Design and implementation of a low-cost spin coater for thin film deposition
(UMT, Lahore, 2024) SAHA ZAINAB; SYEDA SAMREEN ZAIDI
The design and development of the economical and efficient spin coater is described in this paper. A spin coater deposits a film uniformly on the target material and can be made using information of various disciplines such as Electronics, Mechanics and Physics. The system is developed using a brushless motor along with an Arduino and ESC for accurate speed regulation making it simple and cost effective. An Arduino is used as a microcontroller to coordinate the coating process and communicate with the LED display and ESC. The spin coater has a speed range from 500rpm to 1500rpm, making it easy to develop different film thicknesses, which can be controlled depending on the material used. This spin coater, developed with easily accessible mechanical and electronic components, offers a user-friendly approach for achieving uniform thin films, making it appropriate for widespread use in academic and research settings
