Aluminum printed circuits contain a thin layer of thermally conductive dielectric material that transfers heat.
There are many names for these products: Aluminum clad, aluminum base, Metal clad printed Circuit Board (MCPCB), Insulated Metal Substrate (IMS or IMPCB), Thermally conductive PCBs, etc … but they all mean the same thing and work the same way.
A single-layer or single-sided PCB is made from a single layer of base material or substrate covered with a thin layer of copper. In addition to the copper part, a protective mask called “Solder” is usually applied, normally followed by a last silkscreen mask called “Symbology” which is used to indicate all the components of the circuit.
Single-sided PCBs are simple to manufacture with a relatively low cost for this, where possible, they are often used in the creation of circuits for domestic appliances and large-scale commercial equipment.
2-layer circuits (also known as Double-sided, Dual-Side or DSPT circuits) are the entry port for higher technology applications. They allow you to make PCBs with higher density with closer slopes, alternating between the top and bottom layers using Vias holes. Today, double-sided circuit boards are perhaps the most popular type of PCB produced in the industry.

Multilayer PCB is a printed circuit board that has more than two layers.
Unlike a double-sided PCB that has only two conductive layers of material, all multilayer PCBs must have at least three layers of conductive material enclosed in the center of the material.
