Micro LEDs whose size is calculated at the micron level and the number of micro LEDs used are calculated in millions. The road to mass production is full of thorns. The chip alone is faced with many problems such as low chip efficiency, low mass transfer efficiency and low yield, and difficulty in detection and repair. Difficulties. In order to promote the commercialization of Micro LED, related equipment manufacturers continue to make efforts to provide feasible solutions for the market. Recently, a Korean Mini/Micro LED testing equipment manufacturer announced the latest news.
According to Korean media reports, South Korean Mini/Micro LED testing equipment manufacturer NANO X announced on the 15th that it has received a total of 5.5 billion won (equivalent to RMB 29.09 million) investment from investors such as C&CI Partners. The funds are planned to be used to build a Micro LED test probe. Needle mass production line.
NANO X revealed that the large-scale production line of Micro LED test probes is expected to be completed in May, and the monthly production capacity of probe cards is expected to be 6,000 pieces. The pin card is mainly used to test the performance of Micro LED chips. When applying current, the probe card tests whether the Micro LED chip works normally by checking parameters such as voltage change, wavelength, and light intensity.
It is reported that NANO X's Micro LED test probes consist of pins with a size of 5-10μm, which directly contact the Micro LED chips and test each chip. It is worth noting that each pin has an independent spring structure, which can deal with non-contact and other problems that may occur when the height of the Micro LED chip is different.
Young-sung Park, CEO of NANO X, said that the company provides Micro LED performance evaluation services for domestic and foreign customers. After the large-scale production line is completed, the company will promote the commercialization of Micro LED probe cards. Currently, NANO X is expanding its business scope.
