What are 4 layers of MCPCB?

A 4-Lather MCPCB (Metal Core Printed Circuit Board) is a multilayer circuit board with superior thermal management capabilities, displaying four conductive copper layers bound to aluminum or copper substrate. This structure includes the upper layer for components, two inner layers for the stomach, and the lower layer attached to the metal core through the thermal conductive dielectric material.

This design efficiently transferring heat from the power component (such as high intensity LEDs) through the dielectric layer into the base of the metal, preventing excessive heat while maintaining electrical insulation. Multilayer configuration allows complex circuit design while the metal substrate increases mechanical stability and heat dissipation (usually 8-10x is better than a standard PCB).

How do 4 MCPCB layers for UVC LEDs reduce the risk of thermal escape?

• Thermal conductivity of the high efficiency of the metal substrate: Aluminum or copper is used as a basic ingredient, and thermal conductivity is much higher than the traditional FR4 board (aluminum is around 237 W/Mâ · K, copper of around 401 W/Mâ · K), which can quickly transfer heat produced by UVC LEDs from the Chip intersection area to the substrate to avoid excessive local temperatures.
• Low thermal resistance insulation layer design: The thin layer of high-performing isolation media (such as polymers filled with ceramics) is embedded between metal substrates and copper circuit layers, and its thickness is controlled at 50-100îîief
• Thermal diffusion effects of multi-layer copper layers: The circuit layer uses 1-2 oz copper foil (around 35-70îief), and heat diffusion tissue is formed through a large area copper coating design, which spreads heat concentrated in the LED area horizontally to the entire surface of the PCB, reducing the density of heat sources.
• Thermal layout through a dense array: Coated copper through a hole with a diameter of 0.3-0.5 mm is arranged below and around the LED package, with a distance of 1-2 mm to form a vertical heat conduction channel, directly connecting the upper circuit layer and metal substrate, shortening the heat conduction path.
• Rigid structure prevents thermal deformation: The high stiffness of the metal substrate (aluminum Young modulus is around 70 GPA) can effectively inhibit the bending or delamination of PCB at high temperatures, ensuring that the substrate of LED and heat discipline in close contact, avoiding the accumulation of heat caused by poor contact.
