4 Common Mistakes In PCB Design

The role of a PCB designer is a very important one but sometimes, things can get a little overwhelming when a deadline is growing closer. When this happens, common mistakes tend to happen and although they are often easy to make, they can cause serious problems with the overall design.

In this article, we are going to look at some of the common mistakes in PCB design. Keep reading if you’d like to find out more about these common mistakes.

Incorrect Landing Patterns

One of the most common mistakes that people make when they are working on a design PCB project is in adding the wrong landing patterns. If you are using components that aren’t in the library then you might find that you need to draw the landing pattern yourself. This can then lead to problems when the incorrect landing pattern is used. Try to avoid this as you could make the PCB very hard to solder.

Incorrect Wireless Antenna Layout

If you are planning on having wireless functionality in your PCB then you are going to need to make sure that you avoid this common mistake in PCB design. It is really important that you have a microstrip that is connecting the antenna and the transceiver. You will also need to have an LC matching circuit in your design. Try to avoid making the common mistake of leaving these things out of the design as this will affect the overall functionality.

Lack Of Width For Power Traces

Another common mistake in PCB design is forgetting to leave a wide enough space for the power traces. Depending on the location of the trace, you will find that you need to have a different width. Those who forget specifying the temperature rise for particular traces can also come across problems in this area.

Make sure that you allow for the right amount of space for your power traces and your circuit board will be more effective.

Leaving Documentation To The End

Finally, another common mistake in PCB design is in regard to the documentation that needs to be sent on to the manufacturer. Many people focus on their design and forget to compile these documents as they go, and this can cause confusion at the end. Make sure to keep track of your BOM and other documents to ensure that you aren’t left with a lot of work at the end of your project

Final Thoughts

As a PCB designer, it is really important that you can recognise the common mistakes made by others and figure out how to avoid them in the future. You should always make sure that you are gathering your documentation as you go and that you leave enough width for your power traces to be added.

Make sure to take on board the advice that we have given you in this article and you should be able to avoid these mistakes in the future.
