Abstract
An anti-static circuit board structure and a fabrication method thereof are proposed. The circuit board structure includes: a circuit board having at least one circuit layer thereon, wherein the circuit layer has a plurality of electrical connection pads; a dielectric layer formed on at least one surface of the circuit board to cover the circuit layer, and having a plurality of first openings corresponding to the electrical connection pads such that the electrical connection pads are exposed; a protection layer formed on the dielectric layer, and having a plurality of second openings corresponding to the electrical connection pads such that the electrical connection pads are exposed; and a solder mask layer formed on the protection layer and the dielectric layer, wherein the solder mask layer has a plurality of third openings corresponding to the electrical connection pads of the circuit board such that the electrical connection pads are exposed, and the solder mask layer further has at least one fourth opening for exposing a portion of the protection layer, such that static on the protection layer can be connected to an external structure and grounded. Therefore, the protection layer can attract static and direct the static to the external structure so as to release the static and prevent damage to a semiconductor chip mounted on the circuit board.
