Parylene vs Traditional Coatings: Which is Right for You?

October 2, 2025 Parylene

When it comes to protecting sensitive electronics, medical devices, and mission-critical components, the choice of coating can define long-term performance. Two common options are Parylene coating and traditional conformal coatings such as acrylics, silicones, and urethanes. Each offers unique benefits — but which is right for your application?

For an overview of vapour-deposited protection and where it fits within modern electronics manufacturing, see our Parylene coating solutions.

What Makes Parylene Different?

Parylene is applied using a vapour deposition process, producing a pinhole-free, highly uniform film that coats every exposed surface — including hidden spaces and complex geometries.

This process helps deliver:

Exceptional moisture barrier performance
Ultra-thin yet durable protection
Strong resistance to chemicals, solvents, and temperature extremes

Because it forms a truly conformal layer, Parylene is often selected where reliability cannot be compromised.

Our Parylene coating services are used where uniform coverage, low thickness, and high reliability are critical.

Where Traditional Conformal Coatings Excel

Traditional conformal coatings are typically applied by brushing, spraying, or dipping. They remain highly effective in many environments and offer practical advantages such as:

Faster application and curing (process dependent)
Lower cost compared to Parylene (in many cases)
Easier rework and repair during production

For applications where cost sensitivity or rapid turnaround is key, traditional coatings can be the most commercially sensible option.

For applications where cost, speed, or rework access are priorities, our liquid conformal coating solutions remain a highly effective option.

Making the Right Choice

The right choice depends on your environment and performance requirements. If your device must endure harsh conditions or complex 3D coverage requirements, Parylene coating can provide unmatched protection. For less demanding applications, traditional conformal coatings may strike the best balance between performance, reworkability, and budget.

The right choice depends on environment, geometry, and compliance requirements, which is why many manufacturers engage our coating services for application-specific guidance and discuss the options.

SCH Services Ltd: Your Coating Partner

At SCH Services Ltd, we provide both Parylene and liquid conformal coating solutions — helping you select the right option for your project. Whether you need high-performance protection or cost-effective coverage, our expertise ensures your product is protected for the long term.

Conformal coating masking solutions including reusable boots, high-temperature masking tapes, dots, and custom shapes for protecting PCBs during coating and Parylene processes

From Bottleneck to Breakthrough: How Custom Masking Shapes Transform Conformal Coating Production

October 1, 2025 Masking

In modern electronics and high-reliability assemblies, one of the most overlooked yet critical steps is masking—protecting areas that must remain coating-free during the conformal coating process. Done poorly, masking becomes a bottleneck: misalignment, rework, and delays can cripple throughput. But with custom masking shapes for conformal coating, you can turn that bottleneck into a breakthrough.

Explore our range of custom masking shapes for conformal coating designed to speed setup, improve consistency, and boost production yield.

The Masking Challenge

When applying conformal coatings—or advanced materials like Parylene—pads, connectors, keep-out zones, and sensitive features must be protected precisely. Traditional manual cutting of tape is slow, inconsistent, and often unreliable.

The result?

Masking residue left behind
Shrinkage or degradation under solvents
De-wetting caused by silicone contamination
Tape lifting or coating bleed into protected areas

These issues reduce yield, increase rework, and slow down production.

For a full breakdown of masking options and where each is best used, see Conformal Coating Masking: Methods & Materials.

The Advantage of Custom Masking Shapes

At SCH Services Ltd, we provide custom masking shapes designed specifically for conformal coating processes—including the same materials we use in our own production services. That means the shapes we supply are proven daily for accuracy, consistency, and clean removal.

Benefits of custom shapes include:

Residue-free removal with no damage to components
Solvent and chemical resistance for demanding environments
Silicone-free materials to reduce contamination and coating defects
Clean, reliable adhesion that helps prevent lifting and bleed
Ready-to-use sheets for fast application and reduced operator time

Because we rely on these shapes daily in our own conformal coating services, we know firsthand how they improve throughput, reduce defects, and remove bottlenecks.

For standard formats or fast turnaround requirements, custom masking dot and shape sheets can also be ordered directly via our online shop. Order custom masking dot and shape sheets online.

From Bottleneck to Breakthrough

Standardising masking with custom masking shapes for conformal coating improves speed and repeatability—while reducing operator variation.

