Aluminum PCB, or Aluminium PCB, also called Alu PCB, is one of Insulated Metal Substrate (IMS) PCBs, and is also one of the most commonly used Metal Core PCBs nowadays.At KKPCB, we specialize in designing and manufacturing metal-core printed circuit boards (PCBs) for various applications. These applications include LEDs (light-emitting diodes), backlit LCD displays for desktops and laptops, street lights, medical and industrial monitoring systems, motor control applications, power converters, audio devices, photovoltaic components, surgical lighting tools, and high-power scanning technology. 

Advantages and Applications

Aluminium-based PCBs can consistently increase durability and long-term reliability of a final product through temperature control and associated reductions in failure rates. Aluminum designs also deliver better mechanical stability and lower thermal expansion levels than conventional PCB materials.

• Improved Product Durability
• Increased Power Density
• Increased Thermal Efficiency
• Reduced Number of Interconnects
• Lower Junction Temperatures
• Reduced PCB Size
• Eliminates Older Hardware
• Minimizes Labor Required for Assembly
• Wide Variety of Form Factors
• Minimize Thermal Impedance

Upon above advantages of Aluminum PCB, Aluminium core PCBs are widely used in LED lighting, power conversion, controllers, motor drives, rectifiers, power supply and etc.

Aluminum LED PCB with White Solder Mask

In recent years, the retail prices of Aluminum LED lights have come down significantly, while the energy efficiency and brightness of LED lights have gone up. These improvements in the technology have let to some projections of 45% growth every year for the next five years. With the growth in the LED industry, there has become a higher demand for LED PCBs and solder masks.

Solder mask is a protective coating applied to the bare printed circuit boards. Bare PCB boards are covered with mask to prevent accident solder bridging during PCB assembly and to protect the PCB from the environment. Solder masks are traditionally green color, and are expected to withstand the high temperatures present in reflow soldering for a different color like blue, red, or black arising every once in a while. The rise in LED PCB production has called for improvements in the color white and the color stability of the mask in general. The commonly used LPI solder mask colors in LED PCB are white and black, and the white solder mask is the most used for achieving a high brightness and perfect light reflection. White LED PCB ensures not go dark, and not to affect the color temperature of the LED SMDs. While, it also helps improve the lifespan for the LED light applications.
