Claim Text:
1. A method, comprising: characterizing a thermal interface material (TIM); quantifying a characterization of voiding of the TIM; determining process parameters to optimize adhesion and minimize voiding level of the TIM; validating a thermal performance of the TIM using the steps of characterizing, quantifying and determining; and when the validating does not meet thermal requirements of the TIM, then reverting to the determining step to adjust the process parameters, wherein the characterization of the TIM includes determining volatile content, temperature range for polymerization and cure, rheological behavior and viscosity range of the TIM, and wherein the process parameters include dispense method, dispense delay, pressure load applied during adhesive cure, and time and temperature range for preconditioning chemical prior to the cure.
