Quadra Solutions’ guide to PCB track length matching in high-speed design

To maximise the performance of a circuit design, the implementation of track length matching is key. In any circuit design, an electronic signal takes a certain amount of time to travel along the conductor to reach its end destination. It is crucial to identify the sections of a printed circuit board (PCB) design that requires length matching to guarantee that the signals arrive with accurate timing.

 

Track length matching is normally thought of as in pairs, but it also applies to buses with single-ended signals and differentially-driven buses. As CPU peripherals and other digital systems require faster-operating speeds, the propagation delays in a high-speed system, places tight tolerances on the allowed track length in a conductor carrying digital signals.

This article explores Quadra’s best practices for applying track length matching.

PCB track widths

So, what is Track length matching?

As the name suggests this is the laying out of a design that matches the lengths of two or more PCB tracks, also known as traces. These groups could be one of the following:

  • Single-ended tracks routed in parallel.
  • Differential pairs.
  • Multiple differential pairs in parallel.
  • Clock signals in either single-ended or differential pairs in parallel.

 

PCB tracks carrying digital signals do not necessarily need to be perfectly length matched. With copper surface layer tracking there will always be an amount of jitter on the rising edge, preventing signals routed in parallel to be perfectly length matched. The end goal is to reduce the length or timing mismatch below limiting values. The allowed length mismatch and timing mismatch are related to the signal velocity.

How do you know what track length is optimum?

Component datasheets, signalling standards and interface standards are key. There is so much standardisation these days that most high-speed components use one of the many signalling standards. Manufacturers should always have impedance and routing specifications available.

A length mismatch can also be converted to a timing mismatch using signal velocity, although extreme care must be exercised when selecting the velocity of a digital signal. Modern digital signals, generally run with edge rates much less than 1 ns, will have bandwidths reaching into the high GHz, and will only tolerate very small mismatches. Dispersion in the PCB substrate causes the signal velocity to vary with frequency. For example, FR4 exhibits normal dispersion below ~1 GHz, so lower frequencies will arrive at the receiver earlier than higher frequencies.

 

Clock Signals

Using system clocks to trigger every device in a chain of components is extremely difficult in large designs. This is, in part, due to the fact that each integrated circuit has different logic gate delays and rise timing. Typically, modern digital components use source synchronisation or embedded clocks. For embedded clocks signals it is best practice to route a track alongside the parallel data track. The clock tracks also need to be length matched to other data tracks.

 

Track length matching to prevent skew on parallel data buses

pcb tracks

Skew simply refers to a timing mismatch between the rising edges of two or more digital signals in a parallel bus. The signal propagating on the shortest trace will arrive earliest, triggering a downstream gate before the other signals on the bus. eCADSTAR allows you to define buses and differential pairs at the schematic stage, enabling you to enforce track length matching your layout which will keep any skew within tolerable limits.

 

Length matching in multiple single-ended nets is straightforward. Adding tuning structures to all tracks on the bus ensures they are the same end length.

If you have multiple differential pairs carrying parallel data, each differential pair must be matched, and the pairs then need to be matched to each other.

 

What About Analogue Differential Signals?

Analogue signals can also be routed as differential pairs; however, it is less common even at very high frequencies. Some manufacturers offer differential op-amps for high GHz bandwidth allowing for easier routing of analogue signals around a board.

Analogue differential signals require accurate length matching, just like digital differential signals. The difference is that analogue differential signals resemble 3-phase AC wiring, where an adjacent analogue ground plane is used as a reference for both ends of the pair. While digital signals do not explicitly need a ground plane, placing a ground plane adjacent to the digital differential pair is beneficial for the reasons outlined above.

Effective PCB design | How to ensure your PCB Trace Widths are Effective

Sarah Santangelli takes us through the importance of Trace Widths and what they mean for your PCB design.

What is Trace Width?

Trace widths

Trace width is an important design factor in PCB design. PCB trace could be analog, digital or power, from one junction to another.

The junction can be the pin of a component, a branch off of a larger trace or plane, or an empty pad or test-point intended for probing. Trace widths are often measured in mils, or thousands of an inch. A standard trace width for an ordinary signal (no special requirements) may be in the 7-12 mil range and be as long as a few inches, but there are many things that should be considered when defining the width and length of a trace.

