to consider electrical characteristics such as EMI, EMC, ESD, and signal integrity, as well as the heat dissipation of mechanical structures and high-power chips, on this basis, consider the appearance of the circuit board. Therefore, PCB layout is an art, specifically an art of door compromise. Before learning to explore PCB wiring, you may see a variety of PCB wiring rules in a variety of reference books, even if many rules have the same meaning to

Summary:
MSP430 single-chip microcomputer 8 kV electrostatic dead machine,
Arm will not crash much, but static electricity is easy to penetrate into arm's Io,
Then, the I/O short-circuit chip is exposed to heat. When the chip is damaged, some chips are cracked,
However, it can be restored after power failure,
No external guard is used,
Reset after static electricity is not easy to enable, must be powered on,
According to the Internet, EMI conductive paint is sprayed inside t
