A printed circuit board, or PCB, is a self-sufficient unit of interlink electronic components like capacitors, resistors or ICs present in devices ranging from common house hold electronic devices, or pagers, and radios to sophisticated radar and computer systems. Printed circuit boards (PCBs) are thin boards and contain insulating material, with a metal coated surface. Sometimes on both the top and bottom. Etches are made in the metal with acid to create pathways for electricity to travel among various components. Such components are mount on surface on the board with solder.
Printed circuit board assembly consists of multiple step process. After the completion of printed circuit board (PCB) , electronic components must attach to form a functional printed circuit assembly. Surface mount technology (SMT) is preferable to attach components or hole technology is also better. In surface-mount (SMT – surface mount technology) construction, pads or lands are better to place components on the outer surfaces of the PCB. In through-hole construction, component leads insert in holes. Component leads are electrically and attach mechanically to the board with a molten metal solder in both types of construction.
Different soldering techniques are available to attach components to PCB. SMT placement machines or re-flow ovens are used for high volume productions. Small volume prototypes are done by skilled technicians by hands under a microscope, using tweezers and a fine tip soldering iron.In test procedure, the assembled printed circuit boards are placed into a fixture that brings electrical power to the boards to make them live functioning boards.All active boards is then placed into an environmental stress system (ESS) chamber that will cycle between high and low temperature regimes for a number of cycles to determine if these stresses will initiate failures in the assembled boards. It is important to rework if board fails the test and technicians may be solder and replace failed components.

Electronic devices contain components that require soldering for connecting them either to each other to terminal strips and tube sockets. Now a day’s printed circuit boards have replaced all of them because of their reduced size and cheaper prices. Today, just about each and every electronic appliance in your home contains a printed circuit board of some type. For instance, computers, laptops, printers, mobile phones, TV, washing machines, refrigerators, musical instrument. Moreover, coffee makers and digital clocks, microwave ovens, telephone answering machines also contain PCB board.
