Process characteristics:
Renchang semi-bright acidic electroless nickel plating has a long cycle life, up to - one cycle (r), [The meaning of cycle is to plate out all nickel per liter of plating solution and then add it to the nickel when the cylinder is opened. The content is called a cycle, and the minimum coating can be deposited in one cycle]
The highest plating speed can reach -
The loading capacity of the plating solution is large, and it can accommodate up to square decimeters per liter of plating solution for long-term operation and stable performance
Strong deep plating ability and strong throwing ability
High hardness and strong corrosion resistance
Low porosity and no pores in the coating
Good wear resistance, better than electroplating chromium
Good solderability and can be wetted by solder
Good electromagnetic shielding performance, can be used for electronic components and computer hard drives
Performance of electroless nickel plating
Phosphorus content: -Resistivity:
Density: ./3 Melting point: -℃
Hardness: Plated state: -() Bonding force: much higher than after electroplating heat treatment:
Internal stress: The internal stress on steel is lower than
Use Method
This product adopts the internationally accepted three solutions, B and B. Open the cylinder with B and analyze the consumed components of the replenishing working fluid according to the nickel ion concentration. Add with and B. It is extremely convenient:
Cylinder opening method
Take preparing one liter of working fluid as an example

B
The remaining amount is deionized water (conductivity lower than /) and 3. (Adjustment value.)< br/>Temperature: -℃ Loading volume:
The specific method is to first calculate the volume and mark the scale in the tank, fill half of the volume with deionized water, then add and B, and add with deionized water. to a point below the scale line, then use 3. to adjust the value to the scale line, heat to ℃, and then plating according to process requirements.
Operation Points
Make sure the plating tank is soaked in 3) before use and rinsed with water
Keep the temperature of the plating solution at -℃. If the temperature is too low, the speed will be slow, and if the temperature is too high, the plating solution will be Easy to decompose
Use 3. and () to adjust the value and keep the value between. to ensure the plating speed. If the value is too low, the plating speed will be slow. If the value is too high, the plating solution will decompose easily. It is best to use a meter to control it.
Avoid bringing in heavy metal impurities and surfactants
