Structure of Aluminum PCB:
Aluminum PCBs are aluminum based CCLs (CCL is a type of base material of PCBs). AluminumPCBs are actually quite similar to FR4 PCBs. The basic structure of Aluminum PCBs is four layered. It consists of a layer of copper foil, a dielectric layer, an aluminum base layer and aluminum base membrane.
Copper Foil Layer: the copper layer used is relatively thicker than normal CCLs ( 1oz-10oz). A thicker layer of copper means a larger current carrying capacity.
Dielectric Layer: the Dielectric layer is a thermally conductive layer and is around 50μm to 200μm thick. It had a low thermal resistance and it suitable for its application.
Aluminum Base: The third layer isthe aluminum base which is made up of aluminum substrate. It has a high thermal conductivity.
Aluminum Base Membrane Layer: Aluminum base membrane is selective. It has a protective role by keeping the aluminum surface safe from scraping and unwanted etching. It is of two types i.e. Lower than 120 degree or around 250 degrees (anti high temperature).
FAQ:
Q1: How about your supply capacity?
A: For PCB board, you need to prepare files of Gerber file,it should including RS274X,ODB++, DXF, PCB, PCBDOC etc formats.For PCBA(PCB with soldered components), except the file for PCB, you also need to prepare the BOM list (components list), Pick and Place file(txt format), real sample picture or 3D PDF version file etc.
Q2: How about the Shipping cost?
A: The shipping cost is determined by the destination, weight, packing size of the goods. Please let us know if you need us to quote you the shipping cost.
Q3: What are the main products of your PCB/PCBA services?
A: Industrial control, Automotive, Medical Equipment, Communication Electronics, Security Devices.
