Microwave Base Station Process

Special soak cleaner for aluminum alloy
A. No corrosion effect on aluminum alloy
B. Phosphate free, environmental friendly

Removes dirt & smut formed as by product in the previous processing step.

A. Unique formulation, effectively removes smut and assures adhesion with forthcoming deposit.
B. Unique formulation which ensures eveness and stability of operating solution
C. Ensure uniform appearance of the parts after electroplating.

Forms a layer of evenly distributed Zinc deposit on the aluminum alloy surface.
A. The deposit is a multi-metal codeposit in nature.
B. Ensures excellent adhesion
C. Single component make up, two components additive, improves operation control, lower production cost.

Formation of an active Nickel layer on the Zincates coated aluminum alloy
A. Minimum corrosion effect on Zinc, and prevent oxidation of the thin Zinc layer
B. Improves adhesion between different deposit layers
C. Prolong bath life of the regular Electroless Nickel bath

Covers all the micro pits caused by previous processing steps, improves adhesion between different deposit layers.
A. High density deposit, excellent corrosion resistance
B. Specially formulated stable chemistry, even deposition speed, long bath life.

Specially formulated for plating of communication base station made with aluminum alloy
A. Non-metallic additive, avoid interference of signal by other metal element
B. White, bright, fine, and high purity deposit with (Ag ≧ 99.9%)
C. Uniform thickness of deposit with excellent coverage on recess area.
D. Low contact resistance of deposit, good solderability.
E. Silver concentration of plating solution can be lowered to 10gm / L, lowered the production cost.
Protective coating is formed right after plated parts is dip into this environmental friendly, water soluble working solution.

A. Excellent anti tarnish ability,
B. Negligeable effect on electrical contact resistance of Silver.
C. Negligeable effect on solderability of Silver
D. Excellent wear resistance
E. Coating is non-poisonous, non-irritative, safe and environmental friendly
