Elmo’s servo technology increases throughput for wafer testing machines.

A wafer prober is a system used for electrical testing of wafers in the semiconductor development and manufacturing process. Semiconductor manufacturers use wafer probing as a first characterization of the parts on the wafer. To enable fast, smooth and accurate operation of the testing machines, Elmo provides a complete motion control solution for the products manufacturers.

Providing total compliance with global industry standards, Elmo’s servo drives are unparalleled in performance, capabilities, and flexibility. They harness the full power of cutting-edge EtherCAT and CANopen networking communication. Advanced servo control features enable minimized settling time of the machines, while increasing the machines’ throughput, all making Elmo’s products a perfect fit for the wafer probing manufacturers.

Minimized Settling Time

Gain scheduling by profile enables the system to rapidly and automatically adjust parameters to support high-speed positioning with minimum settling time.

Compact but Powerful

The small size of Elmo’s servo drives enable the use of a smaller cabinet, minimizing machine footprint.

Boosted Performance

Elmo’s servo drives are available with a choice of EtherCAT or CANopen. The ultrafast cycle times and minimal jitter of these protocols support best-in-class real-time performance.

Fan-Less Technology

99% Efficiency generates minimal heat thus reducing the need for cooling fans and heat sinks.

Accuracy and Fast Movement

Accelerated machine throughput resulting in more output in less time.

High Reliability

Elmo’s servo drives come with a built-in drive safety functionalities such as safe torque off, a minimal failure rate and high MTBF (Mean time between failures).

Recommended Products

While all of Elmo’s Gold drives can handle the rigors of wafer probing applications, the Gold Whistle is the most popular choice for this industry for its power and footprint.
