Lapping is the precise and controlled removal of material to analyze a structure layer by layer sequentially. A series of fine abrasives or lapping films are used to carefully delay the sample, creating a flat and polished surface for examination. This technique can be used to analyze PCBA thermal events or delayer semiconductor die from passivation to poly.
