Digitization and “electronification” of things these days has caught on like a wildly spreading trend and necessity across the world. If there is a service that requires manual labour, then there is an innovator who is trying to remove human error from that process by inventing an electronic device to do the job. Paperwork these days is digitizes, with the most common example being your resume that is sent electronically to the potential employer. With this much dependence on electronics, a little insight on how things work is justified. If you’ve ever seen a broken appliance as a kid, then the most natural instinct for you must have been to break it down further, right down to its bone. All sorts of components come out of a broken appliance – including a printed circuit board. It looks like a small piece of bread, maybe even as small as a biscuit. This board is the first step for you if you wish to learn about electronics. A circuit board works as the brain of a circuit and controls what the device does. When a remote-controlled toy car responds to your commands from the remote, it is because of the PCB that’s in there. It tells your device what to do next. Circuit board manufacturing itself has seen many improvements since its inception, with the most prominently changing characteristic being its size and complexity. Improved processes and efficiency of manufacturing has made it possible to build smaller circuit boards housing more complex circuits. The ramifications of this innovation can be seen in the form of electronics getting smaller by the day. From a mobile phone to everything on your smartwatch – that is what is possible. Smaller devices like hearing aids and stuff also have circuit boards. Basically, anything that is electronic needs a circuit board to “keep” the components aligned in the required order to receive signals according to user commands. A circuit board has varied standards of quality and accuracy based on the nature of application for which it is manufactured. A toy car does not need quality and accuracy standards as high as those required for aeronautics and medical science industries. The complexity of circuit and efficiency of components is a factor that is counted in high regards when it comes to serious fields of PCB application like space programs and terminal illness treatment. A printed circuit board makes sure that the processor connects to all the components on the board and the signals are relayed effectively. The process of etching needs particular care, as this creates a path for the electrical signals to travel and complete the circuit. Process improvement has led to technology efficiency reaching a point where “etching” is not needed – the traces can be directly “painted” on to the board instead of having to scrape off unnecessary metal. Scraping and discarding ultimately leads to some wastage. PCB technology is still improving, and the future will bring devices close to what one sees in sci-fi flicks.
