  Probe Spring Construction
   

QA Technology probes are available in a wide range of spring forces allowing the Test Engineer or Fixture Fabricator to custom-tune test probe applications.

Spring design is a critical factor in probe life, internal resistance and contact integrity. QA springs are force and cycle tested to insure consistent performance and reliability.

Low force springs are typically used in highly populated sections of vacuum fixtures for proper pull down. Standard force springs are ideal for most vacuum and mechanical fixtures. High force springs are useful in penetrating contaminated contact surfaces in low-density areas. Elevated, Extra-high and Ultra-high force springs are used in cases of extreme contamination or heavy flux residues.

Increased available space for the spring in our patented probes allow QA to offer the only .100 [2.54] center spacing .250 [6.35] stroke probe that can be used at full stroke without risk of fatigue failure. This extra space also allows us to offer .400 [10.16] probes which fit in the same sockets as their .250 [6.35] stroke counterparts.

For ease of selection and to help identify the proper replacement probe, the probe tubes on our 075-25, 100-12, 100-15, 100-16, 100-24, 100-40, 125-PRH25 series probes, as well as our X50-25, X50-40, X75-25 and X75-40 X Probe Socketless series are marked with spring force designations on their outer surface.
