Insulation layer is the core technology of aluminum PCB

<p><strong>Aluminum <a href="https://www.atechpcb.com/aluminum-pcb-metal-core-pcb" target="_blank">PCB</a></strong> structure is mainly divided into three layers: circuit layer, insulation layer and metal layer. After etching the circuit layer, a printed circuit is formed for arrangement and connection.</p><p><br></p><p>Compared with the traditional FR4 PCB, if both use the same thickness and the same line width, the<a href="https://www.atechpcb.com/<a href="https://www.atechpcb.com/aluminum-pcb-metal-core-pcb" target="_blank">aluminum</a>-pcb-metal-core-pcb" rel="noopener noreferrer" target="_blank"> <a href="https://www.atechpcb.com/aluminum-pcb-metal-core-pcb" target="_blank">aluminum PCB</a></a> can carry higher current. The function of the insulating layer on the aluminum PCB is adhesion, insulation and thermal conductivity, which is the core technology on the metal core PCB.</p><p><br></p><p>The <a href="https://www.atechpcb.com/aluminum-pcb-metal-core-pcb" rel="noopener noreferrer" target="_blank">aluminum PCB</a> insulation layer is the largest heat conduction in the power structure. The better the thermal conductivity of the insulation layer, the more it helps to diffuse the heat generated during operation, so it is better to reduce the operating temperature of the device, thereby increasing the power load of the module, reducing the volume, extending the service life, and increasing the power output.</p>
