Abstract
The invention provides a printed circuit board hole drilling positioning device, which comprises a computer numerical control system, a mechanical hole drilling machine, a printed circuit board and a drilling machine pad plate, wherein the multilayer printed circuit board is arranged on the surface of the drilling machine pad plate, the drilling machine pad plate comprises a plurality of fixing holes and fixing pins, and the fixing holes are tangential with the edge of the multilayer printed circuit board. The invention also provides a printed circuit board hole drilling positioning method. Compared with the prior art, the printed circuit board hole drilling positioning device and the printed circuit board hole drilling positioning method have the advantages that before the plate element hole drilling, the computer control system and the mechanical hole drilling machine are used, fixing holes and positioning holes of the plate elements are manufactured according to the dimensions of the plate elements, the multilayer printed circuit board is fixed through the pins, and then, the multilayer printed circuit board is subjected to pattern hole drilling. Through the technology, the consistency of the plate elements and the pattern drilling belt program is ensured, so the technical problems of inconsistent distances from the holes of the multilayer printed circuit board to the edge, higher production cost and lower efficiency are solved.
Description
technical field [0001] The invention relates to the field of manufacturing printed circuit boards, in particular to a multilayer printed circuit board drilling positioning device and method. Background technique [0002] In order to adapt to the high-density and high-precision development of printed circuit board technology, more and more high-precision equipment has been widely used in the printed circuit board industry, and high-precision automatic exposure machines have gradually replaced manual and semi-automatic exposure machines. Become the main equipment for the production of printed circuit board factories. During the transfer and production of the outer layer graphics, because this equipment uses the camera image alignment technology to expose the board, the camera of the exposure machine relies on the film target and the board target to identify the exposure, and the positioning of the board by the exposure machine is based on the exposure positioning hole to the e...
