When Does Your PCBA Need Conformal Coating?
Conformal coating helps protect exposed circuits against environmental conditions that can affect electrical reliability and long-term operation.
Protect Your PCB Assembly from Environmental Exposure
Choose protective coating based on your product's operating environment and electrical requirements.
- Moisture and humidity protection
- Dust and contamination resistance
- Chemical exposure protection
- Temperature cycling resistance
- Electrical insulation support
Conformal Coating Materials & Application Methods
Select the coating material that matches your environmental, thermal and maintenance requirements.
Acrylic Conformal Coating
Moisture protection with convenient removal and rework.
Silicone Conformal Coating
Flexible protection for temperature changes and thermal cycling.
Polyurethane Conformal Coating
Enhanced resistance to specified chemicals and environmental exposure.
Parylene Conformal Coating
Uniform thin-film coverage for complex PCB assemblies.
Precision Conformal Coating Application
LZJPCB selects the application method based on your PCB layout, coating material and protection requirements.
- Selective spray coating
- Brush and dip coating
- Precision masking
- Controlled coating thickness
- Material-specific curing
Spray, brush and dip apply to liquid coatings. Parylene availability and its separate vapor-deposition route are confirmed during review.
