SAMTEC has expanded its 1mm pitch micro card socket line (MEC1 Series) with the addition of right angle and edgemount designs to its original vertical surface mount design.
These sockets have a double row of beryllium copper contacts on 1mm pitch to provide the ultimate solution for many micro card interfaces.
They mate with 1.6mm cards or with Samtec's standard flex cable data links (MEJ1 Series) designed to mate with these mini edge card sockets.
Eight standard sizes are available with a choice of 5, 8, 20, 30, 39, 49, 58 and 68 I/Os per side. The largest vertical design has a total of 136 I/Os in less than 645mm2 of PCB area while the right angle design requires approximately 1.35 square inches 870mm2. The edgemount design requires less than 330mm2 on each side of the board.
Sockets are normally polarised to provide error free mating; however, smaller sizes with up to 30 contacts per side may be specified with or without polarisation to maximise I/O density.
Polarisation in these smaller sizes requires the loss of one I/O per side.
