  • Longer MTBA (Mean Time Between Assists)
  • Prolonged Load Board Life
  • Simple Maintenance & Rebuilding
  • Improved OEE (Overall Equipment Efficiency)
  • Lower Overall Cost of Test

Characterization

Pad ROL®100A Contactors are ideal for Manual Device Evaluation, Lab Testing, Prototyping and Characterization

  • Designed to test to 40 GHz.
  • Reliable and repeatable results

  • Robust Manual Actuator life of 10k+ insertions

Pad 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) test 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).


CI – Copper Insert

This insert can be used for optimum grounding and thermal requirements during characterization testing where a device might need to be powered up for an extended period of time to determine steady state performance.
