Aluminum Base PCB Performance:
Better heat dissipation and conductivity: Compared with ordinary FR4 PCB, aluminum PCB has excellent heat dissipation performance. For example, Fr4 PCB with a thickness of 1.5mm will have a thermal resistance of 20-22 degrees per watt, while aluminum PCB with a depth of 1.5mm will have a thermal resistance of 1-2 degrees per watt.
There is no serious problem of thermal expansion or contraction: each substance has its coefficient of thermal expansion. The CTE of aluminum (22ppm/C) and copper(18ppm/C)is quite close. Since aluminum PCBs work well in terms of Thermal dissipation, they do not have the severe expansion or contraction issues. They work excellently and are durable and reliable.
Dimensional Stability: aluminum PCBs show dimensional stability and stable size. For example, when they are heated from 30-140 degrees, their size only had a change by 2.5%-3.0%.
Others: Aluminum PCBs can be used in power device surface mount technology. They are valid for use in circuit design because of their performance in terms of thermal expansion of circuit design. They help to prolong product shelf life and product power density. They are also extremely reliable. They can help to shrink the overall volume of the product and is also a cheaper option. They show electromagnetic shielding and high dielectric strength.

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: Are my files safe?
A: Your files are held in complete safety and security.We protect the intellectual property for our customers in the whole process.. All documents from customers are never shared with any third parties.
