Abstract
Thermal radiation characteristics of materials associated with their interactions in the electromagnetic (EM) curing process of head gimbal assembly (HGA) are studied to identify process factors involving a random soft electrostatic discharge (ESD) of a read sensor that is located on a slider. The oven temperature measurement with K-type grounded thermocouples that are also used regularly as real-time and non-contact slider temperature measuring tools, show relatively higher temperature in the center of the carrier than its both ends. It is then shown from the two-dimensional (2D) model that the center slider temperatures are apparently different when different types of thermocouples are used. The center slider's peak temperature increases steadily with a decrease in the suspension's thickness and width, and, in some cases, is higher than ones measured by the thermocouple. ฉ 2011 IEEE.
