This invention is designing a tab on the tail of an ILS (Integrated Laminated Suspension) so that the bias force of the ILS tail is sufficient and adequate for beam solder attachment. The tab is formed on the stiffener plate of the ILS so that when it is aligned to the flex, the tab pushes against the comb arm, providing enough bias force. Without the tab, the lack of bias towards the flex cable will provide failures in the soldering process. This is especially benefitial in a long arm/short suspension design. As in the figure below, a small tab feature is designed on the ILS tail. This rests upon the comb arm when aligned to the flex cable. Since the ILS tail is thin and weak, without the tab, no bias force acts toward the flex cable. A tab close to the flex cable will create a bias force which will make the beam solder process possible. The position of the bias tab can be adjusted to tune the bias force. Support Tab £
