9 z is from 0 3 to 0 8 in this preferred embodiment the thickness of the amorphous coating layer 21 is from 0 1 to 0 8 u03bcm preferably 0 2 to 0 5 u03bcm the amorphous coating layer 21 is not only coated upon the surfaces of the filling channel 10 and the mold cavities 11 and the channel 12 but also it can be deposited on all the upper surfaces 13 of the package mold 1 so as to protect the package mold 1 not to wear or corroded in the resin packaging process the amorphous coating layer 21 used on the package mold 1 has a dense amorphous structure so as to increase the ability of anti corrosion moreover the pollution on the channel 12 in the resin packing process generally carbides are accumulated thereon is reduced furthermore the hardness of the amorphous coating layer 21 is greater than 30 gpa which is far higher than the hardness of the prior art coating layer thereby when high viscosity and high hardness solidified resins are applied thereon the surfaces of the filling channel 10 and mold cavities 11 and the channel 12 are protected from wearing to have the effect of protecting the package mold 1 referring to fig5 the second embodiment of the present invention is illustrated those identical to the first embodiment will not described herein only those different are described to have preferred adhesion of the protection coating layer on the package mold 1 the protecting layer is formed as a graded layer the surfaces of the filling channel 10 and mold cavities 11 and the channel 12 are deposited with a graded layer by physical vapor.
