LED Cube PCB: The Ultimate FAQ Guide


This guide will answer all your questions on LED cube PCB.

Whether you want to learn about material type, specification, features, cost or available designs in the market – you will find all that information right here.

So keep reading to learn more.

What Is An LED Cube PCB?

LED cube PCBs are a three-dimensional cluster of LEDs that can display animations and graphics with the assistance of microprocessors.

Besides, it makes use of the third dimension making it appear in 3D.

With LED cube PCBs, the spacing between LEDs is large for you should see through it.

The spacing resembles a trade-off on how it is easy to see the layers behind and the voxel fidelity.

Also, LED cube PCBs are of low resolution since it takes more time to make them than it is to make LED displays.

For instance, an LED display with 8×8 pixels requires 64 LEDs, but 8x8x8 LED cube PCBs requires 514 LEDs.

Besides, LED cube PCBs can come in any symmetry, be it odd or even.

LED cube PCB


How Does An Led Cube PCB Operate?

These LED PCBs contain several LEDs depending on the design.

Using dedicated input and output ports for each LED is impractical.

This is because you would require microcontrollers that have the same number of IO ports and wires that match the number of LEDs.

Instead, LED cube PCBs use an optical aspect know as persistence of vision [POV].

When the LED flashes quickly, the image of the light will remain on your eye’s retina for a short while after the LED switches off.

By flashing every layer of the LED cube PCB one after the other in quick succession, you get an illusion of a 3-dimensional image.

However, you are instead viewing several series of 2-dimensional images one on top of another.

This effect is known as multiplexing.

What Is The Configuration Of An LED Cube PCB?

Here, we will refer to anodes, cathodes, layers, and columns.

An LED contains two legs, an anode which is the positive leg, and a cathode, the negative leg.

For the LED to emit light, you need to run an electric current from the anode to the cathode.

The LED cube PCB has layers and columns.

Also, you will solder all the cathode legs of each LED within a layer together.

You will also solder all anode legs in a single column together.

Each of the columns in the LED cube PCB connects to controller boards via a separate wire.

Also, you can control every column individually.

LED Cube

LED Cube

Besides, each of the layers in the LED cube PCB has separate wires connecting to the controller board.

Every layer connects to transistors that make the LED cube PCB turn off and on current flow via every layer.

When you switch on the transistor of a single layer, the current from the positive column can only flow in that layer.

The transistor is off for the other layers and the image output on the positive wires will appear on the layer you select.

For the image to show on the next layer, you will turn off the transistor for the layer that was on.

Then, you will alter the image on the anode wires to the image for the upcoming layer.

You will then power on the transistor for the next layer.

This process repeats very fast hence making you see an image on the LED cube PCB.

What Are The LED Cube PCB Sizes And IO Port Requirements?

To operate an LED cube PCB, you require two pairs of IO ports.

One port will source LED in the anode column and the other will sink the cathode layers.

The positive side of the LED cube PCB needs x^2 IO ports when the size of the LED cube PCB is x^3.

For instance, an 8x8x8 LED cube PCB, with x being 8, requires 64 [8^2] IO ports to operate the LED anodes.

The quantity of IO ports increases with the increase in the number of LEDs.

Small LED cube PCBs, such as 3x3x3 or 4x4x4, can operate by connecting cathode layers to the IO pins of microcontrollers.

The current passing through the pins of large LED cube PCBs will be high.

For instance, you require 0.64 Amp for 8x8x8 LED cube PCBs with 10mA on each LED.

Ensure transistors in the layers can handle large amounts of load when you require more than 8x8x8 LED cube PCBs.

What Skills Do You Require When Making An LED Cube PCB?

Here is what you need to understand before making LED cube PCBs:

  • Basic electronics
  • How to solder

What Is The Purpose Of LED Cube PCBs?

LED cube PCB

LED cube PCB

The main function of LED cube PCBs is to serve in the entertainment industries as it is a high-tech display unit.

For instance, the 3D display having several pixels or voxels will show an image of any graphic or animation.

The advancement and design of the LED cube PCB have a lot of potential in the commercial sector.

Also, the LEDs consume less energy, are durable, robust, compact easy to install, environmentally friendly, among other advantages.

How Can You Expand IO Ports In An LED Cube PCB Through Multiplexing?

Here, you will make use of latches or flip-flops, for instance, an 8-bit latch IC known as 74HC574.

This chip contains the pins listed below:

  • 8 inputs and 8 outputs
  • 1 latch pin
  • 1 output enable pin

The latch operated by offering a simple memory and can contain 8 bits of information.

Also, the output pins represent these 8 bits.

What Are Some Alternatives To Expanding The IO Port In LED Cube PCBs?

Another solution entails using a serial-in-parallel out shift register to enable you to achieve, for instance, 64 output lines.

74HC164 is an example of an 8-bit shift register and this chip contains two inputs: data and clock.

