Leaded ROL® 400

The Leaded ROL®400 has incorporated Johnstech's patented ROL® technology to provide excellent electrical performance and proven mechanical reliability for leaded devices. The ROL® technology is ideally suited for high volume production testing and it is also offered in two Contact configurations developed specifically for the unique challenges and different device platings used in Lead-Free Testing.

Production Test

The “rolling contact” design of the Leaded ROL®400 Contactor is especially well-suited to Production test providing:

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

Characterization

Johnstech Contactors are unsurpassed for Manual Device Evaluation, Lab Testing, Prototyping, and Characterization

  • Designed to test to 5.4GHz.
  • Reliable and Repeatable Results.
  • Lab performance correlates 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.
