Product Specs
70% of COB quality issue coming from wire bonding?
It is reported 70% of COB quality issue comes from broken wires which connect blue chips each other.
Based on the cutting edge Flip-chip technology, GMKJ Flip Chip COB does not require any type of wire bonding. Unlike the traditional lateral chip COB, GMKJ COB is free from any potential damage from wire bonding. Saving cost without wire bonding also provides you better cost position.
