Production Test

The self-cleaning wipe action of the “rolling contact” design provides many benefits for Production Test:

  • Consistent Contact Resistance
  • Optimized Electrical Performance
  • Higher First Pass Yield
  • Less Frequent Cleaning
  • Increased MTBA (Mean Time Between Assists)
  • Prolonged Load Board Life
  • Simple Maintenance and Rebuilding
  • Typically Backwards Compatibility with Leaded Series 2mm
  • Improved OEE (Overall Equipment Efficiency)
  • Lower Overall Cost of Test


Leaded ROL®200 Contactors are also ideal for Manual Device Evaluation, Lab Testing, Prototyping and  Characterization.

  • Designed to test to 20GHz+
  • Reliable and Repeatable Results
  • Lab Test results correlate to Production Test Floor
  • Robust Manual Actuator Life of 10k+ insertions

Leaded Series Grounding Options

RTH or STH – Contacts in Housing

The standard grounding for most Johnstech contactors utilize contacts, either S-shaped (STH) or ROL® shaped (RTH) contacts configured in the Torlon housing directly beneath the center of the device package ground pad. Johnstech self-cleaning wipe technology provides improved MTBA (mean time between assists) and lower ground inductance.

Insert Technologies

In addition to ground contacts in the contactor housing, Johnstech offers ground inserts that can be removed from the contactor housing itself and interchanged as application requirements change. These ground inserts are used for both grounding and thermal requirements.

RCI or SCI – Contacts in Copper Insert

This insert configuration utilizes multiple contacts in a metal insert to meet the low ground inductance and thermal requirements of the most demanding applications. Available with either S contacts (SCI) or with ROL® contacts (RCI).

Other Grounding Options

Other grounding options are available upon request.
