    <br>Anyone who has ever turned up at an electronics store has witnessed a puddle in the back section of the shop, and that is circuit board manufacturing. They are typically thick, flat, and almost always silver colored substrates which are nicely covered with a grid of small copper lines and plastic pads and constitute the heart and soul of almost all electronic equipment. Without this technology, modern electronics simply would not be possible. Today’s world of mobile phones, computers, personal digital assistants, cellular phones, handhelds, digital signage, electronic billboards, and so much more rely heavily on circuitry designed and manufactured by means of circuit board manufacturing.<br>
    <br>PCB manufacturers use a variety of different processes to create their web products. Most commonly, they use computer-aided design or CAM to lay out the electronic circuit on the surface of the board. This allows them to quickly view each component in turn so that they can make changes or add to their design at anytime. Many PCB manufacturers also have the option of using surface mount or adhesive backed printed circuit boards.<br>
    <br>Most printed circuit board manufacturing uses either silver or copper traces as well as metallic paint or non-metallic coatings. The most popular of these components are the copper traces, which are used to provide electrical conductivity and conductors for the circuitry. Many companies have developed special copper traces that exhibit excellent electrical conductivity and resistivity which are extremely useful. Another popular form of electrical conductivity used today is dip wiring which has trace patterns that follow electrical waveform.<br>
    <br>The most common form of electrical coating used in pcb manufacturing is non-metallic. It is often applied to the rear or top of the circuit board to protect it from surface erosion and moisture penetration. Most of these non-metallically coated surfaces are heat treated, which improves their resistance to damage by electrical flow. Another form of non-metallic coating is polyester, which is also applied to the back or bottom of the printed circuit board. These two types of coating are also applied with varying amounts of heat treatment to improve their resistance to damage.<br>
    <br>During the manufacturing process, pcb’s are made from a variety of different materials including plastic, metal, ceramic, wood, fiberglass, and many others. Plastic pcb’s are among the most common due to their cost effectiveness and longevity. They are also usually flexible so that they are manufactured to fit into the space provided. Some companies even manufacture printed circuit boards that have flexible components such as a thin metal frame with flexible flexing components underneath. Some companies prefer to use plastic or rubber pcb’s because of their low cost and long life. Because of these benefits, many companies prefer to use plastic or rubber printed circuit boards.<br>
    <br>Once the pcb’s are created, they are typically shipped to a hole in the company’s warehouse where they are processed further. During this processing, they will be placed inside an electric depolymerized. This process will remove any excess glue, shrinkage, dirt, or grease from the surface of the web. After this process, the job is returned to the production line and ready to be printed. In the printed circuit board manufacturing process, various processes are used to create a final product.<br>
    <br>The first step is to lay down a solid topography pattern on the web. It is important to have a good solid topography pattern because it can help to guide the electrical currents through the circuit boards. The next step is to place the soldered together holes in the pcb using the electrical components. The final step is to place the printed circuit boards into the holes using the hot air pressure to solder them together.<br>
    <br>The last step is to add a clear protective layer to the top surface of the printed circuit board to prevent dust and moisture from penetrating it. After all of the design and printing is complete, the boards are placed into an electric oven at a high temperature. An automatic sprinkler system is used to spray the base laminate on the board. The system provides controlled temperatures that ensure that the board comes out clean and ready to use.<br>
