Design for Manufacturability - Perspectives from a Manufacturing Engineer
This paper will examine a few key areas of PCB design and manufacturing that can have a substantial impact on product reliability and how to mitigate reliability risks by deploying design for manufacturability (DFM) best practices. It will also explore the dependencies between the design and manufacturing processes.

Summary
The quality and reliability of printed circuit board assemblies (PCBAs) is highly dependent upon the PCB fabricator and the PCB assembler. However, PCB design also plays a critical role and can have a significant impact on the success or failure of the manufacturing suppliers.
Today, designing and manufacturing PCBAs is increasingly difficult due to higher lead-free processing temperatures, the increasing density of electronic assemblies, and the use of smaller and smaller components. Not only does this create challenges for PCB designers, but it also increases the complexity of the PCBA manufacturing processes and puts additional demand on those manufacturing suppliers.
This paper will examine a few key areas of PCB design and manufacturing that can have a substantial impact on product reliability and how to mitigate reliability risks by deploying design for manufacturability (DFM) best practices. It will also explore the dependencies between the design and manufacturing processes.
Conclusions
The deployment of a DFM process by electronics product designers is an excellent way to improve both the manufacturability and reliability of their products. Careful consideration of DFM best practices should have a positive impact on overall product cost and reliability which will ultimately lead to improved customer satisfaction.
