Täppistehnika

Täppistehnika, literally “precision technology” in Finnish, is a field of engineering and applied science that concentrates on achieving high accuracy, repeatability, and reliability in measurement, manufacturing, and automated control. It combines metrology, precision engineering, instrumentation, and precision automation and is applied across manufacturing, research, and technology development.

Core concepts include traceability to national or international standards, measurement uncertainty, calibration, and error modeling. Practitioners use high-precision instruments such as coordinate measuring machines, laser interferometers, optical encoders, and precision actuators, together with advanced control systems and statistical methods to minimize both systematic and random errors along the production and inspection chain.

Historically, täppistehnika grew with advances in microfabrication, computer numerical control, laser metrology, and sensor technology. It aligns with international standards in metrology and quality management to ensure consistent measurements and quality across organizations and borders.

Applications include semiconductor fabrication, automotive and aerospace components, medical devices, pharmaceuticals, and scientific instrumentation. In education and research, programs in engineering and metrology train professionals to design, calibrate, and certify high-precision systems.
