DCU/ECU
As the automotive electronic and electrical architecture evolves towards domain concentration and central computing platforms, DCU integration continues to increase, power density continues to increase, and higher requirements are placed on heat dissipation, protection and reliable connections. MCOTI adhesives have comprehensive properties such as thermal conductivity, sealing, bonding and insulation, which can effectively improve the thermal management efficiency and environmental adaptability of the controller, ensuring that electronic systems remain stable and reliable under long-term high-load operating conditions.

Thermal conductive potting glue
As the electronic and electrical architecture of new energy vehicles develops toward high integration and high power density, control modules such as DCU, ECU, OBC, and DC/DC have long faced complex working conditions such as high temperature, vibration, heat and humidity, and hot and cold cycles, which have put forward higher requirements for the heat dissipation efficiency and reliability of electronic components. Thermal conductive silicone potting glue can be used to encapsulate PCBs, power devices, magnetic devices, connectors, etc. in whole or in part. While providing excellent environmental protection, it can also achieve efficient heat conduction and stress buffering, improving the long-term operation reliability of the entire machine.
