A good application example of the machine is the casting of an air pressure sensor (dimensions: 2 x 2 x2.1 mm): To protect the sensor against outdoor influence like humidity and water, an exact cast volume of 1.3 µl is required. It has to be provided at each cycle of 2.7 seconds per component. During application it is fundamental not to touch the sensor although the dispensing needle works with a distance to the sensor´s surface of 0.15 µm. The system is developed and manufactures by machine builder Häcker Automation, Germany, and was presented at Apex by Häckers US sales representative Ricmar (Hyannis Court, California). Häcker has as well multi chip and 3D micro assembly systems, which come custom made to achieve applications in automotive, medical and other.
