Background

The name of the printed circuit board is that the printed circuit board is also called printed circuit board, is an important electronic component, is a support body of the electronic component, is a carrier for electrical interconnection of the electronic component, and is slightly disordered in the definition of the name because the printed circuit board is not a general terminal product, for example: 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;

this circuit board need use a test fixture when the production shaping, and original test fixture manual operation is convenient enough, and the measuring accuracy is relatively poor, leads to inefficiency.