How Do You Choose LEDs For An LED Cube PCB?

There are several things you need to consider when choosing LEDs for LED cube PCBs.

These entail the following:

LED Visibility

The LED cube needs to be visible from all angles hence, it is suitable to use diffused LEDs.

Clear LEDs emit most light from the top part of the LED while diffused LEDs emit light equally from all angles.

When you use clear LEDs, they will for a short time, light the LEDs above them as they emit most light in an upward direction.

This will lead to the formation of the ghosting effect.


Large LEDs will produce bright and big pixels.

Depending on the depth of the LED cube PCB layers, you need enough room to see all levels.

For instance, 3mm LEDs enable you to make ‘transparent’ cubes.


You can buy several LED lights for cheap but that may compromise on the quality.

Ensure you purchase high-quality LEDs which will function for long periods.


Square LEDs would look less appealing and you also need to make soldering templates for their square shapes.

Besides, you only require 3mm drill bits when using 3mm round LEDs.


LED cube PCBs rely on multiplexing and persistence of vision [POV] to form images.

When the duty cycle is low, you need the LEDs to emit a bright light enough for you to see.

For instance, you can have a duty cycle where you turn the light on for an eighth of the time.

Leg Length

In some cases, you may end up using the LED legs as the frame for the cube.

The length of the LED legs should equal or surpass the distance between individual LEDs.

How Do You Choose Resistors For LED Cube PCBs?

Here are some things worth considering when selecting resistors for LED cube PCBs:


If the LEDs come with data sheets, an ampere rating is usually indicated in that document.

The two ratings that you can find are mA for a continuous load and another mA for burst loads.

For 8x8x8 LED cube PCBs, the LEDs operate at a 1/8 duty cycle meaning you should refer to burst rating.


The 74HC574 has maximum ratings and in this example, we will consider 8x8x8 LED cube PCBs.

When all LEDs on a single positive column are on, the chip supplies the current 8/8 of the time.

For the output pins, you need to maintain the recommended maximum mA rating as stated in the datasheet.


The transistors need to switch off and on 64 x the mA of the LEDs, when using 8x8x8 LED cube PCBs.

If each LED draws 20mA, you need to switch off and on 1.28 Ampere.



How Can You Create A Template When Building An LED Cube PCB?

For this example, we shall look at how to create the template for 8x8x8 LED cube PCBs.

These are the steps you will follow to create a template:

  • Begin with a piece of plastic or wood bigger than the size of the LED cube PCB.
  • Use drill bits that create holes in which LEDs fit snugly, ensuring it is not too tight or too big as this may cause problems.
  • Using a ruler and an angle iron, draw 8 by 8 grid lines that intersect at 64 points, with the correct LED spacing.
  • With a sharp and pointy material, make indentions on every intersection as they prevent the drill from sliding during the drilling process.
  • Proceed by drilling all the holes on the indentions.
  • Take one LED and try to fit on each hole to ensure it fits snugly, and adjust the hole where necessary.
  • At the middle of each side, make a mark as you will solder a steel wire for every layer thus stiffening the cube.

What Should You Consider When Soldering LED Cube PCBs?

LEDs do not like heat yet you will be soldering close to the LED bodies.

Here are some tips to ensure the soldering process happens accurately with minimal loss:

Soldering Iron Hygiene

Wipe the soldering iron with sponges after every use to ensure it is clean.

Also, the tip of the soldering iron needs to be shiny and clean at all times.

Flux or oxidation can make the soldering tip to be dirty and lose its shininess.

Besides, you can clean the soldering iron during the soldering process as it enhances the heat transfer to the soldering spot.

Soldering Speed

Ensure the soldering process is quick especially when you are soldering close to the LEDs.

Apply a small amount of solder to the soldering tip and touch it to the location you want to solder.

Allow the spot to heat for between 0.5 to 1 second.

A big solder does not make the joint stronger and you should remove the soldering iron once you apply the solder.

Cool Down Time

When you make a mistake, for instance, the wires move before the solder hardens, allow it to cool.

This is because the LED is hot and applying the solder will make it hotter.


Always use a thin solder when soldering the LEDs as it gives you more control and allows you to make clean solder joints.

Also, you can use a 0.5mm gauge solder with flux.


Ensure you test all the LEDs before placing them or after soldering them on the LED cube PCB.

This will save you time as it will be difficult to repair faulty LEDs in the middle of the cube once done.

Is It Important To Test Every LED When Making An LED Cube PCB?

There are instances you may find faulty LEDs and testing allows you to minimize repairs after you are done with soldering.

Besides, you may require surgical tools to repair faulty LEDs at the center of the cube, as it is difficult to reach them.

What Tools Are Necessary For Making LED Cube PCBs?

The following tools are vital for constructing LED cube PCBs:

  • LED tester
  • Wirecutter
  • Soldering stand
  • Solder flux
  • Plier
  • Sponge
  • Solder wick
  • Soldering iron

How Do You Construct An LED Cube?

