Custom High-Precision Probe Blocks & Test Fixtures (BGA, QFN, SOM)

High-Density Interconnect Solutions for ATE, ICT, and Functional Testing

1. Interface Probe Blocks (Pogo Towers)

JIANYANG (JYPROBE) specializes in high-performance interface blocks designed to bridge the gap between test boards and translation boards—acting as the critical "Pogo Tower" for semiconductor test environments. Our blocks are engineered for ATE fixtures, delivering superior signal integrity in both In-Circuit Test (ICT) and Functional Test (FCT) applications.

Optimized Signal Integrity: Our standard 128-pin and 256-pin configurations are optimized to minimize contact resistance, ensuring stable electrical performance in high-speed environments.

Space-Efficient Modular Design: The adjustable assembly method allows fixture houses to significantly reduce the overall footprint of the test system.

Ultra-Fine Pitch Capability: Supporting high-density requirements with precision machining down to 0.27mm, 0.35mm, and 0.50mm.

Premium Engineering Materials: We utilize Ceramic Peek, PEEK, Torlon, and Ultem (PEI) to ensure maximum thermal and dimensional stability for RF Testing, Burn-in, and System-level Test (SLT).

2. Signal Contact Probe Blocks (40GHz+ & RF)

JY Electronics (JYPROBE) designs and manufactures high-frequency signal contact blocks specifically for FPC connectors and Radio Frequency (RF) applications. We focus on low-loss, high-density interconnect solutions for next-generation telecommunications and Automated Test Equipment (ATE).

Frequency Range: Expertly engineered for signals exceeding 40GHz.

Low Insertion Loss: Designed for lower compression force to protect delicate DUTs while maintaining high-speed signal fidelity.

Precision for FPC: Specialized solutions for fine-pitch flexible printed circuit (FPC) testing with minimal signal crosstalk.
