CCP developed proprietary high-temperature plating test probes — maintaining contact resistance ≤175mΩ at 200°C for 500 continuous hours — a 20× improvement over standard gold plating. Applications include QFN test modules, IC burn-in testing, ATE automatic test equipment, and WLCSP / BGA test socket probes.
Common Challenges
Burn-in testing and IC high-temperature test environments place extreme demands on contact probes — demands that standard gold-plated test probes often cannot meet.
Gold Plating Failure at High Temperature
Standard gold-plated test probes suffer interface diffusion and oxidation within 24 hours at 200°C, causing impedance degradation.
Contact Resistance Degradation
Once impedance exceeds the 175mΩ limit, test failures occur — affecting IC test judgment accuracy and yield.
Frequent Replacement Costs
Short probe lifespan causes frequent downtime for replacement — reducing overall utilization of burn-in test and ATE equipment.
Multi-Package Testing Requirements
QFN, BGA, WLCSP and other package types have widely varying requirements for probe size, pitch, and spring force — demanding custom engineering capability.
