Title: Manufacture of circuit board
Inventor: KAMIMURA RIKIYA
IPC: H01L21/60
Filed: 1994-12-16
Abstract: PURPOSE: To provide a manufacturing method which is simple and ensures bonding in the manufacture of a circuit board. CONSTITUTION: When a thick film conductor 1 is covered with a resin containing a specific material for catching a halogen element before the process of soldering (covering layer 7), in the process of soldering, a halogen component contained in flux is adsorbed to an unsaturated linkage or an inorganic material contained in a covering resin before reaching the conductor surface and therefore, a halogen compound is not formed in the conductor surface. Therefore, the contamination of the conductor surface is completely eliminated and the connection is completely achieved at the time of wire bonding. Since high reliable aluminum wire bonding is realized, reliability such as the vibration resistance of a circuit board is enhanced and a device using the circuit board can be used even in a bad environment such as on vehicle equipment.  Also, since the connection failure of wire bonding is eliminated, there is an effect that the production yield of the circuit board is enhanced.

Filed: 1993-12-28
Abstract: PURPOSE:To obtain an easy method sending transmission line fault information from a transmission line interface of a transmission line into another transmission line interface in an ATM equipment. CONSTITUTION:When SDH termination sections 61-63 detect a transmission line fault, header conversion sections 81-83 send an in-equipment VP-AIS cell to a transmission line interface section being a connection destination of each VP via a VP switch 31.
