Green PCB: The Ultimate FAQ Guide

Are you wondering about protecting your PCB circuits from short circuits?

Or are you planning to remove the soldering errors from the circuits of your sensitive devices?

Don’t worry! Green PCB can be your best pick in both of the above cases since it is most common in circuits.

That is why we have collected every relevant question to this common PCB in the guide below.

Let’s get started without any further ado.

What is Green PCB?

A green PCB is a type of printed board circuit that is not adequately green on all its surfaces but exhibits a green color due to the solder mask.

The solder mask, also known as the outer covering made up of resin to resist the solder or oil, is usually green in color, thereby giving prominent green color to the printed board circuit.

This green-colored resin in the majority of the PCBs is hardened with the help of many other pigments, which are applied to the silkscreen fashion board of the circuit.

The significant green color solder mask on the Green PCB plays the leading role in preventing short circuits in the PCBs.

In addition to this, the soldering errors have also been significantly reduced with green-colored PCBs in the circuits.

The prominent appearance of the printed board circuit in different electrical circuits is also due to the green-colored resin embedded in it.

However, not all printed board circuits are green. The manufacturers can use any color for the resin by mixing it with different types of colored pigments.

What is the Purpose of Green PCB?

The primary purpose of the Green PCB is to support the printed board circuit without damaging or oxidizing the copper installed on the board.

Besides this, it also plays an essential role in connecting all the electric components with the help of conductive pathways.

Both layers of copper on the printed board circuit are soldered green for reducing the extent of oxidation during working.

Another essential purpose for which green printed board circuit is used in the electric devices is to prevent the short circuits and the excessive waste of electricity.

They are also used to decrease the soldering errors in the printed board circuits. These sheets are laminated on copper as a non-conductive substrate.

The non-conductive substrate and the solder mask play the leading role in supporting the circuit boards in all sensitive electric devices.

The green solder mask done on the copper layers of PCB is famous for protecting these copper sheets from corrosion and moisture.

The soldering rework can also be done with the help of a green covering on the copper sheets of the printed board circuit.

Why Are PCBs Green?

Some of the common reasons due to which printed board circuits are green in color are listed as under:

  • Material Used in Construction

One of the common reasons for the green color of printed board circuits is the use of particular materials in their construction.

These materials include the glass epoxy that is green in color to make the solder mask for copper sheets. The majority of the manufacturers choose a green color to cover the copper sheets with the solder mask.

Fiberglass boards are also used in the construction of green PCBs. They are also grey, thereby giving prominent green color to the printed board circuits.

  • Contrast Of the Text

Many manufacturers prefer the green color of the PCBs because it doesn’t cause any problem to the observer’s eye.

It is pretty easy to observe every part of the printed board circuit because of the green-colored resins.

Moreover, the manufacturers consider it cost-effective to produce the printed board circuits with green-colored resins and solder masks.

  • Exposure Rate of Solder Mask

The green color in the PCBs is substantially due to the solder mask present on the copper sheets. This solder mask has increased the exposure of PCBs.

When you install different solder masks with varying colors, there are many potential changes for the requirement of a higher solder mask.

But in the green soldered PCBs, you have to achieve a tight tolerance on the PCB design, thereby reducing the need for exposure.

  • Take a Layout of the Print Board Circuit

The first step in manufacturing green masks in the PCBs is to make a layout of the PCB design on the butter paper.

Make sure to take a negative layout image of the soldering pad. The soldering pad should be white, and the surrounding material should be black.

  • Preparation of the Silkscreen for Painting

Once you’re done with the layout of the green PCBs, it’s time to prepare the silkscreen for the screen printing process. For doing so, make sure to purchase the highest quality silkscreen.

Carry out the exposure method on the silkscreen by using the photo coat emulsions. After this, mix the photo coat thing with the potassium dichromate. Apply the mixture on the upper layer of the screen and let it dry.

  • Print the Circuit

After complete drying of the solution on the silkscreen, it’s time to print the circuit with the help of dried silkscreen. Make sure to trace the layout of the circuit with high-quality ink.

You can use special tools for marking the exact size of the PCB components on the circuit. After that, spread the ink on the circuit layout and allow it to dry.

  • Etching Process of PCB

The next step after printing the PCB circuit is to etch it. Try to etch the printed board circuit with the help of ferric chloride solution.

This method is used to remove the excessive amount of copper on the circuit board. Stop etching the PCB once all extra copper is removed.

  • Application of Green Soldering Mask on PCB

The last and essential step is the application of the green PCB. In this step, it is required to arrange the screen with the soldering pad of the printed board circuit.

Apply a small quantity of hardener along with a small amount of photo imageable ink. Once you’ve spread the ink, try to spread the mixture all over PCB and allow it to dry. After complete drying, make sure to carry out a dip soldering.

You can also contact PCBMay to get the highest quality of green PCB soldering masks.
