Circuits are the foundation of modern devices. Even appliances that depend upon mechanical parts or physical components to accomplish the huge part of their work need controlling circuitry. Without circuits to tell motors when and exactly how fast to run, screens what to display and components how to interact, the majority of our modern technology would fail astonishingly.

A lot of circuits are made from countless individual components integrated together as a working whole in a single unit. This typically takes the form of a non-conductive plastic wafer, generally known as a circuit board. By connecting each component it carries with metal conducting lines, the circuit board is able to create visually neat and technically complex circuits without using hundreds or even thousands of wires to join everything together.

There are many methods of circuit board assembly used in modern industry. Many of these are simply useful for temporary prototyping, like bread boarding, where each component is often inserted into a pre-made connector slot and wired together without solder. When creating circuits that need to survive the ups and downs of regular usage, constant motion or potential accidents, however, it’s important to use a more permanent technique that results in a stronger overall unit.

The printed circuit board is such an approach. It translates into hardwired circuitry that cannot be rearranged, which means that printed boards last for years. Furthermore, the fact that such circuits have very low profiles allows them to fit in a lot of devices easily.

There are several ways to develop printed circuits. Most begin as regular plastic circuit boards with one side totally coated in a really thin metal. The designer plans a pre-determined design for all the parts, and holes that correspond to the component locations are drilled into the board. Next, the design will be printed on the metal side of the board. The silkscreen ink will serve as a mask that covers the areas that have to be retained. Then, the board can be dipped into a chemical etching solution which takes away all the metal that was not covered in the printing process, leaving long conductive lines, or traces, that connect the correct holes. The components are then inserted in to these holes and then finally soldered into place, having a complete, functional circuit.

Some other printed circuits depend upon similar photoengraving methods, while others make use of milling machines to etch away the unwanted copper. Regardless of the method, circuit board assembly results in consistent circuits that function identically from one board to the next.

About the Author

Circuit board assembly is an important part of controlling your devices and ensuring they work as desired. The things you make depend entirely on the quality of the printed circuit board they contain. Make sure the end product of your work is just as good as the idea it came from by building it up from reliable components like circuit boards.
