Multilayer printed wiring board and method of manufacturing the same |
摘要 |
A multilayer printed wiring board having a wiring lead-out port has a signal circuit conductor perfectly covered by an earth circuit in its inside and a wiring lead-out port. A signal circuit conductor having a branch pattern is preferable. A large number of products can be easily manufactured with good size reproducibility. The multilayer printed wiring board is manufactured by selectively etching the copper of a cladding sheet manufactured by bonding a copper foil to a nickel foil with 0.1-3 % reduction and forming a signal circuit conductor covered by an earth circuit and the wiring lead-out port.
