[0029] In order to make the present invention easier to understand, the present invention will be further described in conjunction with the accompanying drawings, but the embodiments in the accompanying drawings do not constitute any limitation to the present invention.
[0030] The invention relates to a manufacturing method of a multilayer printed circuit board, in particular to a judging method for judging whether the positions between layers are shifted during the manufacturing process of the multilayer printed circuit board. It can meet the interlayer offset judgment requirements of all products.
[0031] figure 1 A flow chart of a method for detecting position deviation between layers of a multilayer printed circuit board according to an embodiment of the present invention is shown.
[0032] The method includes the following steps:
[0033] Step S01, select the even-numbered or odd-numbered layers in the printed circuit board, and set a number of circular alignment mar...
