| Abstract: | Introduces the principle of the tin-ball laser bonding on hard disk sliders and its merit. By statistical analysis, the defects are tin-ball short, overflowing,dissymmetry,splash and scorch,which are mainly affected by the tin-ball size,pad positions, and process parameters .By finite element analysis, obtain the optimum of tin-ball diameter, the distance of the magnetic head pad to the suspension pad and the distance of the suspension pad to the magnetic head pad .The experiment shows that the simulation result is good and the acceptability is improved sharply. |
