We will be elaborately discussing the peelable solder mask to know more about it. This might be helpful for you in many cases.
The Definition Of Peelable Solder Mask
This solder mask is intended to be used only temporarily. In addition to protecting the contact region of the PCB, it is also utilized to protect the thru-holes of PCBs. The protection is for when you assemble the PCBs or implement a surface finish.
Basically, this time, the PCB needs to prevent the solder from flowing to the plated through holes, or to the contacts of the PCBs.
Peelable solder masks are also used in the reflow and wave soldering processes, among other applications. Applying the peelable solder mask may be accomplished using screen printing. The mask is removed after finishing the assembly, surface finish, and soldering.
Peelable Solder Mask On PCB
The peelable mask is easy to use, cost-effective, and easy to remove.
By the way, a peelable solder mask is also known as a temporary mask, removable mask, blue mask, strippable mask, etc.
Characteristics Of Peelable Solder Mask
When it comes to the peelable solder mask, there are a few fundamental characteristics to look for. Following is a list of them:
Peelable Solder Mask Is Easy To Use

What Are The Basic Applications Of Peelable Solder Masks?
Temporary Solder Mask Keeps Thru-Holes Open
The peelable solder mask is used for various needs.
Keeping PCB Thru-Holes Open
Keeping the PCB thru-holes is the most extensive use of the peelable mask. The PCB manufacturers apply the solder mask to make sure that the multiple different areas and vias stay open during assembly and other tasks.
Masking Contact Area Of PCBs
PCB needs conformal coating to protect from environmental and physical damage. During the conformal coating, you must avoid the contact area to coat. Because due to conformal coating, the contact area must be insulated which damages its characteristics.
The peelable solder mask is used to protect the contact area during the conformal coating of PCBs. Also, the solvent-sensitive components are also masked with the temporary solder mask.
Resting Dam For Low Stand-Off Region
During the conformal coating, some surface mount components, and BGA components could go under the coating. This could bring problems to the PCB design. The peelable solder mask is used to make a dam around the SMT and BGA components to avoid flooding the low stand-off regions of boards.
Temporary Protection For Double-Sided PCB Assembly
Double-sided PCBs on one side are ok to assemble and solder with reflow or wave soldering process. But when you flip the board to attach the other side’s components, the newly attached components on the one side could be loosening.
Applying the peelable solder mask helps to keep the components sustained during the other side’s assembly of the double-sided PCBs.
Protection Heat sensitive Components
The temporary solder mask is used during the reflow soldering process of PCBs to protect the temperature-sensitive components.
How To Apply Peelable Solder Mask On PCB?
There are three techniques that you can use for applying the peelable solder mask on PCBs. They are Manual applications, Pneumatic Dispensing, and Stencil Printing.
Peelable solder masks are simple to apply by hand, and they are quite effective. All you have to do is hold the mask bottle correctly and apply the mask to the area where you want it to be applied.
However, it is up to you to ensure that the mask is applied efficiently and effectively based on your previous expertise.
Temporary Solder Mask Manual Application
We have a suggestion for you in terms of holding the bottle. Make sure you hold the peelable mask bottle at a 60-degree angle before applying it. It aids in the placement of the mask by making it more fluid.
When used in the Pneumatic application, the system operates with compressed air or nitrogen as a working medium. The pressurized air pushes the mask out via the dispensing needle, which is located on the side of the mask.
Make use of a low-shear cure mask to offer maximum protection. Because the high cure mask causes curing to be expedited when pressure is applied. When it comes out of the needle, this might get blocked.
The stencil application of the peelable solder mask may be used in the surface-mount assembly process. But make sure you’re only employing this procedure on the PCBs’ flat surfaces.
Additionally, you must ensure that the viscosity is sufficient to regulate the mask. Determine how you’ll clean the mask when you’ve finished using it.
How To Remove Peelable Solder Mask?
It is not necessary to use any special tools in order to remove the peelable solder mask. Actually, you may remove the mask with your hand when it has been cured. A spinning brush or any other hand tools that can catch up with the cured mask may also be used to finish the job.
Remove Peelable Solder Mask Simply With Hand
An aqueous inline system is used to create the peelable mask, which is a basic design element. As a result, check to see whether your peelable solder mask is compatible with your physical filters before using it.
What To Consider To Select The Best Peelable Solder Mask?
To select the best peelable solder mask, there are some facts you should consider.
The peelable mask and the manner of removal are the first things to think about when choosing a peelable mask. Before applying the mask, consider how you will remove it after it has dried.
