Positioning device for frame for circuit board

The present invention relates to a positioning device for a frame for a circuit board, and more particularly to a positioning device for a power supply plating or an anode processing circuit board having a better fixing effect to improve processing precision and quality.

A printed circuit board is a basic component of a general electronic product that carries electronic components, and serves as a member for electrical connection between electronic components. However, the traditional printed circuit board is only a single-layer circuit structure, which cannot meet the requirements of high-density wiring. Therefore, it has been developed into a multi-layer circuit structure, which can meet the needs of the multi-functional high wiring density of electronic products. Achieve the purpose of reducing the board area.

It is also known that a printed circuit board has a considerable thickness and hardness, and a multilayer circuit is formed by build-up or laminated, and the whole plate is used in a wet process such as plating or etching. The circuit board is hung on the fixture and then immersed in the electrolytic cell to plate a metal layer on the circuit board, such as a copper wire or a plated through hole (PTH), or an etching metal layer. Such as removing the seed layer. For the purpose of thinness and use as a substrate for chip packaging, the thickness of the circuit board has become thinner; the circuit board is usually fabricated on a large-area full-size circuit board. a plurality of identical lines, and the thickness of the board is very thin relative to its own area, and the board is suspended in parallel in a hanging basket structure and then placed in an electrolysis The bath is plated or etched.
