The package mould possesses at least one flute to accommodate at least one package base plate. The package base plate possesses outer sidewall with first height, and the flute possesses inner sidewall with second height. The outer wall is connected to the inner wall electrically, and the second height is larger than the first height in order to prolong the contact period between the outer wall and the inner wall when the base plate leaves package mould. Thus, static electricity produced in process of leaving the package mould will be discharged through the assembly. The invention reduces damages caused by electrostatic so as to increase package proporty.
