Dynamic test handler takes
up to eight SoCs

Advantest's M4541AD is a dynamic test handler capable of testing up to eight SoCs or other logic devices simultaneously - twice the capacity of its predecessor

Along with its ability to connect with SoC test systems to support fast manufacturing-line testing, the M4541AD can also be used together with memory test systems. This latter capability is important because it provides a cost-effective solution to the practice of distributing the burden of lengthy SoC testing between both SoC and memory test systems to optimise efficiency ("two-path testing").

The M4541AD also employs a new device handling mechanism and optimises the motion efficiency of the handler's pickup arm, which helps cut test costs by providing shorter index times and a maximum throughput of 6000 devices per hour.

To make the most out of its customers' investments in capital equipment, Advantest has developed a new architecture for its device interfaces.

This incorporates a new "layout unit", which forms an additional layer between the handler and the company's existing device interfaces.

By simply changing this layout unit, users will be able to adjust the handler to different socket arrangements and pitches, and varying amounts of simultaneously tested devices, thus eliminating the need for customers to invest in additional handlers designed for use with specific IC packages.

The M4541AD also offers a small footprint, increased energy-efficiency, and a heating plate to enable testing of high- temperature chip performance up to 125C.

The M4541AD employs a new pressure control mechanism that allows steady, constant pressure to the device under test, helping to reduce contact failures and thus to increase handler reliability.

This improvement is especially evident when handling high-speed devices that use sockets that require short contact strokes.

Also, the new motorised pickup arm automatically adjusts its stroke and speed, helping prevent devices from cracking and chipping.
