Description

Technical Field

[0001] The utility model relates to the technical field of PCBA boards, in particular to an anti-static PCBA board. Background Art

[0002] Printed circuit board, also known as printed circuit board, printed circuit board, often uses the English abbreviation PCB, is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board. Before the emergence of printed circuit boards, the interconnection between electronic components was directly connected by wires to form a complete circuit. Now, circuit breadboards only exist as effective experimental tools, and printed circuit boards have become an absolute dominant position in the electronics industry. In the early 20th century, in order to simplify the production of electronic machines, reduce the wiring between electronic parts, and reduce production costs, people began to study the method of replacing wiring with printing.

[0003] When using traditional PCBA boards, there are a lot of electronic components on them. During the installation process, the electronic components will cause friction due to shaking, which will generate static electricity on the surface of the PCBA board. When the static electricity is large, the electronic components on the PCBA board may be broken down, thereby destroying the normal use of the PCBA board. At the same time, static electricity will also be generated on the outside of the PCBA board, affecting the use of the PCBA board. Therefore, it is necessary to propose an anti-static PCBA board to solve the above problems. Utility Model Content
