High-Current SMT Contact Pads: 6A Rated, 0.15mΩ Max Resistance
Jiatel’s Gold Plated Contact Pads (also known as Pogo Pin Targets or SMT Surface Mount Contacts) are engineered to provide a stable, low-resistance interface for spring-loaded connectors. Designed for high-frequency mating, our pads feature premium C3604 Brass or Beryllium Copper with precision Gold plating (up to 30u”), ensuring over 100,000 cycles of reliable connectivity.
🚀 Why 0.15mΩ Max Resistance Matters:
In 5G and fast-charging applications, high resistance causes heat. Our precision CNC machining and 3u” minimum gold plating ensure maximum thermal efficiency and zero signal drop-out.

Frequently Asked Questions (FAQ)
- Q: Why is gold plating essential for pogo pin contact pads?
A: Gold provides superior conductivity and oxidation resistance. Jiatel’s controlled plating thickness ensures the contact resistance remains low even after thousands of cycles. - Q: Can you provide contact pads in custom shapes?
A: Yes, we specialize in CNC and stamping for square, circular, and even concave pads designed to center the pogo pin plunger. - Q: Why is the 0.15mΩ contact resistance significant for my design?
A: In high-current applications (up to 6A), even minor resistance can lead to significant heat buildup and power loss. Our precision-machined pads ensure superior thermal management and stable power delivery. - Q: What is the standard seating height of Jiatel SMT contact pads above the PCB?
A: Our standard low-profile contact pads sit 0.10mm above the PCB surface, optimized for high-density SMT assemblies while saving vertical space. - Q: Are these contact pads compatible with automated SMT reflow soldering?
A: Absolutely. They are engineered to withstand lead-free reflow soldering temperatures of up to 260°C for 10 seconds without discoloration or deformation. - Q: Can I request custom shapes or 3D technical documentation?
A: Yes. We offer full DFM support for custom shapes to fit your specific PCB layout. Technical datasheets and 3D STEP files are available to help accelerate your CAD design process.
