using either hole or surface mount technology. The tracks allow for the connection of circuit pieces such as integrated chips, capacitors, resistors etc. The PCB consists of a board with inner copper layers that are engraved during the manufacturing process leaving conductive tracks of copper. Single and double-sided PCB is simple but multilayer boards contain three or more layers and are used for sophisticated industrial products such as microprocessors, variable speed drivers, Programmable Logic Controllers, etc. PCBs are found in almost every electrical appliance such as computers, monitors, cell phones, industrial robots, automated machinery, etc.īased on the number of layers, PCBs are classified as single-sided, double-sided and multilayer boards. Printed Circuit Boards (PCBs) are the basic building blocks of electronic devices that are used to connect different electrical and electronic components together by using electrically conductive tracks.

It is not easy to locate the originating fault in a non-functioning PCB assembly and many consider it a “black art”, however a preliminary visual inspection of the PCB assembly by a trained eye can provide a lot of clues about the status of the board and associated components plugged into that board. When repairing a PCB, identification and locating the exact failure is paramount as one bad component can damage many others on the same board known as the domino effect. As PCBs can these days be highly complex, troubleshooting and repairing the PCBs and the components mounted on them does require patience, intricate technical knowledge, and the right replacment parts. Like any other electronic part, the PCBs and the components mounted on them can fail, and as we at Rom-Control have seen, frequently do. So how do you diagnose and fix a PCB? Background Rom-Control’s core business is refurbishing control systems which usually includes a failed circuit board (PCB).
