Altium Video Tutorial – PCB Layout

Altium Video Tutorial – PCB Layout

This is the third post in our Altium Designer PCB design video tutorial series.  The first video showed you the basics of creating a PCB project in Altium.  The second demonstrated how to work with schematics.  In this video we’ll be building on the schematics we drew up last time and create a PCB layout for our design.   Register for our Complete Altium Video Tutorial Series   Overview Importing PCB footprints into your layout Working with PCB design rules Placing...

Altium Video Tutorial – Schematic Capture

Altium Video Tutorial – Schematic Capture

This is the second post in our Altium Designer PCB design video tutorial series.  In the first video, we created the files necessary for our PCB project.  Building on what we created in that video, we will now enter the schematics for a simple voltage break out board.  This board takes an input voltage (5V nominal) and outputs 3.3V and 1.8V.     Register for our Complete Altium Video Tutorial Series   Overview Installing Libraries Inserting Components in a Schematic Using Net...

Guard Traces

Guard Traces

We’ve examined a couple mechanisms for crosstalk, so what options do we have to reduce this undesirable effect?  Well, utilizing guard traces is commonly considered a “best practice” by many PCB designers for reducing crosstalk.  Guard traces are grounded copper lines running parallel to sensitive traces on a PCB.    The figure below shows a guard trace inserted between two signal traces on a PCB.     Now that you know what they are, should you start sprinkling...

Standard 4- and 6-Layer PCB Stackups

Standard 4- and 6-Layer PCB Stackups

Requirements for every PCB are unique, so it’s a bit of a misnomer to call the stackups presented below “standard.”  If for instance, you have a requirement that the PCB must pass FCC compliance testing while operating outside a shielded enclosure, perhaps these stackups aren’t for you.  With that said, these stackups are a great starting point and as-is, will suit most designer’s needs.   4 Layer Stackup The classic 4-layer PCB stackup includes two...

Mutual Inductance

Mutual Inductance

In addition to mutual capacitance, there is another, often more important mechanism for circuit interaction in high speed digital design – mutual inductance.  Mutual inductance is present wherever there are two loops of current.  These current loops produce magnetic fields which interact with one another proportionally to the rate of change of current within the loop.     Mutual inductance is the proportionality factor by which a voltage is induced in a circuit in response to...
