Description

Plating basket {plating basket}

The present invention relates to a plating basket for use in plating operations for the manufacture of thin-film circuit boards such as PCBs.

In general, thin-film circuit boards, such as a printed circuit board (PCB), are manufactured through a plating process, and are mainly a substrate for manufacturing a circuit board (hereinafter, referred to as a "substrate") by electrolytic plating (electroplating) or electroless plating (chemical plating). The method proceeds by forming various metal layers on the side.

In particular, the electroless plating operation is carried out in a state where the plating basket is immersed in the plating solution of the plating bath by placing several substrates in the plating basket.

The plating basket has a structure capable of stably supporting and fixing the edges of the substrates so that the substrates can be erected in an unfolded state to be contained in an array facing each other.

Briefly describing the general structure of the plating basket, the basket body having an internal space in which the substrate is contained, the supports formed to support the opposite edges of the substrates inside the basket body, and the sides of the supports Fixtures disposed on the basket body to press or release the edge of the substrate supported on the substrate, and to operate the fixtures to press or release the substrate by moving the fixtures with cam contact force. It comprises a cam control unit for controlling.

In addition, the cam operating part is fixed to the edge of the substrate by pushing the end of the fastener to the outer surface of the cam when the cam is rotated while the outer surface of the cam (Cam) and one end of the fastener are in contact with each other. It is made of a structure for controlling the operation of the fixture in the cam operation method.

According to the structure of the plating basket, it is very important to quickly and stably hold the opposite edges of the substrates so as not to abnormally flow when fixing a plurality of substrates contained in the basket body.

However, the fixing part and the operation part provided in the plating basket may cause various problems when the various substrates are held in the basket body.

That is, the operation unit of the cam operation method has a disadvantage that the contact surface is prematurely worn by friction because power is transmitted in a state where friction occurs when the cam is rotated while the cam and the fixture end side are in contact with each other.

In addition, when friction occurs on the contact surface during operation of the cam, metal dust may be easily generated by wear. In particular, when these metal dusts are introduced into the plating bath, contamination of the plating solution and deterioration of plating quality may be a factor. Can be.

In addition, since the fixing part and the operation part are fixedly installed on the basket main body and cannot be properly adjusted in position, for example, various operating environments and operation compatibility that match the substrate size cannot be expected. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems occurring in the prior art,
