PAD SERIES 1MM
EVALUATION SOCKET
For QFN, DFN and Other
JEDEC-MO-220 and -229
Pad-Style Applications
Johnstech's Pad Series 1mm Evaluation Socket
was developed specifically for low volume,
Manual (non-automated) Test environments.
It provides a high performing, low cost solution
for the testing of high-frequency, high-power
devices in the Prototyping, Characterization
and Evaluation phases of your product development
process.
Ideal for:
• QA Testing
• In-Circut Testing
• Demo Boards
• Bench Top Testing
• Reliability Testing
• Evaluation Boards
Self Cleaning
Contacts
The Pad Series 1mm Evaluation Socket utilizes
Johnstech’s patented ROL technology for superior
electrical performance. The self-cleaning wipe
action of the “rolling contact” motion breaks
through oxide buildup for a clean connection to
the pads. With built-in alignment features and a
single piece housing, the 1mm Evaluation Socket
outperforms other contacting technologies.

• Designed to test to 40+GHz.
• Proven mechanical reliability on both exposed
and/or recessed pads.
• Bolt-down socket provides near solder-down
performance without the cost, time or hassle of
soldering chips directly to test boards.
• Consistent contact resistance optimizes
electrical performance.
• Clip-on Manual Actuator, Contacts, Elastomers
and Housing life of 1,000+ insertions.
