In the era of the Internet of Things, washing machines are rapidly developing in the direction of intelligent and frequency change. When developing a new generation of intelligent sensing washing machines, a well-known international household appliance brand faces multiple challenges: its core control board needs to operate stably under high humidity (RH > 90%), sudden changes in temperature (-20 ° C ~ 60 ° C), and frequent vibrations.
Washing machine circuit board filling
Multiple protection requirements in harsh environments The technical indicators presented by the customer are extremely challenging:
Protection class: IP68 (long-term immersion test)
Environmental adaptability: -60 ℃ ~ 150 ℃ cold and hot shock (500 cycles)
Electrical performance: dielectric strength≥3kV/mm, surface resistance 1×10^16Ω
Repairability: Support partial peeling repair (peeling force≤0.5N/mm)
Environmental requirements: Compliance with REACH SVHC 229 substances of high concern
Process adaptability: Compatible with selective coating equipment (spray valve accuracy ±25μm)
Recommended products: COATING 9060 silicone coating adhesive
9060 is a low viscosity single-component silicone resin protective coating, easy to use, after curing to form an optically transparent thin film, has excellent high-temperature resistance, weather resistance, electrical insulation performance and excellent water resistance, shock resistance and absorption expansion and contraction, corrosion resistance, leakage resistance. It can enhance the moisture and pollution resistance of electronic lines and components, prevent welding points and conductors from being eroded, also can play the role of shielding and eliminating electromagnetic interference, preventing short circuit, improving the insulation performance of circuit boards.
