Aluminum-base Single-Sided LED PCB

Keywords：Advantages of Single Sided PCB, Applications of Single Sided PCB, Fabrication Process of Single Sided PCB

Jinghongyi PCB is a PCB supplier and manufacturer in Shenzhen, China, which can produce Aluminum-base Single-Sided LED PCB, street light PCB, tunnel lighting PCB, light round PCB, etc. Aluminum-based LED PCB, different from double-sided PCB, belongs to single-sided PCB, that is, PCB products with only one side of the circuit. However, the advantages of the aluminum substrate are particularly obvious. It has good thermal conductivity, electrical insulation, and machining performance. Compared with the traditional FR-4, aluminum substrate adopts the same thickness, the same linewidth, and can carry higher current. The aluminum substrate can withstand voltage up to 4500V, and the thermal conductivity is greater than 2.0. Generally, the aluminum substrate is the main part of LED PCB.

advantages of Aluminum-base Single-Sided LED PCB 

1. Meet ROHS requirements;
2. More suitable for SMT process;
3. In the circuit design scheme, the thermal diffusion is effectively treated, so as to reduce the operating temperature of the module, extend the service life, and improve the power density and reliability;
4. Reduce the assembly of radiators and other hardware (including thermal interface materials), reduce product volume, and reduce hardware and assembly costs;
4. Optimize the combination of power circuit and control circuit;
5. Replace the fragile ceramic substrate to obtain better mechanical durability.

Disadvantages of Aluminum-base Single-Sided LED PCB

1. High cost.
2. At present, the mainstream can only make single panel, and it is difficult to make double-sided panel.
3. It is easy to have problems in electrical strength and withstand voltage.

Construction of Single Sided PCB

Advantages of Single Layer PCB

• Ideal for simple low-density designs
• Lower cost, especially for high volume orders
• Lower probability of manufacturing issues
• Popular, common, and easily understood by most PCB manufacturers

Application of Single Sided PCB

Aluminum PCB, LED PCB used in LED lighting industry are basically Single Sided PCB.

ALTHOUGH SINGLE SIDED PCBS ARE RELATIVELY SIMPLE, THEY CAN STILL BE USED IN VERY COMPLEX DEVICES:

• Power supplies
• Relays (automotive and industrial)
• Timing circuits
• Sensor products
• LED lighting
• Radio and stereo equipment
• Packaging equipment
• Surveillance
• Calculators
• Printers
• Coffee makers
• Vending machines
• Solid state drives
• Camera systems

Single Sided PCB or Double Sided PCB?

• If you are hobbyist or students, and concerned to make PCB at home, you must know, developing single sided PCBs at home are much easier than developing double sided PCBs at home.

• As you are a manufacturer and very much interested to keep your cost down and producing a single sided PCB a most economical process. In terms of cost, producing single sided PCBs are more economical than producing double sided PCBs.

• Almost all HVAC systems make use of single sided PCBs, because they are more reliable and cost effective and don`t compromise the overall quality of the product.

• Using through hole technology in single sided PCBs still have its drawbacks and limitations because conductive layers, lines and pads stay on single side of PCB but it still is a cheap process to combine all components at one place. Multilayer PCB is also used in many applications where single sided and double sided PCBs fail to fulfill the requirements.
