Why less mistakes are made with conformal coating masking boots


Conformal coating masking boots reduceΒ mistakes in handling and coating printed circuit boards (PCBs).

The simple reason is that when using tape there is a higher level of skill involved in applying it to the printed circuit board. When placing a boot over a component it is a lot simpler. Therefore, the conformal coating is less likely to leak.

Here are three simple reasons that can save you up to 80% of your costs when using reusable masking boots compared to other conformal coating masking methods:

  1. Masking time is reduced because using boots can be 4-5 times quicker than masking tape.
  2. De-masking time is reduced since it is much quicker to remove boots
  3. Masking boots don’t leak. Therefore, there is less repair due to masking mistakes.

This means you can save a lot of money very quickly when switching to masking boots and reduce the mistakes made during the conformal coating process.

What are conformal coating masking boots and why do they save you money?


Conformal coating application and masking process at SCH Services facility

Reusable conformal coating masking boots are a highly cost-effective alternative to traditional masking tape.

Many components on printed circuit boards must remain uncoated during the conformal coating process. The purpose of masking is to prevent migration of coating materials into connectors, contacts, and defined keep-out areas where coating would cause functional or reliability issues.

Custom-made masking boots provide a major labour-saving advantage during both the masking and de-masking stages of conformal coating. Unlike tape-based masking, these boots are fully reusable and are simply fitted over components such as connectors, plugs, and sockets prior to coating.

Reusable conformal coating masking boots can be designed as simple push-fit caps for standard connectors or as more sophisticated custom geometries for complex or high-density assemblies, as shown in the examples below.

They provide reliable, repeatable protection across all major conformal coating application methods, including:

  • Batch and selective robotic spraying (reducing the need for complex programming)
  • Vertical and horizontal dip coating
  • Vapour deposition processes such as Parylene coating

Three reasons to switch from masking tape to reusable masking boots

Switching from tape-based masking to reusable masking boots can reduce total masking costs by up to 80%:

  1. Faster application – masking boots can be applied 4–5Γ— quicker than masking tape.
  2. Faster removal – de-masking boots is significantly quicker and cleaner than removing tape.
  3. Lower defect risk – masking boots are far less prone to leakage, reducing rework compared to tape.

The result is a rapid reduction in labour cost, improved process consistency, and fewer coating-related defects when compared to traditional masking tape methods.

Need expert advice on masking PCBs before conformal coating?

Effective PCB masking is critical to prevent coating ingress into connectors, test points, keep-out zones and mechanical interfaces. Poor masking choices can lead to coating defects, rework, reliability issues and unnecessary cost.

SCH supports customers with practical masking strategies tailored to your assembly, coating chemistry and production volume β€” from reusable masking boots and tapes to liquid masking systems and process optimisation.

If your assemblies also require preparation before coating, you can learn more about our subcontract PCB cleaning and coating services, or speak directly with our engineers to review your masking and coating requirements.

How do conformal coating masking boots save money in your production process?


Three ways reusable PCB masking solutions reduce coating costs

Switching from disposable tapes to reusable masking solutions can cut conformal coating costs by up to 80%, particularly in medium- to high-volume production.

    1. Faster application. Pre-formed boots are typically 4–5Γ— quicker to apply than manual tape masking,
      reducing operator time per board.
    2. Rapid removal after coating. One-piece removal eliminates the slow peeling, residue cleanup, and inspection
      associated with traditional masking materials.
    3. Lower rework risk. Unlike tape, moulded boots provide consistent sealing around connectors and interfaces,
      reducing coating ingress and costly touch-up or strip-and-recoat cycles.

The result is a more predictable masking process, improved yield, and faster throughputβ€”especially where repeatability matters.

Find out how one company saved 60% of their process costs by changing to custom conformal coating masking boots


Diamond MT, a conformal coating and Parylene coating service provider in the USA, found they saved more than 60% of their current costs by switching to the SCH range of conformal coating masking boots.

Sean Horn, Diamond MT, explains how they did it.

β€œWe had initially wanted to try SCH’s conformal coating masking boots for price savings. However, once we began to work with Lee on our specific masking application, we realised that we could extend the life of our boots over 200%. We switched immediately!

We then realised the importance of working with someone who understands coatings. We will not being going back to our previous supplier.”

Sean Horn, Director, Diamond MT, Parylene and conformal coating subcontract service provider.

So why did Diamond MT switch to our range of masking boots?

When the analysis was completed, it was found pricing for our conformal coating masking boots was lower by 30% compared to their current supplier. This made a significant saving to Diamond MT and immediately a trial production run was started.

What was really interesting was after using them in the first month, Diamond MT found the masking boots lasted twice as long as their original boot from the alternate supplier. This meant that now Diamond MT has halved the volume of boots they order and this has reduced their costs by 60% for the year.

What started as a simple trial led to a huge saving to Diamond MT as a partner with SCH.
