Circuit board designs

Circuit board designs continue to become increasingly complex. With the growing demand for smaller components and devices that are more energy-efficient, it is becoming more difficult to design circuit boards with all of the functionality needed. This can lead to a higher risk of mistakes during the PCB design process, which can ultimately result in power failures. Fortunately, there are several steps that can be taken to minimize the risks of designing and manufacturing a circuit board.

Before the physical layout can begin, it is important to determine the exact functions that the circuit board needs to perform. This can be done by defining the desired components, their location, and other variables. This will also allow the designer to calculate how large the board should be in order to have enough space for everything.

Another key step is identifying the materials and components that will be used in the circuit board. Some of these items may be hard to find or expensive, while others may have specific design requirements. Taking the time to ensure that the optimal materials and components are selected will help to reduce design costs, improve performance, and reduce the overall risk of the circuit board’s failure.

Incorrectly sized traces are one of the most common causes of circuit board failures. Traces must be suitably sized to prevent them from overheating or failing due to excess current. While there are numerous calculators that can be used to size traces, designers should also be sure to consider other factors such as copper thickness and track width. Traces that are too thin will present a greater resistance to the passage of current and will require more heat dissipation. Traces that are too wide can be susceptible to interference and signal attenuation.

Using the proper layout techniques can also help to prevent power failures. This includes avoiding acute angles in the layout, which can cause acid traps that can damage the components and lead to failure. Ideally, these angles should be avoided, but they can sometimes be unavoidable. In these cases, a simple redesign of the layout can prevent the circuit board from failing and causing power failures.

Other common causes of circuit board failure include the use of inappropriate components and physical damage during assembly and production. While the vast majority of circuit boards function normally, these defects can still cause power failures in some instances. In some cases, these defects are caused by components that have been damaged in transit.

Regardless of the cause of the failure, it is important to be aware that there are always risks associated with the design and manufacture of circuit boards. However, by following best practices and implementing design techniques such as avoiding via holes (type 1 or type 2) where possible, optimizing the copper thickness, minimizing the number of layers, and using differential signaling, designers can significantly reduce the risk of their circuit boards failing in the field. In addition, using software such as Valor NPI can enable manufacturers to practice design for manufacturability (DFM), reducing costs and reducing manufacturing times.
