This study investigates the effect of focal plane variation using vibration in a femtosecond laser hole drilling process on Invar alloy fabrication quality for the production of fine metal masks (FMMs). FMMs are used in the red, green, blue (RGB) evaporation process in Active Matrix Organic Light-Emitting Diode (AMOLED) manufacturing. The taper angle of the hole is adjusted by attaching the obj...

Purpose. Analysis of the theoretical foundations, design schemes and methods for calculating technical technological support drilling cycle operations using dynamic shock impulses in order to intensify destructive processes at bottom a well under construction. Research methodology. Laboratory studies features functioning devices generating pulses were carried out modern experimental research, p...

In the prospecting and drilling processes of gas and oil, if added into the drilling fluids, the latex nanoparticles can improve the performance of the drilling fluids. In this paper, methyl methacrylate (MMA) acts as a monomer and the combination emulsifier is a certain proportion of OP-10, RH and T-80. PMMA latex nanoparticles have been polymerized through the method called microemulsion poly...
