Custom PCB Rulers: The Ultimate FAQ Guide


I know probably, you’re probably looking for the best custom PCB rulers.

Or, you would like to learn more about custom PCB rulers.

A reason this guide will answer all your questions about PCB rulers.

Let’s dive right in.

What Is Custom PCB Ruler?

 PCB Ruler

PCB Ruler

A printed circuit board ruler, or Custom PCB ruler, is a self-contained unit of linked electronic parts utilized in various devices.

It ranges from simple beepers and radios to complex radar and computer systems.

A thin coating of conducting material is placed on the surface of an insulating board known as the substrate to construct the circuits.

Basically, it’s a simple method to keep track of all the different constituents and element sizes on a board.

Their edges are straight, the size is quite accurate, the lines are exquisite, and they frequently contain a wealth of valuable information printed on them.

How Do You Make Custom PCB Ruler?

To make your own Custom PCB ruler, you would need to follow the following steps:

Sketch What You Want Your Ruler To Look Like.

Sketching PCB Ruler

Sketching PCB Ruler

To make it simpler to read, you can utilize a basic design with no numerals.

Now you can open up any program you want and slowly add in as many holes as your ruler demands.

It is much easier to draw each graduation inch by inch, then half-inch by half-inch, quarter by quarter, and so on.

Copy and paste each inch once you’ve completed all of the graduations until your ruler is completely filled.

It’s also a good idea to include a textbox with definitions for each degree. Each graduation is 1/32” in this case.

You may print your design once you’ve finished it, but make sure you do it in reverse; otherwise, your ruler will be bowed.

The PCB Is Prepared, And Transfer Is Applied

After transfer

After transfer

Rough up the copper on the PCB with 220 grit sandpaper to increase your chances of success.

Clean the PCB with electrical contact cleaner or brake cleaner once you’ve achieved a consistent pattern.

After that, try to avoid contacting the copper directly with your fingertips since the oil from your fingers might interfere with the toner’s ability to transfer to the copper.

While cutting off the transfer, set the PCB aside.

Ensure you can attach the sheets to the PCB’s backside to keep it secure while transferring the picture.

Fold the paper around the PCB and tape the backside to keep it tight.

Heating The Iron

Set your iron to the maximum temperature. Apply pressure on the whole PCB for a few minutes after it is hot.

After that, lift the iron and massage the areas on the paper with the iron tip to remove the toner.

This will aid in successful printmaking and a nice transfer.

There’s no actual time restriction here, and as long as the paper doesn’t burn up, you’ll be good to go.

You will get an excellent transfer from the toner after 10 minutes of heating and rubbing every so often.

If the transfer doesn’t proceed as planned, repeat the previous step and print a new transfer sheet.


To make that exchange useful, you must immerse the PCB in an etchant and allow it to resist the transfer.

Use ferric chloride because it gives excellent results.

One of the keys to success with the material is to coat the whole PCB and keep the solution warm when etching.

Construct a basic double boiler out of an old jar and a big measuring cup (both scraps) (also scrap).

Fill the pickle jar halfway with etchant and halfway with PCB. Then, fill the measuring cup with hot water until the pickle jar is full.

Cut To Size And Polish

You may now cut the PCB to the ultimate size of 1 “x3” or whichever size you choose.

This is done after the etching to ensure that the results are as exact as possible in regard to the ruler.

Perform the initial sizing using a belt grinder, then the final size with multiple documents and a little polishing on the sides with 400 grit sandpaper.

Only the copper that was beneath the transfer remains after the etching procedure.

However, the finish is rough and may use some sanding. While polishing to 400 grit or steel wool leaves a great surface.

Polishing with outsole on a cloth buffing wheel leaves the exposed fiberglass as clear as glass.

After you’ve finished polishing, re-spray the PCB with contact cleaner to remove any remaining polish, then buff the copper by hand.

Which Materials Are Ideal For A Custom PCB Ruler?

