Aluminum PCB
Aluminum PCBs consist of dielectric metal substrates and bonded copper circuit layers that produce excellent heat transfer, helping to cool components while eliminating problems related to the management of fragile ceramics.
When exceeding all customer expectations, Alcanta PCB is committed to becoming the best Aluminium PCB manufacturer.We provide a variety of conductive and conductive interface pads, thermal gap fillers, thermal phase change materials and thermal insulation materials, as well as specialized equipment for mass production.
Aluminum-based PCB can continuously improve the durability and long-term reliability of the final product through temperature control and corresponding failure rate reduction.Aluminum design also offers better mechanical stability and lower thermal expansion than other available materials.
Aluminum PCB Layer：
Aluminum PCB is a unique layered system composed of the following layers.
- Circuit layer:Printed circuit foil, 1 oz to 5 oz thick.
- Dielectric layer:Dielectric layers can have many different choices that provide electrical isolation with minimal thermal resistance.It is also used to bond the circuit layer to the base material.Each specific dielectric has its own UL certification.Please refer to the list below to understand the various materials in our stock to ensure a variety of options for fast delivery.
- The basic level:The base layer is usually aluminum, but it can also be copper.Although there are many thickness options, the most common thickness is 0.040 inches (1.0mm).