Efficient Trace Width

To ensure effective operation in transmitting signal and power the importance of PCB Trace Width and resistance is crucial. So, what steps do you need to take?

Determine the standard track width to be used

  • It is important to balance the standard track size to be used within the design. Too narrow and too close means there is a higher chance of it shorting. If they are too wide and far apart, it can restrict the number of tracks in a given area and this may force the use of additional planes in the boards to ensure the PCB design can be routed. It is a balancing act that needs to be right.

 

Consider track size for lines carrying current

  • The thin tracks used in today’s printed circuit boards can only carry a limited current. Consideration needs to be given to the size of the trace for any that carry power rails rather than low level signals. The table below gives some track widths or a 10degree C temperature rise for different thickness copper boards.

 

RECOMMENDED MAXIMUM CURRENT FOR PCB TRACE
CURRENT
(AMPS)
WIDTH FOR 1 OZ BOARD
(THOUS)
WIDTH FOR 2 OZ BOARD
(THOUS)
1105
22015
35025

Fix the printed circuit board pad to hole ratio and size

  • At the beginning of the PCB design it will be necessary to determine the pad and hole dimensions. Typically a ratio of about 1.8: 1 (pad : hole) is used, although sometimes a pad 0..5 mm larger than the hole is used as the measure. This allows for hole drilling tolerances, etc. The manufacturer of the bare PCB will be able to advise on the standards that are required for their process. The ratio becomes more important as the size of the pads and holes reduces, and it is particularly important for via holes.

Determine PCB pad shapes

  • Component libraries associated with PCB CAD systems will have libraries for the schematic and PCB footprints for the different components. However these may vary according to the manufacturing process. Typically they need to be large for wave soldering than for infra-red reflow soldering. Thus the manufacturing process needs to be determined before the design starts so that the optimum pad sizes can be chosen and used on the PCB CAD system and hence on the printed circuit board itself.

5 Reasons to Manufacture your PCB’s with Quadra

There are many good reasons to outsource the manufacture of your PCB designs but here are the top 5.

1. Cost-efficient PCB’s

Operating in-house manufacturing facilities is expensive. Set-up and day-to-day operation require significant investment and outlay, limiting capacity for spending in other areas and the time spent making PCB prototypes, disrupting normal business can cost you and your business.

2. Dedicated product assembly expertise

By using contract product assembly services, you are assured access to dedicated expertise. We have the skills and access to all the relevant technologies and supplier to make the process as seamless as possible for you.

3. When time is of the essence

Does your business have the in-house manufacturing capability to cope with the potential peaks and troughs of demand? Cost efficiency and reliability are key. To stay competitive you need the resources to ensure that market needs are met quickly. We can help with that.

4. Quality Manufacturing

Manufacture and assembly work is carried out in strict accordance with national and international standards and in today’s increasingly global marketplace, where companies must comply with a growing number of these standards.

5. Better lead times

Order size and frequency can fluctuate; working with a contract electronics manufacturer is a cost-efficient way to manage this fluctuation in market demand. A contract product assembly company has the capacity and resources to deal easily with spikes in demand. This guarantees that you always receive exactly what you need when you need it.

eCADSTAR Bytesize Tutorial – Advanced Variance

Transcript

If you’ve used CADSTAR’s variance before, it’s a very powerful tool. eCADSTAR is capable of variance as well, more advanced variants.

But at the very basic level, you can define a device as not being fitted, so if I click on this resistors for example and I change the properties, here you can see I’ve got fitted and I can say NO. And you can see it has changed the colour of the trace because it superfluous now, there’s no connection there.

Obviously, it will still exist on the PCB it’s just highlighting it for us. You don’t have to have it dashed and coloured, this is entirely up to you. Completely Configurable

Frequently Asked PCB Design Questions

In today’s blog we answer the most frequently asked PCB design questions

1. Whats is PCB Design?

Printed circuit board (PCBdesign brings your electronic circuits to life in the physical form. Using layout software, the PCB design process combines component placement and routing to define electrical connectivity on a manufactured circuit board.

