Fine-pitch – precision in high-current contacting
Maximum performance in minimum space
In the world of modern electronics, everything is getting smaller – except the performance requirements. This is where the fine-pitch contacting solutions from FIXTEST set new standards. They combine the best of both worlds: maximum current-carrying capacity and extremely small pitch sizes – now also available in Germany.
Our USP: Fine-pitch down to 0.1 mm
FIXTEST is the only supplier in Europe offering high-current spring contact probes in the fine-pitch range down to 0.1 mm pitch – developed by a highly specialized team of just 22 employees.
Our solutions are specifically designed for applications where high current density meets minimal space, such as power ICs, EV modules, AI chips, mobile devices, or modern semiconductor packages.
Innovation and adaptability in fine-pitch contacting
Every fine-pitch contacting application has its own specific requirements for precision, durability, and signal integrity. That’s why FIXTEST develops not only standard solutions but also customized contacting concepts precisely tailored to your test environment.
From selecting the right materials and defining the optimal spring force to integrating the contact into complex test systems – our engineering team supports you from concept to series production.
This ensures that your fine-pitch solutions meet the highest standards – today and in the future.
