Abstract:
A structure of a Ball Grid Array IC socket connection with solder balls comprising:a socket having a plurality of wall blocks defining a plurality of through slots; a plurality of conductive plates, each conductive plate is fitted into one of said through slots; each of said plurality of conductive plates have an upper end for insertion and clipping with IC pins and a lower end formed into a branching opening for elastically clipping of a solder ball; said upper end of each of said plurality of conductive plates extends in a direction from a side of said plurality of conductive plates; said branching opening is located at a height higher than one-half of a height of said solder ball; an arc-shaped blocking plate is formed on each of said conductive plates and extends in a direction from a front face of each of said conductive plates; said direction of said upper end is transverse to said direction of said arc-shaped blocking plate; two parallel legs are formed on said lower end of said plate bodies; said wall blocks have projections that extend into said slot to substantially center said solder ball with respect to said arc-shaped blocking plate; said arc-shaped blocking plate is substantially bent about a center, said arc-shaped blocking plate has a radius first position that extends from said center to a distal end of said arc-shaped blocking plate, and a radius second position that extends from said center to said conductive plate; an angle of substantially 180 degrees is between said radius first position and said radius second position; whereby an upper portion of said solder ball is held by said arc-shaped blocking plate, said legs, and corresponding wall of a respective one of said through slots without soldering.
