Everyone makes mistakes. Of course, even PCB designers do. What’s important is you learn from your mistakes and try not to make it again. On that note, this article talks about the most common PCB errors that beginner designers often commit. If you are a beginner, it pays to read up on this topic to avoid them in your first printed circuit board.
- Over-Complicated Design
A common mistake that PCB designers make is making the layout too complicated. It usually happens because the designer is not familiar with the processes and chemistry of the PCB fabrication. It is advised that designers have to keep in mind that the goal is for the design to be practical and economical to avoid this mistake.
- Usage of Thermal Relief
More specifically, it talks about the mistake of not using thermal relief. If the designer uses this, it will be easier to make the soldering of the circuit. Often, beginners skip on using this to reduce the thermal and electrical resistance. However, you will then expect a more difficult soldering for the most part when you connect to a component pad filled with copper fill. Changing the amount of thermal relief used can deal with the connection’s resistance.
- Closely Placed Components
Some designers would place the components of the circuit board too close together. It can cause some problems including solder bridges. It is not the best that the parts are too close together because it will be hard then to probe the circuit lest the multiple components are shorted. Additionally, it will make it difficult if there is a need to replace some parts.
- Skipping the Schematic
Beginners tend to miss the schematic step when doing the designs of even the simplest circuit boards. However, the schematic is an important step that shouldn’t be skipped in the procedure. If you have a schematic and you made a mistake in the design, you can use it to find out what you did wrong and correct it right away.
- Sloppy Layout
Today, the use of PCB layout software makes it easier and quicker for engineers, designers, and even hobbyists to design their PCBs. It boosts their creativity, but can also cause the designer to make sloppy mistakes. Even when using the software, it is critical that the designer still use his knowledge to ensure no mistakes are made that will impact on the board’s functionality.
When designing PCBs, make sure that you have some design rules that the manufacturer can follow. It is crucial to have design rules to ensure that the designer or engineer can create a circuit board that is exactly what you need. At the same time, it helps to prevent any chances of mistakes such as those mentioned above.
Keep the design mistakes stated in this article and read on for more to ensure the best-printed circuit board will be made for you. It is essential to make sure that the circuit board will be functional, which you can achieve by following good practices. When you do, the assembly becomes easier, your yields will improve, and debugging errors are easy, too.
