Quantum SCR is an Advanced Product Technologies company. APT started in 1982 as a manufacturer of Thin film Deposition systems and related equipment. These products were used in the manufacture of projects like the Maverick and Sidewinder missiles as well as the Space Shuttle and Hubble space telescope along with countless other projects. These projects required advanced technologies to meet the needs of a fast moving aerospace and defense industry. We met those needs by building exactly what our customers asked for at a price within their budgets.

In the 90s we also began to manufacture specialized computer peripherals for film and video as well as introducing automation and embedded processing into our line of products.

In 2000 we began to provide SCR control packages separately from our automation systems and created Quantum SCR to provide items needed in process heating control.
