Whether it is a double-layer board or a multi-layer board, the area should be increased as much as possible. Consider the ESD characteristics of the chip itself when selecting the chip. These are generally mentioned in the chip description, and even the performance of the same chip from different manufacturers will be different. Pay more attention to the design, consider the comprehensive point, and make the performance of the board will be guaranteed. However, the problem of ESD may still occur, so the protection of the organization is also very important for the protection of ESD.
