  • CIRCUIT BOARD WITH ANTI-CORROSION PROPERTIES AND ELECTRONIC DEVICE HAVING THE SAME
    Publication number: 20240172370
    Abstract: A circuit board with anti-corrosion properties, a method for manufacturing the circuit board, and an electronic device are provided. The circuit board includes a circuit substrate, a first protective layer, and a second protective layer. The circuit substrate includes a base layer and an outer wiring layer formed on the base layer. The circuit substrate further defines a via hole connected to the outer wiring layer. The first protective layer is formed on the outer wiring layer and an inner sidewall of the via hole, and is made of a white oil. The second protective layer is formed on the first protective layer.
