          DPC(Direct Plating Copper) technology and DBC(Direct Bond Copper) technology are two commonly used ceramic substrate manufacturing technologies.  While they are both method for manufacturing ceramic substrate, there are some important differences between them that make the DPC  technology   more expensive than the DBC technology.   1.  Definition DPC  Technology : It refers to a technology of plating copper directly on the ceramic surface. It can be achieved by electroplating or  hot plating . DBC  Technology:   It refers to a technology that directly combines  copper and ceramics. It is usually made by adding oxygen element between copper and ceramics , followed by  chemical metallurgical bonding.     2.   Advantages DPC Technology: 1)  The temperature  of  magnetron sputtering  technology  is below 300°C, completely avoiding the adverse effects of...

          In the field of lighting, high-power LEDs have become the preferred choice for many lighting projects due to their exceptional brightness and wide range of applications . As the core component of high-power LEDs, the high-power LED PCB plays a crucial role. It offers a series of significant advantages, providing a solid foundation for the efficient and stable operation of high-power LEDs.   1.  Excellent Heat Dissipation High-power LEDs generate substantial heat during operation. If not dissipated effectively, this heat can severely impact the lifespan and performance of the fixture. High-power LED PCBs are designed with specialized materials and structures to greatly improve thermal management.     The substrate typically employs metal   base   materials (such as aluminum or copper), which have excellent thermal conductivity, allowing rapid heat transfer away from the  fixture s. For example, aluminum   bas...

          With the continuous advancement of artificial intelligence (AI) technology, aerospace systems are rapidly evolving toward greater intelligence.  As the core of artificial intelligence hardware, a rtificial intelligence PCBs (AI PCBs) are playing an increasingly critical role in the aerospace field. They not only support high-speed computing and intelligent algorithms but also operate stably in complex and extreme environments, providing robust support for critical tasks such as flight control, fault diagnosis, and target recognition. 1. Flight Control and Intelligent Navigation In various types of aircraft, AI PCBs integrate GPUs, FPGAs, or dedicated AI chips to efficiently process data from multiple sensors such as GPS, inertial navigation systems, and radar. By applying artificial intelligence algorithms for path optimization and dynamic navigation adjustments, AI PCBs enable highly automated flight control. For example, in unmanned reconna...

          The basic material of PCB board is called base material, also called copper clad laminate. Components will generate heat when working, so the material of the PCB board must have the characteristics of heat resistant. Even if there is a fire, it must have the characteristics of being able to extinguish itself. So how to choose PCB copper clad laminate?   This degree of flame resistance is divided into grades, which can be divided into FR-1 to FR-5. The most commonly used one is grade FR-4 epoxy fiberglass cloth copper clad laminate, which is split into a "sandwich" structure, with copper foil on top and bottom and a prepreg in the middle.  Among them, prepreg is commonly known as adhesive pad. It is made by drying fiberglass cloth through a gluing machine to the "B" stage, that is, the prepreg is in a soluble and meltable state and will be used to directly press copper clad laminates.     Choosing copper clad laminates...
