Aluminium PCBs All That You Should Know -
Miracle Electronics
With PCBs, its no big deal connecting various
components on the board, provided you know how
to do it. And, as a layman, you probably
wouldnt know, which is why there are
professionals, like Miracle Electronics, to take
care of it, by bringing to you a PCB assembly
from India, perfectly suited to your needs.
If you think Copper when you think PCB, its
quite natural because we have always associated
only copper with PCBs. But, this isnt true. Not
all PCBs are always made of copper. Theres
another impressive metal that is doing the rounds
in the PCB industry since a good amount of time
and that is Aluminum. Aluminium PCBs are a great
choice for engineering applications as they are
ideal for heat control and maintenance. Heres
more to unravelling the benefits and performance
of Aluminum PCBs.

What are Aluminum PCBs? Aluminum PCBs are nothing
new. They came into existence back in the
mid-70s, but they are gaining popularity now,
being used on a large scale, especially due to
their high conductivity capabilities. Aluminum
PCBs have four basic structures copper foil
layer, dielectric layer, aluminium base layer,
and aluminium base membrane. Copper foil layer
This circuit layer comes with a copper foil,
weighing anywhere between 25 to 250 grams,
depending upon the requirement. Dielectric
layer This layer is mainly for absorbing heat
when current flows through the PCB, moving to
the aluminium layer, where the heat
spreads. Aluminum base layer This layer
consists of aluminium substrates, making it
viscoelastic and highly conductive
thermally. Aluminum base membrane This layer
is made from aluminium alloy, and is responsible
for keeping the surface of the aluminium from
etching and scratching.
Types of Aluminum PCBs
Multilayer Aluminum PCBs These PCBs have
multiple layers of thermally conductive
dielectric materials.

Flexible Aluminum PCBs Polyimide resin is used
here, integrated into ceramic filters to bring
quality electrical insulation, thermal
efficiency, and high flexibility. Through-hole
Aluminum PCBs These PCBs have a single layer
of Aluminum pre-drilled and back-filled, after
which the thermal materials are laminated onto
the Aluminum, and then drilled and passed
through clearance. Hybrid Aluminum PCBs Here,
non-thermal materials get refined and processed
separately, after which they get applied to
thermal components with an aluminium bed,
providing more efficient thermal conductance.
Characteristics of Aluminum PCBs
Lightweight Aluminum is very light in weight,
thus making Aluminum PCBs lightweight too, but
with durability and flexibility
intact. Dimensional stability Aluminum PCBs
are comparatively firmer and stable, even at
high temperatures of 150C and even if it
changes, the change is only about
2.5-3. Thermal dissipation There is effective
heat dissipation with Aluminum PCBs, with no
thermal contraction or expansion issues thus
improving the sturdiness and quality of
electronic appliances.

Affordability Aluminum PCBs are quite
affordable as compared to their counterparts,
because the metal itself is affordable, and
the cost of production and labour is also
significantly reduced. Environment-friendly
Aluminum is non-toxic and recyclable thus
making the PCBs made from the metal absolutely
environment-friendly. Applications of Aluminum
PCBs With Aluminum PCBs being stable, durable,
affordable, and well- performing, it gains
prominence in a number of applications like
LED circuit boards When Aluminum PCBs are
used in LED circuit boards, they pose the lowest
possible operating temperature, but high
brightness and maximum life, while also saving
energy. Computers Computers are known to
release lots of heat, which may ultimately
damage the device. But, with Aluminum PCBs, this
heat generation can be considerably
reduced. Automobiles Another application is
the automobile industry, which uses Aluminum
PCBs mainly because it reduces the heat
generated. Audio equipment Aluminum PCBs move
heat away from vital components, thus proving to
be the best solution for tight tolerance and
high power making them apt for audio
applications.