CHALLENGE	MANUAL MASKING	CUSTOM MASKING SHAPES
Cutting & prep time	High	Minimal – peel & place
Consistency	Operator dependent	Uniform every time
Risk of rework/defects	High	Low
Cycle efficiency	Slow	Streamlined
Yield loss	Frequent	Reduced

By reducing cutting time and improving repeatability, masking becomes faster, cleaner, and more reliable—supporting higher yield and smoother production flow.

SCH Services Ltd: Proven in Our Own Services

Unlike suppliers who only sell materials, SCH Services Ltd actively uses these masking shapes in our own conformal and Parylene coating services. Customers benefit from the same speed, precision, and clean demasking performance we demand for our own clients.

When reliability matters, masking isn’t a bottleneck—it’s a breakthrough.

If you’re ready to standardise masking in your production, learn more about custom masking shapes for conformal coating and how they can reduce defects and cycle time.

If you already know your masking requirements, you can order custom masking dot and shape sheets directly from our shop, or contact us for fully bespoke designs.

Static control and electrostatic discharge protection in industrial electronics manufacturing

Why Static Control Matters More Than Ever in Modern Industries

September 30, 2025 ProShieldESD

In today’s high-tech manufacturing and logistics environments, static electricity is far more than an occasional nuisance — it represents a significant commercial, quality, and safety risk. Across electronics manufacturing, medical devices, automotive systems, aerospace, and logistics, uncontrolled electrostatic discharge (ESD) can damage sensitive components, disrupt production, and compromise long-term reliability.

The Hidden Risk of Electrostatic Discharge (ESD)

Electrostatic discharge occurs when two objects with different electrical charges come into contact or close proximity, allowing charge to transfer rapidly. While a human may only feel a static shock at around 3,000 volts, modern electronic components can be permanently damaged by discharges as low as 30 volts. As electronics continue to shrink and performance densities increase, tolerance to ESD continues to decline.

This means effective static control is no longer optional — it is a fundamental requirement for modern manufacturing and handling environments.

Industry Impact: Where ESD Causes the Most Damage

Electronics Manufacturing – ESD can cause latent damage to semiconductors, leading to early-life failures, reduced yield, and costly field returns.
Automotive & Aerospace – Modern vehicles and aircraft rely heavily on complex electronics; ESD-related failures can impact safety-critical systems.
Medical Devices – Reliability is essential. ESD damage in medical electronics can compromise performance and patient safety.
Logistics & Packaging – Poor static control increases the risk of component damage during storage and transport and can introduce ignition hazards in sensitive environments.

Why Static Control Is Becoming More Critical

Component Miniaturisation – Smaller geometries and thinner insulating layers increase ESD sensitivity.
Extended Global Supply Chains – ESD damage can occur at any stage, from manufacture through shipping and final assembly.
Compliance and Quality Expectations – Standards and customer requirements increasingly demand robust ESD controls.
Waste Reduction and Sustainability – Preventing scrap and rework lowers environmental impact and total cost.

Modern Approaches to Static Control

Traditional static control methods — such as temporary sprays or heavily filled conductive paints — often degrade over time, require frequent reapplication, or introduce contamination risks. Modern ESD strategies focus on permanent, homogeneous dissipation methods that provide stable performance throughout the product lifecycle.

Innovative conductive polymer technologies, such as those used in ProShieldESD, enable uniform static dissipation across a wide range of substrates including plastics, foams, paper, cardboard, packaging, and flooring. These solutions provide long-term protection without the drawbacks associated with carbon or metal-filled systems.

Static Control as a Long-Term Strategy

Effective static control is not a one-off fix — it is a strategic decision that supports quality, safety, and operational efficiency. Organisations that invest in robust ESD protection reduce downtime, minimise losses, and protect their reputation for reliability.

For businesses operating in high-reliability industries, controlling static electricity is not simply good practice — it is mission-critical.

Parylene coating providing invisible protection for electronic components against moisture and environmental damage

The Hidden Protector: How Parylene Safeguards What You Don’t See

September 29, 2025 Parylene

When it comes to protecting modern electronics and critical components, the greatest threats are often the ones you cannot see. Microscopic cracks, invisible moisture, and environmental contaminants all pose silent risks to performance and long-term reliability. This is where Parylene coating excels — acting as an ultra-thin, invisible shield that delivers durable, long-term protection.

