Here is the step by step PCB fabrication process: The most common type of PCB board is FR-4, other options are CEM, PTFE, Polyamide etc. Substrate Material: The substrate of the PCB board is important and is usually selected based on the performance required. Single Sided or Double Sided: This determines if you have components placed on one side of the board or on both sides of the board. As multiple layers can be used to route connections on the board. Multiple layer boards are more compact and usually smaller in size. PCB Board Layers: Most printed circuit boards have multiple layers. Type of Board: This is the physical attribute of the board – they can be Rigid, Rigid-Flex, Flexible, HDI (High Density), RF (High Frequency) or a Burn-In board. Some key parameters that a user must specify are:
Inspection tests are performed to detect early-stage failures.
After rigorous testing and real-time usage, the PCB is considered as standard and leads to the production fabrication.
Actual PCB fabrication starts with the Prototype PCB, where the manufacturer fabricates the first PCB as per the given specifications. The Gerber file is the industry standard to maintain the record of PCB specifications. Modern PCB fabrication techniques are more application-specific, which means a specific PCB is fabricated according to the requirement while keeping the quality intact.Ĭustomers design the PCB board using a software to develop a ‘Gerber file’ which is then sent to the manufacturer. PCB fabrication is a process of putting together all the PCB layers, starting from ‘Base’ to the ‘Circuit’ layer. Various components such as inductors, capacitors, resistors, ICs and other devices are soldered on to the board. A PCB is the base of almost every electrical or electronic system. PCB Fabrication or Printed Circuit Board manufacturing is the process in which a board is fabricated that is used to support and connect various electronic/electrical components to one another.
