In modern semiconductor testing, the Test Socket PCB for IC is a critical interface between the device under test (DUT) and Automated Test Equipment (ATE). These PCBs enable accurate electrical contact, high-speed signal transmission, and mechanical stability, ensuring reliable IC, memory, and RF testing.
As integrated circuits become more complex with higher pin counts, finer pitch, and faster data rates, the role of the test socket PCB has become increasingly important. A high-quality Test Socket PCB for IC ensures repeatable test results, signal integrity, and long-term durability, directly impacting test yield and semiconductor production efficiency.
Key Features of Test Socket PCBs for ICs
-
High-Density and High Pin Count Design
Supports ICs with hundreds or thousands of pins, using fine-line routing and HDI technology to maintain signal integrity. -
Controlled Impedance for High-Speed Signals
Ensures accurate digital, analog, and RF testing by minimizing crosstalk, signal reflections, and timing errors. -
Mechanical Precision and Reliability
Maintains consistent probe alignment and contact force across thousands of test cycles, reducing failure risks. -
Multilayer and Rigid-Flex PCB Options
Optimized stackups separate signal, power, and ground planes to improve isolation and reduce noise. -
