Hi Ingemar, Got into this somewhat late. Your 'solution' may or may not work. Larger area will reduce shear stresses; if you have solder under lead, it is not a real solution. Solder will creep even at low stresses--so total displacement will occur if you have solder under lead. HOWEVER, if joint under lead is thin--that is mostly IMCs and Pb-rich phase--this reductiuon in stress level maybe sufficient to solve your problem. Thus, your solution would bve more successfull with LESS solder rather than MORE solder. Regards, Werner Engelmaier Engelmaier Associates, L.C.
