Printed circuit boards
Fluoropolymers are used for copper-clad laminates (CCL), the key material in printed circuit boards. Fluoro substrates are flame retardant and have excellent dielectric properties. Common uses are high-frequency circuits for base stations and automotive millimeter wave radars.
Material for CCLs (copper-clad laminates)
- Dielectric properties
- Heat resistance
- Solder resistance
- Low water absorption
Daikin’s Fluoropolymer POLYFLON PTFE D-Series is an aqueous dispersion of Poly tetrafluoroethylene (PTFE) used to impregnating or coat a substrate such as glass cloth. Fluoropolymers with low water absorption suppress rust and slow the performance deterioration of copper foils, even under high temperature and high humidity conditions.
Waterproof / moisture-proof treatments for printed circuit boards
- Moisture resistance
- Quick drying
- Flame retardance
Malfunctions from water wetting can be prevented by using Daikin’s OPTACE to form a thin film layer on the surface of a printed circuit board (PCB). Daikin’s OPTACE conformal coating can be applied easily and safely within the PCB manufacturing process.