Here are the steps you should take when making LED cube PCBs:

LED Preparation

Begin by bending the cathode legs of every LED, in the same direction, at 90 degrees.

Begin With Top Rows

Place the LED on the top right side of the template.

Proceed by placing others to the left so that their cathode legs come into contact with the cathode leg of the previous LED.

Rinse and repeat till you reach the left LEDs, then solder all joints.

Solder The Columns

Ensure you have a steady hand when you begin soldering.

Place the second LED from the top and ensure its legs touch the solder joint of the previous stage.

Proceed by placing the LED below it so that the cathode leg comes into contact with the LED on top.

Repeat till you reach the bottom of the cube and then solder all joints.

Add Braces

The layer now resembles a comb and the entire unit is not steady, meaning you will add support structures.

Place bracings near the bottom and middle part of the frame.

Then align a piece of straight wire at a suitable place then solder one of the ends to the layer.

Adjust and make sure it fits and solder the other end.

Proceed by making solder joints for the remaining columns for both braces.

Test All LEDs

Here, ensure the LEDs are functional before you solder them in place.

Remove The Layer

Once you finish soldering the first layer of the LED cube PCB, remove it from the template before proceeding.

Some LEDs will resist when you try to pull them depending on the sizes of the holes for the LEDs.

Avoid grabbing and pulling both sides of the layer as it would damage the whole structure.

To overcome this issue, life individual LEDs in millimeters until you feel no resistance.

Then lift the structure carefully once the LEDs are free from the holes as long as the LEDs are not stuck.


Once you complete that phase, you will repeat the process until you make a full LED cube PCB.

What Are The Available Types Of LED Cube PCBs?

Different types of PCB for LED Cube

Different types of PCBs for LED Cube

These various types include the following:

Rigid LED Cube PCB

This type of PCB cannot fold or twist due to the rigid substrate that offers rigid and strong qualities.

The application of heat or adhesives will assist in holding the various layers together.

Besides, they are available in single, double, or multi-layered designs.

Flex LED Cube PCB

This type of PCB has several parts that are on a flexible substrate that you can bend or fold.

Flex LED cube PCBs can come as single, double, or multi-layered designs.

The materials which you can use to manufacture flex LED cube PCBs are:

  1. Polyester film
  2. Polyamide
  3. Polyether ether ketone

Rigid-flex LED Cube PCB

This type of PCB is a hybrid between flex and rigid LED cube PCB.

During the manufacturing process, the board gets its shape when you flex or curve it.

Besides, the flexible portion acts as the connector for the rigid boards.

Single-sided LED Cube PCB

As one of the common types of PCBs, it contains a single layer of conductive copper above the substrate.

Also, you will solder or place the electrical components on one side of the PCB.

However, due to a single conducting layer, you cannot intersect or overlap conductive layers.

This means it will occupy a lot of space.

Double-sided LED Cube PCB

Here, you will add conducting materials on both sides of the PCB.

Also, the holes within the PCB enable you to connect parts from one side to the other.

Two technologies of connecting circuits on both sides applicable for this type of PCB include:

  1. Surface mount technologyThis method involves placing the components precisely on the surface of the PCB.
  1. Thru-hole technologyHere, you will install the lead parts into holes within the board, then solder them on the opposite side.

Multilayer LED Cube PCB

Visual testing entails checking the physical state of the LED cube PCB for:

  1. Poor mask application
  2. Scratches and dents
  3. Soldering joints
  4. Joint issues, etc.

Automated Optical Inspection [AOI]

Visual testing is effective only to a certain extent as it can miss some flaws hence it is vital to use AOI.

Automated Optical Inspection contains a built-in design that compares to the design of the final LED cube PCB.

Once the system captures an image of the final product, it compares it to the design blueprint and checks for flaws.

X-ray Inspection

The parts of an LED cube PCB may be close to one another when the design is complex.

Automated Optical Inspection may miss flaws in compact PCBs and surface-mounted components.

X-ray inspection allows you to check the solder joints even if the PCB is dense with electrical components.

Since LED cube PCBs containing heavy metals absorb some X-ray, you can check internal parts, connections, and joints.

In-circuit Testing

In this technique, you inspect the position of the parts and how each of them fits on the LED cube PCBs.

Besides, use electrical probes to inspect the LED cube PCB for:

  1. Open ends
  2. Shorts
  3. Resistance
  4. Capacitance, etc.

This method occurs once you complete a thorough inspection of the design and assembly of the LED cube PCB.

Functional Testing

This technique will confirm if the LED cube PCB is working.

For example, it entails checking if it receives power, emits light, meets design parameters, etc.

Besides, you can conduct this test once it is on the clients’ system to ensure it operates well.

Functional testing also involves ensuring the LED cube PCB complies with quality standards.
