Striplines are transmission lines embedded within a dielectric medium and are widely used in high-frequency circuits for their excellent signal integrity and predictable impedance. Broadside and edgewise striplines are two common configurations, differing in how the signal and ground planes are arranged. Understanding the design equations is crucial for impedance control and circuit optimization.
RT-duroid® laminates are widely used for high-frequency applications, offering excellent dielectric properties and dimensional stability. However, after the etching process used to define circuit patterns, internal stresses can develop in the laminate, potentially affecting its performance and reliability.
RT-duroid® 5870 laminates, consisting of a PTFE-based substrate reinforced with glass microfiber and bonded to copper foil, are widely used in high-frequency applications. The adhesion between the copper foil and the PTFE substrate is a critical factor for the reliability and performance of these laminates, particularly during soldering processes.
RT-duroid® laminates, based on polytetrafluoroethylene (PTFE) reinforced with glass microfibers or ceramics, are commonly used in high-frequency applications. When exposed to nuclear radiation, these materials exhibit specific changes in physical, electrical, and mechanical properties.
The nearly isotropic dielectric constant (ϵr\epsilon_rϵr) of RT-duroid® 5870 – 5880 laminates, attributed to their glass microfiber-reinforced PTFE composition, offers several key benefits for high-frequency applications.
hen Rogers high-frequency circuit boards, such as RT-duroid laminates, carry direct current (DC) or radio frequency (RF) current, the temperature rise depends on factors such as conductor resistance, material properties, current flow, and thermal management.
Polytetrafluoroethylene (PTFE)-based composites, such as RT-duroid laminates, are widely used due to their exceptional properties. However, working with PTFE composite materials requires awareness of safety precautions during handling, machining, and disposal.
In modern electronic devices, the performance of control boards directly impacts the reliability and accuracy of the entire system. Whether in industrial automation, medical devices, or consumer electronics, data acquisition and signal processing boards (DAQ and Signal Processing PCBs) play a crucial role. To ensure that the system can efficiently and accurately process signals from sensors and other electronic components, optimizing PCB design is essential.
