Acid copper, nickel acid copper, water-based acid copper, acid copper plating ABS special pay attention to what the problem: the main pre-treatment well, specific steps can be found in other data. Ultrasonic essential surface roughening, electroless deposition of metal used as the conductive layer (refer to the principle plating, particularly the life cycle of the control solution, adding a stabilizer, a complexing agent added regularly recorded attention phosphate control), the bottom copper processing and metal plating, the last is a variety of surface metal plating. . Behind the control methods and hardware is almost, but to do well, management still needs refinement. Once the back-plated ABS, high scrap rate. . Mainly coarsening process will damage the surface state of a part, features. 1. In the broad range of current density, the availability of fast and ultra-high mirror bright leveling, not prone to pinholes and pitting. 2. Plating good ductility, low internal stress of the nickel layer with good adhesion and is ideal for plating. 3. The bath temperature is high, the low current region does not significantly reduce the light intensity and in a short time high light coating. Third, functional additives and chloride ions and control (open cylinder and supplies agent) This brightener for new bath and daily production additions to its major role in the low current region has excellent brightness and leveling (low current region modifier). Coating according to the brightness and leveling, and its consumption of different operating temperature, 50 to 60 ml / time kA. Will be based on the plant operating conditions to determine. (Additive consumption increase with increasing temperature bath) B (open cylinder and supplies agent) This brightener for new bath and supplemented with regular production, its main role in the high current region has excellent light brightness and leveling, to expand the current density range, the coating prevents burning (high current region modifier). Coating in accordance with brightness and leveling their consumption and operating temperature are different, of 40-60 mL / kA time. Will be based on the plant operating conditions to determine. (Additive consumption rises with increasing bath temperature) C (open cylinder agent) only when opening cylinder in the bath and after treatment and the specific carbon large bath with a loss in production use, open cylinder agent is insufficient, The school will make plating current density generated striped deposition; open cylinder coating agent may be combined with excessive force impact. JS-980C can replace part of the JS-980B dosage, the bath has a better dispersion performance. Consumption of 30-60 ml / kA time. Too much too little chloride ion of chlorine ions affect the coating gloss and leveling. -0.1 Optimal concentration range of 0.08 g / liter. The first analysis of local water chloride content, and then adjusted to the optimum range. Necessary to use pure water preparation. When chloride ions will appear too small twigs stripes, excessive influence brightness and low current zone leveling. Dechlorination methods make use of high purity analytical grade zinc. Adding zinc powder will produce hydrogen gas, please pay attention to fire and the use of exhaust facilities. (1) was transferred to pre-pits. (2) The liquid temperature was kept at about 3 O ℃. (3) The amount of zinc powder is added according to the amount of chlorine would be removed, washed with water adjusted to a paste of zinc powder was added with stirring, 1 g of zinc powder can remove about 5 0ppm chloride ions. (4) was stirred for 3 O minutes. (5) Add 5 g / L of activated carbon, stirred for 3 hours. (6) After the standing bath; through the filter to return to the original plating tank.
