Resin pellet age determination with treatment and exposure to deformation force for semiconductor production

摘要

The method includes the first step of preheating treatment of the resin pellet (14), then exposing the treated pellet to a deformation force for a predetermined time duration. The deformation is then measured after the expiry of the predetermined time. The measured deformation of the pellet is compared with a predetermined expected deformation, determined as a function of the age of the resin in such a manner that the age of the pellet is determined.
