​PCB board deformation is often encountered in the production process of electronic products. This situation will not only lead to the decline of the function of electronic products, but also reduce the service life of electronic products, reduce the user experience, and bring a lot of trouble to enterprises.

In the high-speed PCB design, the clock and other key high-speed signal lines need to be shielded. If there is no shielding or only partial shielding, EMI leakage will be caused. It is suggested that the shielding wire should be grounded by drilling every 1000mil.

Switching regulators for voltage conversion use inductors to temporarily store energy. These inductors are usually very large in size and must be positioned in the printed circuit board (PCB) layout of the switching regulator. The current will not change instantaneously, but it is not difficult to change the inductance through. Changes can only be continuous, usually relatively slow.

For electronic equipment, a certain amount of heat will be generated when working, so that the internal temperature of the equipment will rise rapidly. If the heat is not sent out in time, the equipment will continue to heat up, the device will fail due to overheating, and the reliability of electronic equipment will decline. Therefore, it is very important to heat the circuit board.
