“…During this simulation, the heat flow was gradually removed by the longer copper paths from the heated area and thereby cooled. The paths, which were short or directly ended in the heated area, warmed to a higher temperature [9,10]. The direct influence of unheated copper paths heated by conductive copper paths.…”

“…For this calculation, we selected the combination of epoxide resin and copper. In the literature [2,9], we found the basic characteristics of the used materials needed for calculation - Table 1. The calculation shows the value of depending force depending on temperature variation, which is necessary to divide the copper layer from the surface of epoxide resin.…”

This paper focused on the modeling of ecological PCB. Due to the high increase in the production of electronic waste, which contains a whole range of usable components, it is necessary to recycle it. About the study of the issue, we have proposed a solution for the separation of conductive paths from plastic and taking into account the legislative approaches and taking into account the existing methods of PCB separation, the composition, and production of PCBs and also the binders used in PCBs. We used the knowledge of process engineering to design a mathematical description of temperature fields in PCB and stress. To a great extent, we have devoted ourselves to the simulation experiments of PCB heating and cooling and the determination of temperature fields and stress due to temperature, cyclic mechanical stresses due to temperature. The simulation is performed in the Pro/ENGINEER and COMSOL Multiphysics® software environments, because of the possibility of solving multi-physical problems. Outputs from computer simulations are the initial stage for designing an eco-friendly way of recycling PCBs. In the future, we will focus on the more difficult issue of recycling multilayer PCBs. The development of new criteria for PCB recycling has opened new possibilities of treatment for used materials.

“…The weights of individual materials depend primarily on the type of DPS. One ton of PCB waste can be 120-150 kg of copper, 10-15 kg of tin and lead and up to 10 kg of gold, silver, and platinum [4,11].…”

Modeling of the ecological separation process of printed circuit boards

The content of this paper is the modeling of the stress in the printed circuit board due to the cyclic thermal stress for its ecological recycling. Cyclic thermal stresses result in separation of copper conduction paths and plastic plates due to different longitudinal expansion. For separation, it was important to determine the minimum temperature of the cyclical changes to separate the conductive copper paths and the plastic. We use mathematical modeling tools to describe the course of temperature fields in the PCB during heating and reheating. We conducted some simulation experiments in the Pro/ENGINEER programming environment to know the waveforms and stresses of the PCBs during the cyclic loading cycle. From experiments conducted in the laboratory, we have verified that the process of temperature separation is feasible for designing an eco-friendly way of recycling PCBs.
