PCB Fabrication Process
The intricate process of PCB fabrication encompasses a series of meticulously coordinated steps. It commences with the selection of suitable substrate material, considering factors like electrical performance and thermal characteristics. Engineers then design the circuit layout, optimizing signal integrity and power distribution. During photoresist application, a light-sensitive layer aids in transferring the circuit pattern onto the substrate. Chemical etching removes excess copper, leaving the desired copper traces. Finally, precise component placement and soldering ensure stable electrical connections, culminating in fully functional and dependable printed circuit boards that power the diverse array of electronic devices that have become integral to modern life.
Multilayer PCBs enable complex designs, surface mount technology (SMT) improves assembly efficiency, and high-density interconnects (HDI) achieve greater circuit density.
