Multi-layer circuit board capable of being applied with electrical testing and method for manufacturing the same
A multi-layer circuit board capable of being applied with electrical testing includes a patterned metal-interface layer, a metallic delivery loading plate, an electrical connection layer, a conductive corrosion-barrier layer, a bottom dielectric layer, and a multi-layer circuit structure. The multi-layer circuit structure is disposed on the delivery loading plate through the bottom dielectric layer. The top-layer circuit of the multi-layer circuit structure is electrically connected to the conductive corrosion-barrier layer through the bottom-layer circuit and the electrical connection layer. The delivery loading plate and the patterned metal-interface layer expose the conductive corrosion-barrier layer. Therefore, before the multi-layer circuit board is packaged, an electrical testing can be applied to the multi-layer circuit board to check if it can be operated normally. Hence, costs for figuring out reasons of the unqualified electronic component can be reduced, and responsibilities for the unqualified electrical testing result of the electronic component can be clarified.
