Problems solved by technology

However, when using this anode screen cloth for electroplating, there will be an edge effect. The power lines around the PCB board will be denser than the central power lines, making the coating around the PCB board thicker than the middle one. In severe cases, the electroplated PCB board cannot use
In order to avoid all waste, it is often to cut off part of the PCB board with too thick coating around it, or use physical or chemical methods to treat the overly thick coating to make it thinner, but in this way, it increases the process while causing waste. , which brings inconvenience to the production

Abstract

The invention belongs to the field of the anode shielding for electroplating and particularly relates to an anode shielding used for increasing the electroplating uniformity. The anode shielding contains an anode shielding frame and an anode shielding cloth which can be fixed on the anode shielding frame in a detachable manner, wherein the internal frame of the anode shielding frame is completely covered with the anode shielding cloth. The anode shielding also contains four flat plates with through holes, wherein the flat plates are fixed at the upper, lower, left and right edges of the anode shielding cloth respectively. The anode shielding provided by the invention uses the flat plates which are fixed on the anode shielding frame and have the through holes, to adjust the density of power lines around a PCB and ensure that the surface coating of the PCB is uniform in thickness; and the anode shielding provided by the invention has simple structure, and the flat plates with the through holes on the anode shielding can be changed according to the specific situation.

Description

technical field [0001] The invention relates to an anode screen for electroplating, in particular to an anode screen for improving the uniformity of electroplating. Background technique [0002] In the process of PCB board production, the surface of PCB board needs to be electroplated. As an important part of integrated circuits, integrated circuit products have very high requirements for PCB boards. The connection between electronic components depends on the plating layer on the surface of PCB boards. Therefore, whether the thickness of the coating on the surface of the PCB board is uniform plays a vital role in the connection between electronic components. [0003] In the prior art, it is often necessary to use an anode screen cloth when electroplating a PCB board, and the anode screen cloth plays a role of filtering impurities, and at the same time allows the power lines to pass through more uniformly. However, when using this kind of anode screen cloth for electroplatin...
