CTT is committed to the concept that quality must be designed in and not inspected into the product. The quality engineers review all designs for compliance to CTT’s quality and workmanship standards and assist design engineering in the selection of suppliers and components. Inspection points throughout the manufacturing process are maintained and deviations analyzed and controlled through TQM and SPC programs to ensure a consistent manufacturing process. To assure the highest level of reliability, CTT has implemented its own screening program derived from MIL-PRF-38534. Custom screening procedures are available on special request. CTT’s quality and process control systems are approved to AS9100 / ISO 9001 and JSTDs. Test and measurement equipment is calibrated in accordance with MIL-STD-45662 and ANZI-Z-540. CTT is an AS9100 / ISO 9001 Registered company and has received numerous supplier excellence awards for quality and performance.
