Abstract
An LGA connector is used to interconnect an LGA package and a printed circuit board. The LGA connector includes an elastomeric body with a plurality of through-holes. Metal films are formed on inner walls of through-holes and splay out around the mouths of their upper and lower openings. The metal films are formed by vacuum metallization, sputtering, chemical plating, electrical plating or PVD. The through-holes have a funnel-like shape to absorb external stresses and redirect the stress to shrink the through-hole diameters. Moreover, the metal films' elastic deformation is larger than conventional metal conductive fillers so as to improve reliability.
