We have developed a book programmable, inexpensive, spin coater to be used for applications in which flat substrates are lined with a homogeneous thin layer of a desired material. The apparatus is built with AC Servo motor. The automated program offers control, wide velocity range (from 0 to 8400В rpm), spin speed balance and compact size.

Spin covering has been utilized for several decades for the use of thin videos. A typical method involves adding a small puddle of a liquid resin on the center of any substrate after which spinning the substrate at high speed (typically around truck rpm). Centripetal acceleration may cause most of the plant to distributed to, and eventually off the border of the substrate, leaving a thin film of resin around the surface. Final film fullness and other real estate will depend on the nature of the plant (viscosity, drying rate, percent solids, area tension, and so forth ) and the parameters chosen for the spin procedure. Factors just like final revolving speed, acceleration, and blow up exhaust lead to how the homes of coated films will be defined.
