Process features
: , PRD aluminum alloy alkaline pre-plating electroless nickel is particularly suitable for aluminum and aluminum alloy pre-plating electroless nickel
b. Reduce pollution in subsequent acidic electroless plating or other electroplating Liquid
, excellent bonding force
, superior in processing complex workpieces
, can also be used as the plating base layer for other substrates
, low operating temperature
Instructions for use
The Pearl River Delta aluminum alloy alkaline electroless nickel pre-plating uses the internationally accepted three solutions, B and B. Open the cylinder with B and analyze the consumed components of the supplementary working fluid according to the nickel ion concentration. Supplementary, extremely convenient:

Preparing the solution:
When opening the cylinder, add the prepared solution/water into the tank.
Add the added B and B, stir evenly mechanically, and filter with a filter.
Add pure water to approximate required volume.
Use ammonia water to adjust the value to . (approximately ml), add water to the scale, and then plating according to process requirements.
