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.
RT-duroid® laminates are high-performance PTFE-based composite materials manufactured by Rogers Corporation. These laminates are primarily used in RF, microwave, and high-frequency applications due to their exceptional dielectric properties, thermal stability, and chemical resistance.
RT/duroid® 5870 and 5880 glass microfiber reinforced PTFE
composites are designed for exacting stripline and microstrip
circuit applications.
RT-duroid 5870 laminates are high-performance microwave and radio frequency (RF) circuit materials manufactured by Rogers Corporation. These laminates are widely used in high-frequency applications due to their low dielectric constant, low loss tangent, and excellent stability under various environmental conditions.
