electroless copper plating process

120-H High-performance acid brightening copper plating process

 

Applications and advantages

  • Excellent brightening and leveling;
  • Good covering, good leveling in LCD area, no pinhole and hard spots;
  • The bath solution is stable and easy to control;
  • The plating layer has good flexility, low electrical resistivity, so fits into the electrical machine industry which has high requirements in physical property of the deposit.
  • Could be implemented in various metal, such as iron, brass and zinc alloy parts, as well as plastics.
  • Has a good impurity tolerance and can be used for a long time, activated carbon is needed under 800-1000 Ah/L quantity of electricity.

 

Bath Composition and Working Conditions

 

Bath composition and working conditions Range Standard
Cupric sulfate (CuSO4·5H2O) 180-240g/L 200g/L
Sulphuric acid (H2SO4) 50-80g/L 60g/L
Chloride ion (Cl-) 60-120mg/L 80mg/L
Make up solution 120-H Mu 4-6ml/L 5ml/L
Brightener 120-H A 0.4-0.6ml/L 0.5ml/L
Brightener 120-H B 0.4-0.6ml/L 0.5ml/L
Temperature 16-30℃ 20-28℃
Cathode current density 1-6A/dm2 3-5A/dm2
Anode current density 0.5-3 A/dm2
Anode Phosphorous copper anode (0.03-0.06% phosphorous)
Agitation Air agitation or mechanical agitation
 

 

Functions of additives

 

  • Make up solution 120-H Mu: A lack of Make up solution 120-H Mu would lead to strips in high and low current density areas in deposit. Too much 120-H Mu would make deposit misty. Make up solution 120-H Mu contains proper amount of Brightener 120-HB and wetting agent.
  • Brightener 120-H A: A lack of Brightener 120-H A would decrease the leveling in whole current density areas. Too much 120-H A would engender pinholes on the layers. The low-current density area has poor leveling and has patent boundary against the layer of other areas, but it remains bright.
  • Brightener 120-H B: A shortage of Brightener 120-H B would lead to burning in high current density area of the deposit. Too much 120-H B would make deposit misty and also lead to poor brightening in low-current density area.

 

Preparation of bath solution

  1. Infuse half amount of deionized water into the bath (or spare bath). The chloride ion content of the deionized water should be below 70mg/L (ppm).
  2. Add the required amount of sulphuric acid very slowly. A large amount of heat would generate. Stir strongly and add slowly to make the temperature below 60 (Attention: be careful while adding sulphuric acid. Wear protective clothes, gloves and eye shield to ensure safety).
  3. Add required amount of cupric sulfate, stir until it is dissolved.
  4. Add 2g/L activated carbon powder and stir for at least 1 hour.
  5. Use the filtration pump to filter the solution into a clean electroplating bath. Add required amount of pure water.
  6. Cool the bath solution to 25.
  7. Find out the content of chlorine ion through analysis. Add proper amount of hydrochloric acid or sodium chloride if needed to make the content of chloride ion be within the standard range.
  8. Add proper amount of 120-H additives and stir.
  9. Electrolyze the bath solution for 2Ah/L. Then it could be put into production.

 

Packing and Storage

 

Packed in 25kg plastic drums, stored in cool and dry place.
