*Daikichi Miyagawa¹, Katsunori Negishi¹, Ryo Okawa¹, Kazuyuki Uno¹ (1. University of Yamanashi)

Processing characteristics of polymer resin films using a short-pulse He-free CO₂ laser were investigated. Minimum total irradiation fluences required to form a through hole and minimum total irradiation fluences where undesired carbonization occurs were investigated.
