The “rolling contact” design of the ROL® Contactor, which creates a self-cleaning wipe action, provides extensive Production Test benefits:
- Consistent Contact Resistance
- Optimized Electrical Performance
- Higher First Pass Yield
- Repeatable Site-to-Site Performance
- Longer MTBA (Mean Time Between Assists)
- Prolonged Load Board Life
- Simple Maintenance & Rebuilding
- Improved OEE (Overall Equipment Efficiency)
- Lower Overall Cost of Test
ROL®200 Contactors are ideal for Manual Device Evaluation, Lab Testing, Prototyping and Characterization.
- Designed to test to 20 GHz.
- Reliable and repeatable results
- Lab Performance correlates to Production Test Floor
- 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.
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.
EI Insert – Eco™-1 Insert for 3×3 QFN Pad Packages
The EI Insert is available in 3×3 mm package sizes for Pad ROL®200 Series and Pad Series 2mm test contactors. The high-strength ECO™-1 material provides long-life. The elastomer-based design provides excellent retention in the housing and preload bias to the load board for robust performance.
EI Insert – Eco™-1 Insert for 4×4 QFN Pad Packages
The EI Insert is available in 4×4 mm package sizes for Pad ROL®200 Series and Pad Series 2mm test contactors. The high-strength ECO™-1 material provides long-life. The elastomer-based design provides excellent retention in the housing and preload bias to the load board for robust performance.
