The Study of IR-reflow Condition Variations on the Warpage of PBGA Packages
The main objective of this paper is to utilizing the Shadow Moiré method to study the effect of IR-reflow Condition Variations on the warpage of PBGA Packages. Two combinations of different moisture and temperature status are also chosen for the purpose of the study.
The result shows that the first peak temperature is the most effective variable on the warpage of PBGA packages under the IR-reflow process.
