Aluminium PCBs – All That You Should Know - Miracle Electronics

1. Aluminium PCBs – All That You Should Know - Miracle Electronics With PCBs, it’s no big deal connecting various components on the board, provided you know how to do it. And, as a layman, you probably wouldn’t know, which is why there are professionals, like Miracle Electronics, to take care of it, by bringing to you a PCB assembly from India, perfectly suited to your needs. If you think “Copper” when you think “PCB”, it’s quite natural because we have always associated only copper with PCBs. But, this isn’t true. Not all PCBs are always made of copper.There’s another impressive metal that is doing the rounds in the PCB industry since a good amount of time; and that is Aluminum. Aluminium PCBs are a great choice for engineering applications as they are ideal for heat control and maintenance. Here’s more to unravelling the benefits and performance of Aluminum PCBs.

2. What are Aluminum PCBs? Aluminum PCBs are nothing new. They came into existence back in the mid-70s, but they are gaining popularity now, being used on a large scale, especially due to their high conductivity capabilities. Aluminum PCBs have four basic structures – copper foil layer, dielectric layer, aluminium base layer, and aluminium base membrane. Copper foil layer– This circuit layer comes with a copper foil, weighing anywhere between 25 to 250 grams, depending upon the requirement. Dielectric layer– This layer is mainly for absorbing heat when current flows through the PCB, moving to the aluminium layer, where the heat spreads. Aluminum base layer– This layer consists of aluminium substrates, making it viscoelastic and highly conductive thermally. Aluminum base membrane– This layer is made from aluminium alloy, and is responsible for keeping the surface of the aluminium from etching and scratching. Types of Aluminum PCBs Multilayer Aluminum PCBs– These PCBs have multiple layers of thermally conductive dielectric materials.

3. Flexible Aluminum PCBs– Polyimide resin is used here, integrated into ceramic filters to bring quality electrical insulation, thermal efficiency, and high flexibility. Through-hole Aluminum PCBs– These PCBs have a single layer of Aluminum pre-drilled and back-filled, after which the thermal materials are laminated onto the Aluminum, and then drilled and passed through clearance. Hybrid Aluminum PCBs– Here, non-thermal materials get refined and processed separately, after which they get applied to thermal components with an aluminium bed, providing more efficient thermal conductance. Characteristics of Aluminum PCBs Lightweight– Aluminum is very light in weight, thus making Aluminum PCBs lightweight too, but with durability and flexibility intact. Dimensional stability– Aluminum PCBs are comparatively firmer and stable, even at high temperatures of 150°C; and even if it changes, the change is only about 2.5-3%. Thermal dissipation– There is effective heat dissipation with Aluminum PCBs, with no thermal contraction or expansion issues; thus improving the sturdiness and quality of electronic appliances.

4. Affordability– Aluminum PCBs are quite affordable as compared to their counterparts, because the metal itself is affordable, and the cost of production and labour is also significantly reduced. Environment-friendly– Aluminum is non-toxic and recyclable; thus making the PCBs made from the metal absolutely environment-friendly. Applications of Aluminum PCBs With Aluminum PCBs being stable, durable, affordable, and well- performing, it gains prominence in a number of applications like – LED circuit boards– When Aluminum PCBs are used in LED circuit boards, they pose the lowest possible operating temperature, but high brightness and maximum life, while also saving energy. Computers– Computers are known to release lots of heat, which may ultimately damage the device. But, with Aluminum PCBs, this heat generation can be considerably reduced. Automobiles– Another application is the automobile industry, which uses Aluminum PCBs mainly because it reduces the heat generated. Audio equipment– Aluminum PCBs move heat away from vital components, thus proving to be the best solution for tight tolerance and high power; making them apt for audio applications.

5. With all the best characteristics Aluminum PCBs possess, there is no doubt why they are becoming popular in so many industries.
