Common Printed Circuit Board Problems - Design
Today, the world is so full of electronic devices that most people don't realize how many printed circuit boards they encounter daily. Kitchen appliances, voice-activated home assistants, mobile devices, entertainment systems, toys, work-stations, and the family car are just a few examples. Providing the world with all of these electronics requires skilled manufacturers and precisely created printed circuit board designs. Yet many of these fundamental designs have frequent problems that delay or derail their manufacturing.

In this first of a multi-article series on circuit board problems, we will look at some of the common issues associated with a PCB design. Later articles will explore the different issues related to printed circuit boards in various aspects of their manufacturing. However, a circuit board begins with its design and layout. Therefore, here are some common printed circuit board problems in design to know to avoid manufacturing delays.

Common Problems before PCB Design Begins
Before circuit board design begins, designers should take some basic steps to ensure that the project can be completed successfully, for instance, management and scheduling. Time and resources have to be allocated for the project, and this includes a buffer for design changes or errors that require altering the schematic and the layout. Too often, PCB designers are pushed to their limits to get a project done, resulting in missed schedules, errors, or incomplete work.

Another area to focus on is the PCB design tools that will be used. Are your users proficient in the necessary tools? Do you have the appropriate CAD libraries in place? Are your company design and drafting standards incorporated into the tools to streamline the design process? These may seem like nit-picky points, but a design department will run more efficiently if all these pieces are in place before work begins. Now let's look at six of the most common problems in PCB design that can impact manufacturing.
