What is an Impedance Controlled PCB? An Impedance Controlled PCB is a printed circuit board designed and manufactured to maintain a specific characteristic impedance for signal traces, ensuring consistent signal transmission. In high-speed and RF designs, the PCB trace behaves like a transmission line. Without proper impedance control, signals can suffer from reflection, distortion, and...
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), typically above 170°C. The Tg value represents the temperature at which the PCB material transitions from a rigid state to a softer, more flexible state. A High Tg PCB maintains...
What is a High Layer Count PCB? A High Layer Count PCB refers to a multilayer printed circuit board with a large number of layers, typically 10 layers and above, and often reaching 20, 30, or even 50+ layers in advanced applications. A high layer count PCB is designed to handle complex routing, high-speed signals,...
What is a Buried Via PCB? A Buried Via PCB is a multilayer printed circuit board where vias are located between internal layers only, without extending to the outer layers. Unlike through-hole vias, a buried via PCB allows connections between inner layers while keeping the outer layers free for routing, enabling higher circuit density and...
Purchase RF PCB: What You Need to Know When you plan to purchase RF PCB, you are not just buying a standard circuit board—you are sourcing a high-frequency solution that directly affects signal performance, system stability, and product reliability. Unlike conventional PCB procurement, purchasing an RF PCB requires careful evaluation of: Material selection Manufacturing capability...
What is RO4003 PCB for 5G Antenna? An RO4003 PCB for 5G antenna is a high-frequency printed circuit board manufactured using RO4003 laminate, widely used in RF and microwave applications. RO4003 is a hydrocarbon ceramic material designed to provide low dielectric loss, stable electrical performance, and consistent impedance control, making it highly suitable for 5G...
What is a Probe Card PCB? A Probe Card PCB is a high-precision printed circuit board used as the core platform in probe cards for semiconductor wafer testing. It provides the electrical interface between the test system (ATE) and the wafer through probe needles or MEMS structures. Unlike standard PCBs, a Probe Card PCB must...
What is a 5G mmWave PCB? A 5G mmWave PCB is a high-frequency printed circuit board designed to operate in the millimeter wave (mmWave) frequency range, typically between 24 GHz and 100 GHz. At these frequencies, the PCB is no longer just a carrier—it becomes a critical part of the RF system, directly impacting signal...
What is an HDI PCB? An HDI PCB (High-Density Interconnect PCB) is an advanced printed circuit board designed with higher wiring density per unit area, using technologies such as microvias, fine lines, and sequential lamination. Compared to conventional PCBs, an HDI PCB enables more compact layouts, improved electrical performance, and higher signal density, making it...
What is an IoT IC Test PCB? An IoT IC Test PCB is a specialized test board designed for validating, debugging, and verifying integrated circuits used in IoT devices. Unlike standard PCBs, an IoT IC Test PCB is engineered for repeatable testing, accurate measurement, and long-term reliability. In IoT hardware development, the IoT IC Test...
