Produttore di PCB in alluminio

PCB in alluminio è un laminato rivestito in rame a base metallica con una buona funzione di dissipazione del calore. In generale, la struttura del rivestimento ha tre strati, che è lo strato del circuito (foglio di rame), lo strato dielettrico e lo strato di base metallico (base di alluminio). Ci sono due lati, il lato anteriore e quello posteriore. I pin LED richiedono una saldatura superficiale bianca e l'altro lato è in forma di alluminio.

Generally, the thermal conductive paste is applied and is contacted to the heat conductive portion. Also used for high-end use is designed as a double layer, the structure is circuit layer, a dielectric layer, aluminum base, dielectric layer, circuit layer. A very small number of applications are multi-layer boards, which can be made of ordinary multi-layer boards combined with a dielectric layer and an aluminum base.

Aluminum PCB Advantages:

Il aluminum PCB is a low-alloyed Al-Mg-Si high-plasticity alloy board, which has good thermal conductivity, electrical insulation properties, and machinability. Comparing with FR4, the aluminum substrate can carry higher current when has the same thickness, the line width, and it withstands voltage up to 4500V, the thermal conductivity is greater than 2.0.

• Minimize thermal resistance and has an excellent thermal conductivity.
• Meet RoHS requirements.
• More suitable for SMT process.
• Extremely effective treatment of thermal diffusion in the circuit design scheme, reducing module operating temperature, extending service life, improving power density and reliability.
• Reduce assembly of heat sinks and other hardware (including thermal interface materials), reduce product size, reduce hardware and assembly costs; optimize the combination of power circuits and control circuits.
• Replace the fragile ceramic substrate for better mechanical durability.

Application:

• Audio device: Input, output amplifier, audio amplifier, balanced amplifier, power amplifier, pre-amplifier, etc.
• Power Supply: Switching regulator, DC / AC converter, SW regulator, etc.
• Filtering appliances, transmitter circuit, etc.
• Office automation equipment: Motor drive, etc.
• Automobile: Electronic regulator, ignition, power supply controller, etc.
• Power Modules: Inverter, solid-state relays, rectifier bridges, etc.
• Lamps and lighting: As the advocated promotion of energy-saving lamps. At present, there is a large variety of color-saving LED lamps in the market. PCB in alluminio used in LED lights also begins large-scale applications.
