More Information
Summary:A keyboard circuit board capable of preventing chemical erosion can include a substrate, a conduction layer, a protection layer and an isolation layer. The conduction layer is formed on the substrate. A part of the protection layer is disposed on the substrate, and the other part of the protection layer is disposed on the conduction layer. The isolation layer has a first surface and a second surface opposite to each other. The first surface is connected to the conduction layer, and the second surface is connected to the protection layer, so as to prevent chemical substance from leaking into a gap between the conduction layer and the protection layer.
