Hi! In this video I want to introduce and explain the new aluminum PCBs, how they are made and for what applications they are designed (not for standard PCB) Aluminum PCBs are ideal for situations when thermal heat dissipation requirements are very high. They are more effective at directing thermal energy away from PCB components and are used more than ever for applications of high power and high thermal heat dissipation... Like LED applications, including traffic lights, automotive lighting and general lighting.Unfortunately, as they are made, these PCBs have the drawback that they can only be single layer PCB and with SMD components
HOW ALUMINUM PCBs ARE MADE?
Aluminum printed circuit boards are also known as metal base PCBs and are comprised of metal based laminates covered by copper foil circuit layers. They are made of alloy plates that are a combination of aluminum, magnesium and silumin. They have anexcellent electrical insulation, good thermal potential and high machining performance, and they differ from other PCBs in several important ways like:
- These PCBs have a base layer that consists of an aluminum alloy substrate (Aluminum Layer)
- The thermal insulation layer that is an important component of the PCB. It contains a ceramic polymer that has excellent viscoelastic properties, great thermal resistance and defends the PCB from any stresses.
- The circuit layer that contains the copper foil for the PCB tracks (Circuit Copper Layer)
- The dielectric layer of insulation absorbs heat as current flows through the circuits. This is transferred to the aluminum layer, where the heat is dissipated.
In summary, the advantages of this type of PCB are:
- Less Expensive
- Ambient Friendly
- Heat transfer
- Sturdy and for voltages higher than 3000 volts
- Lightweight (compared to other metals)
HOW ABOUT STANDARD COMPONENTS?
It is not possible to use this type of PCB with standard components, but only with SMD / SMT components which are positioned and soldered on the same layer.Because as a result of the internal contact of the holes with the aluminum, all the pins of the components will be short-circuited with each other :(
The "Aluminum Vu-Meter" PCB was made only for the realization of this video, but as I explained it is not working. Made aluminum PCB only for single layer projects, with SMD SMT components
After trying the excellent service offered by JLCPCB I recommend it, the quality of the PCB is high, customer service is always available and professional, the time of realization is short and the delivery of PCBs is by express courier. JLCPCB is a great place to get hight quality custom circuit boards at an extremely low price, you can buy 5 PCB Boards (Any Color) for 2$ !!!
For any other questions you can ask me for explanations in the video comments:)
