Some problems are not easy to find in the early stage of circuit fabrication. They often appear in the later stage, such as too many wire holes, copper sinking process will bury the hidden danger. Therefore, the design should reduce the line hole as much as possible. Parallel lines are too dense to be welded together easily. Therefore, the linear density should be determined depending on the level of the welding process. The distance of solder joint is too small, which is not good for manual welding, so the welding quality can only be solved by reducing the working efficiency. Otherwise, it will leave a hidden danger. Therefore, the determination of the minimum distance of solder joint should consider the quality and efficiency of welding personnel.
If you want to improve the design efficiency and product quality of double sided PCB board, it is necessary to fully understand and master the points for attention in the design of double sided PCB board. You keep five key points in mind and it can correct errors in production, it saves a lot of time and cost.
In the layout design of the double sided PCB board, the unit of the circuit board should be analyzed, and the layout design should be carried out according to the function of the circuit board.（fabrication pcb）
