board conductors. An elastomeric member is aligned over the alignment and electrical connector and compressed by a cover plate to make the electrical connection between the substrate and the printed circuit board. A plurality of such circuit package can be mounted upon a large area test board, and each of the individual circuit packages can be tested during system analysis.

    摘要: There is disclosed a method for producing in thick (0.005 inches) polyimide films or sheets, openings, or windows across each of which an electrical conductor, such as copper or aluminum extends. The windows may be of substantial dimensions typically 0.05 inches by 0.1 inches. The conductor is of substantial thickness of about 0.0008 to 0.001 inches. The method is practiced with a sheet in which holes have been preformed. The sheet is coated with the conductor on both surfaces by being rotated in a stream of vapor of the conductor produced by impinging an electron beam (typically at 10 KV and 300 milliamperes) on a block of the conducting material. As the sheet is rotated in the stream of vapor, the walls of the holes as well as the surface of the sheet are coated with a conductor. Photoresist is then deposited on both coated surfaces of the sheet and in the holes and is exposed under masks and developed so as to expose the conducting coating on each surface in the areas of the windows. The exposed coating is then removed with an acid etchant while the remainder of the surfaces including the coating on the walls of the holes remain protected by the developed photoresist. The polyimide in the areas of the windows is thus exposed. The exposed polyimide is then removed by hydrazine leaving windows in each surface with conductors extending across the windows on the respective opposite surfaces.

    摘要: A low-voltage, low-inductance device for storing electrical charge in a snubber circuit and a method of minimizing inductance in the snubber circuit using the device, wherein the device includes a plurality of extended electrodes, in parallel or series, that are joined to a positive conductor terminal at one end spray and at a negative conductor terminal at the other end spray so that end sprays of adjacent extended electrodes are alternately joined to the positive and negative conductor terminals. Accordingly, current flowing though adjacent extended electrodes is of substantially equal intensity but different in direction. As a result, inductance produced effectively cancels out that of adjacent extended electrodes.
