what is COB led strip ?   COB即Chips on Board，意思是芯片直接封装在PCB板上。COB灯带就是将芯片封装在软板上的灯带。芯片多采用倒装芯片，呈线性固晶在PCB板上，然后在芯片表面直接滴一层混合有荧光粉的封装胶水。外观酷似一条拉面粘在PCB板上，芯片发出的光在封装胶体里面通过折射、反射，以及与荧光粉的相互作用，胶体均匀的发出不同颜色，色温的光。 COB stands for Chips on Board, which means that the chip is directly packaged on the PCB. The COB light strip is a light strip that encapsulates the chip on a flexible board. Chips mostly use flip-chips, which are linearly solid-bonded on the PCB, and then a layer of packaging glue mixed with phosphor is directly dropped on the surface of the chip. The appearance is exactly like a piece of ramen [...]
