Those tech savvies that are looking for a special PCB will appreciate the aluminum board because of its unique properties and reasonable price. The higher the expectations go the higher the costs, but the good thing is that no matter what are your PCB needs, they can be easily met by these remarkable items. Insulation thickness is very important and knowing the minimum and maximum is critical, because you need your equipment to function at full potential, without breaking down.
Speaking of which, every aluminum board has a breakdown voltage and in this case, the minimum is more important, just like the solder resistance. Depending on the environments that it is meant to be used in, fire and water can raise specific problems and knowing the flammability and water absorption will save you a lot of money and energy. On the insulation layer, it is also possible to determine the thermal connectivity, which is one of the major criteria when choosing a PCB.
The name can be a bit deceiving, because the aluminum board is not made entirely from this material, with copper playing a central role. This is why you need to know exactly, which is the copper and aluminum material thickness and the good thing is that you can easily find any proportions that you need. The based layer thickness is important and depending on what you need, you can request a single or double side, without having to spend too much extra for the latter version.
