LED technology has made great leaps in 2013. As LED prices continue to fall, large LED manufacturers are focusing on packaging process and material to develop low cost technologies. “Package free technology” has no doubt become the most important technological breakthrough this year that has surprised the industry. Unistars has been using advanced wafer package technology, Chip Scale Package (CSP). The company has released its new CSP series product Mercury 1515 series, and is the first Taiwanese LED packager to mass produce CSP products.
