Thermal Expansion OSP 3mil Round LED PCB Board For LED Lighting
Customize PCB Aluminium mcpcb led printed circuits board for LED lighting
Performance of Aluminum PCB:
1. Thermal Dissipation
Common PCB substrates, such as FR4, CEM3 are poor conductors of thermal. If the heat of electronic equipments cannot be distributed in time, it will result in high temperature failure of electronic components. Aluminum substrates can solve this thermal dissipation problem.
2. Thermal Expansion
Aluminum substrate PCB can effectively solve the thermal dissipation problem, so that the thermal expansion and contraction problem of components on printed circuit boards with different substances can be alleviated, which improves the durability and reliability of whole machine and electronic equipments. In particular, aluminum substrate can solve the SMT (surface mount technology) thermal expansion and contraction problems.
3. Dimensional Stability
Aluminum substrate printed circuit board has apparently higher stability than the insulating material of the printed circuit board. When heated from 30 ° C to 140 ~ 150 ° C, the dimensional change of aluminum substrate is only 2.5 ~ 3.0%.
4. Other Performance
Aluminum substrate printed circuit board has shielding effect, and can alternative brittle ceramic substrate. Aluminum substrate also helps to improve the heat resistance and physical properties and reduce production costs and labor.

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: How can I get a sample to check your quality?
A: After price confirmation,you can place orders for samples for your testing and evaluation.
