Abstract

The invention provides a manufacturing method of a circuit board, which comprises the steps of designing a circuit pattern; performing mirror image processing on a contour line of the circuit patternto obtain a mirror image contour line of the circuit pattern; coating a copper foil with a layer of strippable glue; attaching a sheet to the side, which is coated with the strippable glue, of the copper foil so as to form a composite sheet; tiling the composite sheet on an adsorption platform with an adsorption function; cutting a copper foil surface in the composite sheet along the mirror imagecontour line of the circuit pattern by using super fast laser so as to form a conductive pattern; stripping the redundant copper foil except for the conductive pattern from the composite sheet; laminating the copper foil surface on which the conductive pattern is formed in the composite sheet to a circuit board substrate coated with an adhesive layer; and stripping the sheet and the strippable glue from the circuit board substrate. The invention further provides a circuit board manufactured according to the manufacturing method. The manufacturing method provided by the invention of the circuitboard has the characteristics of environment-friendly manufacturing process and simplified flow.

Description

technical field [0001] The invention relates to the technical field of circuit board manufacturing, in particular to a method for manufacturing a circuit board and a circuit board manufactured by the method. Background technique [0002] At present, the production of conductive patterns in circuit boards generally adopts the method of chemical etching, that is, using an acidic or alkaline solution that can cause copper to undergo a reduction and oxidation reaction and oxidize it to copper ions, and place the copper clad laminate with the circuit pattern anti-etching layer on it. In the solution, make a series of chemical or electrochemical reactions with the solution, etch away the copper foil on the copper clad plate except the circuit pattern, keep the copper foil with the circuit pattern, and finally form the required conductive pattern. This process will produce a large amount of etching sewage containing copper ions during the production process, which will cause great ...
