Why purify?
1. During the use of electroplating solution, organic by-products continue to accumulate
2. TOC (Total Organic Pollution Value) continues to rise, which will lead to an increase in the amount of electroplating brightener and leveling agent added
3. Defects in the electroplated copper lattice
4. Reduce the physical properties of the electroplated copper layer
5. Reduce the thermal reliability of PCB finished boards
6. Decreased deep plating ability
Traditional carbon treatment method for electroplating process
1. Long operation process and long time (more than 4 days)
2. Large loss of plating solution
3. The lost electroplating solution requires wastewater treatment, which increases the cost of wastewater treatment
4. The carbon treatment equipment occupies a large area, more than 40 square meters of space, and the treatment tank is huge
5. High energy consumption, heating treatment is required in the carbon treatment process
6. The operating environment is harsh! High temperature operation, pungent reagents, dusty, heavy workload
7. Poor effect
A potion with a TOC original value higher than 3000ppm can only reduce 500ppm-900ppm! Based on 10,000 liters of potion, the cost of traditional carbon treatment including materials, waste water, labor, and loss of production capacity will cost as much as 180,000!
Advantages of the new syrup purification system
01
Short processing time, increase productivity
Taking 10,000 liters of potion as an example, the processing time takes about 12 hours, which only consumes 1/8 of the time of traditional carbon processing. The time saved can produce more high-quality products and increase productivity.
02
Zero discharge of wastewater, energy saving and emission reduction
The system adopts an online continuous cycle purification method to remove organic pollutants in the potion. This process does not require pure water or heating, and truly achieves the goal of energy saving and emission reduction.
03
Simple equipment and small footprint
The new syrup purification system is an online processing system, no additional carbon processing tank is needed, and the device has a small footprint.
04
Simple operation, improve construction environment
The system is an automated device that is simple for personnel to operate and easy to use; and adopts a closed feeding method to prevent dust from flying in the sky, improve the working environment of on-site construction personnel, and reduce occupational health risks.
05
Strong pertinence, high removal rate of organic pollutants
Under normal temperature conditions, the modified adsorption material is used to efficiently adsorb various organic by-products of electroplating additives in the syrup, retain the effective additives to the greatest extent, and do not need to add any chemical agents. It is purely physical and does not need to worry about introducing other impurities ; The original TOC value of the potion is higher than 3000ppm, it can be reduced by more than 1500ppm.
