Synchronization Trigger System Design of the Thermosonic Flip-chip Bonding

The stability and the delay time of the scan working model trigger system and the interrupt working model trigger system were compared and studied by the experiment of synchronization trigger of the thermosonic flip-chip bonding. It is found that the interrupt working model trigger system's stability was better than the scan working model trigger system's. It's biggest delay time, average delay time and the standard deviation of the delay time were all shorter than the scan working model trigger system's, especially the standard deviation just as small as 0.5mus. The result indicates that the delay time of the interrupt working model trigger system is 9mus less than a time cycle of the thermosonic and it's every time's delay time is invariableness. The interrupt working model trigger system is superior to the scan working model trigger system. It is also confirmed that the interrupt working model trigger system can used as a precise synchronization trigger system by triggering the thermosonic flip-chip bonding's data acquisition system, the press measure system and the polytec vibration measure system
