A printed circuit board (PCB) is an electronic component that connects different electronic components together. Designing a PCB is a complicated process that requires high precision. In the design process, some common errors will inevitably occur. These error problems are to help everyone avoid them in time.
Common PCB design errors
Here are some of the most common mistakes you make when designing a PCB, look at them and make sure you avoid them.
Choose the wrong design tool:
Choosing the right tool is one of the most important and fundamental steps in successfully designing a PCB. Choosing the wrong or inefficient design tool will only create problems such as design creation time delays and increased manufacturing costs. Therefore, it is always recommended to choose the most suitable PCB. The tools required for design have many easy-to-use Electronic Design Automation (EDA) software packages to choose from.
Inappropriate layout techniques:
PCB designers need to lay out complex designs to design smaller, faster devices. As the demand for the smallest footprint circuits continues to grow, PCB designers need to use smaller components to reduce footprint. Usually, these components are closer together. If you choose an inefficient layout technique, there is a danger of a connection error or non-compliance. Therefore, when using components with smaller pitches and more pins, it is important to choose the appropriate board layout technique.
The thickness of the copper is incorrect:
Many designers often choose one ounce of copper as the finished thickness. One ounce of copper usually cannot confirm whether there is enough plating in the hole. To ensure your design is successful, you must specify the required parameters. For successful design, it is recommended to select the finished product. The thickness is 1 to 2 ounces of copper per square foot.
The decoupling capacitor is not placed correctly:
Decoupling capacitors are devices that help maintain a stable voltage. These capacitors are present on the power rail. To be effective, these capacitors should be placed very close to the pins that require a stable voltage. If the capacitors are placed incorrectly and away from the required voltage. The pins, the capacitor will not work properly.
Unable to back up your work:
In order to achieve perfect results in the PCB design process, different software and data were used. For example, EDA software can help designers create complex PCB designs. Because of the high flexibility and speed of the software, data can be easily lost even before data is saved. To avoid this, be sure to save the data frequently. It is recommended to create savepoints so that even if one storage point is corrupted, other storage points are still protected and saved.
Lack of design review:
Design review is also considered to be one of the most important elements in the PCB design process. Design reviews involve reviewing design features, PCB functions, and circuit interconnection. Design reviews can be helpful in avoiding the most common design errors. In addition, it is always good to let others review the design because he/she may find errors that were not noticed earlier.
Lack of communication:
Fatigue, stress, and multitasking are factors that affect productivity. These factors lead to miscommunication, which can lead to increased operating time and cost. To avoid this, it is recommended to communicate properly, which will provide the circuit designer with the actual design needed. time. This can further help achieve the promised delivery date.
These are some of the most common mistakes that can occur during the PCB design process, ensuring that all of the above points are followed. These points will help you design a successful PCB on your first attempt. If you don't consider the above points, then you may end up Get expensive, ineffective prototypes that take longer to get into the market.
