PCB Manufacturing Engineering Technology

Long-Term Reliability of High-Frequency Circuit Materials and Printed Circuit Boards

As complexity and density increase, the long-term reliability of RF/microwave circuit components becomes more challenging to characterize. Printed Circuit Boards (PCBs) comprise numerous active and passive components, whose performance can vary over time and with operating environment temperatures. Additionally, PCB substrate materials, such as dielectrics, copper foil conductors, solder mask inks, and final finishes, may change over time, influenced by environmental conditions. Higher frequencies may experience changes in electrical performance over time, such as power and efficiency losses. These effects can occur in both short-term and long-term scenarios, often driven by thermal effects, particularly when operating in high-temperature environments.
