Our conformal spray coating system delivers with precision.
Programmable selective spray technology, applies a consistent, repeatable coating that protects your PCB.
Protective layering on (PCBs) to shield your sensitive electronic components from environmental damage. It’s ideal for complex assemblies where accuracy isn’t just nice to have, it’s essential.
Why choose selective spray coating?
- Uniform acrylic conformal coating every time
- High precision with exceptional repeatability
- Minimal overspray and reduced material waste
- Single-pass coating for faster processing
- Less masking, meaning shorter lead times
- Fully traceable process parameters for complete quality assurance
Acrylic vs silicone vs urethane vs epoxy vs parylene conformal coating — which is best?
If your printed circuit boards are destined for aerospace, automotive or industrial applications, urethane conformal coating is an excellent choice. Designed to withstand moisture, chemical fumes and harsh operating conditions, it provides long-lasting protection for electronic assemblies that need to keep performing when the environment isn’t being particularly friendly.
- Programmable dipping speed
- Adjustable drip-off time
- Consistent coating thickness
- Exceptional process repeatability
Why choose Urethane conformal coating?
Urethane conformal coating offers outstanding resistance to:
- Chemicals and solvents
- Abrasion and mechanical wear
- Humidity and environmental contamination
Its tough, durable finish makes it a popular option for high-reliability PCB assemblies operating in demanding industries where failure simply isn’t an option.
Things to consider
Once urethane has cured, it really commits to the relationship. Removing or reworking the coating can be extremely difficult, making repairs time-consuming and costly. If your electronics are likely to need future modifications, you may want to consider an alternative coating.
Epoxy Conformal Coating (ER)
When your priority is creating an incredibly tough protective barrier, epoxy conformal coating is hard to beat. Commonly used in rugged industrial environments, epoxy provides exceptional protection against chemicals, physical impact and environmental damage.
- Exceptional hardness and durability
- Excellent chemical resistance
- Strong protection against moisture and contaminants
- Long service life in demanding environments
Things to consider
Epoxy isn’t known for being forgiving. Most systems require precise mixing before application and, once cured, the coating becomes extremely difficult to remove. Repairs often involve specialist techniques such as micro-blasting. In other words, epoxy believes in “one and done.”
Parylene Conformal Coating (XY)
When only the very best protection will do, Parylene conformal coating sits in a class of its own. Widely used in medical devices, aerospace electronics, defence systems and miniature PCB assemblies, it provides an ultra-thin protective layer without adding unnecessary weight or thickness.
- Pinhole-free coverage
- Outstanding dielectric insulation
- Superior moisture and chemical protection
- Excellent performance on miniature and complex electronic assemblies
Things to consider
The application process requires specialist vacuum deposition equipment and, should repairs ever be required, localised rework is extremely challenging. It’s a bit like wrapping your PCB in an invisible suit of armour… incredibly effective, but not something you want to remove on a Friday afternoon.
