Aluminum PCB

Aluminum PCB

Aluminum PCBs have a base made of a dielectric metal and a bonded copper circuits layer, which improves heat transfer and helps components cool off while removing challenges related to handling delicate ceramics. When it comes to fulfilling all client expectations, an electronic manufacturing firm strives to be the top aluminium PCB maker. The metal core may be made entirely of metal or may include a fibreglass and aluminium composite. Although they can be double sided, aluminium PCBs are mainly single sided. In ems electronics manufacturing of multilayer aluminium PCBs is quite challenging.

Performance of Aluminum PCB

  1. Thermal Dissipation

Common PCB substrates like FR4 and CEM3 are poor thermal conductors. Ems electronic components will fail at high temperatures if the heat generated by equipment cannot be dispersed in time. These thermal dissipation issues can be resolved by using aluminium substrates.

  1. Thermal Expansion

In order to alleviate the issue of expansion and contraction of elements on printed circuit boards made of various materials, aluminium substrate PCB can effectively address the thermal dissipation issue. This increases the robustness and dependability of the entire machine and electronic items. Aluminum substrate, in particular, can address the thermal contraction and expansion issues associated with SMT (surface mount technology).

  1. Dimensional Stability

Printed circuit boards with aluminium substrates appear to be more stable than printed circuit board with insulating materials. 

  1. Other Performance

A board pcb with an aluminium substrate has a shielding effect and an alternative to brittle ceramic substrate. Additionally, the use of aluminium substrate enhances physical and heat resistance while lowering labour and production costs.


An aluminium PCB increases the stability and longevity of an LED gadget. Aluminum substrates are used in domestic lighting, stop lights, and street lighting. In power converters, they allow electronic regulation & current switching. It is simple to mine and purify aluminium because it may be found in a range of climates. As a result, compared to other metals, the costs are much cheaper. In turn, this implies that it costs less to produce goods using these metals. Ceramic or fibreglass bases are unable to give a product the strength and durability that aluminium can. Aluminum is a reliable base material that really can lessen unintentional damage during production, handling, and regular use.


Since aluminium can really transmit heat away from critical parts, the damage it may otherwise do to the circuit board is reduced. Greater durability: Unlike ceramic or fibreglass bases, aluminium gives a product strength and durability.
