Following SMT and PTH assembly, all the boards undergo automated optical inspection in order to prevent and identify any assembly or soldering defects. This test is carried out using a state-of-the-art Omron RNS-pt.
Our inspection system guarantees the utmost reliability in all the boards assembled. Thanks to techniques for acquiring special images and processing them using a very special wide-spectrum lighting system, we obtain practically complete coverage of soldering joint and component positioning defects.
The operating principle is based on the acquisition of images detected by a high definition camera, combined with a ring lighting system which emits a flash sequence with different wavelengths. The images are then compared with those stored in the library, and if this comparison highlights any possible defects a specialist operator analyzes the signal, and if necessary remedies or flags up the problem. One hundred per cent of our production undergoes this test.
