To meet the charging interface requirements of smartwatches, smart bands, and AI glasses, CCP provides three high-volume solutions: 1.25mm ultra-low height, low contact resistance 95mΩ, and APT electrolytic & chemical plating resistance. These cover sweat resistance, salt spray resistance, and cosmetic electrolytic corrosion resistance, complying with nickel release standards.
Common Challenges
Wearable devices are worn close to the body for extended periods and operate in extremely space-constrained environments, demanding charging interfaces that are compact, low-resistance, and corrosion-resistant.
Space-Constrained
Smart band bodies are extremely thin, making it difficult to find Pogo Pins that can be mass-produced at a total height under 1.25mm while maintaining stable contact force.
Contact Resistance Control
Standard SUS316F stainless steel contact resistance is 113.5mΩ, which cannot meet the demands for high-efficiency fast charging and low heat generation; furthermore, traditional materials cannot comply with nickel release regulations.
Sweat & Salt Spray Corrosion
Smartwatches and bands are in prolonged contact with sweat and must pass 168H+ salt spray and sweat tests, with contact resistance that must not degrade due to corrosion.
Electrolytic Corrosion (Cosmetics)
AI glasses and wearable devices are in prolonged contact with cosmetics and sweat; standard 50μ gold plating withstands electrolytic corrosion for <1 min, far below the OEM requirement of >60 min.
CCP Capabilities
In response to the four major wearables charging challenges, CCP provides corresponding self-developed pin body structure, alloy materials, and proprietary plating technologies.
1.25mm Ultra-Low Height
Self-developed pin body structure with redesigned internal spring geometry, achieving the smallest mass-producible Pogo Pin in CCP’s product lineup (total height 1.25mm).
VH3 Low-Resistance Alloy
Proprietary stainless steel alloy with 95mΩ contact resistance at 80g contact force (vs SUS316F 113.5mΩ, a 16% reduction).
APT Electrolytic & Chemical Plating Resistance
Advanced Plating Technology dual-function plating: electrolytic corrosion resistance >60min (standard gold plating <1min), salt spray/sweat resistance >168H.
Wearables Safety Compliance
Both VH3 alloy and APT plating comply with nickel release regulations and can directly pass OEM human-contact safety certification for wearable devices.
