Socketless technology for enhanced mechanical stability

Whether for a new setup or an existing test fixture, S-Line enables the use of more stable test probes in ICT/FCT and series testing with high test point density.

Design new test fixtures with S-Line

As S-Line does not require an additional receptacle, the grid is determined solely by the diameter of the test probe. This allows you to use more stable test probes in areas with high test point density.

  • Higher mechanical stability
  • Longer service life in series testing
  • Reduced susceptibility to wear

Continue using existing test fixtures

Our socketless test probes and terminals were developed for direct integration into X-Probe®-based test fixtures. This gives you a readily available alternative without complex redesigns or long retrofit times.

  • Compatible with QA X-Probe®
  • No fixture redesign required
  • Simply replace and continue testing

Your X-Probe® alternative in 4 steps

To prevent supply bottlenecks from slowing down your test processes, S-Line enables the fast replacement of common socketless test probes – without redesigning your setup.

Frequently asked questions

S-Line is designed for small grid sizes such as 075, 050, 039 and 031 mil, as well as applications with high test point density. 

Different tip styles and spring forces are available to ensure optimal contact with the test point. 

In addition, E variants with increased spring preload are available for reliably penetrating oxidation and contamination.

Compare S-Line variants

S-Line test probes and terminals can be integrated into all common test fixtures. They were developed for direct integration into X-Probe®-based systems and do not require fixture modifications.

For INGUN test fixtures equipped with standard probes, dedicated S-Line kits are also available. These kits allow existing test fixtures to be converted to socketless technology without requiring a complete fixture redesign.

Depending on the application, the kits consist of two to four fixture plates mounted below the probe plate.

Benefits: 

  • Reduced design and procurement effort 
  • Fast conversion of existing test fixtures 
  • Designed for INGUN MA xxxx and INGUN VA2070S/i3070