PCBs are typically a flat laminated amalgamation made from non-conductive substrate materials with copper circuitry entombed internally or on external surfaces.

They can be as simple as one or two layers of copper or as complex as fifty layers or more in high-density implementations.

A glass fiber reinforced epoxy resin compound with a copper foil attached to one or both surfaces is the most popular substrate utilized in printed circuit board rulers.

Custom PCB rulers constructed of paper reinforced phenolic resin with bound copper foil are less costly.

They are frequently utilized in the design of domestic electrical gadgets.

Here is a detailed guide on PCB materials.

What Are The Dimensions Of Custom PCB Ruler?

A Custom PCB ruler with standard thickness has dimensions of about 1” x 6” and includes the most common component packages you’ll find.

For specification, the ruler’s length should be 183mm.

The width should at least be 30mm, the thickness should at least be 1.6 mm, and the weight of the ruler should at least be 17g.

What Are The Main Layers Of Custom PCB Ruler?

There are many different types of printed circuit board rulers available to meet the demands of your design.

From single-sided board rulers to multi-layer rulers and even bendable rulers.

Each of these printed circuit board rulers has a unique number of layers that attribute to their usefulness, making them ideal for various applications.

Regardless of whatever ruler you choose, it must have a fundamental basis upon which it is created, consisting of several elements that are laminated together.

Substrate Layer

The substrate layer of any Custom PCB ruler is often composed of fiberglass, which provides the ruler with its rigidity.

Apart from flexible Custom PCB rulers, constructed on flexible plastic such as Kapton, the bulk of rulers will use this substance as their substrate.

Other materials, like epoxies, can be used to make the substrate Custom PCB ruler layers.

However, they do not have the sturdiness that FR4 (contained in glass fibres) offers for a high-quality ruler.

Copper Layer

The ruler is then laminated with a thin layer of copper foil that is heated.

Because they may rotate between the top and bottom layers through vias, the double-sided rulers enable tighter routing traces.

This may be highly beneficial in designing many electrical devices.

This because the features on one side of the board can be linked to the features on the other using holes punched into it.

Soldermask Layer

Following the application of the copper layer, the solder mask layer is put on top.

This gives the PCB its green color.

It is employed to insulate the copper sheet, preventing any interaction with other parts of the board from disrupting the copper traces.

This layer is also crucial for the assembly process, as it assists the user in soldering the components to the correct locations on the PCB board.

Silk Screen Layer

The silkscreen on the ruler is primarily intended to assist us in better understanding the PCB board.

This also include the operation of various pins or LEDs by putting letters, figures, and characters on the ruler.

Notably, the abovementioned layers are all included in various types of Custom PCB rulers and are critical to the operation of any ruler.

Can You Add Your Information And Logo On A Custom PCB Ruler?

Yes. If you utilize a double-sided PCB, you may include extra information like conversion tables or a second ruler.

On the other hand, the second ruler scale is more challenging since it’s tough to get both copies to line up exactly.

You may also include your name, phone number, and company logo on the Custom PCB ruler.

How Can You Measure Your Wire Thickness Using A Custom PCB ruler?

The ounce (oz) is the most often used unit of measurement for wire thickness on a printed circuit board.

It is the thickness formed when 1 ounce of copper is crushed flat and equally distributed across a one square foot area.

This is equivalent to 1.37 thousandths of an inch (mils).

What Is The Cost Of A Customized Custom PCB ruler?

A Custom PCB ruler with a standard thickness, a weight of 12.07 grams, and dimensions of 6.85 by 1.46 by 0.12inches go for approximately $8.25 each.

However, this price may vary with the customization requests made.

What Are The Uses Of A Custom PCB ruler?

A printed circuit board (PCB) serves as the supporting structure for electrical components.

Most electrical designers require a measuring tool, which may be a collection of all essential functionalities throughout the design process.

