Opinion: Chip scale packaged LEDs are far away from mass production

摘要

Chip scale packaging for LEDs was regarded as a revolution in the packaging industry two years ago. Recently, I was involved in a project related to chip scale packaging in the LED market. In the investigation I found that the mass production of chip scale packaging LEDs is not available anywhere in the world, even in China which is the biggest LED packaging market. This is because while production is technically possible the cost of single chip is much higher than the common surface mounted device/chip on board packages.
