The main function of PCB is to make various related parts connected to each other according to the designed circuit. The formed circuit pattern is formed by a printing technique on a surface of the insulating substrate or a wiring board formed therein. With the market demand for light and thin electronic products, the area of the circuit board is gradually reduced. And the functionality of electronic products has increased, and the number of parts has increased. The complexity of board layout design is much increased. The design procedure of the β general circuit layout is mainly divided into four stages, which are the placement stage, the routing stage, the test point arrangement (test p〇int) stage, and the release stage. . The positioning stage is to place the parts on the board. However, when there is an error in the position where the right parts are placed on the board, it may cause problems in subsequent board assembly. The poorly designed circuit boards must be disposed of at a time, and cannot be reworked, which seriously increases manufacturing costs. SUMMARY OF INVENTION 5 200825815,
