What Is a Heavy Copper PCB？ A Heavy Copper PCB is a printed circuit board manufactured with thick copper layers, typically 3 oz/ft² and above. In some high-power applications, copper thickness can reach 10 oz, 20 oz, or even more depending on current requirements. Unlike standard 1 oz copper PCBs, heavy copper boards are designed...
What Is a SiC PCB? A SiC PCB is a printed circuit board specifically designed to support Silicon Carbide (SiC) power devices. SiC semiconductors operate at higher voltages, higher temperatures, and higher switching frequencies compared to traditional silicon devices. Because of these characteristics, the PCB supporting SiC components must provide superior thermal management, electrical insulation,...
A High TG PCB refers to a printed circuit board manufactured with laminate materials that feature a high glass transition temperature, typically 170°C or above. However, in advanced electronics, High TG material selection is not only about temperature tolerance — it is fundamentally about mechanical stability under thermal stress. In multilayer, thick copper, and high-power...
What Is a Multilayer PCB? A Multilayer PCB is a printed circuit board consisting of three or more conductive copper layers laminated together with insulating dielectric materials. These layers are electrically interconnected through plated vias to create complex routing structures within a compact footprint. Compared to single-layer or double-layer boards, multilayer PCBs enable higher circuit...
Engineering Challenges Behind High Density PCB As electronic systems become more compact and functionally integrated, PCB designers are facing increasing layout complexity. A High Density PCB is not simply about placing more components on a board — it requires precise coordination between electrical design, stack-up engineering, manufacturability, and long-term reliability. High density PCB development focuses...
What Is an HDI PCB? An HDI PCB (High Density Interconnect PCB) is a printed circuit board designed with higher wiring density per unit area compared to traditional PCBs. It typically incorporates microvias, blind and buried vias, fine trace widths, and advanced multilayer stack-ups to support compact and high-performance electronic designs. HDI technology enables smaller...
What Is a Rigid-Flex PCB? A Rigid-Flex PCB combines rigid circuit board sections with integrated flexible circuit layers into a single unified structure. This hybrid design allows the board to bend in specific areas while maintaining structural stability in others. Unlike traditional assemblies that connect separate rigid boards using cables or connectors, rigid-flex technology integrates...
What Is a High TG PCB? A High TG PCB refers to a printed circuit board manufactured using laminate materials with a high glass transition temperature (Tg). The glass transition temperature is the point at which the PCB substrate transitions from a rigid state to a softer, more flexible state under heat. Standard FR4 materials...
SiC PCB: Supporting the Next Generation of Power Electronics With the rapid growth of electric vehicles, renewable energy systems, and industrial power modules, Silicon Carbide (SiC) devices are becoming a key technology in modern power electronics. Compared to traditional silicon components, SiC devices operate at higher voltages, higher temperatures, and higher switching frequencies. However, these...
