A PCB you are using in your finished product undergoes a thorough PCB fabrication assembly procedure. First, the PCB must be manufactured using copper metallography and silkscreen printing. The printed circuit boards are then mounted on it after the final printing finish. This is the main assembling procedure.
If you want to assemble a PCB yourself, first make sure you have all the needed materials for the process, including detailed information on how the PCB should look like. You should be able to determine which color would go best with your electronic equipment. Check if your printer supports transparent and clear images. For a perfect PCB fabrication process, you need to find a professional PCB manufacturer.
After considering the design phase, the next step is PCB designing. There are two formats in which you can do PCB design: the software-based one and the physical. The software-based PCB design phase involves creating a circuit board from a CAD drawing. You will use specialized software to create a physical PCB prototype. You will get a physical model when all the testing is done.
In the software-based PCB design phase, you will use a standard graphical editor to generate a PCB design. PCB designers will produce PCB through a variety of methods, including AutoCAD, PKSA, and Solidworks. You can also visualize the end product on your computer screen.
Next is PCB testing. This phase involves physical inspection and simulation of a final PCB. This also helps in determining any manufacturing issues that may be present. It checks the components for acceptability, programmable logic elements (PLLs), and resistive or conductive metallic layer thickness. It also checks the overall reliability of the device. The last stage of testing is usually performed after all the above checks are done, and PCB is ready for going into production.
The final phase is PCB fabrication assembly, and this is done by physically assembling all components. This should be done carefully and securely. Some of the popular electronics products that use this process are cellular phones, medical devices, LCDs, DVD players, personal digital assistants (PDAs), watches, and speakers. It also serves as test automation or QA. The entire assembly process also has a control center – a software system that monitors and controls every phase.
The entire assembly process starts from designing the layout, planning to manufacture, and finishing touches on the finished product. The entire process can take anywhere from three to six weeks, depending upon the requirements.
