FAQs

 Yes, we specialize in fully custom pogo pin solutions, including size, shape, current rating, plating, and connector configuration, tailored to your project requirements.

All quotes are valid for 30 days from the issue date. Prices may be adjusted for orders placed after this period due to material cost fluctuations.

Simply send us your design drawings, specifications, quantity, and any special requirements, and we will provide a detailed, no-obligation quote within 24 hours.

Changes can be made before production starts. Once mass production begins, modifications may incur additional fees and extend the lead time.

 Yes, we welcome trial orders to help you test our product quality before committing to large-scale production.

For standard in-stock pogo pins, the MOQ is flexible (low MOQ available for small orders). For custom pogo pins, the MOQ is typically 500-1000 pieces, depending on the complexity of the design.

 Absolutely. We will provide regular production updates and photos/videos of your order at key stages, and share the tracking number once the shipment is dispatched.

ustom pogo pin production typically takes 7-15 business days after sample approval and deposit payment. Rush orders are available upon request, please contact our sales team for priority processing.

The probe selection must match the center-to-center distance of your test points. For a standard 2.54mm pitch, our 100-series probes (e.g., SF-PA100) are recommended. For fine-pitch applications (below 0.5mm), we offer miniaturized semiconductor probes designed for high-density PCB architectures.   

Gold plating offers superior chemical stability and electrical conductivity. It prevents oxidation, ensuring stable, low contact resistance over millions of cycles, even in harsh environments. We offer customizable plating thicknesses (e.g., 2μ" to 10μ") based on your specific wear and conductivity requirements.   

SFENG High Current Probes are engineered for battery  testing, capable of carrying sustained loads up to 1000A. By utilizing Beryllium Copper (BeCu) and specialized gold plating, we maintain contact resistance below 1mΩ, minimizing heat generation during high-power validation.
