Abstract

Because of their high viscosity, spin on glue materials used for permanent and temporary bonding applications are usually difficult to dispense and filter at the point of use and achieve high quality, uniform, bubble-free coatings. In this paper, we will focus on the use of the IntelliGen® HV dispense system and its optimisation to improve the temporary bonding material coating uniformity. The system was first utilized without filtration to understand the effect of bubble introduction to the coating. The second phase of the project studied the impact of filtration on the quality of the coating when bubbles were introduced. Coating uniformity data were collected by a Senduro reflectometer and bubble defectivity studies were performed using the NandaTech® SPARK inspection tool.
