The printed circuit board and module is an electronic assembly that uses copper conductors to make electrical connections between components. Printed circuit boards provide mechanical support for electronic components so that the device can be mounted in a cabinet. The design of a printed circuit board must include a specific set of steps aligned with the manufacturing process, IC packaging, and raw circuit board structure.
The mechanical structure is formed by an insulating material laminated between layers of conductors. The overall structure is plated and covered with a non-conductive solder mask, and a silk-screen material is printed on the solder mask to provide a legend for electronic components. Once these manufacturing steps are complete, the bare board is sent to PCB assembly, where components are soldered to the board and the PCBA can be tested.
PCB design has been its vertical within the electronics industry. The electrical interconnects between PCB components play an important role by providing a rigid support to hold the components and a compact package that can be integrated into the final product. Even the most basic circuit board must be carefully designed using specialized software packages, and the best software can help take the design from concept to manufacturing. In this article, we'll take a look at what a PCB is, its design details, and some important points to understand when designing circuit boards.