A multipurpose Custom PCB ruler can also provide measurements in millimeters and inches. It also incorporates PCB design-related information such as:

  • The number of angle instruments and devices
  • IC Package details, and pin spacing controller table
  • Resistors as well as capacitors SMD package
  • Different electrical components terminal name

It is frequently used as a size reference for hole diameter and width.

PCB traces have far greater accuracy than a ruler would require.

It also offers a typeface size guide, a trace-width schematic, and a pair of AWG-sized drills for gauging wire densities.

How Do You Use A Custom PCB ruler?

A multipurpose Custom PCB ruler includes several features that incorporate important information for PCB designing and layout.

These features exhibit a wide range of functionalities.

The Custom PCB ruler has a “Metric” sign on the left side.

Everything on this side is in metric, beginning with the ruler marks. The ruler is 12” long, with marks that extend just past the 30 points.

Resistor, Ohm’s, And Power Formulas

A few formulas are included under the metric category. Ohm’s Law (V=RI) and the concept of Power (P=VI) are also included.


A large white box may be found on the bottom left of the ruler. It’s an excellent spot to add your name to label your ruler.

You may also use this to insert any detail that isn’t already on the ruler.

Keyboard Shortcuts

Following that, you’ll notice the term ‘Alt’ repeated several times with numbers and marks.

These can be used as a guide to type 330 Ω resistor accurately.

You may input any amount of characters by holding down the alt key and typing the numbers you see.

Light Spectrum

A Custom PCB ruler also provides you with a chart for reference of color wavelengths.


The protractor comes next. The arc is 2mm in diameter; anything less would be too narrow to insert a pen.

Certain pens could still fit, but a pencil, mainly a mechanical pencil, would function perfectly.

There’s also a slight opening at the 90-degree mark. This is also the accurate center of the ruler, which may be helpful.

Metric Prefixes

The metric prefixes, which are the ruler’s main purpose, are marked from 10-15 to 1015 and in multiples of 3.

So, the next time you’re trying to recall whether a ‘pico’ or a ‘nano’ is greater, you may use the Custom PCB ruler.

However, keep in mind that the ruler will not calculate picometers or nanometers but will only assist you in converting.

PCB Trace Widths

On the right, you’ll find marks to assist you in discerning the difference between a 0.1mm line and a 2.0mm line.

Recognizing what the thickness of your traces looks like is one of the factors that may be valuable when designing PCBs.

There is also an mm to mil converter available.

What Are The Ideal Features Of A Custom PCB Ruler?

A Custom PCB ruler engineering measurement instrument must offer the following features to aid in the design and development of PCBs and Circuits.

  • Custom PCB ruler 12 inch with indications down to 0.05” or 1/32” Custom PCB ruler 30.48 cm with marks down to 0.1mm
  • Electrical formulas.
  • Alternate Keyboard Codes
  • Wavelengths of Color
  • Metric Conversions
  • Protractor
  • Metric Prefix Overview Chart
  • Morse code Transistor Schematics
  • The Roman Numerals
  • Summary of Fractions
  • Wire Gauge Diagram
  • A size of 12” x 1.5”
  • A Tap and Drill Diagram

The scale is constructed of PCB materials.

All printing on the scale is done using copper etching and often has gold plating for a high-end atmosphere, high durability, and abrasion resistance.

The hole’s wall is copper-clad and 25 microns thick.

This feature improves the ruler’s resilience by increasing its capacity to withstand z-axis expansion.

It is important not to blow through the hole as this may result in inaccuracy issues due to assembling and design flaws.

A very dependable printed circuit board ruler may be obtained if no soldering repairs are performed and no break line repairs are performed.

Maintenance is not required for solder-free repairs.

It also produces a no-error condition, making the Custom PCB ruler nearly flawless in terms of functionality.

Because there are no line breaks to fix, the potential of inaccuracy is nil.

As a result, rulers that do not require soldering are regarded as very dependable.

