Aluminum PCB

The LED lighting industry is expected to experience significant growth in Guangdong Province, with an anticipated installed capacity of 1.1 million LED lights by 2027, driven by government policies and the region's strong Aluminum and Fiber glass PCB industry. International lighting companies have introduced low-cost LED products to replace incandescent lamps, which are more energy-efficient, using 90% less electricity compared to traditional bulbs and 50% less compared to high-pressure sodium lamps. In the next two years, over 600,000 LED street lamps will be installed in the Pearl River Delta. LED lighting is also poised to penetrate indoor illumination markets, with 30% market share expected by 2015. To ensure quality, the Guangdong Provincial Science and Technology Department is working to establish standards and plans to offer subsidies to institutional investors to promote widespread adoption of LED lighting.

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

COB, or Chip-on-Board, is a semiconductor assembly technology that directly attaches microchips to a substrate, bypassing traditional IC packaging. Substrates can be made of ceramic or flex materials, offering excellent dielectric and thermal properties. The COB manufacturing process involves die attachment, wire bonding, and encapsulation of die wires. Variants like FCOB (Flip-Chip-on-Board) eliminate wire bonding by directly connecting chips to the board, providing additional protection against chemical and mechanical damage through underfilling. COB technology differs significantly from conventional aluminum PCB manufacturing processes in terms of die attach, wire bonding, and encapsulation techniques. 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
