Abstract:
Disclosed are a circuit board having an integrated tact reset switch and a manufacturing method therefor, relating to the technical field of integrated circuit manufacture. The invention comprises a printed circuit board, an outer frame support being pressed and fixed to a top of the printed circuit board, a movable metal dome being placed in the outer frame support, and a protective film being pressed and fixed to the top of the metal dome. A marking line is provided in a TOP surface of the printed circuit board, contact positive and negative separation lines are provided in the TOP surface of the printed circuit board, and a solder resist window is disposed at the TOP surface of the printed circuit board. A positive feed point and a negative feed point are provided on a position of the surface of the TOP surface of the printed circuit board where the solder resist window is located. The TOP surface of the printed circuit board is provided with a through hole, the through hole extending to a BOT surface of the printed circuit board. In the present invention, by means of configuring a printed circuit board, an outer frame support, a metal dome and a protective film, a tact reset switch is directly used as a component of the circuit board. The technique is simple and uses fewer processes, which helps reduce production costs of the product.
