Blade Probes

BLADE PROBES

As the original inventor and patent holder of blade type probe cards, Wentworth Laboratories manufactures blade probes (also known as needle holder assemblies) for a variety of different applications. These are an essential part for any organisation, who wishes to build or maintain their own blade probe cards.

Each of our basic blade probe shapes come in several sizes, and can be combined with your choice of needle to provide custom blades to suit your application. We offer solutions to fit standard and custom PCBs. A wide choice of options is available to tailor the blade probe to meet your test requirements. 

Choose your Blade parameters

  • Material
  • Gram force

  • Probe plating

Available probe materials

  • Tungsten (W)
  • Tungsten rhenium (WRe)
  • Beryllium copper (BeCu)
  • Palladium alloy (Pd), also known as Paliney®
  • Gold plating 

Metal blades

Our standard metal blade probes are available in a wide variety of different shapes and sizes. Their robust and stable design makes them suitable for most applications including multi-level probing. We can also provide longer reach blades for custom geometries on boards with wide opening sizes.

ceramic blade probe

standard ceramic blades

Our ceramic blade probes are available in two different shapes. Their high rigidity and slim design make them ideal for higher density applications. Thanks to their non-conductive characteristics, they are often used to reduce leakage and noise for parametric applications. Traditionally, these types of blade probes were also used in high temperature applications.

stripline ceramic blade probe

High frequency stripline ceramic blades

We offer three different types of high frequency stripline blades to cater for different applications. With their fixed impedance at 50 ohm they are specifically designed for high frequency applications up to 4 GHz. They are also ideal for low leakage applications and can achieve values in the femto Amp range.

BUILDING YOUR OWN PROBE CARDS

Blade probe cards are ideally suited for organizations wishing to build or maintain their own probe cards in-house. 

If you are looking to build your own probe cards, we offer manufacturing equipment to assist with the building, maintenance and repair. In addition, to blades we also offer a wide range of standard and custom PCBs.
