Printed Circuit Boards: A Few Tips on Design Rules And Layout Methods

With advancements in technology and streamlined ordering processes, printed circuit board fabrication is attainable for anybody with some DIY electronics knowledge. Today's technology enables anyone with the desire to become a garage or basement inventors by designing and building their own custom printed circuit boards (PCB).

Design Rules and Layout Techniques for Printed Circuit Board Construction

Here are a few tips and tricks for those who are novices in printed circuit board design. There is certainly much more to learn about PCBs, but these hints should get you started.

Pick the Best 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. Click here to learn more about custom PCBs.

Work to Grids

When aligning the board components, you should utilize the visible grid or snap grid functions in the design software program. This will aid in symmetrical design layouts that will make visually appealing designs. It will also be easier to edit your design and align your tracks.

Make Certain to Separate the Grounds

Sometimes a custom printed circuit board will necessitate digital circuits and analog circuits. It is so crucial the both circuits has a unique ground. If they were to come in contact with each other, operations would be disrupted.

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. Noise can also be caused by currents from some other external circuit and/or currents coming from other outside sources. It is imperative that all internal circuits are kept apart from one another, and also kept away from any outside disturbances.

Heat Regulation

Excess heat is detrimental to a PCB's operation. This can be prevented by working with components that use a small amount of power, thus not creating much heat. Other ways to avoid heat build up are using heat sinks, adding fans to regulate temperatures, and keeping critical components away from heat sources.

The All Important Design Rule Check

More often than not PCB design software programs will contain DRC (Design Rule Checking), that enables you to find any problems with connectivity, clearance, anything else in the PCB. 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.
