Spin coater based on brushless dc motor of hard disk drives
R. F. Bianchi, M. F. Panssiera, J. P. H. Lima, L. Yagura, A. M. Andrade, and R. M. Faria, “Spin coater based on brushless dc motor of hard disk drivers,” Progress in Organic Coatings, vol. 57, no. 1, pp. 33–36, Sep. 2006.
This paper presents development of a novel programmable, low cost, spin coater to be used for applications where flat substrates are coated with an uniform thin layer of a desirable material. The equipment is built with dc brushless motor present in most of the hard disk drivers (HDDs). The system offers manual control, wide speed range (from 0 to 10,000 rpm), spin speed stability and compact size. The paper also describes the use of such equipment for the fabrication of thin poly(o-methoxyaniline) (POMA) films, which are of particular interest for design organic electronic devices, such as diodes, transistor, sensors and displays.
Notes:
- Easy to use, safe and inexpensive
- Manual control, wide speed range and spin speed stability
- Implemented using Brushless motor
- Controlled by Arduino circuit
