Structure and feature of Aluminum PCB Aluminum-based printed circuit boards (PCBs) are specialized metal-based boards known for their excellent thermal conductivity, electrical insulation, and mechanical properties. They are widely used in applications such as LEDs, automotive electronics, air conditioning, and high-power modules. The structure of an aluminum PCB consists of three layers: a copper circuit layer, a dielectric thermal conductive layer, and a metal substrate, typically aluminum or copper. Aluminum PCBs offer several benefits, including ease of use with surface mount technology (SMT), improved thermal diffusion, lower operating temperatures, increased power density and reliability, and reduced hardware and assembly costs. They are also more mechanically durable compared to ceramic PCBs.
