Semiconductor packaging, 5G high-frequency communication and precision medical electronics require ultra-precision testing components with high stability and signal integrity. Ultra-fine pad chips, miniature sensor modules and compact medical circuit boards demand tiny-tip, low-interference spring probes to complete accurate contact testing.
As a professional threaded test probe pin supplier china, SFENG provides high-precision threaded probes, switch probes and fixed-type test pins specially designed for precision fixture assembly and high-precision medical testing scenarios. Our precision spring probes adopt beryllium copper and high-carbon steel materials with multi-layer gold-plated treatment, providing outstanding electrical conductivity, wear resistance and corrosion resistance.
Custom ultra-fine tip structures adapt to pad pitches below 40μm, perfectly meeting wafer-level testing, chip packaging testing and high-frequency signal testing requirements. In medical electronic testing scenarios, our high-stability threaded probes ensure consistent low-resistance contact for portable medical detectors and precision medical control boards. All products comply with ISO9001 quality certification, with excellent batch consistency and long service life. Supported by professional R&D capabilities, we provide reliable precision testing solutions for global semiconductor and medical electronic manufacturers.
