Low-cost high-density PCB stacking connectors ensure interface consistency

RS Components has introduced the Amphenol ICC BergStak Lite 0.8mm vertical mating PCB-to-PCB connector system. An economical yet versatile connector range with a multiplicity of configuration options, The system is especially well suited to high-density, high-speed parallel board stacking applications in IP phones, measurement equipment, portable industrial terminals, POS terminals, security systems and test equipment. The system comprises straight PCB headers and sockets with a choice of 40, 60, 80 or 100 contact positions arranged at 0.8mm pitch in one to four rows. A selection of 16 PCB stacking heights is offered, in 1mm increments from 5mm to 20mm. Design engineers are therefore presented with a consistent mating interface across a wide variety of formats to support evolving designs and mechanical requirements. Depending on stack height, the system can support data rates of up to 12Gbit/s — compatible with PCIe version 3 and SAS 3.0 high-speed bus performance. The 0.8mm contact pitch preserves PCB space for high-density applications. Inexpensive gold flash plating on the contact areas maintains 50 mating cycles, while a scoop-proof housing stops terminal damage due to reverse mating. Optional PCB locator pegs support easy, accurate manual assembly. The system has an operating temperature range from –40C to +125C and is available in a UL94 V-0 rated flame retardant LCP (liquid crystal polymer) material. It is RoHS compliant and lead-free.
