High-Precision Beryllium Copper (BeCu) Probe
Low Contact Resistance, Customizable Tips, Gold/Nickel/Silver Plating
Beryllium Copper (BeCu) probes are engineered for high-precision electronic testing, offering low and stable contact resistance for accurate measurements. The soft BeCu tip reduces surface damage, making it ideal for sensitive device pads. The probe's self-polishing action maintains a clean contact surface, ensuring reliable performance throughout its service life. Customization options include various tip geometries, plating materials, and bend angles to suit your specific testing needs.
