Title: Printed wiring board with injection molded board
Inventor: MARUSERU HEERUMAN
IPC: H05K3/42
Filed: 1989-09-28
Abstract: PURPOSE: To easily perform solder block lacquering by constituting the width of a narrow groove-shaped recessed part, so that an applied metal cover can reach the surface of a board and forming the width of a plane-shaped recessed part wide such that a fixed gap can remain between the metal cover inside this recessed part and the surface of the board. CONSTITUTION: When producing a printed wiring board, it is started from a board 1 provided with a groove-shaped recessed part 30 almost V-shaped, corresponding to a conductor pattern conduction image as an injection molding section, plane-shaped recessed part 40, a and through-hole 60 protruding from that recessed part. Next, after a surface 10 of the board 1 is treated ordinarily, a lacquer layer 4 is applied as an ordinary plating regist. Then, the lacquer layer is applied by roller coating but in that case, the recessed parts 30 and 40 are separated for a gap A. In this case, a growth seed 5 is applied and activated later, and continued by having the range not protected with the lacquer layer 4 coated with a metal layer 2 by the method of chemical deposition in the state of no current.  Thus, the time for covering the metal 2 is suitably determined and the recessed part 30 is made sufficiently thick for completely reaching the surface of the board. Afterwards, a solder block lacquer 6 is applied by roller coating.

Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To prevent charging current of a cable from flowing to an external semiconductive layer of a cable core, to reduce voltage drop and heat generation and to improve long time reliability of the cable by laterally winding or longitudinally attaching a water absorbing tape provided with a semiconductive water absorbing layer on one surface of a metallic tape on the cable core by directing a semiconductive water absorbing layer to the outside. SOLUTION: A hydrotaxis-proof cable is provided with a water absorbing tape 4, metallic sheath 3 and a protective coating layer on a cable core 1. The water absorbing tape 4 is made by laminating a semiconductive water absorbing layer on one surface of a metallic tape, semiconductive rubber containing a conductive material on the other surface and a plastic tape. Therefore, since the metallic tape of low resistance exists in the water absorbing tape 4, charging current of the cable flows along the metallic tape and charging current concentrating in a valley part of the metallic sheath 3 flows in a semiconductive water absorbing layer with little electric resistance in the thickness direction. As a result, voltage drop and heat generation can be reduced.
