What Is HDI PCB? HDI PCB (High Density Interconnect PCB) is a printed circuit board designed with higher wiring density per unit area compared to traditional multilayer PCBs. It uses advanced manufacturing technologies such as microvias, blind vias, buried vias, and fine line traces to achieve compact size and improved electrical performance. HDI PCB is...
What Is a Controlled Impedance PCB? A Controlled Impedance PCB is a printed circuit board engineered to maintain a precise and consistent impedance value along specific signal traces. Impedance control is critical in high speed and high frequency electronic systems where signal integrity directly affects performance and reliability. In modern electronic designs, signals travel at...
What Is a Rigid-Flex PCB? A Rigid-Flex PCB is a hybrid printed circuit board that integrates rigid PCB sections and flexible circuit layers into a single unified structure. Unlike traditional PCB assemblies that use connectors or cables between separate boards, a Rigid-Flex PCB eliminates mechanical interconnections by embedding flexible layers within the rigid stack-up. Rigid-Flex...
What Is a High TG PCB? A High TG PCB is a printed circuit board fabricated using high glass transition temperature (TG) laminate materials, typically with TG values above 170°C, 180°C, or even 200°C depending on application requirements. The glass transition temperature (TG) refers to the temperature at which the PCB substrate transitions from a...
What Is a Blind Via PCB? A Blind Via PCB is a type of printed circuit board that contains vias connecting internal layers to one or more outer layers without passing completely through the board. Unlike through-hole vias, blind vias help: Reduce board size Increase routing density Optimize multilayer stack-ups Support HDI (High Density Interconnect)...
What Is a High Current PCB? A High Current PCB is a printed circuit board specifically designed to carry large currents while maintaining electrical stability and thermal reliability. These PCBs are commonly used in power electronics, automotive inverters, industrial automation, renewable energy systems, and high-current semiconductor testing. High current PCBs typically feature thick copper layers,...
What Is a Microvia PCB? A Microvia PCB is a printed circuit board that uses microvias, which are very small drilled holes (typically <150 μm) to interconnect layers in high-density, multilayer HDI PCBs. Microvias enable fine-pitch routing, high pin count IC integration, and compact board layouts, making them essential for advanced electronics such as smartphones,...
What Is a High Reliability PCB? A High Reliability PCB is a printed circuit board designed and manufactured to perform consistently under extreme environmental, electrical, and mechanical conditions. These PCBs are engineered for long service life, stable electrical performance, and minimal failure risk. High reliability PCBs are essential for applications where system failure is not...
A multilayer rigid-flex PCB manufacturer specializes in producing printed circuit boards that combine rigid PCB sections with flexible circuits into a single integrated structure. Multilayer rigid-flex PCBs offer superior electrical reliability, space savings, and mechanical durability, making them ideal for advanced electronic applications where performance and compact design are critical. As modern electronics move toward...
What Is a High TG PCB? A High TG PCB is a printed circuit board manufactured using materials with a high glass transition temperature (Tg). The Tg value indicates the temperature at which the PCB substrate transitions from a rigid state to a softer, rubber-like state. Compared to standard FR-4, High Tg PCBs maintain mechanical...
