  • Finite element method was used to simulate the soldered joint of J-lead of the SOJ (Small Outline J-lead Package). Results indicate that the distortion is obvious, the ceramic carrier with up-warp trend, the J-lead with forth extension trend, but the PCB with little distortion because of the rigidity displacement restrict. The strain of the J-lead soldered joint' soldered heel is bigger than the soldered toe and the center place has the least strain. The stress of the J-lead soldered heel is… CONTINUE READING
