PCB Lacquering

PCB Conformal Coating – Protective Lacquering for Reliable Electronics

Need to protect your PCBs from harsh environments? At TI-Electronic, we offer professional conformal coating (PCB lacquering) services to shield electronic assemblies from moisture, dust, chemicals, and mechanical stress. With over 30 years of experience in electronics manufacturing, we ensure durable, uniform coatings tailored to your product’s requirements.

💡 What is Conformal Coating?

Conformal coating is a thin protective film applied to the surface of a printed circuit board (PCB) to protect it from environmental stress. It “conforms” to the board’s shape, covering components and solder joints without affecting functionality.

Key Benefits of PCB Lacquering:

  • Moisture, humidity, and chemical resistance

  • Electrical insulation and corrosion protection

  • Prevents dust, oxidation, and short circuits

  • Ideal for high-reliability and outdoor electronics

  • Increases product lifespan and reduces failure rate

🔍 Our Conformal Coating Process

  1. Surface cleaning and degreasing

  2. Masking of no-coat areas (connectors, sockets)

  3. Coating application (manual, spray, or dip)

  4. Curing: thermal, UV, or air-dry

  5. Visual inspection & thickness testing

  6. Final functional test & packaging
