I think you should not know, in fact, PCB circuit board production and design is a meticulous work, a slight error will bring unnecessary trouble to future electronic products. For example: PCB circuit board corner routing problem. Next, we will make a detailed analysis of the problem of PCB on the corner line.

PCB circuit boards are manufactured and designed with full consideration of their beauty. In the circuit board corner routing, there must be a form of choice, design needs to set PCB circuit board corner routing form of corner mode. 45 degree, 90 degree and arc can be selected. Generally, sharp corners are not used. It is better to use arc transition or 45 degree transition to avoid 90 degree or more sharp corner transition.

Whether PCB or PCB, "Aluminum baseline circuit board, single-sided circuit board, they all have a common name, that is, circuit board or circuit board. These circuit boards are designed to be treated with great care and are confused by a small lump in their body. So Koyou Circuit is also excellence in this respect. In the process of making PCB circuit boards, it can make it both portable and good in performance. It is right to choose excellent ones.

When the lead of PCB circuit board passes through the two pads and is not connected with them, it should keep the maximum and equal distance with them. When the lead of the same wire and wire passes through the two pads instead of connecting with them, it should keep the maximum and equal distance with them, and the distance between them should also be uniformly equal and maintained. Maximum. The connection between the wire and the pad should be as smooth as possible to avoid the appearance of small pins. Tear droplets can be used to solve the problem. When the central distance between the pads is less than the outer diameter D of a pad, the wire width can be the same as the diameter of the pad; if the central distance between the pads is greater than D, the wire width should not be greater than the diameter of the pad.
