Abstract:
An electrical connector system comprising:a PCB forming signal pads and ground pads both on an upper face and a lower face; andan electrical connector mounting to an edge of the PCB, comprising:a die-cast metal housing defining at least a cavity therethrough and forming a pair of boardlocks rearwardly projecting from opposite sides of a rear surface thereof, each boardlock including a base and a triangular supporting plate substantially perpendicular to the base;a terminal insert being accommodated in the cavity,wherein said terminal insert comprises a plurality of signal contacts being respectively received in a first and a second terminal cores and being suitable for electrically connecting with the signal pads on the PCB, each signal contact including a contact tail extending from an end thereof to be straddle mounted to the PCB; anda ground plate being sandwiched between said first and second terminal cores and including a plurality of ground tails coplanar with the contact tails and extending out of the housing to be straddle mounted to the PCB and to engage with the ground pads; wherein before the connector and the PCB are assembled together in a front-to-back direction, a solder paste is applied to each of said signal and ground pads and deformed to be a corresponding solder ball via a reflowing procedure.
