Designing with Shock Management for Avionics PCBs
Of all the electronics application areas, there is one that needs to consider mechanical and thermal shocks during design: avionics. An avionics designed system that is put into production within a satellite, aircraft, or spacecraft can experience strong vibration and mechanical shock during flight, and these systems need to be designed with high reliability in mind. IPC standards, MIL-PRF standards, and other standards specify some design

Customize Your PCB Drill Sizes With Altium Designer
Every PCB will need some holes, vias, slots, and other features that are defined in a PCB layout. These features need to be reflected in fabrication documents, and designers need tools to help them automate this process of creating documentation directly from their designs. It’s easy to keep track of your holes, vias, electrical behavior, and much more in Altium Designer, the industry’s top PCB design application for professional design engineers

Design Your Metal Core PCB in Altium Designer
Most printed circuit boards use a thick FR4 core layer to provide structural stability and interior copper layers for a multilayer PCB. If problems like excessive heat and low thermal dissipation are required in your particular application, you might consider designing with a metal core PCB. You’ll see other advantages like greater structural integrity, as well as a natural EMI shield thanks to the internal metal core. These circuit boards

Designing 5G PCB Devices
The next stage in the evolution of mobile telephony is here with the roll-out of 5G. The designer looking to incorporate functionality to handle 5G signals into their circuits will face some challenging issues. So, what’s so special about 5G? The main change in the jump from 4G to 5G is the frequency band at which signals are transmitted. For 4G, this band covered 0.7 GHz up to 2.5 GHz. For 5G, this new band is an order of magnitude larger, with

What Influences Electrolytic Capacitor Lifespan?
If you speak with a bunch of design engineers, you might quickly believe that the electrolytic capacitor has a particularly dubious reputation. This view certainly hasn’t been helped by the so-called “capacitor plague” that occurred in the first few years of the new millennium. A faulty electrolyte mix used in these types of capacitors led to premature device failures, and quite often, a “bit of a mess” was made to the PCBs on which they were

Estimating and Understanding Thermal Conductivity of PCBs
Your circuit board substrate and copper conductors are the primary factors that determine how heat will move around the board. Your components will generate heat during operation, illustrating the importance of estimating thermal conductivity of a PCB. The thermal properties of your circuit board substrate are one factor that determine temperature rise in your components (particularly junction temperature) and heat flux away from critical

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
