The parameters of a schematic symbol being changed in a part editor. Here is where you need a well-developed PCB library to keep all of these parts ready for your next design.

Once the components for your design have been selected, the next task is to retain them so that you can reuse them on future designs. Many times, these component experts can also make recommendations on part or circuitry changes in case the components you specified have short life cycles. They usually have a trained procurement staff that can verify the part’s status before you build the board. Here is where your circuit board manufacturer can help. It is important to find out the component’s status and avoid those that carry are marked as NRND (not recommended for new designs), OBS (obsolete), or EOL (end of life) before committing to its use. Many times, parts are chosen for the prototype build of the board but not looked at for their longevity. Life cycle: Components will be phased out from their vendor’s inventory from time to time, which can cause problems for long-term builds of a circuit board. Delays can occur for a number of reasons including national holidays, political problems, or even natural disasters like a pandemic. Price: The cost of a component can vary from different manufacturers and distributors and should be confirmed before a commitment is made for large production runs of a circuit board.Īvailability: The parts may be within the correct price range for your project budget, but shipping delays can still undermine the circuit board build. The following three factors must also be considered when selecting a component to use on a circuit board: Before a component is selected, however, there are still a few other considerations that need to be reviewed first. Its physical package must both fit on the board along with the rest of the parts, and it must be compatible with the assembly processes that will be used to build the board. The circuitry must ultimately perform according to its specifications and will be tested with circuit simulation and analysis tools to verify this throughout the development of the board.īut, performance isn’t the only criteria that a component must match to be used successfully on a PCB. When a circuit is being developed for a printed circuit board schematic, it is obvious that the correct components must be chosen for it to operate correctly in the final design. Let’s look at how choosing the right component for your circuit from a library can help make PCB designers more productive, and how best to configure that CAD library.Ĭhoosing the Correct Component Is About More Than Just Functionality Instead, we spent a lot of time in component research, creation, verification, and modifications, which was time that would have been better spent on producing more billable work.įortunately, most PCB design CAD systems are equipped with many productivity enhancers, such as library capabilities, that can save you time and effort when you use them effectively. The only way around a problem like this was to use a reliable PCB library system, which we weren’t able to do.

Although we all got very good and very fast at doing this, it had a measurable impact on our productivity. It seemed every time we started a design for a new customer, we had to create the library parts from scratch to match their unique requirements and specifications. Unfortunately, that was also one of the worst things about it. One of the great things about working at a PCB layout service bureau was all the different board design types and styles we worked with. How the Unified Parts Search system can help you choose and use the right parts.Ĭhoosing the correct component for your design can be made easier with an organized PCB library.

Using the right components in your design is about more than just their functionality.
