Advantest announced the M6242 dynamic test handler in May 2008 for high-volume DRAM production, with a vendor-rated throughput of 42,200 devices per hour—more than twice the M6241 predecessor’s throughput. The M6242 supported BGA, CSP and TSOP1 packages and could test up to 512 devices simultaneously. Those are manufacturer specifications, not independently measured production-line results.
What is the Advantest M6242?
The M6242 is a semiconductor test handler: equipment that moves packaged devices through a tester, maintains the required thermal conditions and sorts devices after testing. Advantest positioned this model for mass-production DRAM lines. Its supported package types included BGA, CSP and TSOP1.
Advantest’s product page called it the “Optimal Test Handler for Mass-Production DRAM, with Double the Throughput.” Advantest M6242 product page
How much faster was the M6242 than the M6241?
Advantest rated the M6242 at 42,200 devices per hour and described that as more than double the M6241’s throughput. EE Times also reported the more-than-twofold comparison in 2008. Neither figure should be treated as a guaranteed rate for every device, tester setup or production line. EE Times coverage of the 2008 announcement

What does dynamic test-handler throughput mean?
Throughput is the number of devices a handler can process in a given time. In this case, 42,200 devices per hour is Advantest’s stated maximum for the M6242, rather than a report of independently verified factory output. Real production results depend on the device and line configuration, among other operating conditions.
Parallel test capacity is a related but distinct measure. The M6242 could handle up to 512 devices in simultaneous testing, according to Advantest. That capacity does not by itself determine hourly output: transfer time, test duration and device handling also affect throughput.

How did Advantest say the M6242 achieved the increase?
Advantest attributed the throughput gain to more efficient device transfer, using optimized arm mechanisms to sort devices into good and bad results after testing. The company also cited improved temperature stabilization. It specified ±1.5°C accuracy when the temperature was set from -10°C to 100°C and described this as a 25% precision improvement over the M6241. These are manufacturer claims for the product, not independent test findings. Advantest M6242 product page

Later models illustrate why throughput alone is not enough to establish that one handler can replace another. The M4841 brochure and M5241 announcement describe different device targets, package or temperature capabilities, and parallel-test configurations.

The M5241 announcement’s stated first-shipment timing is a schedule, not confirmation here that shipments began. The M4841 and M5241 figures provide product-development context; they do not establish that the M6242 is currently available for new purchases or interchangeable with either later model.
Quick Recap
What to compare when evaluating a handler
- Throughput: Check the stated rate and the configuration or conditions behind it; do not assume a vendor maximum equals sustained line output.
- Parallel capacity: Confirm the number of devices the handler can support for the exact test setup.
- Device and package compatibility: Match the handler to the memory generation, device type and package used in production.
- Thermal requirements: Compare the operating range and temperature-control performance against the test program’s needs.
- Line integration: Verify automation, sorting and maintainability requirements with the vendor for the intended production line.
