Aluminium PCB, also named aluminum base PCB, metal clad (MCPCB) PCB. It is generally including single layer, double layer and multi layer. Normally aluminum PCB consists of line layer, insulating layer, metal substrate.
Advantages of Aluminum PCB:
The heat dissipation afforded by this construction is dramatically superior to standard FR-4 constructions. The dielectrics used are typically 5 to 10 times as thermally conductive as conventional epoxy-glass and a tenth of the thickness resulting in thermal transfer exponentially more efficient than a conventional rigid PCB. This is so effective that lower copper weights than suggested by the IPC heat-rise charts can be used.
Aluminum PCB has good thermal Conductivity, and for aluminum base material can support strong enough electric current compared with FR-4 material. Aluminum PCB use SMT is very effective to deal with heat diffusion. And can reduce product volume, and then decrease the cost of hardware and assembly. Lastly, it can lower the product operating temperature and then lengthen its service life.
Here is a technological process of producing the aluminum PCB:
1) Board cut
3) Wet/dry film imaging
4) The acidic/alkaline etching
5) Silkscreen, solder mask
6) V-cut, ROT
7) Testing, OSP
8) FQC-FQA-packing- shipment
Applications of Aluminum PCB:
Automotive: Head lights, Tail light assemblies, Running side markers, Dash board, interior lighting.
Military: Head lights, Running lights, Spot lights, Signal beacons, High power flash lights, Power converters, Power supplies, Power transmission systems, Ignition systems, Power distribution products.
Aerospace: Aircraft landing lights, Running lights, Cabin mood lighting systems, Spot light and general lighting.
Consumer: Street lighting, Traffic control lighting, interior building lights, Landscape lighting, Camping gear.
Medical: Operating room lighting, surgical lighting tools, High power scanning technology, Power converters.
Wonderful PCB Limited has a decade of producing Aluminum PCB, from 0.4MM to 3.2MM thickness. Normally we suggest the heat transfer rate to be: 1,0W/m*K or 1,5W/m*K.
