DediProg Introduces UltraConduct™ Rubber Pin Test Socket for AI/HPC Chip Testing
Patented PCR × Pogo Pin Hybrid Structure Delivers Low Contact Resistance, Reliable Contact Performance, and a Cost-Effective Test Interface
August 6, 2026, Taiwan – DediProg Technology, a global leader in IC programming and testing solutions, today announced the launch of its new UltraConduct™ Rubber Pin Test Socket. Featuring DediProg’s patented PCR x Pogo Pin hybrid contact structure, the new solution combines low contact resistance, high-frequency signal integrity, solder ball protection, and long-stroke warpage compensation capability, providing a next-generation test interface for AI/HPC ICs.
"DediProg invested in the development of its own pressure conductive rubber (PCR) several years ago. Leveraging its excellent signal transmission capability and cost-effectiveness, we have continuously expanded the applications of PCR in high-speed testing," said Chong Tsao, General Manager of DediProg Technology. "As testing requirements for large AI chip packages continue to evolve, we launched the UltraConduct™ Rubber Pin Test Socket, which has completed 100,000 contact cycle validation on our in-house production line, delivering a high-performance, reliable, and cost-effective test interface solution for the industry."
UltraConduct™’s Four Core Technologies
- <50mΩ Low Contact Resistance: In high-speed testing environments such as 112G+ (PAM4), conventional spring probe structures may compromise signal integrity due to parasitic inductance effects. UltraConduct™ adopts PCR contact and precisely controls the characteristic impedance of the overall socket structure, achieving contact resistance below 50mΩ while minimizing high-speed signal attenuation and test errors.
- 0.6 mm Long-stroke Design: Featuring a 0.6mm probe compression stroke, UltraConduct™ maintains contact force at 20g with a ±20% tolerance, ensuring reliable contact for large BGA packages while minimizing mechanical stress.
- Flexible, Mark-free Contact: Using a flexible PCR contact interface, UltraConduct™ reduces localized contact stress and leaves no probe marks after testing, preserving solder ball surface integrity while reducing the risk of SMT assembly quality issues and rework costs.
- Wide Temperature Range Testing from -55°C To 150°C: The PCR × Pogo Pin hybrid structure of UltraConduct™ enhances test stability across high and low temperature environments. It can also be integrated with thermal management modules to meet the temperature control and reliability validation requirements of AI/HPC chips operating under high-power conditions.
A New Approach to High-Speed Test Interface Challenges
To address the testing requirements of high-speed signals, high-power chips, and large-package devices, the industry currently uses solutions including ultra-short high-frequency probes, PCR, and coaxial sockets. However, each approach has limitations: ultra-short probes may face mechanical strength challenges, conventional PCR may have limited contact stroke when testing large packages with coplanarity challenges, and coaxial sockets involve higher costs for high pin count applications.
"PCR is an ideal contact interface for high-speed testing, offering low contact resistance and cost-effectiveness. However, maintaining stable contact becomes more challenging when package warpage or solder ball height variations are present," said WeiChu Chen, Operation Director of the IC Test Socket Business Unit at DediProg. "The UltraConduct™ Rubber Pin Test Socket combines the long-stroke capability of spring probes with the low contact resistance advantages of PCR, enabling customers to improve test stability more cost-effectively."
DediProg will showcase the UltraConduct™ Rubber Pin Test Socket and its latest IC test solutions at SEMICON Taiwan 2026, taking place from September 2–4, 2026. Industry partners are invited to visit Booth K2886 at TaiNEX Hall 1 to explore the latest advancements in IC testing technology.
