1. The basic principle of periodic reverse pulse plating
In the pulse plating process, when the current is turned on, the electrochemical polarization increases, the metal ions near the cathode area are fully deposited, and the plating layer is finely crystallized and bright; when the current is turned off, the discharge ions near the cathode area return to the initial concentration. The concentration polarization is eliminated.
Periodic commutation pulse plating is commonly known as double (ie bidirectional) pulse plating. It introduces a set of reverse pulse current after outputting a set of forward pulse current. The forward pulse duration is long and the reverse pulse duration is short. The highly non-uniform anode current distribution caused by the short-time reverse pulse will cause the convex part of the coating to be strongly dissolved and flattened. The typical periodic commutation pulse waveform is shown below.
Features
Using timing control function, the setting is simple and convenient, and the working time of positive and negative current polarity can be arbitrarily set according to the plating process requirements.
It has three working states of automatic cycle commutation, positive and negative, and reverse, and can automatically change the polarity of the output current.
How to install rectifier
This is installation way for remote control rectifier. Not only this way.
1. To connect copper bar with bath/tank
2. To ensure power supply/rectifier is grounded
3. To ensure there is enough water for water cooling type power supply/rectifier
4. We advice that all rectifiers should be isolated to increase of its life.
High frequency switching rectifier, also called switching power supply
A new type of electroplating power supply equipment-high-frequency switching power supply. It combines the advantages of the waveform smoothness of silicon rectifiers and the convenience of voltage regulation of silicon-controlled rectifiers. It has the highest current efficiency (up to 90% or more) and the smallest volume. It is a promising rectifier. The manufacturing technology has solved the power problem, and the high-power switching power supply from thousands of amps to tens of thousands of amps has entered the practical stage of production.
It directly rectifies and filters the AC power grid through the EMI anti-electromagnetic interference line filter, converts the DC voltage into a high-frequency square wave of tens or hundreds of kHz through the converter, isolates and reduces the voltage through the high-frequency transformer, and then through the high Frequency filtering output DC voltage. After sampling, comparing, amplifying and controlling, driving circuit, the duty ratio of the power tube in the converter is controlled to obtain a stable output voltage (or output current).
The adjustment tube of the high-frequency switching rectifier works in the switching state, the power loss is small, the efficiency can reach 75% to 90%, the volume is small, the weight is light, and the accuracy and ripple coefficient are better than the silicon rectifier, which can be in the full output range. Achieve the precision required by production. It has self-protection ability and can start and stop arbitrarily under load. It can be easily connected with a computer, which brings great convenience to automated production and is widely used in the PCB plating industry.
