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 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 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 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 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...
What is Taconic PCB? Taconic PCB refers to printed circuit boards manufactured using high-performance laminates from Taconic, a well-known material supplier specializing in RF and microwave substrates.
