How Manufacturing Processes Can Impact Reliability in RF Circuits

Posted by Stephanie Weaver on Wed, Aug 01, 2018 @ 12:19 PM

When you consider the RF applications utilized in mission critical C5ISR environments, your contract manufacturer (CM) must comprehend the issues and challenges related to manufacturing processes in RF, but also have a deep understanding of the failure mechanisms that can cause defects.

RF design is inherently more complex than any other type of design. This is because of the unique issues that must be addressed due to the extremely high frequencies of operation for these applications.  For example, there are inherent challenges with power control, grounding structures, printed wiring board (PWB) stack-ups, laminate and surface finish selection, characteristic impedance control, signal path configurations, connectorization, pad geometries, solder mask, conformal coating, surface parasitics, exposure to harsh environments, fabrication effects, via sizing, component selection, and manufacturing process impacts.  These numerous issues must be well understood by your CM or the potential for failure is magnified.

Processes Unique Among Engineering Manufacturing Companies

Posted by Laura Austin on Thu, Feb 07, 2013 @ 07:00 AM

Finding the time to do all of the processes required during a manufacturing job might seem impossible, but there are ways to ensure that your product is the best for your customers without having to spend so much time and money in the Research and Development stage. Instead of just shipping out your designs and calling it a day, you need to understand all of the different processes which can and should be done by engineering manufacturing companies that you hire to do your project. This is especially true when you are handling electronic components.
