Nowadays, with the growing demand for smaller packaging of electronics and increased functionality, PCB is getting more and more popular. Therefore,making quality printed boards are now the focus of manufactures of most of the electronic applications. Nevertheless,over the last years,Aluminium PCBs have become the first choice for the electronic items. Obviously,it is now more popular than the conventionally used polyimide materials. Why is it the preferred choice? The reasons have been discussed here.
Firstly,
Property Of Flexibility. Although the metal aluminium based pcb is
light weight, its strength can be increased as required for any specific
application by changing its alloys composition. This gives it increased
strength and makes it mechanically rigid, which is much needed for a
flexible circuit board. This metal is also known to be ductile. This
enables the PCB manufacturer to process this metal as required in molten
state. After the product solidifies, it becomes strong and lasts for
long.
And then, properties of conduction is also necessary. For
manufacturing a printed circuit board it is important to get a base
which has a very good conductivity for both heat and electricity.
Aluminium scores here and serves as the best base for making Metal core
PCBs which assist in heat dissipation with no extra heat sinks. This
property further helps in reducing the thermal stress on the parts which
in turns helps in increasing life and durability. This way the
manufactures are able to reduce the overall temperature of the
components while operating and improve the reliability of the board. The
thermal conduction property of aluminium has lead to versatility of the
parts. PCB dimensions have also reduced due to the effective layout
tracking. Aluminium also reduces the impact of the electromagnetic
interference and acts as shield to electric field to the electronic
parts. Its property of eliminating thermal stress has also made it the
metal of choice for power transmission lines globally.
Apart from
conduction and flexibility, it also has some other fatures including
anti corrosive which makes it last through a wide range of environmental
conditions and non-toxic and recyclable features which make it a safe
choice for PCBs. At present,in a range of areas from kitchen to
commercial sectors, aluminium is being used. For instance, this metal is
used for making foil for packing of eatables, making of ladders etc. In
a word,the scope of reuse of aluminium is very large. Aluminium PCB is
considered cost effective because it's long life and reliability. More
