Medium Phosphorus Electroless Nickel Process ; FFI-7880 is a stable, fast, bright electroless nickel process
FFI-7880 is a stable, fast, bright electroless nickel process. This process has many advantages such as high temperature stability, strong anti-pollution ability , good coverage under low load and low operating costs. FFI-7880plates fast and the deposition rate is stable, under normal operating conditions, the deposition rate can be controlled stabilized at 15 ~ 20μm / hr, phosphorus content is controlled at 6-8%. The process generates a dense layer of nickel, combined with the FFI-7890 Chemical gold,the binding force and weldability are excellent.
1 Process Features
High bath stability, long life
Easy activation, deposition speed, deposition rate stability;
Good coverage under low load
High hardness, good abrasion resistance
Plating smooth and bright, with good weldability, do not attack the dry and the barrier layer, can effectively eliminate the black pad and other quality problems.
