SMD LED Vs DIP LED Vs COB LED, Which Is Better?

Today we will compare three different products, SMD LED, DIP LED and COB LED. Hope this articles can help you have a better understanding of these three products.

DIP LED

DIP LED

DIP is the abbreviation of dual inline-pin package, which is a plug-in lamp package. The display manufacturer inserts the LED lamp beads into the LED PCB lamp board, and produces DIP semi-outdoor modules and outdoor waterproof modules through wave soldering.

Due to the influence of the LED lamp bead diameter, the current minimum DIP outdoor dot pitch can only be P6, which cannot meet the market demand for higher-density outdoor display screens. However, DIP packaging is more protective, and as the first technology developed among the three packaging modes, the current production technology is very mature, and it is more suitable for outdoor large-spacing displays.

COB LED

SMD LED

SMD is the abbreviation of Surface Mounted Devices, which means surface mount device, which is one of SMT (Surface Mount Technology) components.

The viewing angle of the full-color LED display with SMD technology is larger than that of DIP, and the surface can be treated with diffuse reflection, the result is not granular, and the color uniformity is good. At present, SMD has become the default first choice for indoor and outdoor LED displays, but it also has limitations such as difficult to achieve high brightness, outdoor waterproof and poor oxidation resistance.

 

COB LED

COB is the abbreviation of Chip On Board, which means chip-on-board packaging technology. That is, a semiconductor packaging process in which the chip is glued on the interconnect substrate with conductive or non-conductive glue, and then electrically connected by wire bonding.

As a new type of packaging method, COB has obvious advantages. It can achieve P0.9 or even smaller dot pitch, which meets the market's demand for more high-definition displays. The LED display of this packaging technology is also lighter and thinner, and the surface flatness is higher. However, the current cost of COB production is relatively high, and it cannot be applied to outdoor LED display products.

The development of these three technologies, DIP, SMD, and COB, has evolved with the development of technology and market demand. They are an upgrade process rather than a complete replacement process. Therefore, there is no absolute difference between the better and the worse for these three packaging methods. The best option is to choose an LED display with a suitable packaging method according to the needs of the specific project.
