Building custom circuit boards is a three-tier process consisting of the design, build, and test (or DBT) stages. Each stage is distinct yet depends on the others for overall success. The board build stage is where board quality and reliability are defined. It’s also where the tangible product that embodies your design intent is created. Producing the best representation of your design means optimizing PCBA manufacturing—and it starts with PCB fabrication. Align design specifications with the fabrication process, opt for the best type of service, and choose the right contract manufacturer (CM) to build your boards.
Tempo’s digital thread manufacturing process leads the PCBA industry in building custom, complex boards with agility and accuracy. Our integrated turnkey PCB fabrication and assembly services deliver on-demand PCBAs at the speed of innovation. For more information on PCB fabrication for your designs, contact us.
As the initial manufacturing stage, fabrication converts your outline into a PCB that accurately reflects your design. The process for building your bare board includes well-defined steps, as shown on the right. However, the equipment and materials needed for implementing each step can vary significantly. To avoid this, it is important that you acquire and follow your CM’s DFM rules and guidelines.
DFM rules and guidelines define the requirements for circuit board manufacturing that fall within industry standard regulations, especially the performance classifications set by IPC 6011. They and other associated standards specify important DFM parameters, including the following:
Important DFM Specifications:
Although inexhaustive, this list shows the importance of DFM in laying out your PCB for manufacturability.
In addition to understanding the importance of DFM when it comes to PCB fabrication, it’s necessary to know which service options are available to you. There are three types of PCB fabrication services:
PCB Fabrication Options:
Your choice of PCB fabrication service can greatly affect the quality and efficiency of the entire manufacturing process.
The final and most important step for optimizing your board build is to partner with the best PCB fabrication service provider for your design and application. Below are a few important considerations to help you decide.
