Compared with FR4, the aluminum   PCB  can minimize the thermal resistance, so that the aluminum  PCB   has excellent thermal conductivity.   aluminum pcbs can be divided into 5 categories: single layer aluminum PCB, multilayer aluminum pcb, mixed aluminum pcb, through hole aluminum pcb, and flexible aluminum pcb.       1.  Single Layer Aluminum PCB Singl e layer   aluminum pcb  is the most common one. Compared with other types of  aluminum pcb , its  technology  process is simple, and its applications are particularly wide. It is often used in LED lighting products.  Generally, a single layer pcb is composed of a 3 layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer.     2.  Multilayer Aluminum PCB In the high-performance power supply market, multilayer  aluminum pcb   are made of multilayer thermally conductive dielectrics.   These structures have one or more layers of circuits buried in the dielectric, and blind vias are used as therma

C eramic PCB   is made by bonding the copper foil and the ceramic substrate together in a high temperature environment.   Its bonding force is strong, the copper foil will not fall off, and the reliability is high. Its performance is stable under the environment of high temperature and high humidity, so it is widely used in three fields.       1. Automotive electronics industry Ceramic PCB is very important in improving the overall quality of automotive sensors.  The material of the sensor chip is generally silicon, and the thermal expansion coefficient of ceramics and the chip are close, and will not cause too much deformation when the temperature difference changes drastically to cause the circuit to be unsoldered. When a car is running, the internal parts of the car body are in a very harsh environment, and they are often exposed to high temperature and strong corrosion. Ceramic PCB uses inorganic non-conductive ceramic as the  base material , and the metal is in direct contact with

Ceramic PCBs are better than ordinary PCBs due to their heat dissipation performance, current - carrying capacity, insu lativity , coefficient   of thermal expansion , etc. so they are widely used in various fields. So what are the application areas of ceramic PCBs?       1.  High-power power electronic module High-power semiconductor modules are a combination of certain functions and modes.  Whether it is an insulated gate bipolar transistor (IGBT) or a DC high-power module, ceramic PCB is one of the main core components and has a very large heat dissipation requirement.  No matte r how  heat  is  generated, the first contact point of the heat is the substrate, so aluminum nitride ceramic PCB is undoubtedly the best choice.     2.  Solar panel components Ceramic PCB uses ceramic  chip  as substrate  and does  no t  requir e an  insulation layer . The heat on the copper circuit is directly conducted to the ceramic chip, which can better dissipate heat. It has good electrical conductivi
