Semiconductor test sockets.
Precision at every contact.

THE MXPAC APPROACH

Test Socket & Fixtures

MXPAC provides semiconductor test socket and fixture engineering in Penang, Malaysia. We engineer the interface between device and tester—balancing contact, alignment, access, serviceability and production handling.

DESIGNED OUTCOMEA robust, serviceable test interface designed for consistent contact and production use.

TEST SOCKET SOLUTIONS

The contact technology
behind a reliable test.

Match the socket to the device package, electrical test and operating conditions. Our scope brings together contact selection, custom socket design, fabrication and integration with the mechanical and thermal test setup.

Range of semiconductor test socket assemblies and device packages from the supplied socket overview
Socket and contact configurations for different device packages and test arrangements.
01 / SELECTContact technology

Rubber, spring-probe, rigid-pin, cantilever and coaxial approaches.

02 / CUSTOMIZEPackage interface

Socket geometry, alignment, contact arrangement and fixture requirements.

03 / INTEGRATEComplete test setup

Load-board interfaces, mechanical support and thermal-system compatibility.

TECHNOLOGY OPTIONS

Choose around the test requirement.

Each contact family addresses a different combination of contact force, compliance, current and signal performance.

01 / RUBBER & ELASTOMER

Compliant contact
for sensitive devices.

Soft silicone-rubber contactors support semiconductor testing where ball or pad damage and contact force are important considerations. The supplied material includes BGA/LGA and memory applications, with fine-pitch and high-speed options.

Review for your application
Pitch, contact force, stroke, contact resistance and operating temperature.
Spring probe contact pin examples with different tips and spring geometries
02 / SPRING PROBE

Contact compliance
across device interfaces.

Spring probes offer travel to accommodate package non-coplanarity. Options in the presentation include fine-pitch, Kelvin, RF, high-current and non-magnetic pins, with the contact geometry selected for the test environment.

Review for your application
Tip shape, travel, force, current, package flatness and maintenance access.
Cantilever contact mechanism shown in rest and compressed conditions in the supplied socket summary
03 / SHORT RIGID PIN & CANTILEVER

Contact structures for
demanding electrical tests.

The supplied presentation positions short rigid-pin sockets for 5G and other high-frequency applications, and cantilever sockets for automotive and high-power testing. Select the structure around the electrical path and loading requirements.

Review for your application
Signal path, current, contact arrangement, alignment and mechanical loading.
Coaxial test socket contact array from the supplied JF Technology presentation
04 / COAXIAL

Shielded signal paths
for high-frequency testing.

Coaxial socket structures use a metal housing and controlled contact geometry to address impedance and crosstalk. The presentation includes BGA and WLCSP examples, plus independent coaxial channels and differential-pair arrangements.

Review for your application
Pitch, test height, impedance, insertion loss, return loss and pin assignment.

Technology descriptions and selected images draw on the supplied JF Technology presentation. Product-family capabilities vary; the final socket configuration and performance are confirmed against your device and test requirements.

FROM SOCKET TO TEST STATION

Make the interfaces
work together.

A socket is one part of the test system. Define the board connection, device positioning, contact loading and thermal access together.

01

Test interface products

Review the load board, adaptor and fixture arrangement around the DUT and tester, including access for assembly and service.

02

Mechanical integration

Coordinate device guidance, clamping and support with the contact stroke and force needed for repeatable engagement.

03

Thermal integration

Plan thermal-head access and the socket’s operating range together for temperature-conditioned testing.