2. What is a PCB made from?

A printed circuit board (PCB) is a thin board made from fiberglass, composite epoxy, or other laminate materials. PCBs are found in various electrical and electronic components such as beepers, radios, radars, computer systems, etc. Different types of PCBs are used based on the applications.

printed circuit board (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate.

3. Which materials are used for PCBs?

Printed circuit boards (PCBs) are usually a flat laminated composite made from non-conductive substrate materials with layers of copper circuitry buried internally or on the external surfaces. They can be as simple as one or two layers of copper, or in high density applications they can have fifty layers or more.

4. Why is Copper used in PCB?

The most common element used to make traces is copper. Why is copper such a popular choice in the PCB industry? The number one benefit of copper is that it is highly conductive. This means that it can easily transmit signals without losing electricity along the way.

5. What data is required for a PCB design quote?

We often only need the basics of a design to begin the process of PCB design. At Quadra we’re happy to accept any form of input. Some of our customers provide completed CAD generated schematics, but we can work with a hand-drawn sketch if required.

6. Which PCB/CAD tools does Quadra use?

Cadence Allegro: We have extensive experience with the Cadence Allegro tool suite

Mentor Graphics Expedition, Power PCB (PADS) and Board Station:

Altium: Now supported with Altium 365 making feedback and design changes easier.

So Samacsys have sourced this footprint for us and they aligned it. The alignment process is really easy. If there isn’t a 3d model, usually the manufacturer doesn’t have one, occasionally Samacsys might overlook one, always worth checking the manufacturer, if they don’t have a 3D model, then a good resource is 3dcontentcentral.com. There’s a lot of content on there. You have to do your due diligence but it’s a good resource. Part acceptance, this is useful.

If you are using the ECIP ( Electronic Component Information Partner) downloading parts from the internet, it might be a good idea to say unapproved and then add a reason. Then at various stages of your design, that will pop up on screen. Any devices that are unapproved for example if you are pushing your schematic out to a PCB or generating Gerbers, a little pop up on screen will say these parts are still unapproved. Do you wish to continue? yes or no? It’s not restrictive you can carry on. It’s just making you aware that some devices are unapproved.

eCADSTAR – Intelligent PDF

Hello and welcome to this demonstration of eCADSTARs Intelligent PDF. In this video we will output an intelligent PDF from an 8 page schematic using eCADSTAR. This feature is available from eCADSTAR’s 2020 release.

Here in my design tree you will see I have an 8 page schematic open containing lots of information to process into a PDF.

I go to File>Print and eCadstar’s print dialogue appears.

In the output box select PDF to enable eCADSTARs Intelligent PDF dialogue.

There are three tabs full of options enabling you to customize what information from your design you would like to output.

The first tab has basic settings and options. We need to select PDF and specify a library path and name. This is also where you can specify the size, orientation and scale of the output and there’s additionally checkboxes here for options for outputting not fitted components, and not connected pins and net nodes.

In the PDF settings tab in the annotation settings we can select to output hierarchical blocks and this is where you can specify what properties you would like to output. There are lots of options to choose from allowing you to really customize the information displayed on the intelligent PDF. You can specify what attributes you want to display when you click on a component, pin or net, allowing you to choose how much detail you would like to display.

The bookmark section allows you to output a navigation panel in the PDF which when selected will center and zoom the object. You can also choose to compress the file size.

In the target data tab select what pages of your schematic you would like to output. I am going to select them all and let’s see how eCADSTAR handles processing all of this information.

I now navigate to the file path I have specified and open the intelligent PDF I have just created. You will notice eCADSTAR has compiled all the pages into one document. On the left-hand side, you will notice the Bookmark navigation panel with headers to each page, component, component pin and nets. When I click on a reference designator you can see how the PDF has now focused in on that component, we can take this further and focus in on each individual pin. You can also navigate through your net list.

When I click on the component, component pin, or net you can see the attributes I have chosen are displayed.

Thank you for watching and I hope you’ve enjoyed this insight into eCADSTAR’s Intelligent PDF.
