JAE Europe has introduced a 140-way board-to-board PCI Express connector, enabling embedded systems, copiers, medical equipment and other applications to benefit from multi-Gigabit, multi-channel serial communications. The WB4 series comprises right-angle connectors enabling horizontal mating of adjacent boards. The 0.5mm conductor pitch ensures a low footprint to enable multi-channel interconnects within minimal board real-estate. The connectors are designed to close tolerances throughout, which results in precision matching between differential signal pairs as well as high signal integrity. Insertion loss is reduced to -5dB at 3.75GHz due to contact resistance below 100mΩ. Return loss is better than -4dB and cross-talk performance better than -26dB at 3.75Ghz. Insulation resistance greater than 100MΩ ensures compliance with all applicable user-protection standards, and the connectors also exceed 200Vrms per minute dielectric withstand voltage. The WB4 series connectors are also optimised for surface-mount assembly, with high coplanarity of electrical contacts and features to aid picking and alignment with automated placement equipment. Available connectors are specified over the extended temperature range from -40 to +85°C, to support designers seeking to use PCI Express in Industrial, Scientific and Medical (ISM) applications.
