Electroplating equipment It is an equipment for electroplating objects. The electroplating solution in the electroplating equipment has good fluidity and conductivity. The electroplating solution can improve the bonding force and appearance quality of copper, gold, silver and other metals by removing oxides and other components on the surface of the electroplating coating, and can improve the reliability of wires and circuit boards. However, in some cases, the coating adhesion of electroplating equipment is not enough, which will not only affect the service life of electronic products, but also affect the safety of electronic products. Therefore, it is very important to understand the reasons for the insufficient coating adhesion of electroplating equipment.
There are many reasons for insufficient coating adhesion of electroplating equipment, mainly in the following aspects:
1. Poor surface quality of base material
The poor surface quality of the substrate will directly affect the quality of the electrodeposited coating. For example, the existence of such pollutants as grease, dirt, oxide, rust, etc. on the surface will have a negative impact on the quality of the electrodeposited coating, thus affecting the adhesion and appearance quality of the coating. Therefore, the surface must be treated and cleaned before plating the substrate.
2. Insufficient electrolyte concentration
The insufficient concentration of electrolyte is another major factor affecting the coating adhesion of electroplating equipment. If the concentration of electrolyte is too low, the thickness of the coating will be affected, resulting in insufficient adhesion. At this time, it is necessary to increase the concentration of electrolyte to improve the adhesion and appearance quality.
3. The voltage of electronic equipment is unstable
If the voltage of electronic equipment is unstable, the composition of the electrodeposit will be uneven, which is shown by the increase of the coating thickness in the high voltage area and the decrease of the coating thickness in the low voltage area, thus affecting the adhesion of the electrodeposit. Therefore, the stability of voltage should be ensured during the use of electroplating equipment to improve the quality of electroplating layer.
4. Operators are not skilled
The operation of electroplating equipment requires experienced technicians. If the operators are not skilled, it will lead to improper control of electrolyte concentration, temperature, pH and other parameters, thus affecting the coating quality and adhesion. Therefore, operators need professional training to improve their operating skills and abilities to ensure the normal operation of electroplating equipment and high-quality electroplating.
5. The temperature of electrolyte is not well controlled
If the temperature of electrolyte is not well controlled, on the one hand, the evaporation capacity of electrolyte will increase, thus reducing the concentration of electrolyte; On the other hand, it will lead to changes in the composition of the electrolyte, affecting its adhesion and electroplating quality. Therefore, it is a very important measure to control the electrolyte temperature. Temperature controller or water cooling system can be used to control the electrolyte temperature.
In a word, the above are the main reasons that affect the coating adhesion of electroplating equipment. In order to improve the quality and appearance of electroplating coating, it is necessary to control the above factors and strengthen management and maintenance. Only by improving the technical equipment and management measures of electroplating equipment and realizing a good electroplating production process, can the quality and stability of electronic products be better guaranteed.
