The invention provides a manufacturing method for PCB plug hole aluminum sheets. The manufacturing method comprises the following steps of generating aluminum sheet aperture data; preprocessing the aluminum sheets; pasting a film; transferring a pattern; performing etching; and removing the film. Compared with the prior art, the method has the advantages that a manufacturing mode of drilling the aluminum sheets by a traditional numerical control drilling machine is changed; the problems that the productivity of the numerical control drilling machine and the plug hole aluminum sheet manufacturing efficiency of the numerical control drilling machine are low are solved; quick and high-precision manufacturing of the plug hole aluminum sheets is realized; and a traditional mode of manufacturinga plug hole aluminum sheet each time due to a single material number and a single drilling parameter is subverted. The plug hole aluminum sheets with different specifications and different types canbe produced in batches, so that the manufacturing efficiency of the PCB plug hole aluminum sheets is improved, the flow of a PCB plug hole manufacturing process is accelerated, and the manufacturing cost of the aluminum sheets is reduced.
