Workshop Overview
The CYMBER electroplating workshop covers an area of approximately 1,000 square meters and specializes in surface treatment of high-precision CNC-machined components and high-end connector parts. It currently operates two independent production lines: one manual hot-dip silver plating line and one fully automated electroless nickel plating line designed specifically for small precision parts. The two lines operate independently, allowing flexible scheduling according to customers’ requirements for conductivity, corrosion resistance, and solderability.
Hot-Dip Silver Plating Process
This dedicated process serves large copper busbars, power terminals, and other heavy copper substrates requiring superior conductivity and bonding strength.
Process flow:
● Pre-treatment: chemical degreasing → rinsing → acid activation → ultrasonic cleaning → DI water rinsing
● Flux coating: immersion in proprietary flux to form a uniform flux film and prevent bare spots
● Pure silver hot dipping: 99.99% silver is melted in dedicated graphite crucibles and maintained in liquid state; workpieces are manually immersed with precise control of dipping time (typically 3–8 seconds) to achieve controlled silver thickness (standard 5–25 μm, adjustable per drawing)
● Post-treatment: high-speed centrifugal silver removal → anti-tarnish passivation → DI water rinsing → hot air drying
Key advantages:
● Dense crystalline silver layer with metallurgical bonding to copper substrate, delivering exceptional adhesion
● Extremely low contact resistance (<0.1 mΩ), ideal for high-current applications
● Particularly suitable for components that require subsequent high-temperature brazing or crimping
Automated Electroless Nickel Plating for Precision Small Parts
This fully automated barrel/hanging line is dedicated to small and complex CNC parts such as connector pins, shielding covers, RF components, etc.
Process flow:
● Pre-treatment: multi-stage degreasing → micro-etching → activation → DI water rinsing
● Electroless nickel plating: parts are hung on customized fixtures and processed in sealed plating modules; medium-phosphorus chemistry (8–10% P) is used, with typical thickness of 6–12 μm (3–25 μm available on request)
● Post-treatment: multi-stage DI water rinsing → hot DI water immersion → drying → unloading
Key advantages:
● Outstanding thickness uniformity even on sharp edges, recesses, and blind holes
● Excellent corrosion resistance (>480 hours neutral salt spray)
● High as-plated hardness (550–650 HV; >1000 HV after heat treatment)
● No current density distribution issues, making it ideal for geometrically complex micro parts
Overall Workshop Capabilities and Quality Control
● Combined daily capacity of both lines reaches 80,000–100,000 pieces (depending on part size)
● On-site wastewater treatment plant with tertiary treatment and heavy-metal resin adsorption ensures compliant discharge
● Environmentally controlled facility maintains stable temperature and humidity to guarantee process consistency
The CYMBER electroplating workshop serves leading customers in power, new energy, telecommunications, and industrial automation sectors with stable processes and highly reliable coatings. We let measurable layer performance and traceable quality records speak for themselves.
