Abstract

The invention discloses a printed circuit board design drawing generation method, a printed circuit board and a manufacturing method of the printed circuit board, and belongs to the field of printed circuit board design. The design drawing generated by the method for generating the design drawing of the printed circuit board comprises a first network pattern, a second network pattern, a first bonding pad pattern, a second bonding pad pattern, a first wire pattern, a second wire pattern and a first mark pattern. The simulation circuit of the design drawing is generated according to other graphs except the marked graph in the design drawing. In the simulation circuit of the design drawing, the first bonding pad pattern and the second bonding pad pattern are spaced from each other, so the first network pattern and the second network pattern are not connected together, the situation that two signal networks on the printed circuit board design drawing are connected together and cannot pass circuit detection can be avoided, and the accuracy of circuit detection is improved.

Description

technical field [0001] The present application relates to the field of printed circuit board design, in particular to a method for generating a design drawing of a printed circuit board, a printed circuit board and a manufacturing method thereof. Background technique [0002] In printed circuit boards, two different signal nets sometimes need to be connected to each other. For example, in a digital-analog hybrid circuit, the analog signal ground network and the digital signal ground network are in different positions, but they need to be connected together to avoid different zero potential reference points provided by the two ground networks. [0003] In the related art, each signal network is connected to a pad, and two pads are partially overlapped so that two different signal networks are connected together. However, when performing circuit detection on the simulation circuit of the design diagram of the printed circuit board, the two signal networks connected together o...
