Built to your device, not to a catalogue.

Test Sockets

Our sockets are designed around your application from the outset. We support any package type — SSOT6, SSOT23, TO263, PQFN, WLCSP, BGA, KGD and beyond — at any lead count and size, for any handler type, down to a minimum pitch of 0.2 mm.

Where a standard part cannot meet the mechanical or thermal requirement, we design one that can.

Assembly views

Manual Test Socket with PCB

We provide the complete hardware solution including lid assembly, socket assembly with pins, PCB design/fabrication, and mounting base.

Test Socket with Lid

We provide lid assembly and test socket with different types of contacts (Pogo Pins, Contact Fingers, Offset Probes, C-Pins, etc.).

Auto-Test Socket Assembly

We provide complete test socket assembly with pins and PCB design/fabrication.

Offset Probes

Offset probes engineered for fine-pitch Kelvin measurement, with semi-circular hole anti-rotation machining capability that keeps contact geometry stable across the life of the socket.

The offset tip geometry brings force and sense contacts onto the same lead without crowding the pitch, and is available with Diamond-Like Carbon (DLC) coating for extended wear resistance in high-cycle production test.

Suitable for both low-current and high-current applications.

Pogo Pins

Single- and double-ended spring probes in hardened BeCu, palladium alloy, and gold-plated brass, rated beyond 500,000 insertions.

Supplied as complete probes or as barrels, plungers, and springs for rebuildable assemblies — with tip styles selected against your lead finish, contact force budget, and cleaning interval.

Suitable for both low-current and high-current applications.

Contact Fingers

High-quality contact fingers, fully customised, supporting a wide range of socket and handler platforms. Each series solves a different contact problem — the right choice depends on pitch, package geometry, and how much compliance the device needs.

Series characteristics

M Series

A compliant multi-bend profile. The longer sprung beam delivers a softer, more forgiving contact force and a longer wipe, which suits packages with lead-coplanarity variation and applications where mark-free contact on a soft or plated lead matters.

I Series

A short, stiff, in-line profile with a pointed contact tip. The minimal beam length gives the shortest electrical path and the smallest footprint of the three, making it the choice for fine-pitch and high-frequency devices where signal integrity and pitch density lead the requirement.

F Series

A broad flat-beam profile with a wide contact land. The larger cross-section spreads contact force and dissipates heat across a bigger area, which suits larger packages, elevated-temperature operation, and sustained high-power test conditions.

All three series are built for high-voltage and high-current applications. Selection between them is driven by pitch, package geometry, and how much mechanical compliance the device needs — not by current capacity. Exact dimensions, force curves, and ratings are issued per part number on request.

Kelvin Cantilever — Inner & Outer

A dual-path cantilever geometry that brings force and sense contacts onto the same lead at separate points, in both inner and outer configurations.

Separating the measurement path from the current path allows accurate four-wire resistance measurement on low-milliohm devices, where lead and contact resistance would otherwise dominate the reading. Available with defined pin position and socket top or side configurations.

Built for high-voltage and high-current applications.

C-Pin Series

Inner and outer C-Pin contacts engineered for high-current and high-voltage test conditions.

The C-Pin geometry maintains a controlled contact footprint on the device while carrying loads that exceed the capability of conventional spring probes — suited to power devices, automotive parts, and high-power discrete testing.

Rubber Pin

Test contact rubber pins for high-current and high-voltage applications.

Rubber pins offer low-inductance, low-profile connection for fine-pitch and high-frequency devices where mechanical spring contacts are impractical — with the compliance to absorb coplanarity variation across a large contact array.

Socket Body / Housing

Socket bodies and housings supplied without pins, fully customised to your mechanical envelope.

Ideal for customers with an established contact standard who need the housing, alignment, and retention engineered to their own specification.

Test PCBs — DUT Cards & Load Boards

Quick design turnaround with short fabrication lead times: 20-layer boards in two weeks, hard gold plating, and 0.4 mm pitch pad technology for restrictive mechanical requirements.

Burn-in Application

Burn-in boards, sockets, and fixtures for accelerated life testing — built to survive the oven, not just the bench.

Burn-in subjects devices to elevated temperature and voltage over extended periods, forcing infant-mortality failures out before parts ever reach your customer. That makes the hardware itself the constraint: boards and sockets sit above 125 °C for hours at a time, cycle after cycle, and any drift in contact resistance or board flatness surfaces as false failures in your yield data.

We supply burn-in boards built on high-temperature substrates such as polyimide, together with the burn-in sockets, contacts, and mechanical hardware that populate them — specified against your device, your board layout, and the thermal and electrical conditions of your oven.

Coupon Board

We specialize in custom design and fabrication, strictly tailored to the customers material specifications—including High-TG FR4, Rogers, Ventec, Arlon, and other advanced and high quality laminates.

Change Kits, Stiffeners & Handler Parts

Conversion kits and stiffeners for all major handlers, together with handler parts and service.

A wide range of handler platforms is supported, with new platforms added on request.

Spare Parts, Fixtures, Alignment Plates & Socket Lids

Alignment plates, retainers, socket lids, test fixtures, and mechanical spares.

Manufactured to the same tolerances as the primary hardware, so that a replacement part performs like the original rather than becoming a new variable in your test data.

Precision Mechanical Components

Custom mechanical parts, CNC-machined components, precision plates and fixtures, engineering prototypes, and custom tooling.

Manufactured to drawing and verified dimensionally before dispatch.
