Vacuum and resin dosing.
The complexity of manufacturing technology sometimes requires unusual solutions to guarantee the correct functioning of the finished product. The continuous miniaturisation of electronics and their very complex construction complicate the correct dosing process (e.g. resin dosing). In this case, dosing using classical solutions may not work and advanced machines using vacuum will be necessary.
????Vacuum is the state that prevails in an isolated system (e.g. a vacuum chamber in a machine) by removing e.g. the filling air within it. Interestingly, gas molecules are always present to a greater or lesser extent in a vacuum. A vacuum is therefore defined as an area that is filled with a gas that is at a pressure significantly lower than atmospheric pressure. A commonly used unit to define the vacuum level is [bar or mbar]. We assume a range of pressure values for vacuum from 0…1 bar (assuming absolute pressure level as a reference).
The use of dosing technology (e.g. resin dosing) in which vacuum is used makes it possible:
????in the case of complex construction, to accurately reach the material in the most inaccessible places,
????the application of a contamination-free and bubble-free mixture.
At APCom, we too take advantage of the benefits offered by the vacuum environment. We would like to show you advanced dispenser with fully automated chambers designed for the application of materials under reduced pressure.
