Chromium Chip On Board (COB) Fine Pixel Pitch LED Video Indoor Boards
Chip-On-Board (COB) Technology
Chip-On-Board (COB) Technology solders three (3) LED chips, 1 red, 1 blue, 1 green, directly onto a PCB board. The SMD process inserts the three (3) chips into a bulb/lamp which lamps are then affixed to a PCB Board. The Chip-On-Board (COB) Technology manufacturing process results in a perfectly flat, uniform LED surface allowing for a flawless encapsulation of the chips using a clear epoxy resin. The encapsulation of SMD bulbs cannot result in a perfectly flat surface.
Chip-On-Board (COB) Technology is a two (2) step manufacturing process as opposed to the four (4) step SMD process. THE COB manufacturing process eliminates the need for a bracket and supports, thereby reducing the number soldering steps and as a result the number of possible failure points. See the diagram below. Chip-On-Board (COB) Technology is up to ten (10) times more reliable than SMD. 10/ppm vs. 50- 100/ppm.
The encapsulation of the LED chips using clear epoxy resin creates a protective surface that is highly impact resistant. Chip-On-Board (COB) Technology is a safeguard against the intrusion of humidity, and is also anti-static, anti-dust, and waterproof on the front of the display. Chip-On-Board (COB) Technology also provides for a higher contrast ratio, sharpness and deeper colors than SMD/GOB.
Chip-On-Board (COB) Technology will allow for exceptionally low, very reliable pixel pitches. The present reality is that SMD technology below P1 is unstable. To date SMD 0808 and Mini 4-in-1 technology is not dependable. Chip-On-Board (COB) Technology has perfected the P0.94 and is developing P0.5! Incredible!
