Tiivistelmä
The milling machine at the Myyrmäki campus at Metropolia is used on a number of Engineering courses. Since there is no certainty about the precision of the aforementioned milling machine, it is unclear how much the production might affect the quality of the resulting printing circuit boards. Purpose of this project was to test the milling machine to get an estimation of how precise milling it is capable of.
The objective of this thesis project was to print the designed printed circuit boards using the milling machine at the Myyrmäki campus and then compare them to the printed circuit boards produced elsewhere. As a first step of the project, a printed circuit board concept was chosen to be a band-pass microstrip line filter. Next, mathematical calculations were performed to determine the dimensions of the filter, which were then confirmed by software simulations. Finally, the printed circuit boards were produced at Metropolia, as well as two electronics companies abroad, and the circuit boards were compared to each other and tested.
As a result of the project work, it was established that the Metropolia’s milling machine was not able to fulfill the set requirements. A conclusion was made that using that milling machine for such precise production is not recommended, and alternative options were suggested.
