Description

Printed circuit board fixture

Technical Field

The utility model relates to the technical field of printed circuit boards, in particular to a printed circuit board clamping mechanism.

Background

Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. Since printed circuit boards are not typical end products, they are somewhat confusing in the definition of names such as: the motherboard for a personal computer is called a motherboard and cannot be directly called a circuit board, and although the circuit board exists in the motherboard, the motherboard is different from the motherboard, so that the two aspects cannot be said to be the same when evaluating the industry. For another example: because of the integrated circuit components mounted on the circuit board, the news media is called an IC board, but it is not substantially identical to a printed circuit board. By printed circuit board we generally say bare board-i.e. a circuit board without upper components.
