LED-COB Encapsulation Onl Filling Powder Tester

This system is used to test the LED COB in high speed and accuracy. It has intelligent PIN function.high accuracy(Use air compressor to drive and position the COB coordinate,which make the COB always in the same position and reduce the error caused by the position change of COB)High speed(It lights up all the COB in the same fixture one by one)

Applied Range

It is the ideal instrument for COB production line testing, sorting and quality control.