Learn more about SCH Services’ specialist Parylene coating services here.

The Power of Parylene Coating

Unlike traditional conformal coating methods that are brushed, dipped, or sprayed, Parylene is applied using a specialised vapour deposition process. This process allows the coating to polymerise directly onto the surface, forming a uniform, pinhole-free layer that fully encapsulates components.

The result is a truly conformal barrier that coats not only visible surfaces but also sharp edges, internal geometries, and hidden crevices that liquid-applied coatings often struggle to reach.

Invisible Moisture Protection

Moisture remains one of the leading causes of electronic failure. Even minimal condensation can lead to corrosion, leakage currents, or short circuits. Parylene provides exceptional moisture resistance by forming a continuous microscopic film that significantly reduces water vapour ingress.

This makes Parylene particularly effective in harsh, humid, or environmentally demanding applications where traditional coatings may degrade or fail over time.

Why Industries Rely on Parylene

Industries such as aerospace, automotive, medical devices, and consumer electronics rely on Parylene because of its proven performance and reliability. It is lightweight, chemically resistant, biocompatible, and stable across a wide temperature range — making it suitable for applications where failure is not acceptable.

SCH Services Ltd – Your Partner in Invisible Protection

At SCH Services Ltd, we specialise in both liquid and Parylene conformal coating services, providing tailored solutions to meet specific environmental and performance requirements. Whether protection is needed against moisture, chemicals, or long-term environmental exposure, Parylene offers reliable defence against unseen threats.

Because in many applications, the best protection is the protection you never notice.

Parylene conformal coating protecting electronic assemblies from moisture, chemicals and environmental damage

5 Reasons Why Parylene is the Gold Standard for High-Reliability Applications

September 23, 2025 Parylene

Introduction: Why Parylene Stands Out

When it comes to protecting electronic assemblies, manufacturers have several conformal coating options available, including acrylics, silicones, urethanes, and epoxies. However, when performance, reliability, and long-term protection cannot be compromised, Parylene consistently stands apart as the industry benchmark.

At SCH Services Ltd, we provide a complete, end-to-end Parylene solution. Unlike providers that focus on a single element of the process, SCH supports the full lifecycle — from coating services and deposition systems to high-purity dimers, consumables, spares, consultancy, and training.

Whether you are outsourcing coating services, developing in-house capability, or strengthening your supply chain resilience, SCH delivers the expertise and infrastructure required to support electronics, aerospace, automotive, and medical applications.

Our focus is simple: dependable, scalable, and cost-effective Parylene solutions, backed by deep technical knowledge and proven industrial experience.

Learn more about SCH Services’ complete Parylene coating solutions here.

Below are five reasons why Parylene is widely regarded as the gold standard in conformal coating.

1. Superior Barrier Protection

Parylene forms an ultra-thin, pinhole-free polymer film that provides complete environmental protection against:

Moisture and humidity
Corrosive chemicals and solvents
Salt spray and aggressive environments

Because Parylene is applied in vapour form, it coats all exposed surfaces evenly, including sharp edges, crevices, and areas beneath components. This level of coverage significantly improves long-term PCB reliability compared with liquid-applied coatings.

2. Uniform, Truly Conformal Coverage

Parylene is deposited molecule by molecule within a controlled vacuum chamber, resulting in a coating that is:

Uniform across complex three-dimensional geometries
Ultra-thin, typically between 10 and 50 microns
Stress-free, with no pooling, bridging, or edge effects

This makes Parylene particularly well suited to miniaturised electronics and densely populated assemblies where conventional coatings struggle to perform.

3. Outstanding Chemical and Moisture Resistance

Parylene demonstrates excellent resistance to a wide range of environmental and chemical exposures, including:

Water vapour transmission
Fuels, oils, and industrial solvents
Acidic and alkaline solutions

In automotive, industrial, and outdoor electronics applications, this resistance translates into stable, predictable protection throughout the product lifecycle.

