Semicon mfgr. wants comparison of the various mold release coatings  

+++

Greetings!

I'm an engineer working on mold process in a semicon company. we experience some mold sticking of mold compound in mold chase. I just want to know the difference of these three different mold chase coatings: chrome, titanium nitride, and Cr-flon nano plating in terms of coefficient of friction, grainsize, wear resistance, adhesion/releasability from epoxy mold compound, hardness and roughness.

What I mean of difference between those properties are some data you've acquired like say coeffient of friction of chrome ____value, titanium nitride ___value, cr-flon__value, and other properties as well.

Thank you very much
