Johnstech International
Pad ROL™200K (Kelvin) Series Test Contactor
For QFN, DFN, and Other Pad-Style Applications
Ultimate Performance. Configurable Design.
The Johnstech Pad ROL™ 200K Series configurable Contactor is the ultimate high performance engineering and production Kelvin solution. Ideal for high power and precision analog devices that require very tight test guard-bands, this Kelvin solution delivers unprecedented mechanical and electrical performance, flexibility and value.
Solid Force Contact and Dual Touch
Sense Design
The Pad ROL™200K guarantees a perfect, high current, low resistance connection every time. Its design is a unique combination of our traditional high current solid Pad ROL™ 200 Contact (the Force) and a dual touch, flexible Sense Contact that surrounds the Force on both sides. This design ensures a good Kelvin connection regardless of device variations.
Self Cleaning Wipe Action
Two self cleaning features ensure that the Pad ROL™200K delivers the lowest and most repeatable Kelvin contact resistance available on the market today. The Force Contacts include the oxide removal wipe action of Johnstech's patented ROL™ technology, which automatically prevents surface debris build-up on the Contact tip. In addition, the Force and Sense work in combination to remove debris between the two Contacts. These inherent wipe functions provide long Mean Time Between Assists (MTBA) and Contact life, lowering the overall cost of test.
