Do you know the circuit board production of LED light strip board?

It refers to assembling the LED chip on the PCB hard board, and because its shape is similar to the tape, it is called the LED hard light strip.

Assembly form: The LED hard light strip uses as the circuit board, and uses LED chip for assembly, or uses in-line assembly. There are differences between the two: the chip type is relatively stable, and it is not easy to fall off, to ensure that the LED chip can be used normally; The in-line type is simple and convenient, but the arrangement is not very neat, which is easy to fall off, leading to chip damage.

LED hard light strip process:

pcb board

Solder paste printing → patch (LED&resistance) → QC visual inspection → reflow soldering → QC low-voltage lighting test → assembly (PCB&aluminum body) → aging test → aging test → finished product inspection → QC shipment * * final inspection → packaging and shipment

LED light strip

Features of LED hard light strip:

1. High quality and high brightness LED is used as the light source, with low power consumption, no heating, bright color and long service life.

2. DC24V DC input, IC constant current drive, energy saving more than 70%.

3. High light transmission PC cover is adopted, with high color rendering index, restoring the real color of the item

4. The interior of the lamp strip is filled with high heat dissipation glue, and the power cord is waterproof, which can dissipate heat quickly

5. Wide range of applications, indoor and outdoor can use the corresponding led light bar.

6. The installation and construction are convenient, but the disadvantage is that the led hard light bar cannot be bent at will.

7. It does not contain harmful environmental substances and has a long service life,.

The strip is divided into flexible LED light strip and LED hard light strip. The differences are as follows:

1. The flexibility is to make PCB boards and use them for PCB assembly, so that the thickness of PCB products is only the thickness of a coin and does not take up space; The general specifications include 18 LEDs with a length of 30cm, 24 LEDs, 15 LEDs with a length of 50cm, 24 LEDs, 30 LEDs, etc. There are also 60cm, 80cm, etc. Different users have different specifications. It can be cut or extended at will without affecting the light emission. The FPC material is soft and can be bent, folded and wound at will. It can move and expand freely in three-dimensional space without breaking. It is suitable for irregular places and narrow spaces. It can be bent and wound at will, so it is suitable for any combination of various patterns in.

2. The LED hard light strip is an assembly circuit board made of PCB hard board. The LED can be assembled with a chip LED for PCB assembly or a in-line LED for assembly. Different components can be used as needed. The advantages of the hard light strip are that it is relatively easy to fix, process and install; The disadvantage is that it cannot be bent at will and is not suitable for irregular places. There are 18 LEDs, 24 LEDs, 30 LEDs, 36 LEDs, 40 LEDs and other specifications for chip LEDs used for hard light strips; There are 18, 24, 36 and 48 in-line LEDs in different specifications, including front and side LEDs.
