The present invention accommodates, in an integrated suspension assembly for a magnetic disk storage system, tolerances in the lead and slider position in a manner to maintain gimbal integrity, minimize static attitude variation and reduce stress build up in the lead. In one aspect of the present invention, the nominal lead position and slider position are chosen such that the distance between them in an overlapping interference manner is no more than (a+b), the sum of the extreme tolerance a of the lead position and extreme tolerance b of the slider position. This is to ensure at least line to line contact between the slider and the leads, in an interference type contact configuration. In another aspect of the present invention, the ends of the leads are coated with a layer of solder material which can be reflowed to form a solder joint bonding the contacting leads to the slider. In another aspect of the present invention, a yield interference design is implemented wherein the leads are pre-bent to an extent and positioned such that the lead material goes beyond yield point during subsequent interference lead termination. This would minimize variation of slider static attitude from one part to another after slider to lead termination. Further, the leads may be pre-bent with a slight S-shaped section for accommodating such further bending. Similarly for a clearance type contact configuration, the leads are positioned to go beyond the material yield point during assembly. In yet a further aspect of the present invention, a solder ball may be inserted between the slider and a lead so that when the solder ball is reflowed, the clearance between the slider and the lead is taken up for minimum stress increase in the leads and minimum slider attitude change during assembly.
