Conformal coating enhances system reliability by protecting electronic components against contaminants such as pollution, dust, and condensation, which may cause corrosion. Power Integrations’ factory-coated gate drivers reduce inventory cost, lead time and overall cost of ownership by eliminating the need for manufacturers to send boards to subcontractors for cleaning and coating.
“Customers in wind inverters, traction inverters, HVDC MMC stations, photovoltaics and industrial drives where harsh environments are routinely encountered benefit from a factory conformal-coating process,” explains Michael Hornkamp, Senior Director of Marketing for gate-driver products at Power Integrations. “By testing, cleaning, and coating the boards in our facility, we reduce the opportunity for the units to be contaminated prior to coating, and we eliminate the time, cost and inconvenience of using third-party subcontractors.”
Power Integrations uses an advanced acrylic lacquer, broadly used in the industrial and automotive sectors. The highly automated process is qualified in accordance with IEC 60068-2 tests and is followed by 100% optical inspection to ensure consistent quality. Conformally coated SCALE gate-driver cores are UL® recognized components.
Initially, the 2SC0106T, 2SC0108T, 2SC0435T, 2SP0115T, and 1SP0335 gate-driver families will be offered with conformal coating, followed by the 2SD300C17, 2SC0535T, 2SC0635T, 2SP0320, and 1SP0635V series in the near future. All future products will also include factory coating as an option.
