  Probe Construction

Materials and methods used in the manufacture of all QA Technology test probes meet only the highest standards. Each component is designed, manufactured, assembled and inspected for optimum performance. This assures superior quality for every product.

"QA" stands for Quality Assurance in every test probe and socket we manufacture.   Springs are constructed of high-strength music wire or stainless steel for long life.   Plungers are manufactured from beryllium copper or steel, heat treated and plated gold over nickel.  
Probe tubes are deep-drawn from a variety of alloys and feature hardened precious metal cladding for high performance.   Our patented probe design features an angled plunger tail for improved biasing that ensures consistent contact with the probe tube.   We offer a wide variety of point styles to suit virtually any test requirement.
