Abstract

In Magnetic Head Operation (MHO) industry, the magnetic head (so-celled slider) is the very important part. There is a need to continuously improve the product. One approach to enhance the slider efficiency is to increase the number of sensor (bond pads). The increase in the Bond Pad is Require a new bonding process by trial to use laser bonding. The research methodology was applied Finite Element Method to setup model for finding the optimal parameters in Back Side Pads bonding. There are 3 parameter to concern; they are Laser Energy, Time during bonding process and Foece during welding. The response of the Experiments are Minimize the arched of Slider (Crown Camble Twist) The result show that the optimal solution are 41mJ of laser power, bonding time for 2 seconds and 1 Newton force cause the Crown = -3.098 Camble = -2.022 and Twist = -0.281, which is recognized in the industry.
