Electronic Control (ECU) & Power Control Units (PCU) & Sensors

WACKER’s wide portfolio offers solutions for the special challenges associated with ECUs and PCUs. Our products protect electronics, provide functional safety and thermal management, and are easy to process and manufacture.

Thanks to effective thermal management and high heat resistance, our silicones meet power-conversion requirements in the automotive sector. Our latest adhesives feature quick adhesion build-up with minimum energy input (< 10 min at 60 – 80 °C) and special grades even enable oven-free processing.

Electronic Control Units (ECU)

The comfort, safety and fuel efficiency of modern automobiles are mostly determined by the quality of the electronic control devices. High-quality silicone elastomers with their special characteristics from our ELASTOSIL^®, SEMICOSIL^® and WACKER SilGel^® product series ensure that electronic control and safety systems operate efficiently and safely over the long term.

Benefits:

Low elasticity modulus over a wide temperature range
Reduction of mechanical and thermal stress
Highly reliable at temperatures between -90 °C and over 200 °C (special grades up to 230 °C)
Thermally conductive
Low-energy curing, rapid curing
Assist in the dissipation of heat (thermal management)
Non-bleeding, non-exuding
Fuel and oil resistant
High tear strength
Compressible

Applications:

Seal/bond housing components (CIPG, FIPG and preformed gaskets)
Protect electronic components by potting or encapsulating (incl. dam and fill)
Anti-locking systems
Engine control
Air-flow meters

Power Conversion Unit (PCU)

The silicones in our ELASTOSIL^®, SEMICOSIL^® and WACKER SilGel^® product series are highly heat resistant and meet the automotive industry’s power-conversion requirements by providing efficient heat management. Our latest adhesives feature quick adhesion build-up with minimum energy input (< 10 min at 60 – 80 °C) and special grades even enable oven-free processing.

General Benefits:

Dissipate heat (thermal management) by providing a durable coupling between the heat source (electronic device) and the heat sink (active or passive cooling system)
Protect against moisture, oxidation, chemicals and vibration
Extend service life and performance

Applications used for xEV power conversion:

Converters
Inverters
On-board chargers
Boosters
Inductive charging

Applications for high-voltage conversion units (400 V):

Conformal coating (PCB protection)
Sealing of connectors and housings
Selective (thixotropic) potting of power modules and IGBTs
Potting of sensitive electronics incl. dam and fill

Applications for low-voltage conversion units (12 V/ 48 V):

Thermally conductive gap fillers, encapsulants, pastes and adhesives
Sealing of connectors and housings
Potting

Applications as insulating materials:

Dielectric strength typically > 20 kV/mm
Volume resistivity (IEC 60093) > 10 Ω·c
