With the development of the electronics industry, the requirements for printed boards are getting higher and higher. The high density of the printed board design, the thin wire, the small aperture tend to be faster and faster, and the production process of the printed board is more and more perfect.
At first glance, the PCB is similar in appearance regardless of its inherent quality. It is through the surface that we see the differences that are critical to the durability and functionality of the PCB throughout its lifetime.
The standard is to make the PCB factory's engineering staff see at a glance, without misunderstanding, resulting in a wrong PCB.
It can be classified according to PCB use, substrate type, structure, etc., and is generally divided by PCB structure.
Basic grounding method: There are three basic grounding methods in electronic equipment: single-point grounding, multi-point grounding, and floating ground.
