The foundation of PCT Systems relies on three distinct strengths: experience, innovation and cutting-edge technology.

These core values allow PCT Systems to excel in building megasonic and ultrasonic wet cleaning systems for semiconductor, medtech, renewables, optics, glass and additive manufacturing industries. This approach was established in 1988 by President and Founder Henry R. Miranda, a 30-year veteran in the semiconductor device fabrication and equipment industry. 

Today President Sharyl Maraviov offers a way to preserve the past, while simultaneously pushing toward modernization with her experience as a chemist, design engineer and MBA. She along with PCT’s dedicated employees are opening new doors and cultivating modern technology. 

PCT Systems is located in San Jose, California, in a 10,000 square foot facility. The products designed include Quartz and Plastic tank fabrication and electronics, as well as RF generator manufacturing. 


The mission statement of PCT Systems is clear — To provide technologically advanced, reliable megasonic systems and wet process equipment for the high-tech market and beyond. 

PCT offers standard and custom designed systems and components to end users and OEM manufacturers. Over the years, PCT has shipped thousands of process tanks and megasonic systems throughout the globe. Our products have been successfully used in semiconductor, solar, MEMs, Flat Panel Display, Hard Drive and numerous R&D settings in the world’s largest companies and most famous research institutions.
