Occupational Safety Training in Micro Manufacturing

1. Overview of Micros

a. What is a Micro?

A micro (abbreviated from “microphone”) is a device that records or converts sound into electrical signals. Micros are widely used in recording, broadcasting, television, online conferences, seminars, karaoke, and many other fields.

A micro consists of a sound sensor and an electronic circuit to convert sound into electrical signals. The sound sensor is usually a vibrating diaphragm (called a membrane) or an electrode assembly. When sound enters, it causes the diaphragm or electrode assembly to vibrate, generating a current representing the sound. The electronic circuit then amplifies the signal so it can be used for recording or transmitting to an audio system.

There are many different types of micros designed for various environments and applications, including condenser micros, dynamic micros, directional micros, omnidirectional micros, and many others.

b. Machinery used in micro production

The micro production process includes multiple stages, where various machinery and equipment are used to perform each step.

Some commonly used machinery and equipment in micro production include:

• Cutting machines: used to cut and process micro components, including the casing, diaphragm, and other parts.
• Soldering machines: used to solder micro components together, such as the diaphragm and connector ports.
• Plastic injection machines: used to mold plastic parts of the micro, including the casing and other components.
