As the trend towards smaller, lighter and thinner luminaires continues to gain momentum, LED manufacturers—including Lumileds—have responded by shrinking the size of their LED packaging. One result of this trend is the growing popularity of Chip Scale Package (CSP) technology. CSP LED technology eliminates the traditional submount to directly attach the LED die to the PCB, allowing for overall system cost reductions. As fully functional LED packages that are equal to or slightly larger than the size of a die, CSP LEDs are increasingly being implemented in lighting designs.
