<p><a href="https://www.rocket-pcb.com/aluminum-pcb" rel="noopener noreferrer" target="_blank"><strong>Aluminum-backed PCBs</strong></a> have many advantages,including:</p><p>• Low cost. Aluminum is one of the most abundant metals on Earth, making up 8.23% of the planet's weight. Aluminum is easy and inexpensive to mine, which helps to cut expenses in manufacturing process. Thus, building products with aluminum is less expensive.</p><p><br></p><p>• Environmentally friendly. Aluminum is non-toxic and easily recyclable. Manufacturing printed circuit boards out of aluminum is also a good way to conserve energy.</p><p><br></p><p>• Heat dissipation. Aluminum is one of the best materials available for dissipating heat away from crucial components of circuit boards. Instead of dispersing the heat out into the rest of the board, it transfers heat out into the open air. Aluminum PCB cools faster than an equivalent-sized <a href="https://www.rocket-pcb.com/heavy-copper-pcb" rel="noopener noreferrer" target="_blank"><strong>copper PCB</strong></a>.</p><p><br></p><p>• Material durability. Aluminum is far more durable than materials like fiberglass or ceramic, especially for drop tests. The use of sturdier base materials helps reduce damage during manufacture, shipping and installation.</p><p><br></p><p>All of these advantages make <strong>Aluminum PCBs</strong> an excellent choice for applications require high outputs of power within very tight tolerances, including Traffic lights, Automotive lighting, Power supplies, Motor controllers and High-current circuitry.</p><p><br></p><p>In addition to those major areas of use, aluminum-backed PCBs can also be used in applications that require a high degree of mechanical stability or where the PCB might be subject to high levels of mechanical stress. They are less subject to thermal expansion than a fiberglass-based board, meaning that the other materials on the board, such as the copper foil and insulation, will be less likely to peel away, further lengthening the lifetime of the product.</p><p><br></p><p>Throughout the years, PCBs have evolved from the simple <a href="https://www.rocket-pcb.com/single-double-sided-pcb" rel="noopener noreferrer" target="_blank"><strong>single-layer PCBs</strong></a> used in electronics such as calculators to more complex systems, such as a high-frequency Teflon design. PCBs have found their way into almost every industry on the planet, from simple electronics like lighting solutions all the way up to more complex industries like medical or aerospace technology.</p><p><br></p><p>The evolution of PCBs has also pushed a development in PCB building materials: no longer are PCBs built solely out of fiberglass-backed copper foil. New construction materials include aluminum, Teflon and even bendable plastics. Bendable plastics and aluminum, in particular, have spurred the creation of products like rigid-flex and aluminum-backed PCBs to address the common problems associated with many industries.</p>
