Automatic Calibration Equation for Microcontroller Based Dip Coater Tools with Point Capture Calibration System

Abstract

Microstructure technology is developing very quickly. Nanomaterials are very important, especially in manufacturing thin films made from organic, inorganic, metallic, and non-metallic materials, which can have the properties of conductors, semiconductors, superconductors, or insulators. Much research has been carried out regarding the process of making thin films. Dip-coating involves immersing the material in a solution for a specific time and then removing the material from the container. In the dip-coating technique, several parameters are essential to control. These parameters include immersion speed, soaking time, and material withdrawal speed from the coating material. Withdrawal speed is an essential variable in this technique because it affects the thickness of the layer formed. Giving different speeds will produce different layer thicknesses. This research will formulate a dip coater calibration system that can digitally regulate the immersion and withdrawal speed to program a microcontroller-based dip coater according to user needs. The method used is Research and Development. The problems that have been presented can be solved using mathematical equations that are often applied in real life. Applying equations in the stepper motor calibration process is a solution to obtain precision and accuracy tools. Through a simple mathematical approach, a dip coater tool calibration equation can be formulated with a point capture calibration system, which can increase the precision and accuracy of the tool and minimize more accurate errors.
