ROSENHEIM, Germany — esmo group (esmo), a leading global supplier of manipulators, docking and interfacing components, and handling systems for the semiconductor industry, introduces Vulcon®, a family of contactors developed for semiconductor final test. Completing esmo’s test cell portfolio in the company’s 25th year, Vulcon® contactors are sold for use on any handler brand, esmo’s own included.
The Last Element of the Test Cell
Since 2001, esmo has supplied the mechanical systems that surround the tester: the manipulator that positions the test head, the docking and interfacing system that connects it, and the handler that presents each device. That work now extends to the contactor itself.
Developed in-house, Vulcon® is one product family covering a wide range of applications, with solutions configured to the specific test and customer requirements.
“Our customers could always come to us for the handler, the manipulator, and the docking system,” said Josef Weinberger, Head of Business Unit, esmo semicon. “Contacting was the gap, and it is the part closest to the device. Closing it means we can stand behind how the whole cell performs.”
Open to Any Handler
Vulcon® works with handlers of any make, and esmo supplies the range to the final test market as a whole.
In high-volume production, the handling system and the contactor are usually supplied by different vendors, and a test floor will commonly run equipment from several manufacturers. Vulcon® can be specified across that mix, regardless of which handler holds the device.
Where a customer already runs esmo handling, docking, and interfacing systems, the contactor completes the cell. esmo then supplies every mechanical element between the tester and the device, and carries responsibility for how all of it performs.
Built for Final Test Conditions
At launch, the Vulcon® family is aimed at power device test for automotive and industrial applications, including the power supplies behind AI data centers. Alongside the hardware, esmo pairs the family with engineering support, working with each customer to match a configuration to the test requirement in front of them.
“Cost of test is what our customers are working to reduce,” Weinberger added. “Longer contact life, higher test yield, and longer intervals between cleaning all feed into that. Just as important is understanding what a test floor realistically needs and then building to it.”
Availability and First Shipments
esmo is showing Vulcon® at SEMICON Europa 2026 in Munich, from 10 to 13 November, on booth C1241. First shipments reach customers in Europe and Asia before the end of the year.