Check Several Things To Select The Peelable Mask
Choosing your peelable mask for PCB should be done when you are employing solvent clearing. You may use the peelable solder mask in a soldering environment that does not need cleaning. Once the product has been used, it may be removed and cleaned using a solvent.
Make certain that the peelable mask you choose is suitable for use in high-temperature environments. Because your printed circuit boards (PCBs) will be subjected to a significant amount of heat throughout the reflow soldering and assembly process.
You can see the following video for temporary solder mask selection.
Can You Leave The Peelable Solder Mask On Your PCBs?
As the name implies, the peelable solder mask, also known as the temporary solder mask, is only intended for short-term usage. It is used to provide temporary support for the board in order to protect the contacts and holes while the board is being assembled and reflowed.
After you have completed the assembly and finishing of the surface, you should remove the peelable mask.
Peelable Mask Is Recommended To Remove
However, if you want to keep the mask on your boards, you will need to conduct your own functional and reliability tests. Its purpose is to ensure that the physical and performance state of your printed circuit boards is not compromised.
What Are The Types Of Solder Masks?
There are different types of solder masks available besides the peelable mask. They are as follows.
Top And Bottom Side Mask
The components on the printed circuit board are soldered to their respective pins using opening registered masks.
The top conducting side is referred to as top traces, while the bottom conductive side is referred to as bottom traces.
Epoxy Liquid Solder Masks
Polymers, such as epoxy solder masks, are used to make solder masks. This sort of mask is silkscreened onto the printed circuit boards. They are also the most affordable solder masks on the market.
PCBs are printed via silkscreen printing, which makes use of woven mesh. It is necessary in order to support the ink-blocking patterns of the PCBs.
Liquid Photoimageable Solder Masks
Liquid Photoimageable Solder Mask
There are two different types of liquid used to form the Liquid Photoimageable mask. Before putting the mask on the boards, the liquid is combined.
It is one of the most cost-effective and reliable solder masks available. Screen printing, spray applications, curtain coating, and other uses are among them.
Dry Film Photoimageable Solder Masks
Vacuum lamination is required when using the dry film photoimageable mask in conjunction with the dry film photoimageable mask. It is necessary to produce the dry film mask before applying the vacuum laminations.
In addition, openings are ready to be used to create patterns. Following the completion of the design, the components are soldered to the solder pads.
What Are The Types Of Peelable Solder Mask PCB?
Different types of PCBs can use peelable solder masks in terms of needs. The basic types of PCBs are as follows.
Single-sided PCBs are made of a single copper layer. All electrical components are basically soldered on the copper layer of the single-sided PCB. On the other hand, the entire etched traces are shown on the other side of the PCB.
Double-sided PCBs have two conductive copper layers. Each layer contains electrical components. Holes are drilled to connect two layers with each other. Vias are used through the holes to connect the layers.
Multilayer PCBs have at least three conductive copper layers. Like double-sided PCBs, multilayer PCBs also needed to be drilled and connected through vias.
Rigid printed circuit boards are built of rigid PCB materials such as FR4, aluminum, and so on. They are not bendable, twistable, or flexible in any way whatsoever. Rigid printed circuit boards (PCBs) are used in computers, tablets, cellphones, and other electronic devices.
Flexible printed circuit boards are built of flexible PCB materials such as PTFE, polyimide, transparent polyester, and so on. The boards have a supple and twistable feel to them.
Flexible PCBs are used in a variety of industries, including the organic light-emitting diode and flex solar sales.
Why Should I Use Peelable Solder Mask Instead Of Kapton Tape?
In many cases, Kapton tapes are popular because of their reliability and approachability. But, there are things to consider as well.
The main reason that a peelable solder mask is used over Kapton tape is its flexibility. The adhesive on tape can leave residue on the PCBs, which may create issues like wetting facts.
Cleanliness is one of the most important facts in PCB manufacturing. Also, residue will push the manufacturer to spend more time and money to remove them. Summing up the feasibility of the peelable mask, it gets popularity over Kapton or other tapes.
When Should I Remove Peelable Solder Mask From PCBs?
Peelable solder masks are used to prevent printed circuit boards (PCBs) from having molten solder enter the holes and contact regions of the board. Generally speaking, you may wait at least 30 minutes. Also, this could go up to 24 hours.
The reflow weaving, soldering, and assembly should not be done at this point in the procedure. It is necessary to check that the solder mask has been thoroughly cured. If this is not done, there is a danger that the solder mask will be abandoned.
As a result, you should finish the task after the solder mask has been thoroughly cured, and then remove the solder masks once the assembly and soldering processes have been completed.
