COB Means What?

What is COB?

COB is short for Chip On Board, which means that the chip is directly packaged on the PCB.
The COB light strip is a light strip that encapsulates the chip on a flexible board. Chips mostly use flip-chips, which are linearly solid-bonded on the PCB, and then a layer of packaging glue mixed with phosphor is directly dropped on the surface of the chip. The light emitted by the chip is refracted, reflected, and interacted with the phosphor inside the encapsulating gel. The gel uniformly emits light of different colors and color temperatures.

it is a new type of process technology, based on the SMD led strips with further evolution. In order to facilitate your understanding, I drew a side sectional view.

What is SMD?

SMD is the abbreviation of Surface Mounted Devices, which means: Surface Mounted Devices, which is one of the SMT (Surface Mount Technology) components. Surface mount devices have become the current mainstream electronic assembly technology due to their small size, light weight and high power.

Surface mount device packaging is to attach electronic components directly to the substrate, that is, to package and place the chip components on the printed circuit board, and use a reflow furnace to melt the solder alloy interconnected by the electronic system, thereby realizing the interconnection between the chip components and the substrate.

SMD's features

High assembly density, small size and light weight of electronic products. The volume and weight of SMD components are only about 1/10 of those of traditional plug-in components. Generally, after SMT is used, the volume of electronic products is reduced by 40%~60%, and the weight is reduced by 60%~ 80%.

High reliability and strong anti-vibration ability. Solder joint defect rate is low.

Good high frequency characteristics. Electromagnetic and radio frequency interference is reduced.

Easy to automate and improve production efficiency. Reduce costs by 30% to 50%. Save material, energy, equipment, manpower, time, etc.

what is led strips?

LED is short for Light Emitting Diode. The light strip refers to the special processing technology of the LED light welded on the copper wire or the strip flexible circuit board, and then connected to the power supply to emit light.

We can see that the chip is directly connected to the PCB board. The chip on SMD is connected to the PCB board through the bracket and the solder point. SMD’s frame of the bracket has a certain thickness, while the COB light strip does not have this bracket.
so on the same length PCB board, COB type light strips There are more chips that can be arranged, and the density is higher. One meter can reach 1000 or even 2000 pieces of chips. The brightness and uniformity of those COB led strips far exceed the SMD led strips.

COB LED Strips--Best LED Light Strips 2022

COB light strips vs SMD Light Strips

Let's light it up and see the comparison. The COB led strips have a linear light-emitting surface due to their high chip density, while the SMD led strips can see obvious light spots and dark areas. Of course, this dark area and light spot can be solved by adding aluminum profiles and diffusers, just like this. And COB light strips can become very uniform without adding diffuser. In this way, a lot of material costs and labor costs can be saved.

easy cut shorter

Parallel circuit boards, cut as long as you want, which greatly facilitates DIY and small scattered projects, COB light strips are generally packaged in a roll of 5 meters. In actual use, the length of the light strips we need will not be an integer of 5 meters. At this time, the cutting characteristics of COB led strips are very useful. Measurement The required length first. Then find the place where the COB led strips is closest to the required length, cut it along this cutting line and it can be used alone, which greatly facilitates the DIY project.

There are two ways to connect, one is to connect the solder point of the two light strips with an electric soldering iron and welding wire, and the other is to use Yiford solder-free connector.
This crystal connector has a built-in metal pin. Just press the metal pin to the solder On the solder point, the two light strips can be energized and connected. After the connection is made, there is almost no gap in the middle. At the same time, because the crystal connector is transparent, it is almost impossible to see the connector in the middle after lighting up.

Feature 15: Low heat

Feature 16: Wide emit angle 180 degree

180 degree light emitte

Wide range of lighting

Earlier we saw the structure of the COB led strips. Its chip is directly connected to the PCB. The chip emits light directly from the bottom without any obstructions, so the light-emitting angle can reach 180 degrees. The SMD led strips have a bracket, and its light-emitting angle can only reach 120 degrees under the influence of this bracket. The COB led strip with a light-emitting angle of 180 degrees can illuminate a wider range.

low heat

easy spread the heat

The copper plate has its own heat dissipation function, which can quickly dissipate the heat, and the self-heating is low. Ordinary incandescent lamps or fluorescent lamps emit a lot of heat, so you can't touch them after a few seconds of work. Since the COB chip is directly bonded to the PCB board, the heat of the chip can be quickly transferred to the PCB board. Therefore, the heat dissipation speed of the chip of the COB light strip is faster than that of the lamp bead type, and the light decay of the COB light strip is smaller and the life is longer.
