It becomes the responsibility of the PCB designer to manage the heat dissipated by the components used in the PCB. The following are guidelines for effective thermal management of heat generated by components on board.
Even though multilayer PCB designs are more common these days and the above tutorial too assumes a multilayer PCB design, single layer PCB still find a place in the PCB designers’ repertoire. The electronics hobbyist who is very cost conscious and whose circuits are very low complexity, a single layer PCB may be the ideal choice. In a single layer PCB, the components are mounted on the top side of the PCB and the routing is done on the bottom side. Routing a single layer pcb may prove to be tricky since there is only one layer to route. It is futile to try and comply to EMC rules. Use jumper links to route traces and avoid too much of crisscrossing. Sometimes it becomes impossible to route a connection without using a jumper link on a single layer board.
With a wide range of free PCB design software available, it would prove very cost effective for an electronics hobbyist to do the PCB layout design himself, rather than going to a professional. Attempting to do a point to point wiring on general purpose boards would prove to be a hassle and would be less robust. Also any sort of troubleshooting would prove to be very tedious. Hope this tutorial has enabled understanding the basics of PCB design.
