Application note

Best practices in the manufacturing process

of MEMS microphones

Introduction

This application note serves as a reference concerning best practices in the manufacturing

process of MEMS microphones.These products have undergone thorough quality and

reliability testing as ST manufacturing processes have been carefully studied and

developed to achieve highly reliable devices. Section 1: Quality assurance details the

various tests performed on the microphones.

This document also provides recommendations to properly manage the microphones during

processes performed by the customer such as verification of the device upon reception,

proper handling of the device and production line considerations.
