Common Layout Tactics and Design Rules in Printed Circuit Board Design and Fabrication

If you’re new to custom PCB design, we’ve put together are short list of design rules and techniques to look out for. There are certainly many more, but these will help you get on the right track for your custom PCB design.

Choose Good Materials

It doesn’t matter if you are using a PCB manufacturer or building your own custom PCB, you should always select the highest quality materials. The board will be much more durable and dependable as a result.

Using Grids

Use your design software’s visible grid or snap grid functionality to help you line up your board’s components. Using this grid method allows for symmetrical designs that look much cleaner. Track alignment and design is also made easier by using this method.

Make Certain to Separate the Grounds

In the event that your custom PCB needs both analog and digital circuits, be sure that each one of those circuits has a separate ground. Should those two circuits meet, the operation of the board would certainly be interrupted. For more information about custom PCBs, click here.

Prevent Noise

Noise is often created by tracks that are laid too close together. Currents from different circuits can cause noise which ultimately disturbs the operation of the circuit. Sometimes noise can also stem from currents from exterior circuits or currents from exterior electrical sources. If you are creating your own custom printed circuit board, it is crucial that you keep each internal circuit separate from the others, and keep all of the internal circuits safe from external interruptions.

Heat Regulation

Excess heat is detrimental to a PCB’s operation. Prevent overheating by utilizing components that do not require much power. Using fans, separating components from areas of high heat, and utilizing heat sinks are also ways to eliminate heat build-up.

Test the Design Rules

Your PCB design software most likely has automated Design Rule Checking (DRC) that will check your custom PCB design for connectivity, clearance, and other design errors. Your design software may also have real-time DRC that checks your design as you are designing. The feature will not allow you to place tracks too closely or make any mistakes in the board design.
