Our Products

We currently sell the following products:

Semiconductor Automated Test Equipment (“ATE”) is used both for wafer-level and device package testing. Our semiconductor ATE solutions consist primarily of two platforms for the system on a chip (“SoC”) device market. The Diamondx tester offers high-density instrumentation for testing various semiconductors: microcontrollers, application specific standard products (“ASSP”), power management, radio frequency (RF), display drivers, sensors and other mixed signal devices. The PAx tester is a focused tester for RF Front End IC and Module applications.

Semiconductor Handlers are used in conjunction with semiconductor ATE to automate the testing of packaged semiconductor devices. Our handlers support a variety of package sizes and device types, including those used in automotive, mobile, industrial and computing applications, among others. We offer a broad range of test handlers, including pick-and-place, turret, gravity, strip, film frame, laser marker, micro-electromechanical system (MEMS) and thermal sub-systems. T-Core is our proprietary thermal technology for improving device under test temperature accuracy, enabling higher test yield, particularly for power dissipative devices such as microprocessors, graphic processor units, and high-performance semiconductors used in artificial intelligence data centers.

Interface Products are comprised of test contactors, probe heads and probe pins. Test contactors serve as the interface between the test handler and the semiconductor device under test (such as digital semiconductor devices utilizing spring probe technology, power management and LED semiconductor devices utilizing cantilever technology) and RF semiconductor devices based on contacts designed to operate at high frequencies. With the acquisition of EQT, we expanded our interface products in mid- to high-power contactors. Test contactors and probe heads are specific to individual semiconductor device designs, need to be replaced frequently, and increase in size with the number of devices tested in parallel. Interface Products are included in our recurring revenues.

Inspection Metrology are products that provide advanced vision capabilities. We offer a wide
