Problems solved by technology

The process of multilayer printed circuit boards is complicated, the processing precision is very high, and the cost is much higher than that of single-layer boards and double-layer boards.
[0009] In the case of a single piece, a small amount of production, or a printed circuit board that needs to be obtained as soon as possible, the current printing method is difficult to achieve

Embodiment

[0028] A printing process for a printed circuit board, comprising the steps of:

[0029] (1) Select the copper clad board: select the substrate, and then cut the size and size of the copper clad board according to the requirements of the printed circuit board design;

[0030] (2) Copy printed circuit: Use carbon paper to trace the designed printed circuit diagram on the copper foil surface of the copper clad board, place the carbon paper on the copper foil surface, stick it firmly with adhesive paper or tape, and wait until it is printed with a pencil or carbon After drawing the graphics with the pen and checking them for correctness, uncover them, and the printed circuit diagram is drawn on the copper-clad board;

[0031] (3) Tracing board: Dip the paint with a brush or a straight line pen and paint it according to the copied circuit diagram.

[0032] Wherein, before cutting the copper-clad board in the step (1), the edge of the copper-clad board is polished with water sandp...

Abstract

The invention relates to the technical field of production and manufacturing of a printed circuit board, and specifically to a printing process for the printed circuit board. The printing process comprises the following steps of (1) selection of a copper-clad plate: choosing a substrate, and cutting dimensions and sizes of the copper-clad plate according to the design requirement for the printed circuit board; (2) copying of the printed circuit board: overprinting a designed printed circuit diagram on the copper foil surface of the copper-clad plate through carbon paper; putting the carbon paper on the copper foil surface, and enabling the carbon paper to be fixed by gummed paper or an adhesive tape, and peeling off the carbon paper after the circuit diagram is traced without errors after verification, and obtaining a traced printed circuit diagram on the copper-clad plate; and (3) tracing plate: tracing and coating by a writing brush or a ruling pen with coating according to the copied circuit diagram. A simple plate-tracing manufacturing method is adopted, and the printed circuit board can be obtained rapidly and effectively; and meanwhile, the method is simple and convenient to operate, and high in practicability.

Description

technical field [0001] The invention relates to the technical field of circuit board production and processing, in particular to a printing process of a printed circuit board. Background technique [0002] The development of the electronics industry, especially the development of microelectronics technology, has made the application of integrated circuits more and more extensive, and subsequently, new requirements have been put forward for the manufacturing process and precision of printed circuit boards. The types of printed circuit boards have developed from single- and double-sided boards to multi-layer boards, rigid and flexible boards, and the printed lines have become thinner and thinner. But the most widely used are single-sided printed circuit boards and double-sided printed circuit boards. [0003] Printed circuit boards are also called printed circuit boards, which can be referred to as printed boards, and are divided into the following categories: [0004] 1) Ri...
