The invention discloses an online electroplating carbon treatment system and a carbon tretament method. The carbon treatment system comprises an electroplating bath, a carbon treatment system and a circulating filtration system which are sequentially connected, wherein the carbon tretament system comprises a carbon treatment box and an automatic carbon adding device at the top, an LED illuminationsystem is also arranged at the top of the carbon treatment box, and a catalytic net is arranged inside; the circulating filtration system comprises a first circulating loop formed by connecting the carbon treatment box and a carbon powder filter and used for recovering and circulating carbon powder to the carbon tretament box as well as a second circulating loop formed by connecting the carbon powder filter and the electroplating bath and used for recovering and circulating an electroplating agent to the electroplating bath; the carbon tretament system also comprises an automatic carbon residue discharging system, the automatic carbon residue discharging system comprises a third circulating loop formed by connecting the carbon treatment box and an automatic carbon residue discharging device and used for circulating filtrate to the carbon tretament box, and a carbon residue discharging port is also formed in the automatic carbon residue discharging device. The carbon treatment system is good in treatment effect, convenient and quick to operate and capable of continuously circulating and purifying the agent online.
Description
technical field [0001] The invention relates to an online electroplating carbon treatment system and a carbon treatment method. Background technique [0002] Electroplating is an important process in the PCB manufacturing process, which involves the use of a large number of chemical potions. A large amount of impurities and pollution particles will be brought in during the process of the PCB board going back and forth to each potion tank. At the same time, the electroplating potion itself is in the process of continuous electrolysis Pollution by-products will be produced in the potion. If the pollutants in the potion are not effectively removed over time, the copper plating quality of PCB products will be affected. For the current high-activity electroplating chemicals, such as hole-filling chemicals and pulse chemicals, their tolerance to pollutants is much lower than that of ordinary chemicals, and this type of chemicals puts forward higher requirements for the treatment o...
