Micro Case Study

High Power and Thermal Cycling Capability

In 2018, we worked with a European electronics company in dire need of new power module solutions. Their existing modules struggled to manage power distribution and heat transfer across electric and hybrid-electric vehicles (EVs), decreasing performance and reliability.

CPS took charge of their power module replacement project, developing new AlSiC base plate designs that offered double-sided power module cooling. Compared with outdated, single-sided options, double-sided cooling utilizes heat sinks to remove thermal stress from both the top and bottom of the module at once.

Our solution improved heat transfer ability and reduced the burden of thermal load across modules – particularly valuable for managing the heat-intensive electrical components found in modern EVs.
