During the second half of the XX. century the development of different types of electronic devices/equipment has started to be in progress. The result of this is that, in these days our life is well-equipped with several different types of electronic devices and their number is still increasing from year to year. However, this rapid increasing causing various problems within society, therefore in waste management, too. The recyclability for most of the products are hardly reachable due to their content. Hence in industry and manufacturing more strict limits and rules are applied for the production of electronic devices, firstly to reduce their pollutant content and to reach safer way of the production. For this reason the manufacturers are forced to consider the recyclability of the newly designed products plus their influence on the environment. The second biggest problem in manufacturing is the resource depletion of the raw materials.
Consequently, in my thesis I investigate the production of the different biodegradable printed circuit boards and also to carry out investigations for the development of scientific and technical knowledge. Firstly, I analyse the composition of waste and then I review the biodegradable plastic materials, basically the two main ones: cellulose-acetate (CA) & polilactid acid (PLA).Thereafter, I made a bibliographic search about the products/devices which are nowadays recyclable and made off biodegradable materials.
In my next step, I made holders from materials which were available to me. Finally, I subjected the made/completed holders under investigations, like blending test and copper clad lamination. Under the available possibilities I tried to compare the different investigations with the materials that are nowadays used in printed circuit boards.
