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...
What is a Low Loss PCB? A Low Loss PCB is a printed circuit board designed using materials and structures that minimize signal attenuation (loss) during transmission, especially in high-frequency and high-speed applications. As data rates and frequencies increase, signal loss becomes a critical issue. Standard PCB materials like FR4 introduce higher dielectric loss, making...
What is a Fine Line PCB? A Fine Line PCB refers to a printed circuit board with extremely narrow trace width and spacing, typically below 100 μm (4 mil) and often reaching 50 μm (2 mil) or less in advanced designs. These PCBs are essential for high-density interconnect (HDI) and miniaturized electronic products, where space...
What is an RF Trace PCB? An RF Trace PCB refers to a printed circuit board specifically designed with controlled impedance traces to handle radio frequency (RF) signals. Unlike standard PCB routing, RF traces must maintain consistent electrical characteristics to avoid signal loss, reflection, and distortion. In RF design, the trace itself becomes part of...
What is a PTFE PCB? A PTFE PCB is a printed circuit board manufactured using Polytetrafluoroethylene (PTFE)-based materials, commonly known as Teflon. It is specifically designed for high-frequency and high-speed applications, where signal integrity and low loss are critical. Compared to standard FR4, PTFE PCBs offer extremely low dielectric loss, stable electrical performance, and excellent...
What is a Ceramic PCB? A Ceramic PCB is a type of printed circuit board that uses ceramic materials as the substrate instead of traditional FR4. These materials provide exceptional thermal conductivity, electrical insulation, and mechanical stability, making them ideal for high-power and high-temperature applications. Unlike standard PCBs, ceramic boards can efficiently dissipate heat directly...
What is BT Epoxy PCB? BT Epoxy PCB refers to printed circuit boards manufactured using Bismaleimide-Triazine (BT) resin, a high-performance material widely used in semiconductor packaging and advanced electronic applications. Compared to standard FR4, BT epoxy offers superior thermal stability, lower moisture absorption, and improved electrical performance, making it ideal for IC substrates and high-reliability...
