Advantages Pulse periodic reverse rectifier 25v 5000a
In operation and application, there is almost no difference between pulse reverse plating and DC acid copper system. The main visible difference is rectification. With PPR system, rectifier is controlled by software, and all working methods and batch files can be pre programmed. In addition, like the traditional acid copper system, PPR system also uses whitening agent, carrier and wetting additive system, and can analyze the additive package comprehensively. Traditional acid copper plating also uses two or three maintenance additives.
Pulse reverse current will cause desorption of special additives above the threshold current density. This desorption increases the "resistance" in the high current density (HCD) region, thus increasing the "throwing force" of the electrolyte.
Productivity comparison of existing electroplating production lines.
Compared with the traditional acid copper plating, PPR system uses a lower concentration of copper, thus reducing the amount of sludge generated in the process. Due to the improved method of throwing the coating into the low current density (LCD) area, PPR system needs less time to achieve the minimum copper thickness.
Equipment requirements
The PPR system requires the use of rectifier in square wave form and special cable to avoid inductance. (coaxial cable or twisted pair welding cable is recommended.) Tanks with weirs are also required because pulse plating consumes higher additive rates than DC acid plating.
