PCB Technical - PCB board production of LED light strips

It refers to assembling the LED chip on the PCB hard board, and because its shape resembles a belt, it is called LED rigid light bar.
Assembly form: LED rigid light bar adopts PCB as circuit board, adopts LED patch for assembly, or adopts direct insertion type for assembly, there is a difference between the two: the patch type is relatively stable, not easy to fall off, to ensure that the LED chip can be normal Use; while the in-line type is simple and convenient, but the arrangement is not very neat and easy to fall off, causing damage to the chip.
LED circuit board production process of rigid light bar:
Soldering paste-SMD (LED&resistance)-QC visual inspection-Over-reflow soldering-QC low voltage lighting test-Assembly (PCB&aluminum body)-aging test--aging test-finished product inspection-QC shipping** final inspection- Pack and ship

Features of LED Rigid Strip:
1. Use high-quality and high-brightness LED as the light source, low power consumption, no heat, bright colors, and long life.
2. DC24V DC input, IC constant current drive, energy saving more than 70%.
3. The use of high light transmittance PC cover, high color rendering index, restore the true color of the article
4. The inside of the light bar is potted with high heat dissipation glue, and the power cord is waterproofed to quickly dissipate heat
5. It has a wide range of adaptability. Corresponding LED strips can be used indoors and outdoors.
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 strips are divided into two types: flexible LED strips and LED rigid strips. The differences are as follows:
1. The flexible LED light bar board is made of FPC as a road board, and used for assembly, so that the thickness of the product is only the thickness of a coin and does not take up space; the general specifications are 30cm long 18 LEDs, 24 LEDs and 50cm long 15 LEDs, 24 LEDs, 30 LEDs, etc. There are also 60cm, 80cm, etc., and different users have different specifications. And it can be cut at will, and it can be extended at will without affecting the light emission. The FPC material is soft, can be bent, folded, and wound arbitrarily, and can be moved and stretched in three-dimensional space without breaking. It is suitable for use in irregular places and places with small spaces, and because it can be bent and wound arbitrarily, it is suitable for arbitrarily combining various patterns in it.
2. The LED rigid light bar is assembled with PCB rigid board. LEDs can be assembled with SMD LEDs or in-line LEDs. Different components are used according to different needs. The advantage of the rigid light bar is that it is easier to fix, and it is more convenient to 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 many other specifications of SMD LEDs for rigid light bars; 18 LEDs, 24 LEDs, 36 LEDs, 48 LEDs are used for in-line LEDs. There are different specifications, and there are front and side ones.
