In new energy vehicles, energy storage systems, and industrial control equipment, electrode controllers play an important role in current control and signal processing.
Due to its internal integration of power devices, control chips, electrode interfaces, and drive circuits, it will face complex environments such as high temperature, humidity, vibration, and electrical shock during long-term operation.
Thermal conductive sealant for industrial controllers
Thermal conductive sealant for industrial controllers
If there is a lack of reliable packaging protection, it is easy to:
Moisture in components can cause short circuits or failures
High power devices generate heat, resulting in excessive temperature rise
Fatigue of solder joints or loosening of components under vibration environment
Dust or corrosive gases entering, causing a decrease in electrical performance
Therefore, in the fields of industrial electronics and automotive electronics, potting has become a key link in the reliability design of electrode controllers.
Why does the electrode controller need encapsulation protection?
Electrode controllers are typically used for:
New energy vehicle system
Electric vehicle charging equipment
Energy storage battery management system
Industrial control equipment
Inverter power module
These application environments generally have the following characteristics:
- High temperature operating environment
Power MOS, IGBT and other devices will continue to generate heat during operation. If the heat dissipation design is insufficient, it may lead to performance degradation or even failure. - Moisture and environmental erosion
In outdoor equipment or industrial environments, air humidity, dust, and corrosive gases can all affect the stability of electronic systems.
3 Mechanical vibration and impact
New energy vehicles and industrial equipment experience significant vibrations during operation, requiring colloids to provide buffering and fixing effects. 4. High electrical insulation requirements
The internal circuit of the electrode controller is dense and requires good electrical insulation protection to prevent leakage and breakdown.
Therefore, an excellent potting material needs to possess both:
Thermal conductivity
electrical insulation performance
Waterproof and moisture-proof performance
Low stress protection
Ability to withstand high and low temperatures
