Electroplating rectifier greenization:

Electroplating rectifier system greenization have profound meaning:
The first is significant energy-saving, which means save power generation capacity, while power generation is an important cause of environmental pollution, so power saving can reduce environmental pollution; and secondly these power can not (or less) generates pollution to power grid, International Electrotechnical Commission (IEC) has developed a series of standards such as IEC555, IEC917, IECl000. In fact, many power electronic energy-saving equipment, often turn into sources of pollution on the grid: inject to grid of serious harmonic current, make the total power factor drops, so many glitches coupling grid voltage spikes and peaks, even chipping and distortion. In end of 20th century, a variety of active filter and active compensator was born, with a variety of power factor correction method. Laid the foundation for mass production of a variety of green switching power supply in 21 century.

Modern power electronics technology is the basis for development of electroplating rectifier:

Modern power electronics is the basis for development of electroplating rectifier technology. With the continuous emergence of new power electronic devices and adapted to more higher switching frequency circuit topology, modern power supply technology driven by real needs will be rapid developped. In traditional application technique, due to the performance limits of power leaving, switching power supply device performance is affected. Greatly put to good use of characteristics of various power devices, minimize device performance impact on switching mode rectifier, new power circuit topology and new control technology enables power switching at zero voltage or zero current state, which can greatly increase the operating frequency, improve work efficiency of switching mode power supply, then design excellent performance switch mode power supply.

More electroplating rectifier waiting to be developed:

In short, power electronics and switching electroplating rectifier technology continues to move forward due to application requirements, the emergence of new technologies will make many applications replacement products, but also to open up more and new applications. High frequency rectifier switching power supply, modular, digital, greenization etc., will mark these technologies as mature, to realize high efficiency and high-quality electricity application combined. In recent years, with the development of the communications industry, switch power technology as the core of communications switching power supply, only the domestic market demand of more than 20 billion yuan, has attracted a large number of scientific and technical personnel to develop research. Switching power supply instead of linear power and phase control power supply is the trend and will soon be developed. There are many other in switching power supply technology as the core of a dedicated power supply, industrial power are waiting for people to develop.

Copper plating line process:

Electroless copper plating line is a process for printed circuit board manufacturing, often called sink-copper or PTH, which is a self-catalytic redox reactions. First treatment with activator agent, adsorbed on insulating substrate layer surface of active particles usually as metal palladium particles (palladium is a very expensive metal, the price is high and has been rising, to reduce cost now practical colloidal copper process is in the application), copper ions are first reduced on these active palladium metal particle, which these reduced metal copper nuclei itself has become a copper ion catalyst layer, so that copper reduction proceed on these new copper nuclei surfaces.

Electroless copper plating: traditional copper plating mostly as vertical lines, process are similar, the general process is:
Cleaning → Neutralization → Degreasing → Microetching → Pre-ditching → Activation → Chemical copper plating.

The main components are cathode and anode in copper plating line:

Cathode: giving rise to the starting & end a couple of stainless steel rod having a pair of electrical contact ring, copper brush is pressed against the copper ring in order to get good contact, connected to the negative pole of rectifiers. By retaining roller, the cathode cut off contact with plating solution.
Copper plating line anode: 2 titanium plate installed in plating bath, these two anode pieces connect with positive rectifies pole by electricity cable directly. Anode soaked in chemical plating solution.

Chemical copper plating line principle:

Electroless copper plating on the surface of the catalytic activity by the action of a reducing agent to precipitate the copper ions reduced:
Reduction (cathode) reactions: CuL2 + + 2e- → Cu + L
Oxide (anode) reaction: R → O + 2e-
Thus, with hypophosphite as a reducing agent for chemical copper plating main reaction is: 2H2PO2- + Cu2 + + 2OH- → Cu + 2H2PO3 + H2 ↑
In addition to the establishment of the thermodynamics, chemical reactions must also meet dynamics conditions. Like other chemical copper as the catalytic reaction thermal energy is required to cause a reaction, which is why only when the chemical bath plating deposition get speed plating under certain temperature. Theoretically copper plating speed to express by increasing the concentration of the reaction product of reactant concentrations and reduce the speed. In actual use, the electroless copper plating solution containing certain additives, its have too many factors to effect, the situation becomes too complicated. Thus, most of the electroless copper plating dynamics research is limited to the most basic component of the bath at the start.
