Module package for Broadcom 3D-TOF sensors

Broadcom Inc. is a global technology leader that designs, develops, and supplies a broad range of semiconductor, enterprise software, and security solutions.

 

Broadcom’s category-leading product portfolio serves critical markets including cloud, data center, networking, broadband, wireless, storage, industrial, and enterprise software.

 

IFPD, one of Broadcom’s 26 divisions, is leveraging on their deep know-how in electrooptical IC-design and expanding their product portfolio towards optical sensing with the 3D-TOF distance sensor being an integral part of it.

The Challenge

IFPD was looking to bring its powerful TOF-ASIC into an adequate package and release a high-end 3D ToF-sensor to the market. This new addition to their product portfolio would help their customers power drones, robotics, and factory automation applications in a range of demanding settings.

Due to the high requirements for the optical performance of the device IFPD asked for specialist support to collaborate on an optical package for their cutting-edge lens and ASIC technology.

The Solution

Broadcom collaborated with ESCATEC, leveraging their expertise in packaging, Chip-on-Board (CoB) processes, and advanced optical engineering to develop a compact and efficient 3D Time-of-Flight (ToF) sensor module.

The ESCATEC team supported Broadcom in achieving their ambitious target to develop a miniaturised package design for the cutting-edge 3D-ToF sensor, utilising standard PCB technology and iterate their innovative design against tight time scales, as they raced to complete in a rapidly evolving sensor market.

The Results

The project moved from initial contact to mass production in just over 2 years highlighting ESCATEC's efficiency in process development and prototype validation.

ESCATEC’s DfM and Value Engineering support helped define the NPI requirements for when the design was handed over to Broadcom’s manufacturing team.

 

The support extended beyond initial development, providing troubleshooting and technical transfer assistance to the manufacturing site. Eventually, the sensor has become the benchmark in range-performance in challenging conditions on the market.

 

The successful collaboration on the 3D-ToF sensor laid the foundation for an ongoing partnership, with Broadcom returning to ESCATEC for new projects and complex product developments.

It’s been an exciting journey together with the very skilled and professional team from ESCATEC. We’ve learned a lot during our project.
