The physical properties of your PCB substrate and copper conductors are the main factors determining how a circuit board will heat up during operation. Circuit board thermal analysis techniques aim to predict when and where a board will heat up during operation, as well as how hot the board will get.
This important part of the analysis is geared to ensure component-level and board-level reliability, and it can influence many design decisions.
Altium Designer has the best circuit board design tools complete with a materials library to help ensure reliability. A unified PCB design package that integrates advanced layout features with a comprehensive substrate material library and production planning features.
The materials in your circuit board and components will determine how heat moves around the board during operation.
Unfortunately, PCB substrate materials are insulators that prevent heat from dissipating away from hot components. Copper conductors and plane layers can help, but there are some simple design choices that will influence the equilibrium temperature of your board as it operates. These design decisions are focused in three areas:. In addition to things like electrical fans and heat sinks, some other simple design choices can help ensure your board will run at low temperatures and will not fail prematurely.
The goal in thermal analysis for circuit board design is to determine when cooling measures like fans, heat sinks, additional copper, or thermal vias are needed to keep the temperature within limits.
The designer needs to select the maximum acceptable temperature for components in their board, and then examine how the component temperature will change based on the power it dissipates.
If the component temperature gets beyond the acceptable temperature limit, then additional cooling measures like heat sinks or fans may be needed. To start, look at the thermal impedance of a component, which is normally found in the component datasheet for integrated circuits. No matter which of these routes you take, thermal reliability starts with designing the right PCB stackup using the best PCB design software. Before implementing any other cooling measures in your circuit board layout, use the best set of PCB design tools to create the correct stackup.
Through-hole vias can be defined in the Layer Stackup Manager to span onto the back of the board beneath hot components. These basic aspects of PCB design go a long way to helping remove heat from hot components.
Altium Designer also allows users to access a PCB stackup materials library with known dielectric properties for common stackup materials. This gives designers full control over their stackup design within their PCB design software, aiding applications like high-speed boards and high current boards for power systems.
Design any stackup and select any material for your circuit board in Altium Designer. Learn more about selecting the right substrate material. Learn more about designing circuit boards with ceramic substrates. Learn more about designing your layer stack in Altium Designer.
Defining a stackup is just one important aspect of designing your board. Once the stackup is defined in your PCB design software, you can start using your PCB layout tools to place things like ground planes, copper pour, heat sinks, cooling fans, and thermal vias.
Your PCB libraries should also connect to the electronics supply chain to give you access to CAD models for fans and heatsinks. This makes it easy to find, download, and place the components you need for heat management in your circuit board layout. In addition to points like placing things like thermal vias, fans, and heat sinks, your plane and trace arrangement on each layer in your PCB will dissipate heat due to the inherent DC resistance of copper conductors in your PCB.
A DC power integrity simulator can be useful for spotting areas in your PDN with high current density, which will then lead to higher temperatures.
If these hot regions in the PCB are near a hot component, then some additional copper or heat sink may be needed to help keep the temperature low. In addition, copper in the identified region of the PDN may need to be redesigned to reduce the DC resistance in that region. Learn more about thermal pads and thermal paste. Learn more about working with active cooling components in your PCB layout.
DC power integrity simulations can help you identify hot spots in a PDN on a single layer or multiple layers simultaneously. Properly managing heat in your circuit board layout is a difficult task without the right set of PCB layout tools. Your PCB design software should provide all of these features in a single application, rather than separating everything into different programs.
Altium Designer is the only comprehensive PCB design application for any application, ranging from high power DC boards to high-speed digital products and high-frequency RF systems.
Altium Designer includes a top-notch layer stackup manager that allows you to import standard materials, define any layer arrangement you can conceive, and import unique materials. Everything you need to design reliable circuit boards is included in Altium Designer. The power of Altium Designer lies in its rules-driven design environment. Other design platforms separate your important design tools into different programs, but Altium Designer keeps you productive with a single application.
The PCB design features in Altium Designer are built to work together in a single package and will help you spot errors as you create your design. No other PCB design application gives you access to this many features for circuit board thermal analysis, layout, and manufacturing.
