The series inverter is an important component in the solar power generation system, which converts the direct current generated by the solar panel into alternating current to supply the power grid or electrical equipment. Adhesives play a key role in the application of string inverters, which are mainly used to fix and seal the electronic components inside the inverter and protect the circuit board from the external environment. The following is the application scheme of adhesives in string inverters:
Potting:
SIPA 8230-15# A/B High thermal conductivity potting silicone
■ Inductance heat conduction potting, insulation protection, increase service life
■ 1:1 mixing ratio,3800mPa.s viscosity, flame retardant V0,RTI=150°C
■ ShoreA30, good noise absorption effect, heat conduction 1.5W/m.K, low hardening shrinkage
Sealant:
SIPC N9339 or 9435
■ Adhesive shell to improve sealing performance
■ RTV-1, single component, paste
■ It is also suitable for fixing devices such as large capacitance or inductance
Conformal coating:
UV 9060 Conformal Coating
■ Conformal coating protection for PCB
■ Single component, low viscosity, environmentally friendly
■ UV moisture dual curing
Thermal conductivity:
TCMP 1920
■ Heat dissipation of heating components
■ Thermal conductivity 2.0-6 W/m.K/3.0W/m.K
■ UL94 V-0,silicone grease can meet the printing process
Bonding:
EP 1767-1K
■ Bonding fixed inductor coil structure
■ 1:1 mixing ratio, the paste is slightly collapsed
■ PBT\PAPCB board) coil) nanocrystalline material, good adhesion
Fixation:
SIPC 9337 Thermal conductive silicone sealant
■ Good adhesion to PVC, TPE and other polar plastics
■ Stable mechanical and electrical properties between -60-200°C
■Paste, tack-free time <10 minutes