Even though there are no relevant rules describing the thickness of solder resistance, it should be tolerant enough to maintain electrical insulation flawlessly.

A thick solder resistance layer minimizes the danger of flaking and makes it more resistant to mechanical stress.

If the solder resistance layer is not sufficiently thick, it may peel off, subjecting the Custom PCB ruler to caustic compounds.

As a result, the insulation is inadequate.

Consequently, a high-reliability Custom PCB ruler features an extremely thick soldering resistant layer.

Why Should You Get Yourself A Custom PCB Ruler?

The printed circuit board ruler is an essential tool in the design of advanced electronic equipment.

An excellent PCB design can assist in reducing the possibility of mistakes as well as short circuits.

PCBs play an essential part in today’s world, since technology advances regularly.

Because they are utilized in the design of nearly every electronic device, these Custom PCB rulers form the cornerstone of electronic devices.

Do Custom PCB rulers Have Components?

Yes. Like those on circuit boards, its connections are gently wrapped in copper and enveloped by a swampy-green colored fiberglass epoxy resin.

Printed circuit board rulers are often a flat-coated composite.

You can construct them from non-conductive substrate components with layers of copper circuitry embedded within or on the exterior surfaces.

They can be as basic as one or two sheets of copper, or they might have many layers in high-density application areas for design.

A typical printed circuit board has six fundamental components:

  • Prepreg
  • Copper foil
  • Copper foil
  • Soldermask
  • Nomenclature
  • Final finish

Is Custom PCB Ruler Bendable?

 Bendable PCB Ruler

Bendable PCB Ruler

The underlying idea for bending, shaping, and flexing is the same for all Custom PCB rulers.

However, the structure of the Custom PCB ruler and the components used will limit how a ruler may be bent, shaped, or flexed.

Normally, woven glass fiber reinforced Custom PCB rulers cannot be consistently bent, shaped, or twisted.

When maximum flexibility and dependability are required, flexible printed circuit board rulers are commonly utilized.

Flexible design is necessary if a ruler needs to be bent during PCB assembly.

They’re also great for when flexing and warping are unavoidable.

Is Gold Plated Custom Ruler Better Than Standard Custom PCB Rulers?

The gold in gold-plated Custom PCB rulers preserve the nickel while it is stored and provide the reduced contact sensitivity necessary for thin gold deposits.

Because gold is one of the most malleable metals, it is simple to add a very thin layer on the surface.

The fact that only a thin coating of gold is required contributes to the low cost.

It also increases its longevity by providing excellent resistance to regular wear and tear.

When compared to standard rulers, gold-plated Custom PCB rulers have a longer contact lifespan.

Is There Standard Dimensions Can For Custom PCB Ruler?

Yes. Custom PCB rulers should have a recommended measurement range of 25cm/10.23in, 15cm/6.3inch, and 2cm/7.81inch for precision and high reliability.

The ruler’s length should be 183mm; its breadth should be at least 30mm, its thickness should be 1.6 mm; and its weight should be 17g.

Can You Repair Custom PCB ruler?


The most common cause for the repair of a Custom PCB ruler is physical damage.

Aside from physical damage, the most prevalent cause of printed circuit board ruler failures is defective features.

If there is no physical damage yet a PCB board fails to function, you can nearly always blame it on one of the ruler’s characteristics.

The feature may be anything from a protractor to equations or charts in and of itself.

If the features are a problem, it may be necessary to replace them altogether.

However, it is not usually the characteristics themselves that are the issue.

The ruler may have degraded to the point that it is no longer functional owing to age, scorching, and repeated repairs.

Most of the time, it is preferable to leave the repair and remanufacturing of defective Custom PCB ruler features to experts.

There are instruments and equipment available to assess the accuracy of a ruler’s features.

Simply looking at the ruler may often reveal faults, such as their print font appearing degraded or unreadable.

Heat may be required to fix a defective Custom PCB ruler.

Typically, a heat gun is used for soldering, and thorough testing is performed.
