A Review of PCB Thermal Resistance Management with Thermal Vias Design of PCBs and thermal management are intimately linked as thermal problems are known to significantly reduce the useful lifetime of a circuit board and components. Heat that is generated in a circuit board by active and passive components tends to be confined near the components, leading to a high-temperature increase due to the low thermal conductivity of most circuit board substrates. Frequent cycling of a circuit board and components Read Article
Designing Thermal Management Systems for Avionics Thermal Management: Designing Aircraft Avionics Cooling Systems The physical and electrical demands on PCBs in avionics systems are among the most intense in all engineering fields. These systems must withstand significant mechanical demands while remaining within an acceptable temperature range. Within aerospace engineering, design techniques for thermal management for avionics systems is an active area of development as more mechanical systems are replaced with equivalent electronic systems. In addition to Read Article
Thermal Relief Design Guide for Your PCB Thermal Relief Design Guide The CAD tools in Altium are ideal for thermal relief design for SMD pads and through-hole pins. Read Article
PCB Thermal Resistance: Theory and Management PCB Thermal Resistance: Theory and Management The thermal conductivity of your PCB material stackup and arrangement of copper conductors are important factors that determine the thermal performance of your circuit board. You will likely need to include strategically placed thermal vias, a heat sink on each active component and power electronics, and active cooling measures near any other heat source on your circuit board. Copper in printed circuits has high thermal conductivity, while FR4 Read Article
Thermal Via Management for PCBs Thermal Vias Management for PCB Designs An active component can act like a powerful heat source in your board, ultimately determining the equilibrium temperature in your PCB. Frequent cycling between high and low temperatures, as well as running active components at high temperature for extended periods of time, will reduce the longevity of your system and can lead to premature component or conductor failure. These heat transfer and temperature problems can be prevented with a thermal Read Article
Thermal Conductivity and Thermal Management for Printed Circuit Boards Thermal Conductivity and Thermal Management for Printed Circuit Boards The physical properties of your PCB substrates and copper conductors are the primary factors that determine how it will perform under pressure. Thermal properties, rigidity, dispersion, relative permittivity, and more will affect signal integrity, thermal management, and mechanical performance of your circuit board. When it comes to thermal conductivity, choosing the right substrate can help you combat temperature rise in your board with Read Article
Managing Your Circuit Board Parts in Altium Designer Managing Your Circuit Board Parts in Altium Designer There’s a multitude of component manufacturers, and each produces a huge number of components. No one can keep track of all information for every circuit board part. PCB components contain more information than just electrical specifications. Your PCB components also contain pin layouts, schematic symbols, SPICE model information, and even 3D models. Today’s PCB design teams need solutions to help them keep their circuit board parts and libraries Read Article
Powerful Design Software that Leaves Nothing to Chance on Your PCB Fabrication Drawing Powerful Design Software that Leaves Nothing to Chance on Your PCB Fabrication Drawing Whenever a design needs to be prepared for manufacturing, designers need to prepare multiple pieces of documentation to help them get into fabrication. In addition to supplying copies of design files, PCB designers need to provide standard fabrication and assembly drawings to thoroughly communicate their design intent to a manufacturer. A PCB designer shouldn’t have to use external drafting tools to create a PCB fabrication drawing and other Read Article
Identify RFI Problems in an Intuitive Interface Design by Finding RF Interference Analysis with Altium Radio frequency interference analysis is one important task in high frequency and high-speed PCB design. Interference at radio frequencies can arise due to many simple design errors, but these problems can be easy to spot with the right PCB design tools. When you need to identify areas of a design that can create RFI problems, an automated rules-driven toolset can help. If you’re unclear on what RFI is or how you can spot areas in a design that Read Article
