WORKING PANEL FOR MULTILAYER CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To provide a working panel for a multilayer circuit board that achieves product standardization and improves an yield by appropriately disposing first and second strips whose laminating positions are opposite each other in the center of a core and by locally spreading and canceling bending stress applied to the entire panel. SOLUTION: The working panel on which a plurality of strips comprising a number of circuit boards is arranged in a plane includes a first strip on which circuit layers having different circuit patterns are formed on upper and lower sides of the core, and a second strip on which circuit layers having different patterns are laminated on upper and lower sides of the core opposite to the circuit layer of the first strip.
