94V0 LED Printed Circuit Board
Aluminum Clip Board Stand PCB circuit board 94V0 Assembled LED Board
Thermal Dissipation:the performance of aluminum PCBs while dissipating heat is quite well as compared to ordinary FR4 PCBs. For example, a FR4 PCB that is 1.5mm thick will have thermal resistance of 20-22 degrees per watt whiles a aluminum PCB 1. 5mm thick will have a thermal resistance of 1-2 degrees per watt.
Thermal Expansion: each substance has its own 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 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 effective for use in circuit design because of their performance in terms of thermal expansion of circuit design. They help to prolong products 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.
Classification of Aluminum PCBs: Aluminum PCBs are essentially divided into three categories.
1: Universal Aluminum PCB: the dielectric layer used here is made up of epoxy glass fiber pre-preg.
2: High Thermal-Conductive Aluminum PCB:the dielectric layer is made up of epoxy resin. The resin used must have high thermal conductivity.
3: High-frequency Aluminum PCB:the dielectric layer is composed of polyolefin or polyimide resin glass fiber pre-preg.
