记忆体测试设备 Eureka

Eureka 对记忆模组进行快速的功能动态测试，并采用多个先进的检查模式来检测出短/断路**、单一颗粒**、记忆胞间的绝缘**、时序及杂讯问题引起的间歇性**…等记忆体测试设备 Eureka
加装选购的漏电流测试转接模组后，即可进行半导体漏电流特性的测试，并能检出DRAM晶片的微小漏电流。
Eureka 具有内建的SPD(serial presence detect)烧录器可用来烧录及验证测试SPD内容，可在记忆体模组测试时随同进行。
Eureka加入了许多加强功能来提升测试的正确性，像晶片预热chip-heating，电源电压变动模拟voltage bouncing，循环(回路)测试loop test，
可调式时基adjustable timing parameters (selected)，可调整式更新模式及周期alterable refresh mode and cycle，更新测试refresh test，
ICC电流测定，也有Address与RAS/CAS测试，不论有/无缓冲级的模组，Eureka都能支援同位与ECC 位元检查，
另外，Eureka也能配合CST*新的RoboFlex自动取置机 来进行全自动测试，其效能表现更是如虎添翼，此外，可额外选购加装的测试配备有Flash testing，
Cache testing，DRAM & SDRAM TSOP Chips testing
