Quality Assurance
In line with our Quality Policy, Reliability & Quality Assurance Organization is structured to ensure that the established quality system is being implemented and maintained, as well as to ensure services provided and finished products built per customer’s requirements.
From incoming materials to final test, packaging and shipping, quality is assured along the manufacturing process through the usage of Quality Control Plan and Statistical Process Control monitoring. The control plan covers the prototype build, pre-production build and mass production to control all critical parameters and special characters of the products along the manufacturing process.
