When that happens, it’s important to come at the situation with a bit of strategy in terms of component arrangement. Sometimes, rotating your components is simply not enough. This creates additional surface area and helps dissipate more heat, faster, effectively turning a portion of the PCB design into a heatsink. One quick tip to help you get around high-heat-related issues is to add extra copper around surface mount components. Heat will always be a problem, but it is not insurmountable. In some cases, that might be enough to compromise the board material itself, particularly if you’re using something like FR-4 rather than a material designed to handle high levels of heat. Another challenge is that those components create heat, and the closer they’re packed, the more heat builds up in the board. One of those is that without the appropriate amount of spacing, you lack room for wire routing.

Why is that? You’ll find several reasons. And, make no mistake, component spacing matters a lot. Simply put, the more components you add to a board, the more cramped they become within the design.

However, what is an advantage for end users can be a challenge for designers. The more components on a board, the more functionality it supports, and the more users can do with the device. That’s great from an end-user standpoint. Today’s circuit boards support far more components per square centimetre than ever before. If they are easy to probe then they are easy to test. If nodes aren’t accessible, testing will be even harder whatever type of nodes you have used. This could help solve your design issues and solve issues when testing. Perhaps the most important tip on our list is this – Node accessibility. In this post, we explore some of the most important elements of successful PCB design and our top 8 layout tips that you should know. We can’t go a day without relying on a PCB somewhere! And as a result, PCB design is more important than ever. Your smartwatch/fitness tracker, your laptop or your mobile. PCB’s are all around us and we are probably never more than a metre away from a PCB at all times.
