thermal conductivity

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. Read More

Aluminum's properties, including ductility and adaptability, allow for flexible PCB design and size reduction while maintaining reliability. Aluminum PCBs, also known as "metal core printed circuit boards," help reduce component temperatures and improve overall durability. The main technical requirements for aluminum PCBs involve size, cosmetic appearance, and functional characteristics such as peel strength, surface resistivity, breakdown voltage, dielectric constant, thermal resistance, and flammability. The popularity of aluminum PCBs among manufacturers like SysPCB in Shenzhen, China, is due to these advantages, leading to increased use in various electronic applications. Read More

Aluminum PCBs, compared to traditional FR4 PCBs, can carry higher current with the same thickness and line width. The key component of aluminum PCBs is the insulation layer, which provides adhesion, insulation, and thermal conductivity. The structure of a single-sided aluminum PCB includes a circuit layer, an insulating layer, and a metal layer. For more complex applications, there are two-layer and multilayer aluminum PCBs. The insulation layer's thermal conductivity is crucial for heat dissipation, which helps reduce device operating temperatures, increase power load, reduce volume, extend service life, and improve power output.

The text discusses the revenue and market trends for a listed PCB factory in Shenzhen, China. The factory maintained a revenue level of 1.25 billion yuan in early 2015 and experienced growth in the energy-efficient LED lighting market. Aluminum PCBs, which account for 20% of revenue due to their excellent thermal conductivity, are increasingly in demand for LED lighting and flat panel displays. The proportion of LED-related PCBs in total revenue is expected to rise, driven by the growing global demand for LED bulbs, which is predicted to increase by 53% in 2015. The third quarter's revenue growth is attributed to the rising demand for aluminum PCBs in both LED lighting and LCD panels. Read More