What Is The Highest Level Of Temperature That Peelable Solder Mask Withstand?
In general, peelable solder masks are designed and manufactured to withstand high temperatures for a shorter period of time. Standard peelable solder masks are intended to resist temperatures of up to 343 degrees Celsius. However, it is possible that the solder mask will be required to endure a lower or higher temperature.
The temperature withstanding the ability of a solder mask is improved as a result of the thickness of the beads. In addition, the type of mask.
What Are The Peelable Solder Mask PCBs Made Of?
PCBs are made of different types of PCB materials. The material selection depends on the requirements and the application of the PCBs. Let’s see the basic PCB materials.
FR4 PCB Material
FR4 is the most widely used printed circuit board material. FR is an abbreviation for flame retardant, which meets the NEMA grade criteria to tolerate high temperatures in certain scenarios.
FR4 is a composite material composed of glass epoxy resin and glass fabric. It is the most cost-effective PCB material available, and it also has excellent mechanical, thermal, and electrical performance characteristics.
By the way, FR4 is mostly utilized for single- and double-sided printed circuit boards (PCBs). Additionally, multilayer PCBs with up to 14 layers stackup are supported.
Polyimide is a flexible PCB material that outperforms FR4 in terms of flexibility. In terms of thermal, electrical, and mechanical performance, it outperforms FR4 in all three categories.
Also more stable in the heat cycle, polyimide is a better choice. The thermal coefficient of expansion of this material is lower than that of steel, which means it has superior thermal resistance ability.
Another well-developed flexible PCB material is Teflon. It outperforms FR and polyimide in every way. It performs better in terms of thermal, electrical, and mechanical properties.
Teflon is utilized in high-speed and high-frequency PCBs. To deal with it, you’ll require specialized talents. Teflon is also more costly than the other two materials.
Aside from that, depending on the uses of the PCBs, aluminum and other flexible materials are also employed in their manufacture for aluminum PCBs, and other PCBs.
Choosing the board material is important. Let’s see how to choose the PCB board material from expert opinion.
What Are The Basic Components Of Peelable Solder Mask PCBs?
PCBs are assembled with several necessary electrical components. Different components function for different needs. The basic components are briefly described below.
Basic PCB Components
- Resistor: A resistor is a device that transfers electrical current in order to create voltage. It works in conjunction with it, dissipating the electric power as heat.
- Transistor: The transistor performs the function of an amplifier. It is responsible for controlling the electrical signals on printed circuit boards.
- Capacitor: The capacitor is a device that stores electric charges. And, when necessary, release them in the direction of the circuit board.
- Inductors: Inductors behave in a similar way as capacitors. They do, however, store electric energy in the form of magnetic energy.
- Diodes: A diode is a device that permits electrical current to flow in one direction while resisting current flow in other directions at the same time.
- Transformers: Electrical energy is transformed from one circuit to another circuit via transformers, which are used to generate electrical power.
- Chips: Microchips are used to perform logical tasks. Microchips are central processing units of PCBs.
What Is The Surface Finish Where The Peelable Solder Mask Is Used?
Surface finish is one of the most important steps in PCB manufacturing. The surface finish is a coating over the exposed copper of PCBs.
It safeguards the exposed metal, especially copper from oxidation. Surface finish is important for the lifespan and performance of PCBs.
Different types of surface finishes are applied based on the type of PCBs and their applications. The common types of surface finishes are briefly described as follows.
In HASL, PCBs are dipped into molten solder. It covers the exposed copper. After cured, the excess solder is removed by hot air knives passing through it.
ENIG Surface Finish
These two are gold-covered surface finishes. In ENIG, nickel is used for coating the copper, and gold covers the nickel.
On the other hand, ENEPIG uses palladium to protect the copper, and immersion gold protects the palladium as well.
Immersion gold surface finishes are more expensive than any other surface finishes.
Immersion Silver (ImAg)
Immersion silver is thin silver plating that covers the copper.
Immersion Tin (ImSn)
Like Immersion Silver, Immersion Tin is used to cover the exposed copper of the PCBs.
Can Peelable Solder Mask Be Used In SMT Reflow Process?
The mask can be used in SMT reflow. But things needed to be explained. Basically, the SMT reflow creates extreme temperatures during the process. So, the solder mask must be able to withstand the high temperature.
If the peelable solder cannot withstand the high temperature, it could be bubbled, charred, and brittle. So, you need to choose the peelable solder mask wisely.
What To Consider To Choose A Peelable Solder Mask PCB Manufacturer?
