white melamine board for aluminium backed pcb
aluminium backed pcb
Aluminum-backed PCBs are the same as the copper-backed ones. The only difference is the use of either copper or aluminum substrate board. Aluminum-backed boards characterized as having a thermal clad layer. that helps it to disperse heat a lot better.
This ability is what makes this type of PCB to be an excellent solution for high power applications. Besides dispersing heat, the layer also has cooling components. These parts are what allow the board to have increased performance.
Aluminum based PCB, also named Aluminium PCB, metal clad (MCPCB) PCB. insulated metal substrate(IMS or IMPCB) PCB. conductive PCBs, etc. It is generally including single layer. double layer and multi layer.
aluminium drill bit PCB specification
The power device surface mounting on circuit layer. it is suited for the mounting of high power light emitting diodes (LEDs). dissipating the heat generated by power devices.
Aluminum based PCB used:

drilling aluminium advantages
Heat dissipation is superior to standard FR-4 constructions.
The dielectrics used are 5 to 10 times as conductive as conventional epoxy-glass. and a tenth of the thickness
Thermal transfer more efficient than a conventional rigid PCB.
Lower copper weights than suggested by the IPC heat-rise charts can used.
the most important advantage of aluminum-backed PCBs. it can help heat to dissipate a lot better and more . Aluminum known to be an excellent material. for dispersing heat away from the circuit board’s most important parts. With aluminum material. the heat dissipated in the open air that helps to avoid causing severe damage.
Aluminum has a longer life than any other materials found. inside the circuit board, such as the insulation and copper foil. With that, you can expect that aluminum PCBs won’t be peeling away anytime soon. It means you can save on buying another PCB for your applications. since it can last longer than other circuit boards.
If there is any material that you can trust. will not have any adverse effects on the environment – that is aluminum. This material is not only non-toxic but also a recyclable material. Thanks to that, it is the number choice of many engineers who are looking for eco-friendly PCB options.
Another of the reasons why many engineers choose aluminum-backed PCBs is. because it is an inexpensive option. The material is easy to find that contributed to the low cost price of this type of printed circuit board.
