Often used in LED lighting products, there are two sides, the white side is soldered to the LED pin, and the other side is in the form of aluminum, generally the thermal conductive paste is applied and the heat conductive portion is contacted.
1. Compared with the traditional FR-4, the aluminum based PCB can minimize the thermal resistance and make the aluminum substrate have excellent thermal conductivity. Compared with the thick film ceramic circuit, its mechanical properties are extremely excellent.
2. Meet RoHs requirements.
3. More suitable for SMT process.
4. Extremely effective treatment of thermal diffusion in the circuit design, thereby reducing module operating temperature, extending service life, increasing power density and reliability.
5. Reduce the assembly of heat sinks and other hardware (including thermal interface materials), reduce product size, reduce hardware and assembly costs; optimize the combination of power and control circuits.
6. Replaces fragile ceramic substrates for better mechanical durability.
Aluminum based PCB are generally stored in a dark, dry environment. Most aluminum based PCB is prone to moisture, yellowing and blackening. Generally, they should be used within 48 hours after opening the vacuum package.

According to the Japan Electronics Packaging Circuits Association (JPCA), Japanese PCB production saw significant growth in January 2015. The total output, including rigid PCBs, flexible PCBs (FPC), and module substrates, increased by 3.2% year-over-year. Flexible PCBs led the surge with a remarkable 23.1% rise in production. Major suppliers like Ibiden and Nippon Mektron contributed to this upward trend.
In the world of electronics, the choice of substrate material for printed circuit boards (PCBs) plays a crucial role in determining the overall performance, reliability, and efficiency of the system. Among the various options available, aluminum PCB (Aluminum Based PCB or Aluminum Substr
In the rapidly evolving world of electronics, the demand for more compact, faster, and reliable devices has skyrocketed. This technological leapfrog has necessitated the development of advanced manufacturing techniques and materials, with MultiLayer Printed Circuit Boards (PCBs) emerging as a corner
Double Side PCB, also known as Double-sided PCB or Double-sided Circuit Board, is a commonly used electronic component that features circuit traces on both sides of the board. This design allows for the integration of two distinct circuits within a single board, offering advantages in terms of space
Ceramic PCBs, also known as ceramic printed circuit boards, are a type of circuit board that utilizes a ceramic base material instead of the traditional fiberglass. These specialized PCBs offer a range of benefits and are particularly well-suited for applications that require high thermal conductivi
IntroductionFlexible circuit boards have gained popularity in various industries due to their unique characteristics and applications. However, a common question that arises is whether flexible circuit boards are as reliable as their rigid counterparts. In this article, we will explore the reliabili
