Semiconductor test probe components are core precision consumables that ensure the accuracy and reliability of chip electrical performance testing. They are used throughout the entire process, from wafer testing to package testing. Centered around probe card assemblies, this component system achieves precise transmission and acquisition of test signals through direct contact with the chip's fine-pitch pads or solder balls. It effectively safeguards the functional verification and yield control of semiconductor products from bare die to finished goods, representing a key segment within the semiconductor test industry chain that demands high technical expertise and relies heavily on imports.
Semiconductor test probe components are not a single product category but rather a precision manufacturing system deeply integrated with test equipment and processes. In wafer testing, vertical probe card components require micron-level machining precision and high consistency to achieve non-destructive contact and high-frequency signal transmission for ultra-fine pitch chip pads. In package testing, spring probe components must maintain stable contact resistance and mechanical durability through hundreds of thousands of pressure cycles. Supporting micro-components such as plungers, barrels, and springs work in coordination with test software systems to collectively support the intelligent and highly reliable testing needs throughout the entire semiconductor manufacturing process.
In 2020, the overall market size for semiconductor test probe components in China was 6.9 billion RMB. The total market experienced rapid growth in subsequent years, reaching 11.3 billion RMB in 2024. Within this, the market for package test probe components grew from 5.6 billion RMB to 9.9 billion RMB, while the wafer test probe components market increased from 1.3 billion RMB to 1.4 billion RMB. The growth rate is expected to further accelerate between 2025 and 2029, with the Chinese market size for semiconductor test probe components projected to reach 37.9 billion RMB by 2029.
