What Wentworth Laboratories does

Wentworth Laboratories is a privately held UK-headquartered manufacturer of performance wafer probe stations and cantilever probe cards serving the global semiconductor test industry. Founded in 1967 and based in Sandy, Bedfordshire, the company operates a complementary two-product portfolio: the Pegasus™ series of analytical and production wafer probers (manual, semi-automatic, fully automatic, and double-sided variants supporting wafers up to 300mm) and a cantilever probe card line spanning epoxy and blade technologies for memory, RF, logic, high-voltage/high-current, cryogenic, and parametric testing applications. Wentworth is the original inventor and patent holder of blade-type probe cards and maintains proprietary in-house design software and control firmware (LabMaster/LabMaster FA), supported by UK and US manufacturing facilities in Sandy and Brookfield, Connecticut. The company is ISO 9001 certified and holds patents across its core probe card technologies.

Wentworth serves three primary customer segments: semiconductor manufacturers conducting device characterization and production wafer test; specialized device makers testing MEMS, power semiconductors (MOSFETs/IGBTs), LEDs, optical devices, and compound semiconductors; and R&D laboratories performing failure analysis and parametric testing. The business model is hardware sales of capital equipment (probstations), consumables (probe cards with quick turnaround manufacturing), and complementary accessories such as micropositioners, chucks, environmental enclosures, and the COMPass probe card manufacturing test station. Service and applications engineering revenue is generated through the global representative network.

Go-to-market is executed through exclusive regional representatives covering more than 15 countries across the Americas, EMEA, and Asia Pacific — a network materially expanded through ten partnership agreements signed between 2019 and 2020. Pricing is not publicly disclosed and is handled through direct sales and representative channels. The company has no disclosed external funding, no parent entity, and is believed to be founder/management-owned, with growth funded organically and accompanied by headcount doubling in the 2018-2020 period.

Core offering

Wentworth Laboratories manufactures performance wafer probe stations and advanced cantilever probe cards used for semiconductor wafer-level testing. Their two main product lines include analytical and production wafer probers (manual, semi-automatic, fully automatic, and double-sided platforms for wafers up to 300mm) and cantilever probe cards (epoxy and blade variants for memory, RF, logic, high voltage, and extreme temperature applications), supported by accessories such as micropositioners, chucks, enclosures, and the LabMaster prober control software.

Product overview

Wentworth Laboratories manufactures two major product lines: wafer probe stations/accessories and cantilever probe cards/cantilever probe card manufacturing equipment. The wafer prober portfolio spans manual and semi-automatic analytical probers (FA Series, Aspect L1) for failure analysis and device characterization; semi-automatic and fully automatic production probers (Pegasus™ S200, S300, A200 series) for wafer sizes 2" to 300mm; and double-sided probers (S200D, A200D) for power semiconductor testing. Custom and bespoke prober solutions are available for specialized applications. The cantilever probe card portfolio includes standard and custom epoxy probe cards, blade probe cards, and specialized variants for low leakage, high voltage/high current, and extreme temperature (cryogenic to +300°C) environments, all manufactured in UK and US facilities. These are supported by a comprehensive accessories ecosystem including the COMPass Test Station for in-house probe card manufacturing, Pegasus™ micropositioners (PVX 400, PVX 500, Pegasus Probe), LabMaster™ FA prober control software with Python scripting, environmental enclosures (ShieldMaster™, GuardMaster™), dark boxes, anti-vibration tables, wafer chucks, microscopes, lasers, die inkers, and front ends/needle holders. The two product lines are complementary — Wentworth probers and probe cards are designed to work together as an integrated wafer test solution, though both product lines are also sold separately for use with third-party equipment.

Direct peers

• FormFactor: FormFactor is the largest pure-play probe card and wafer probe station supplier globally, offering both cantilever and advanced MEMS/vertical probe cards. Wentworth's product lines (Pegasus probe stations and cantilever probe cards) directly overlap with FormFactor's portfolio across manual and semi-automatic prober categories and cantilever-style cards.
• Tokyo Seimitsu (Accretech): Accretech/Tokyo Seimitsu manufactures wafer probing equipment and prober systems for the semiconductor industry. Wentworth's Pegasus series competes directly with Accretech's manual and semi-automatic wafer prober offerings across production and analytical test.
• Technoprobe: Technoprobe is one of the world's largest independent probe card manufacturers, specializing in MEMS and cantilever probe cards for semiconductor wafer test. Wentworth competes directly with Technoprobe in the cantilever and customized probe card segments serving logic, memory, and specialty devices.
• Micronics Japan Co. (MJC): MJC manufactures probe cards and wafer probers for semiconductor testing, with strong presence in Asia. Wentworth's cantilever probe cards and probe stations overlap directly with MJC's offerings, particularly for memory and logic test applications.
• Chunghwa Precision Test Tech (CHPT): CHPT is a Taiwan-based probe card and test interface manufacturer serving leading-edge semiconductor customers. The company competes with Wentworth in probe card categories and serves many of the same Asia-based fabs that Wentworth targets via its regional representatives.

Broad incumbents

• Advantest: Advantest is the leading semiconductor automatic test equipment (ATE) supplier and integrates with wafer probers including Wentworth's Pegasus via documented application notes. While Advantest does not directly sell probe cards, its tester ecosystem defines customer expectations for prober integration and competition.
• Cohu: Cohu is a broad semiconductor test equipment and handler incumbent that, through its historical probe card business (including the legacy Cascade Microtech and wafer-level test product lines), competes with Wentworth across probe stations and probe cards as part of a much wider test portfolio.
• Onto Innovation: Onto Innovation provides macro defect inspection, metrology, and process control equipment for semiconductor manufacturing. Its analytical and inspection tools serve similar failure analysis and characterization end-uses as Wentworth's analytical wafer probers, although via optical rather than electrical-contact methods.
• KLA Corporation: KLA is the dominant supplier of semiconductor metrology, inspection, and process control equipment. While not a direct probe card competitor, KLA's portfolio of wafer inspection and metrology systems overlaps with the broader wafer-level measurement and characterization use cases that Wentworth's analytical probers support.

Emerging players

• MPI Corporation: MPI Corporation is a Taiwan-based manufacturer of probe stations, probe cards, and test equipment with growing presence in the wafer-level test market. MPI competes with Wentworth in manual and semi-automatic probers and is a credible challenger in the same specialty and RF test segments.
