Printed circuit boards (PCB) are an important piece for many different inventions, patents and prototypes. These circuit boards help to keep computers running, allowing for the different energy exchanges and connections necessary for an invention to work. PCB fabrication is the process that brings these different circuit boards to life. It is important for inventors to work with manufacturers as they work on their prototypes. Inventors need to keep PCB fabrication in mind as they work to create their own processes and products. PCB fabrication can change the way a prototype or product is designed and created. Inventors who fail to work with manufacturers in the PCB fabrication process may fail to design their own prototypes correctly. Inventors must fully understand the process behind PCB fabrication. PCB fabrication is a calculated science that creates printed circuit boards quickly and efficiently. PCB fabrication is the step-by-step process used to create the necessary pieces for the circuit board. These pieces and materials include copper laminate, drill board and tin lead plate. The manufacturer then runs each board through testing, routing or scoring. The piece will be inspected and cleaned, and will finally be packaged for use. Inventors should talk to manufacturers about their processes and about the PCBs they create. Inventors planning to use printed circuit boards in their prototypes need to make sure that the board fits in the prototype itself, and that the prototype provides the correct connections. This information simply covers the basics of PCB fabrication and how it relates to prototypes. Inventors need to collaborate with manufacturers to fully understand how this process works with their own processes and prototypes.
