Evertechno recently announced that they invented the world's fastest ‘memory test handler' called EV5. Evertechno specializes in manufacturing LCD and semiconductor devices. According to one of the staff from Evertechno, this EV5 device can check all 512 to 1,024 semiconductor chips in parallel and has been developed to test out 55,000 chips per hour, marking it the fastest memory test handler inland and is expected to increase productivity by a large scale.
Memory test handler's basic scope is that it verifies chips that are completed in packaging and sorts out defective products from useful ones based on their electronic characteristics. Comparing from the former memory test handlers, the newly manufactured EV5 can check out 55,000 per hour than the original 36,000 to 43,000 per hour speed. The testing cycle time of EV5 requires 37 seconds whereas the previous ones require at least 45 to 60 seconds. The most important part in the memory test handler is the 'chamber' and its reliability range is ±1.5°C compared from earlier, which was ±2°C to ±3°C. Nonetheless, first and foremost, picker's pitch is the vital part in the device for it allows the transferring of chips. The previous pitch was activated via manually, but this current EV5 transfers chip automatically, in which also carries the benefit of shorter conversion time from the original 30 minutes to the shortened 10 minutes.
The chief executor in development/vice president, Kim Hyun-ho said, “Our memory test handler is already a high-end product that is noted not only in Korea, but also around the world. Many semiconductor manufacturers are competing to develop memory test handlers that have shorter testing time to increase productivity to the max and thus for the future, our company will produce test handlers that are both the fastest and strongest." In addition, Yeom Jeong-tak, the department head, said, “today's consumers favor a device that has good performance and fast speed with no jam or breakdown.”
In relation, Evertechno has 18 applied patents, two registered patents, and one patent that is applied abroad. They recently completed the development of Solid State Drive (SSD) and are preparing to mass-produce state-of-the-art semiconductors in the forthcoming future.
