The invention relates to a method for forming a plug hole in a circuit board, which is used for forming a resin plug hole in the circuit board. The method comprises the following steps: placing the circuit board in a vacuum chamber; Obtaining position information and size information of each metallized via to be filled in a preset coordinate system; Obtaining a filling amount corresponding to eachto-be-filled metallized via hole according to the size information of each to-be-filled metallized via hole; sequentially moving resin nozzles to positions corresponding to each of the metallized vias and filling resin into metallized via holes with resin corresponding to the filling amount. The invention also provides a circuit board plug hole device. Compared with the prior art, the circuit board jack hole method and the circuit board jack hole device enable the process of forming the resin jack hole on the circuit side to omit the step of forming the intermediate shield on the surface of the circuit board, greatly shorten the processing time of the circuit board, and effectively improve the processing efficiency of the circuit board.
Description
technical field [0001] The invention relates to the technical field of circuit board manufacturing, in particular to a circuit board plugging method and circuit board plugging equipment. Background technique [0002] With the development of printed circuit boards, based on the demand for dense wiring on the circuit board and the requirements for reliability, it is necessary to adopt plug hole design for some via holes to form resin plug holes. The current plugging process mainly includes a selective plugging method and a full-plate plugging method. Based on the requirement of high reliability, in the manufacture of circuit boards, the circuit board is usually placed in the vacuum environment provided by the plugging equipment to realize selective plugging. At present, selective plug holes usually use some intermediary barriers (for example: aluminum sheet frame, dry film, etc.) hole requirements. [0003] However, in this method of using an intermediary barrier to realize...
