As industries push the boundaries of miniaturisation to deliver high-performance, cost-efficient sensor solutions, precision alignment in Micro-Opto-Electro-Mechanical Systems (MOEMS) has emerged as a critical challenge.
The need for smaller and more energy-efficient systems demands cutting-edge manufacturing techniques and innovative design approaches.
In 2024 ESCATEC Switzerland AG, our MOEMS team were tasked with developing a groundbreaking solution to address this challenge.
Their mission was to enable the precise assembly of high-end Time-of-Flight (ToF) LiDAR sensors, a cornerstone technology in applications ranging from autonomous vehicles to medical devices, while ensuring cost-efficiency and scalability for mass production.
Micro-Opto-Electro-Mechanical Systems (MOEMS) combine optical, electronic, and mechanical components at microscopic scales. These systems are fundamental in advanced applications, including:
Automotive LiDAR systems for autonomous driving
Medical imaging devices for precise diagnostics
Telecommunication components for high-speed data transfer
ESCATEC sought to design and implement a reliable, cost-effective process for assembling MOEMS components, with a specific focus on:
Achieving sub-10 µm alignment precision.
Reducing errors and deviations caused by manufacturing tolerances.
Optimising assembly for scalability and cost-efficiency.
