The invention discloses a circuit board manufacturing method. The circuit board manufacturing method includes: printing solder resist ink on a circuit board formed with circuits and a solder pad; attaching a solder resist exposure film on the solder resist ink on the circuit board, wherein the solder resist exposure film is provided with a solder pad window and an outline winnowing line, the solder pad window corresponds to the solder pad on the circuit board, and the outline windowing line corresponds to the outline of the to-be-shaped-circuit-board; treating the circuit board attached with the solder resist exposure film via exposing; subjecting the exposed circuit board to developing and corroding via corresponding solution so as to remove the solder resist ink corresponding to the solder pad window and the outline windowing line and form a solder resist layer on the parts; and cutting to shape the developed and corroded circuit board. Via above circuit board manufacturing method, after the outline of the circuit board is completely processed, a worker can judge whether the outline of the circuit board is qualified or not via detecting whether trails at edges of the outline of the circuit board are complete or not, the detecting method is quick, and circuit board detecting efficiency and circuit board manufacturing efficiency are improved.
Description
technical field [0001] The invention relates to a method for manufacturing a circuit board, in particular to a method for manufacturing a circuit board which is convenient for shape detection and a circuit board manufactured by the method. Background technique [0002] Circuit board (PCB) refers to a board on which a printed circuit is made on an insulating substrate according to a predetermined design, and a conductive pattern is provided between components. The circuit board is one of the important electronic components, the support of electronic components, and the provider of electrical connections for electronic components. [0003] The general circuit board production process includes cutting, drilling, copper sinking, full board plating, outer layer dry film, graphic plating, etching, solder mask, characters, tin spraying, forming, electrical testing, FQC, FQA, packaging, etc. [0004] The shape of the circuit board is usually processed by a CNC milling machine.
