Title: Inspecting instrument for printed wiring board
Inventor: SUZUKI KOICHI
IPC: G01R31/02
Filed: 1986-08-29
Abstract: PURPOSE:To inspect a printed wiring board with making any indentation of a probe by providing a protection sheet made of a pressure conductive elastic body to the surface of the printed wiring board that the probe contacts. CONSTITUTION:A beam and a carriage are moved at right angles to each other and the probe 6 is set at necessary positions in prescribed order and then pressed against the protection sheet 5. Then, the pressed part of the protection sheet 5 becomes conductive to connect the probe 6 to the circuit pattern of the printed wiring board 4 electrically. In this state, the electrostatic capacity between a conductive plate 2 and the printed wiring board 4 or the resistance of the circuit pattern is measured by an electrostatic capacity meter 8 and a resistance meter 9 to inspect whether or not the circuit pattern is normal. Thus, the printed wiring board 4 is inspected without bringing the probe 6 into direct contact with the circuit pattern, so indentation due to the collision of the probe 6 is prevented from being generated.

Title: Production of prepreg
Inventor: MAKINO SHUJI
IPC: H05K3/02
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of copper foil wrinkles by a method in which after a fiber backing being impregnated with a kind of thermosetting resin varnish, the backing is heat-dried, a prepreg main body in which the thermosetting resin was cured to a B stage is pressurized while being cooled, and the surface is smoothed. SOLUTION: A lengthy fiber backing 1 such as a glass cloth, after being impregnated in an impregnation tank 3 with a kind of epoxy resin varnish 2 deformed by vacuum deaeration, is heat-dried continuously by a drier 4 to prepare a prepreg in a B stage. The prepreg which is discharged continuously from the drier 4, in the course of being cooled, is passed through two press rolls 6 and press-pinched, and the surface is smoothed. In this way, by using the remaining heat of the prepreg, the surface of the prepreg discharged continuously from the drier 4 can be smoothed. Even when the prepreg is used for copper-clad laminated board using very thin copper foil, the generation of copper foil wrinkles can be reduced.
