Even though initially while starting to design, we keep aside the guidelines to be followed for PCB designing in order to focus more on the design of the circuit and the component selections, at any time later in the process, we have to provide more time and focus our efforts more on the PCB designing guidelines that helps in developing a design that is far distant from poor development in the physical reality. Altium provides you with efficient and professional PCB design software.
An inefficient design of the PCB could also prove to be a troublesome design that is hard to be fabricated in the production process. In this article, we will discuss about some of the important points that are essential to considered while in the process of a PCB designing. To achieve a completely design software for your production requirements, follow the below mentioned guidelines. Let us look at the five guidelines to be followed in any PCB designing:
Fine-Tune Your Component Placement
This particular process is both an art and science that requires a strategic consideration of the prime real estate that is there on your board. Even though it is a challenging process, the placement of your components on the board will determine the ease in the manufacturing of your board and also in achieving the overall requirements of your PCB designing.
Placing Your Power, Ground & Signal Traces
The next step in PCB designing after the completion of placing your components is to route the power, signal traces and ground to ensure that the signals have a clean and disturbance free path for travelling. The below mentioned are the guidelines to be followed for achieving this process:
- Orienting Power and Ground Planes
- Connecting Signal Traces
- Defining Net Widths
Keeping Things Separate
The third step in achieving a successful PCB designing after the completion of the first two steps in a successful manner is to anticipate and avoid any issues that may arise in the complete process such as interference of large voltage in power circuits and current spikes in the low voltage and current control circuits. In order to avoid such issues, the following guidelines should be followed:
- Maintain a safe distance between the power ground and control ground for each and every power supply stage.
- In order to minimize the risk of any power circuit interference and to protect the control signals, in case of the ground plane in the middle layer, then make sure that a small impedance path is placed.
- Another important guideline to be followed in PCB designing is to reduce the capacitive coupling due to the placement of a large ground plane and the lines routed above and under it, try to have your analog ground crossed only by analog lines.
Combating Heating Issues
If the heat issues are causing damages to the board or even the circuit performance is degraded, then follow the below mentioned guidelines:
- Identifying Troublesome Components
- Adding Thermal Reliefs
Checking Your Work
The final and the foremost important thing to be followed to ensure that everything in your process of PCB designing has gone well and you will have a perfect output is that to perform a thorough and complete checking of the complete design project.
