With every year the electronic industry is expanding, and with it, the density of electric components and connections on printed circuit boards (PCBs). PCBs are becoming smaller, more compact, faster, with greater efficiency and smaller weight. The global trend of electronic miniaturization brings countless advantages for consumers as well as the industry. With it the price and amount of needed material for manufacturing is decreasing, which is ideal for consumers and industry, however for the companies who manufacture PCBs this represents an enormous technological challenge due to increasingly strict requirements for accurate and precise manufacturing.
As part of my thesis, I had focused on the analysis of the effect of curved motion system guides on the accuracy of PCB production on the laser system ProtoLaser from company LPKF d.o.o. The task of my thesis is to determine if, and how, it’s possible to obtain information of table rotation from current calibration methods, which affects precision of PCB manufacturing. With the help of mathematical simulation, we further explore if it is possible to determine the required flatness of mechanical guides to achieve the required accuracy of ProtoLaser.
First part of the thesis is intended to acquaint the reader with various methods of PCB manufacturing, the background of ProtoLaser operation and its calibrations, and at the end, the background of mathematical simulation, calibration analysis and measurement principle is presented. In the second part results of measurements, simulations and calibrations analysis are represented, commented and compared together.
