In March/April 2019, a Chinese manufacturer of electric shared bicycles was working to develop a new e-bike design that would reduce manufacturing costs and weight while improving aesthetics and reliability. 

Customer Challenge

• Modern-day motor drives are integrating more complex power devices to manage growing energy efficiency requirements.  The customer’s next-generation motor controller required a thermal interface material (TIM) to manage new performance challenges and higher power densities. 
• As the IC power module is subjected to motor vibration, reliability and stability of the thermal interface material – with no material migration -- is critical to enable operational integrity.
• Any thermal material selected had to meet challenging metrics: Electrical isolation with high dielectric strength (>5000 Volts) and low thermal resistance are necessary to meet in-application conditions.
