Abstract

The invention discloses a simple and convenient manufacturing method of a circuit board. The method comprises the following steps of cutting a copper clad plate of which two surfaces are coated with copper films, and then polishing an oxide layer on the surface of the copper clad plate to obtain the processed copper clad plate; bonding and transferring the processed copper clad plate and printed circuit board paper and firmly transferring carbon powder on the paper to the copper clad plate to obtain the transferred copper clad plate; and corroding and drilling the transferred copper clad plate and welding electronic components to obtain the circuit board. In the manner, the simple and convenient manufacturing method of the circuit board does not comprise a complicated step; operating personnel are convenient to learn and grasp; meanwhile, good performance of the circuit board can be ensured; the quality of the circuit board is not reduced; and the using effect is good.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a simple and convenient manufacturing method for a circuit board. Background technique [0002] Circuit boards are commonly used electronic products. Generally, circuit boards are divided into flexible silver paste circuit boards and rigid circuit boards. Flexible silver paste circuit boards are printed with silver-white silver paste conductive patterns and healthy bit patterns on a flexible film insulating substrate, also known as soft boards. Rigid printed circuit boards are mostly made of pre-impregnated phenolic or epoxy resin surfaces with copper clad plates on one or both sides, then laminated and cured, alternately connected by positioning systems and insulating bonding materials, and conductive patterns are interconnected according to design requirements. . In recent years, flexible-rigid combined circuit boards have also appeared for application. The existing circui...
