Background

In the production process of circuit boards, the copper electroplating process is an indispensable and very important procedure. The quality of the copper plating directly affects the stability of other subsequent surface treatment procedures, and even the quality of finished circuit boards. And one of the factors in the quality of the copper plating is "average degree".

In the traditional copper electroplating process, an anode titanium basket is generally used, and phosphorus copper balls are stored in the anode titanium basket. An anode titanium basket, a single end opening of which is exposed out of the liquid level of the plating solution; the other end is sealed and immersed in the plating solution. The back of one end of the opening is provided with a hook anode titanium basket which is provided with a hook and is directly hung on an anode copper rod or a titanium coated copper rod at the plating bath side.

In the copper electroplating process, the phosphor copper balls in the anode titanium basket are gradually dissolved, reduced and fall down to the bottom of the anode basket. The upper section of the anode basket is gradually empty, and the phosphor copper balls must be replenished. After a period of time, the size deviation of the phosphor copper balls in the anode basket is increased, the contact area is unbalanced, the internal resistance is increased, the current density is uneven, and the small phosphor copper balls with poor conductivity fall to the bottom of the anode basket, so that the copper plating layer on the circuit board is 'thick on top and thin on bottom', and the capacitor is finally formed.
