What is a cob light strip?
The led engineering light strip light source is a high-efficiency integrated surface light source technology that directly attaches LED chips to a mirror metal substrate with high reflectivity. This technology eliminates the concept of brackets, no electroplating, no reflow soldering, and no SMD process, so the process is reduced. Nearly one-third of the cost is also saved a lot. The COB light source can be simply understood as a high-power integrated surface light source, and the light-emitting area and overall size of the light source can be designed according to the product shape and structure.
Cob light strips are a more common category of lighting products, but many people are confused about what is cpb light strips? rather vague.
cob: is the abbreviation of Chip on Board in English, which means the chip on board packaging technology, which can be simply understood as: a luminous body with multiple LED chips integrated and packaged on the same substrate.
Cob ready-to-package is a relatively mature LED packaging method, which is used in the field of LED lighting, and cob light strips have gradually become the mainstream products of LED light strips.
The cob light strip is a light strip that encapsulates the chip on a flexible board, and then directly drops a layer of packaging glue mixed with phosphors on the surface of the chip. The cob light strip is formed.
As a new type of linear lighting strip with high brightness and high CRI, the cob light strip has a beautiful appearance, soft and uniform light, no light spots, and has a variety of waterproof methods. It adopts flip-chip packaging technology, with good heat dissipation. Longer life.
There are two main forms of bare chip technology: one is COB technology, the other is flip chip technology (Flip Chip). Chip-on-Board (COB), the semiconductor chip is handed over and mounted on the printed circuit board, the electrical connection between the chip and the substrate is achieved by wire stitching, and covered with resin to ensure reliability.
The COB chip-on-board (COB) process first covers the placement point of the silicon wafer with thermally conductive epoxy resin (generally silver-doped epoxy resin) on the surface of the substrate, and then directly places the silicon wafer on the surface of the substrate, heat treatment Until the silicon wafer is firmly fixed on the substrate, then wire bonding is used to directly establish an electrical connection between the silicon wafer and the substrate.
