Top Testing Technology
Production and quality measurement technologies at Bosch are designed to maintain the demanding quality standards of our hightechnology products. Dimensional measurement technology continues to gain in importance for inspections dealing with increasingly smaller tolerances — often in the range below one micrometer. No material defects must be allowed to escape detection during the manufacturing process. In largescale production, this often requires 100% inspection with high precision and very short cycle times.

The most widely used techniques at Bosch include optical interferometry, eddy-current and ultrasound methods, as well as radiography and X-ray computer tomography. Bosch researchers’ ideas for metrology and test systems also inspire innovations in peripheral areas, such as an X-ray system for checking the weight of pharmaceutical capsules in packaging machines. In the future, the farsighted planning of inspection strategies will become increasingly important in supporting advanced product development in research.
