SPI Chem™ Wet Surface Replica Kit

Instructions for Use: Inspection of negative replicas

Inspection is done using a stereo zoom light microscope with optics up to 70X. While even the best of "masters" making replicas do on occasionally end up with a small area containing a few "bubbles", one should find areas that are devoid of such artifacts on all replicas of a series so that when the SEM work is actually done, an area can be selected which contains no artifacts in any replica in the series. If such an area can not be found, then we would recommend going back and making a new set of negative replicas rather than putting good time after bad and trying to resurrect good results from a basically bad results situation.
