Wentworth Laboratories is the expert in wafer probing, renowned for high performance wafer probers and cantilever probe cards. Our ability to create customized and integrated wafer test solutions is second to none. Meticulous project communication and post-project monitoring ensure that our products fulfil even the most challenging requirements.
Our wafer prober products have been selected for many leading-edge wafer test applications across the semiconductor industry, leading to products such as hand-held devices, video game stations, PCs and medical diagnostic equipment. As an award-winning wafer test industry innovator, we are highly skilled in delivering wafer probers and cantilever probe card solutions. Our expertise in wafer probing, enable our customers to maximize their productivity and reduce cost.
Founded in 1967, Wentworth Laboratories has global offices and representation, and manufactures two major product lines: wafer probe stations/accessories and cantilever probe cards/cantilever probe card manufacturing equipment. In our UK facilities we manufacture wafer probers and cantilever probe cards. In the US we manufacture cantilever probe cards.
WAFER PROBERS
Wentworth Laboratories offers a wide range of production and analytical wafer probe stations to address the specific needs of various market segments and applications such as device characterization, failure analysis, design verification, thermal characterization and parametric testing. High accuracy, stability and repeatability make our probe stations ideal for MEMS, high power, RF and mmWave device testing.
We offer a full choice of accessories including manipulators, enclosures, software, chucks and microscopes. This is why our wafer probe stations can be upgraded to grow with your future requirements.

APPLICATIONS
Wentworth’s dedicated probe card teams are highly experienced in designing and building cantilever probe cards for many applications including high current, high voltage, low leakage, high temperature, cryogenic, radio frequency, multiple die and bar testing.
We have experience of building probe cards used to test displays, LEDs, MEMS, flip chip, ceramic substrates, power semiconductors including MOSFETs and IGBTs as well as optical, memory, logic and many other devices. As an ISO 9001 certified company, our professionals work closely with you to support your project from concept right through to completion.
PROBE CARD DESIGN
Central to our probe card design processes is our in-house developed cantilever probe card design software. It ensures all quality requirements including ISO9001 are met consistently by
Supporting the automated design of key components
Importing device specific data automatically to create all manufacturing documentation
Facilitating the automatic programming of key manufacturing equipment and tracking progress through the manufacturing process
Controlling state-of-the-art micro machining tools
Probe card manufacturing equipment
YOUR OWN DESIGNS
Thanks to our own custom-built software and the use of other industry standard software applications such as AutoCAD, Cadence and SolidWorks, we can accept your designs in a wide range of file types including .stl, .sld, .stp, .igs, .dwg, .dxf and .grb.
If you are looking to build or maintain your own probe cards, we also offer probe card manufacturing equipment, printed circuit boards and an extensive range of metal and ceramic needle holder assemblies.
