Sono-Tek Corp (SOTK)

A. Company Overview

Sono-Tek Corporation is recognized as a leading entity in the field of ultrasonic coating technology, engaged in designing and manufacturing systems for the precise application of thin film coatings. These coatings serve various functional purposes such as protection, enhancement, and strengthening of surfaces for a diverse range of industries, including microelectronics, alternative energy, medical, industrial applications, and emerging research initiatives. The company's foundation rests on patented technology combined with robust application engineering expertise, enabling it to deliver custom-engineered coating solutions tailored to customer specifications.

The ultrasonic nozzle technology developed by Sono-Tek transforms liquids into minute droplets through high-frequency ultrasonic vibrations. This atomization allows for the application of microscopic layers of various materials onto surfaces, including metals and glass, at low velocities. The solutions provided by Sono-Tek are noted for their environmental friendliness, efficiency, reliability, and ability to significantly reduce overspray and raw material consumption, thereby improving overall process repeatability and minimizing emissions.

Initially, Sono-Tek's technology was employed for coating the inner surfaces of blood collection tubes utilized in medical diagnostics, effectively preventing blood coagulation. The application spectrum expanded to include uniform flux coatings for printed circuit boards, an essential step in the production of electronic devices. The company has also addressed challenges in the glass manufacturing sector, providing coatings that enhance durability, optical clarity, electrical conductivity, and safety features, particularly relevant in construction and automotive applications.

Founded by Dr. Harvey Berger, the inventor of the ultrasonic nozzle, Sono-Tek was incorporated in New York on March 21, 1975, and became publicly traded in 1987. Its corporate headquarters and production facilities are situated in Milton, New York, in addition to having a sales and service office in Singapore and a process development laboratory in Guangzhou, China. The company is ISO 9001 certified, a recognition it has maintained since 1998 through annual recertification.
