Blade Probe Cards: Low Leakage / High Frequency / High Temperature

Founded by the inventor of the fixed-point blade-type probe card, Wentworth offers a wide variety of finished blade probe cards for low current, high temperature and radio frequency applications. Wentworth also supplies individual standard and specialty blades, printed circuit boards and a build / maintenance system that enables you to build your own metal and ceramic blade probe cards.


Wentworth blade products include standard metal or ceramic blades; metal mini-blades; metal micro-blades; special IC metal blades; metal hybrid circuit blades; and stripline high frequency ceramic blades. Most blade shapes are available in several sizes, and all can be combined with a selection of needle probes to provide custom needle holder assemblies. Additionally, three types of edge sensor probes are available: standard; 2-wire isolated; and 3-wire isolated.


Wentworth supplies a complete turnkey package for test floor managers who wish to establish on-site capability to build and maintain blade probe cards.

Probe Card Design Service


Engineered Solutions

Wentworth's probe card design service utilizes sophisticated software, practices and communications tools to bring your designs to life. We offer a full complement of generic and automated test equipment (ATE)-specific design services. Our expertise ranges from the development of low pin count, high frequency ceramic blade cards for GaAs devices, to custom high current / high voltage cantilever probe cards that can support in excess of 200 amps.


Wentworth has developed an extensive library of master templates for all major tester platforms utilizing advanced design software for quick-turn printed circuit boards. Sophisticated mechanical design modelling software speeds the custom design of complex epoxy cantilever probe cards.


Wentworth PCB designers are skilled in actualizing the most sophisticated designs. Our robust radio frequency and signal integrity PCB design capabilities include: impedances control, trace length matching, differential pair routing, bypassing, and optimized power and ground planes.


For custom generic PCB design, sunburst patterns can be created for optimum power supply access and filtering, and internal routing may be optimized for peak frequency response, impedance matching and line lengths between pogo towers.
