  5 meter COB led strip IP20 24V - Warm wit 3000K!COB is the abbreviation of Chip on Board, which means chip-on-board packaging technology, a light-emitting body in which multiple COB LED chips are integrated and packaged on the same substrate.

  COB led light source is a high-efficiency integrated surface light source technology in which the LED chip is directly attached to a high-reflectivity mirror metal substrate.

  The light-emitting area and external dimensions of the light source can be designed according to the product shape and structure such as round or square.

  The led light emitted by the chip undergoes refraction, reflection, and interaction with phosphors in the encapsulating gel, and the gel uniformly emits light of different light colors and color temperatures.



  After making the COB substrate, apply a white coating. Use the SMT machine to attach the COB chip to the flexible PCB board.

  Cover the silicon wafer placement point with a thermally conductive epoxy on the surface of the substrate, then place the silicon wafer directly on the surface of the substrate, heat treatment until the silicon wafer is firmly fixed on the substrate, and then use wire welding to connect the silicon wafer and the substrate and establish an electrical connection directly between them.

  Finally, encapsulate the COB light strip. After the production is completed, cut into a strip of light and roll it into a reel.

  And this is how the COB led light we have seen was produced.

  This technology eliminates the concept of stents, so the process is reduced by nearly one-third, and the cost is also saved by one-third.
