The designs of electronic devices and systems are being continuously improved by becoming smaller in size and faster in communication speed. The potential risk associated with these specific design improvements will be an increase in power density and, consequently, a greater risk of thermal problems and failures. At the same time, the prevailing use of circuit boards integrated with power devices such as motor controllers and drivers, light emitting diode (LED) lighting modules, power supplies and amplifiers, and regulators for TV, etc., drive to the use of aluminum PCBs instead of traditional FR4 or CEM3 PCBs because of the ability to efficiently dissipate heat away from the components. It has many The aluminum PCB has many benefits such as
• Dissipation of heat without using additional heatsinks;
• Mechanically rigid, increasing the physical strength of the assembly;
• Reduces the effect of thermal stress on all components, increasing life and durability;
• Improved thermal conduction leading to versatility in component and tracking layout enabling PCB dimensions to be reduced; and
• Reduces component operating temperatures, improving reliability.
