Second step is to cover the led chip with phosphor, then cob strip can be different color. After cover with the phosphor, cob strip will put into the specific oven, then we'll test the strip again to ensure all LED Chip works well. The last step is same as normal SMD Strips, sordering the 0.5m PCB together.
