Abstract

The present invention provides a preparation method of a circuit board and a circuit board. Two oppositely arranged anti-soldering clamp points and a wire are etched at the outer layer of the circuitboard, the outer layer of the circuit board is provided with at least one design region and an assistant design region, one end of the wire is connected with one of the two anti-soldering clamp points, the other end of the wire is connected with the other one of the anti-soldering clamp points, and the wire winds the periphery of each design region in the at least one design region and the periphery of the assistant design region; the two anti-soldering clamp points are respectively connected with the positive and negative poles of the power source to power on the wire; and the surface of theouter layer of the circuit board is subjected to electrostatic spraying with printing ink to obtain a circuit board sprayed with printing ink. In the preparation process of the circuit board, printingink charged particles are uniformly attached onto the surface of the outer layer of the circuit board so that the whole thickness of the printing ink layer of the surface of the circuit board is uniform and appropriate to improve the quality of the circuit board.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a method for preparing a circuit board and the circuit board. Background technique [0002] With the rapid development of electronic communication technology, the process technology of printed circuit board (referred to as PCB) is also constantly developing. In the manufacturing process of the circuit board, the ink solder mask technology on the surface of the circuit board is one of the most important process technologies in the PCB product process. [0003] In the prior art, the anti-solder technology of ink on the surface of the circuit board adopts an electrostatic spraying process; in the prior art, two anti-solder pinch points are set on the outer layer of the circuit board, and then a wire is arranged on the outer layer of the circuit board, And the wire is arranged on the periphery of the outer layer of the entire circuit board, one end of the wire is connected to...
