PCB designers must be able to develop excellent layout designs for the proper functionality of components that use printed circuit boards. Lately, there is a huge demand for PCBs with minimal footprints. Printed circuit board designers are therefore required to employ the use of smaller components that reduce footprint significantly. Generally, components that find use here are very close to each other.
If you happen to select an incompetent layout technique, then the connection may go wrong and affect the functionality of where it will find useful. Sadly, most printed circuit board manufacturers find it hard coming up with the best layout. The greatest challenge faced is when handling the device with higher pin counts and a smaller pitch. If the layout is wrong or incompetent, rest assured that the board will fail to function as desired.
To ensure the desired functionality, it is very important to select the best layout technique available in the market. If you are in the market for the best PCB designer, look no further after comparing several companies. They must understand nearly everything to do with the board layout and ready to assist you all the way.
How to choose the proper software?
One of the best things you can do to improve the quality of your PCB design is to use quality software for the creation. Of course, some might worry that software will be expensive or difficult to use. While this is certainly a potential problem with some pieces of software, it doesn’t have to be.
Advanced Circuits offers PCB Artist, a robust piece of software that can provide you with the guidance and tools you need for your PCB design regardless of how simple or complex it might be. It offers more than is found with most other pieces of software on the market that provide similar features. One of the best features of the software is the price. It is entirely free, so you will not have to worry about paying anything when you are getting started. Whether you are a hobbyist or working for a company, you will appreciate this benefit.
While the software will have a learning curve, like any piece of software, it tends to be easy to use. Those who have any experience with PCB design should not have a problem getting started with the intuitive software.
How to choose the right components?
As a board designer, you should thoroughly study the BOM and examine the parts that go into the design. When there is sufficient space on the board, you may opt for larger components for resistors and capacitors. It is beneficial to use a 0603 or 0805 size capacitor/resistor instead of a 0402/0201. Select the smaller package version of the component if you have spacing issues. Moreover, choose your appropriate component and package based on the required current, voltage, and frequency.
Smaller components are manufactured by various vendors. It allows designers to choose alternate parts without modifying the schematic or layout, providing a timely solution for components that are not in stock. Furthermore, it is crucial to decide the appropriate size of the package during the PCB design phase. It is recommended to choose smaller packages only when necessary; otherwise, choose larger packages. Using too many small component packages can create issues during circuit board assembly, which leads to difficulties during cleaning and reworking.
How to avoid the common issues of PCB layout?
Errors in landing patterns
PCB design software packages provide libraries of electronic components. These libraries include the schematic symbol and PCB landing pattern for each component. You won’t usually have problems if you stick to these components in your design.
However, if you use components outside of these libraries then you must manually draw the schematic symbol and the PCB landing pattern. It’s easy to make mistakes especially on the landing pattern. For instance, if the pad to pad spacing is off by as little as a fraction of a millimeter, the pins won’t align properly making soldering difficult or impossible.
