Additional services
Quality
The CAQ software Babtec Q supports quality assurance across the entire process from initial sampling to outgoing goods inspection. Optical and tactile measuring systems such as a 3D coordinate measuring machine, 3D scanners (GOM, Creaform) and automated measuring projectors (Keyence) enable the measurement of complex components; in electronics production, 100% optical inspection is performed by AOI systems.
