Product Overview

Beryllium copper probes use a beryllium copper alloy base material and undergo heat treatment strengthening + precision forming + surface gold plating. They are miniature elastic electrical contact components that combine high elasticity, high conductivity, and fatigue resistance, support micron-level precision machining, and are widely used in endoscopes, minimally invasive instruments, FPC, and micro modules for signal conduction and electrical testing. Tip shape, outer diameter, length, and spring force can be customized to non-standard specifications.

Core Materials

• Base material: beryllium copper (BeCu), age-hardened, with a high elastic limit, resistance to metal fatigue, low magnetic properties, and good resistance to body fluid corrosion

• Plating: nickel base layer, gold surface layer (hard gold / soft gold optional), reducing contact resistance, providing oxidation resistance and wear resistance, and improving stability under repeated contact

Core Product Advantages

• Excellent elasticity and fatigue resistance: no deformation after hundreds of thousands of reciprocating contacts, stable spring force, suitable for repeated-motion contacts in endoscope bending sections.

• Low contact resistance: the gold plating ensures stable signal transmission and no signal loss during weak electrical signal acquisition.

• Precision micromachining: supports ultra-fine outer diameters and special-shaped tips (conical, round, flat, serrated), meeting assembly needs in tight spaces.

• Corrosion resistance: medical-grade surface treatment, resistant to saline and human body fluids, suitable for minimally invasive medical devices.

• Non-magnetic: non-magnetic properties, compatible with MRI ancillary instrument scenarios.

• Customizable: dimensions, tip style, spring force, and plating thickness can all be custom-tooled on demand .
