Example Embodiment

In view of the technical problems existing in the prior art, the embodiments of the present invention provide a method for manufacturing a standard pressing plate and a standard pressing plate, so as to ensure the qualification of the standard pressing plate, thereby improving the mass production of the standard pressing plate as the standard. The pass rate. The method includes: arranging a test part (such as a test hole) on a core board for pressing and making; stacking a plurality of the core boards, and performing a pressing operation to obtain a pressing board; according to the test parts of the plurality of core boards The position of, in the corresponding position of the pressing plate (referring to the position of the pressing plate corresponding to the test part of each core plate in the pressing plate, such as the position of the geometric center of the test part) mechanically drilled to obtain the mechanical hole ; Perform interlayer offset detection on the mechanical...

Abstract

The invention discloses a standard laminated plate and a manufacturing method thereof, which aim to improve the passing rate of laminated plates. The method comprises the following steps of: setting a test part on core plates for lamination and manufacture; stacking a plurality of the core plates and performing laminating operation to obtain the laminated plate; according to the position of the test part of a plurality of the core plates, mechanically drilling the corresponding position of the laminated plate to obtain mechanical holes; performing interlayer offset detection on the mechanically drilled laminated plate to judge whether the laminated plate is qualified. The technical scheme of the invention ensures that the standard laminated plate is the qualified laminate plate, thereby improving the passing rate of the laminated plates which are manufactured in batch by taking the standard laminated plate as the standard, and reducing the rejection rate of the laminated plates manufactured in batch.

Description

Method for making standard plywood and standard plywood technical field The invention relates to the field of manufacturing printed circuit boards, in particular to a method for manufacturing a standard laminated board and a standard laminated board. Background technique At present, in the process of producing a PCB board (Printed Circuit Board, printed circuit board), each layer of core board is laminated to obtain a laminated board, and the laminated board needs to be mechanically drilled before entering the next process. At present, the method of mechanically drilling the plywood is mainly to directly drill holes on the four corners of the plywood, but this method may have the following technical problems: due to the abnormal expansion and contraction of the core board before lamination, the inner layer is biased Or, there are problems such as interlayer offset after lamination, which makes the plywood scrapped when the plywood is mechanically drilled; if the plywood ne...
