Trüktraadid

Trüktraadid, often translated as "printed wires" or "circuit traces," are conductive pathways on a printed circuit board (PCB) that connect electronic components. These traces are typically made of copper, which is etched away from a copper-clad laminate material to leave behind the desired conductive patterns. The process of creating these patterns is known as photolithography.

The design of trüktraadid is a crucial aspect of PCB layout. Factors such as trace width, thickness, and spacing are determined by the electrical current they will carry, the signal frequencies involved, and manufacturing capabilities. Wider traces are used for higher currents to prevent overheating, while thinner traces can be used for lower currents and signal lines. The spacing between traces is important to prevent short circuits and to manage electromagnetic interference (EMI).

In modern electronics, PCBs can have multiple layers of trüktraadid. These layers are interconnected by vias, which are plated through-holes that allow electrical signals to pass from one layer to another. The complexity of PCB designs, with their intricate networks of trüktraadid, enables the miniaturization and functionality of electronic devices we use daily.
