Vanguard Chromium Series
Vanguard announces its Chromium Fine Pixel Series. Direct Chip to PCB (DCP) 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 Direct Chip to PCB (DCP) 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.
THE COB manufacturing process eliminates the need for a bracket and supports, thereby reducing the number of soldering steps and, as a result, the number of possible failure points.
Direct Chip to PCB (DCP) 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 of soldering steps and, as a result, the number of possible failure points (as illustrated in diagram). Direct Chip to PCB (DCP) 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.
The encapsulation of the LED chips using clear epoxy resin creates a protective surface that is highly impact resistant. Direct Chip to PCB (DCP) technology is a safeguard against the intrusion of humidity, and is also anti-static, anti-dust, and waterproof on the front of the display. Direct Chip to PCB (DCP) technology also provides for a higher contrast ratio, sharpness and deeper colors than SMD/GOB.

Direct Chip to PCB (DCP) 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, Vanguard reports. Direct Chip to PCB (DCP) technology has perfected the P0.94 and is developing P0.5, according to the company.
