Gain access to a comprehensive range of high-quality products that will enhance precision and accuracy in the semiconductor test industry and are the ideal solution for fine-pitch applications and advanced packaging such as CSP, BGA, SiP, SoC, flex-circuits, and micro PCBs.
As a worldwide ICT/FCT probes manufacturer, we take pride in offering high-quality products designed to meet the unique needs of our customers. We can also help design fixtures or sockets for your testing needs.
The unique construction of our microHELIX probes allow for tighter pitch and closer centers, ensuring reliable contact in sockets, fixtures, and contactors for semiconductor testing and coaxial installations. With center-to-center spacing down to a tenth of an inch or a quarter of a millimeter (.010" or .254mm), our microprobes are specifically engineered to meet the industry's stringent requirements.
Our pogo pins are designed to be used with a probe guide, eliminating the need for solder and simplifying the testing process. This convenient and efficient solution saves time and effort and allows seamless integration into your testing setup.
While we showcase just a few configurations below, our expert team understands that every application has unique requirements. If you don't find the size or configuration that fits your needs, simply reach out to us. We are eager to collaborate with you and customize the perfect solution for your needs.
Contact us to learn more about our made-in-the-USA products and discover how our precision testing solutions can elevate your performance in fine-pitch applications.
The unique construction of our micro-HELIX test probes enables tighter pitch, closer centers, reduced crosstalk (below that achieved with traditional spring loaded test probes), thereby ensuring precise electrical contact every time. Say goodbye to inconsistent readings and unreliable tests.
Our micro-HELIX probes are built to withstand the rigorous demands of semiconductor testing. With robust materials and meticulous craftsmanship, our test probes provide long-lasting performance and reduce the need for frequent replacements.
With micro-HELIX test probes, you can achieve faster and more efficient in-circuit testing (ICT) and functional circuit testing (FCT). Boost productivity and streamline your operations with our advanced testing solutions.
We understand the diverse requirements of our clients, which is why we offer a range of micro-HELIX probe series, the S200, S300, S400, and S500 series. The variety allows for seamless integration into sockets, fixtures, and contactors, catering to your specific testing setup.
When precision and reliability matter, trust AlphaTest Corporation to deliver unmatched solutions. Our microHELIX test probes and test fixtures set the benchmark for excellence in semiconductor testing. Experience enhanced accuracy, efficiency, and durability like never before.
