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.

In the ever-evolving world of electronics, one technology has been quietly making waves and transforming the landscape of printed circuit boards (PCBs). Ceramic PCBs, also known as ceramic hybrid circuit devices, have emerged as a game-changer in the industry, offering a host of advantages over traditional materials.
When it comes to installing low voltage LED lighting, one of the most critical decisions you'll make is selecting the appropriate gauge wire. The wire gauge affects the performance, safety, and efficiency of your lighting system.
In the world of electronics, printed circuit boards (PCBs) are the backbone of virtually every device. Among the various types of PCBs, heavy copper PCBs stand out due to their unique properties and applications.
According to JPCA statistics for July 2015, Japan's printed circuit board (PCB) production, including rigid, flexible, and IC substrate PCBs, increased by 16.8% year-over-year, reaching 1.368 million square meters. Sales volume grew by 12.2% to 47.028 billion yen. Flexible PCB production soared by 103.8%, marking the 11th consecutive month of growth, while IC substrate PCB production rose by 7.1%. Conventional FR4 PCB production remained steady, ending a six-month decline. For the first seven months of 2015, overall PCB production in Japan grew by 0.6%, with total sales increasing by 8.2%.
A well-structured PCB layout begins with a carefully designed schematic. A thoughtful schematic with clear signal flow and detailed information can greatly improve the final PCB design. To enhance schematics, designers should include waveforms, mechanical details, trace lengths, and component placement specifications. Additional information like tuning details, thermal data, and controlled impedance lines can further aid engineers and technicians. As devices become more complex and miniaturized, PCB designers face challenges in areas such as FPGA integration, thermal management, and information handling. Advances in PCB prototyping tools and design software help address these growing challenges.
Adding text and identifiers to PCBs is essential for board identification and component marking. This is done using a silk screen generated by PCB design software after the board's main manufacturing processes are complete. Standard colors include green, black, white, and yellow, with non-standard options available at higher costs. Legend printing methods include manual screen-printing for larger line widths, Liquid Photo Imaging (LPI) for higher accuracy, and Direct Legend Printing (DLP) for maximum precision but at greater expense. Designers must follow IPC requirements for manufacturer marks and should avoid placing legends over circuit pads. Ensuring proper alignment, color selection, and considering manufacturing tolerances can help reduce costs.
