The PCB boards are classified as different types including single layer PCB, double layer PCB, multiple layers PCB, and rigid PCB, flexible PCB, rigid-flex PCB, and Aluminum circuit boards. In order to better understand the soft light strip, here we first analyze its material FPCB.
With the advancement of technology, LED PCB Strips are becoming more and more popular. The addition of flexible PCB further makes LED strips provide great convenience in home lighting and decoration. The following will take you to a comprehensive understanding of the structure of the flexible PCB and its role in the LED strip.
What is Flexible PCB?
Flexible printed circuit board, also known as flexible printing or flexible circuit, is a special type of PCB which you can bend to any shape you want. They are mostly used in high temperature applications,as well as high density applications. The flexible design pcb is composed of polyimide(PI) or transparent polyester film as the substrate material, which has high heat resistance and is very suitable for welding installation components.
What Does It Act On The LED Strip?
LED strips are basically circuit boards that are connected to each other. SMT (Surface Mount Technology)refer to make SMD LEDs and other components such as connectors mounted on flexible PCBs. In other words, the FPCB acts as a substrate on which the manufacturer mounts the LED chips.
Besides being its structure, another main function of a circuit board is to dissipate heat. Click to learn more about the features and applications of flexible PCBs.
Structure of a flexible PCB.
Flexible electronics are with good plasticity and perfect for LED strip lights. The 5-meter reel is the most common flexible substrate setup for LED strips.
Like rigid pcb, FPC can be classified into single-layer, double-layer or multi-layer PCB circuits.
Single layer FPCB
A single-layer circuit board consists of a base layer and a conductive layer. Solder mask oil and silkscreen protect these layers. It has no circuitry on the back.
They have a thin structure, only 1 oz thick. You feel very light when you hold them.
Double layer FPCB
Compared to a one-side PCB, a two-side PCB has two copper layers, which makes it thicker and heavier because it has a conductive layer on both sides.
They are also more durable because the board can handle higher currents and dissipate heat better.
In the current lighting market, we can find that both single-layer PCB and double-layer PCB are used for LED strips. After removing the tape on the back of the LED strip, the difference between the two PCBs can be clearly seen.
Some led strip lighting manufacturers select single layer PCB to reduce cost. Although double-layer PCBs are more expensive, LED strips made from them have higher lumens and better heat dissipation, which significantly improves their stability and longer lifespan.

What are the applications of Single & Double-layer PCBs?
1, Single PCB panels may not be as complex as other panels, but they power a variety of everyday electronics. Because of their low manufacturing cost, you can find them in mass production equipment, such as:
Lighting / Camera systems / Audio equipment / Power supplies / Calculators / Solid-state drives / Printers / Surveillance.
2, 2layers PCBs are one of the most popular PCB types because they enable manufacturers to produce more complex circuits, which is conducive to the use in higher technology applications and electronic products. Double-sided printed circuit board can be used in the application of electronic products and electronic products are very widely, such as:
Power Supply / HVAC system / Power Conversion / LED lighting / Printer / Hard disk drive / Telephone system / Vending machine / Traffic system / Car dashboard.
Two-sided PCBs can be made with a variety of custom designs, such as silver and gold finishes, high-temperature materials and solder coatings. This versatility enables them to power an almost unlimited lot of projects at a cost-effective price.
