Embodiment Construction

[0068] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0069] It should be noted that although the functional modules are divided in the system schematic diagram and the logical order is shown in the flow chart, in some cases, it can be executed in a different order than the module division in the system or the flow chart steps shown or described. The terms "first", "second" and the like in the specification and claims and the above drawings are used to distinguish similar objects, and not necessarily used to describe a specific sequence or sequence.

[0070] The basic process of making printed circuit boards is divided into positive film and negative...

Abstract

The invention discloses an isolated graph design method and device, a storage medium and computer equipment. The method comprises: obtaining a circuit pattern of an isolated graph, obtaining a circuit pattern of the isolated graph, pre-designing an auxiliary pattern according to the circuit pattern of the isolated pattern, performing pattern transfer, electroplating and etching on the isolated pattern and the auxiliary pattern according to a positive film process, and performing pattern transfer and etching on the isolated pattern and the auxiliary pattern according to a negative film process to complete the design of the isolated pattern. According to the invention, by designing the auxiliary pattern, the problem of line width out-of-tolerance in the positive and negative sheet processes caused by pattern isolation can be avoided, and the problem that the copper thickness exceeds the standard in the positive sheet process can also be avoided.

Description

technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to an isolated graphic design method, device, storage medium and computer equipment. Background technique [0002] The basic process of printed circuit board production line is divided into positive film and negative film process, refer to Figure 1 to Figure 3 , the basic plan of the positive film process is: pattern transfer, pattern electroplating, pattern etching, and finally obtain the required circuit; refer to Figure 4 and Figure 5 , the basic plan of the negative film process is: pattern transfer, pattern etching, and finally get the required circuit. [0003] There are isolated graphics locally. When the positive graphics are electroplated, the current density of the isolated graphics is greater, and it is easy to have problems such as thicker copper thickness and sandwich film (the thickness of electroplated copper is higher than that of the anti-plating ...
