1. LED aluminum PCB
Led aluminum PCB also is known as LED PCB aluminum. It has good conductivity and is widely used in the LED industry. It has a very good performance in thermal conductivity and reflective performance. LED aluminum-based circuit board also has good cooling and heat dissipation performance, which is beneficial to extend the service life of LED products.
2. LED Strip
LED lamp strips are generally divided into two types: LED flex lamp strips(LED flexible PCB or LED flex PCB), and LED rigid lamp strips (LED rigid PCB).
A. The flexible LED light strip adopts FPC as the printed circuit board assembly and uses the patch LED to assemble so that the product is as thick as a coin thus saving space. Its general specifications are 30cm long (18 LED, 24 LED) and 50cm long (15 LED, 24 LED, 30 LED). There are also 60cm, 80cm, etc. and different users need different specifications.
It can be cut or extended without being affected. The FPC material is soft and you can bend, fold or wind it at will. It can move and stretch freely in 3d space without breaking. Thus it is suitable for being used at irregular and narrow positions, and suitable for advertising decoration in any combination of all kinds of patterns.
B. LED rigid light strip is made of rigid PCB board. LED rigid PCB can be assembled by patch, or directly inserted with LED, depending on the needs of different components. The advantage of a rigid light strip is that it is easy to fix, convenient to process and install. There are 18 LED, 24 LED, 30 LED, 36 LED, 40 LED, and many other in-patch assembly specifications. For assembly with directly inserted LED, there are the 18, 24, 36, 48, and other different specifications. In addition to the installation of LED in the front, an LED rigid light strip can also be installed in the side (sidelight is also known as the Great Wall light strips).
3. LED display PCB board
The LED display is a flat panel display. It is composed of many small LED module panels and is used to display text, images, video, video signal, and other information devices. From the earliest P31.25 outdoor screen to the current P1.58 indoor screen, the LED display PCB board used in it is more and more sophisticated, and the LED PCB board design and production are more and more excellent. For example, the designed pad size of the P1.58 LED display PCB board, which is a second-order HDI board, is only 0.15mm.
