Problems solved by technology

[0005] On the one hand, the process of making circuit boards in the prior art is complicated. If it is a double-sided circuit board with simple circuit graphics, it takes too much time to make circuit graphics, which affects the delivery time of the circuit board; on the other hand, due to the current In the existing technology, copper foil blanking is used for processing, which is a waste of copper foil and high cost

Abstract

The invention discloses a manufacturing method of a circuit board. The method comprises the steps that a circuit board mould is manufactured, and the surface of the circuit board mould is provided with convex line graphs; the circuit board mould and a false core board are laminated so that concave line graph grooves are formed on the false core board; and copper deposition and electroplating are performed on the false core board, the line graph grooves are filled through electroplating, and corresponding line graphs are formed in the line graph grooves so that the circuit board is manufactured. The manufacturing method of the circuit board is used for solving the existing problems of manufacturing of the circuit board in the prior art so that manufacturing rate of the circuit board is accelerated.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a method for manufacturing a circuit board. Background technique [0002] Printed Circuit Board (PCB), also known as printed board or circuit board, is one of the important components of electronic products. Electronic products made of circuit boards have high reliability, good consistency, high mechanical strength, light weight, With the advantages of small size and easy standardization, almost every kind of electronic equipment, from small electronic watches and calculators to large computers, communication equipment, and electronic radar systems, as long as there are electronic components, the electrical interconnection between them must be used circuit board. [0003] The current conventional process for making double-sided circuit boards is: blanking, drilling, copper sinking, electroplating, external drawing, external corrosion, external inspection, solder mask, exp...
