In millimeter wave designs, compression mount connectors can be used to avoid problems commonly associated with solder variations. However, when using compression mount connectors, the potential impact of pin compression and/or misalignment on electrical performance at high frequencies should be considered. Using modeled and measured data, this white paper investigates how misalignment and pin compression could impact a real-world design. It also explains how to detect and avoid issues in order to optimize performance and complete a successful design.