4. Biocompatibility for Medical Applications

Parylene’s biocompatibility is a key differentiator in medical and healthcare applications. Certified to ISO 10993 standards, Parylene coatings are:

Suitable for direct contact with human tissue and fluids
Widely used in implantable devices such as pacemakers and stents
Common in diagnostic equipment, sensors, and wearable technology

For medical device manufacturers, Parylene is not just a coating choice — it is a pathway to regulatory compliance and long-term device reliability.

5. Long-Term Reliability in Harsh Environments

Parylene remains stable across a wide temperature range, offers excellent dielectric strength, and resists UV and environmental degradation.

This makes it the coating of choice in demanding sectors such as:

Aerospace and defence – avionics, satellites, and radar systems
Automotive – electric vehicle systems and ADAS sensors
Telecommunications and IoT – outdoor and remote installations

Where downtime or failure is unacceptable, Parylene delivers consistent long-term protection.

When to Choose Parylene Versus Other Coatings

While Parylene offers unmatched performance in high-reliability applications, it may not always be the most economical solution for low-cost or easily repairable products. Alternative coatings may be suitable where:

Chemical exposure is minimal
Miniaturisation is not critical
Ease of repair is a priority

However, when reliability is critical and environmental exposure is unavoidable, Parylene remains the safest and most robust option.

Conclusion: The Benchmark for Reliability

From medical implants to aerospace electronics, Parylene has earned its reputation as the gold standard in conformal coating. Its unique vapour deposition process delivers uniform, durable, and biocompatible protection that liquid coatings cannot replicate.

The SCH Advantage: Services, Equipment, Dimers, and Training Under One Roof

September 18, 2025 Parylene

Within the Parylene industry, many providers focus on a single element of the process — offering coating services, supplying equipment, or distributing dimers. At SCH Services Ltd, we take a different approach. We deliver a complete, integrated Parylene total solution, combining coating services, turnkey systems, dimer supply, and training to give customers confidence, flexibility, and long-term reliability.

Learn more about SCH Services’ complete Parylene coating solutions here.

Why a Total Solution Matters

Organisations exploring Parylene typically share two core concerns:

Reliability – Will the coating process consistently meet performance, quality, and compliance requirements?
Scalability – Can the process start small and expand without disruption or rework?

When services, equipment, materials, and training are sourced from multiple providers, this often leads to mismatched processes, unclear accountability, and hidden costs. Working with a single, experienced partner removes these risks and creates a more controlled and predictable outcome.

What Is Parylene Coating and Why Is It Different From Other Conformal Coatings?

September 15, 2025 Parylene

In electronics and advanced manufacturing, protecting sensitive components from moisture, chemicals, and environmental stress is critical. Conformal coatings play a key role in improving reliability and reducing field failures — but not all coatings perform the same. Parylene stands out as a highly effective solution when coverage, consistency, and long-term performance matter most.

What Is Parylene?

Parylene is a family of thin, transparent polymer coatings applied using a chemical vapour deposition (CVD) process. Unlike liquid conformal coatings that are sprayed, brushed, or dipped, Parylene is deposited as a vapour in a vacuum chamber. This allows it to coat external and internal surfaces with a uniform, pinhole-free film.

Common Parylene types include:

Parylene N – Excellent dielectric properties and strong performance in high-frequency applications.
Parylene C – Widely used for outstanding moisture and chemical resistance.
Parylene F (AF-4) – Enhanced high-temperature stability and chemical resistance.

How Parylene Differs From Liquid Conformal Coatings

Application method – Vapour deposition in a vacuum chamber delivers even coverage without pooling, meniscus effects, or edge build-up.
Coverage – Parylene can penetrate tight gaps, coat under components, and reach complex geometries that liquid coatings often cannot.
Film properties – Typically ultra-thin (commonly 1–50 µm), transparent, flexible, and suitable for demanding environments.
Performance – Strong resistance to moisture and many chemicals, with stable electrical and dielectric characteristics.
Cleanliness – As a dry, solvent-free deposition process, Parylene avoids solvent residues and is well suited to sensitive applications including medical and aerospace electronics.

Liquid vs Parylene Coating

Where Is Parylene Used?

Medical devices – Catheters, sensors, pacemakers, and implantable or body-contact components.
Aerospace and defence – High-reliability electronics, sensors, and mission-critical assemblies.
Automotive – EV electronics, sensors, and ADAS-related components.
Consumer electronics – Wearables, IoT products, and microelectronics.
