With the semiconductor memory market expected to grow significantly in the future, chip makers require a fast, high-volume test solution to keep pace with their customers’ growing demand. The dual-chamber B6700D fulfills this need by testing as many as 48 burn-in boards in parallel at speeds up to 10 MHz, which helps memory producers get their newest products to market faster while also reducing testing costs.
The burn-in tester uses a high-capacity power supply that delivers a maximum of 256 amps per burn-in board – twice that of the first-generation B6700 tester, as well as twice the driver pin resources as its predecessor, enabling it to reach higher testing frequencies.
In another advance over its predecessor, the B6700D can maintain or increase parallelism to keep throughput high as the number of stacked NAND die per package increases in the future. Additionally, the B6700D’s oven can replicate operating conditions while controlling temperature to within one tenth of a degree.
The B6700D runs on the same operating system as the earlier B6700, making the testers fully compatible. The bad block memory (BBM), universal buffer memory (UBM) and data pattern memory (DPM) functions are supported to enable NAND device testing.
