Electric Vehicle Power Module

High-reliability socket solutions for thermally demanding EV applications

Electric vehicle (EV) power modules require interconnect solutions that can operate reliably under high temperatures while maintaining compact PCB layouts and consistent electrical performance. Harwin’s IMS-compatible socket solutions are engineered to meet these challenges, making them suitable for modern EV and automotive electronic systems.

Application

Harwin IMS socket solutions are commonly used in:

• Electric vehicle power modules

• IMS (Insulated Metal Substrate) PCBs

• Automotive control systems

• Automotive and street lighting applications

Engineering Background

IMS PCBs feature a copper circuit layer bonded to a thermally conductive dielectric and a metal baseplate (aluminium or copper). As the layers are electrically isolated and do not use plated through-holes, conventional through-board sockets are unsuitable for these applications.

The Challenge

EV designers require a connector solution that:

• Supports effective thermal management

• Sits above the PCB using a stand-off design

• Allows surface-mount termination

• Ensures accurate multi-pin alignment

• Supports Design for Manufacture (DFM) in high-volume production

Harwin Solution

IMS-Compatible Stand-off Socket Solutions

Designed to deliver reliable performance in demanding EV environments, offering:

• Stand-off configuration above the PCB

• Surface-mount termination

• Accurate and repeatable multi-pin alignment

• DFM-friendly assembly

• Reliable operation in high-temperature applications
