BS EN 62421:2007

What is BS EN 62421 – Electronic modules about?

BS EN 62421 is an international standard that discusses the specifications for electronics assembly technology.

BS EN 62421 provides a generic standard of electronics modules on which their sectional standards are based.

BS EN 62421 provides a definition, business model, interface between the trading partners, and related areas of standardization of electronic modules. In addition, a generic set of tests for the method is provided.

Who is BS EN 62421 - Electronic modules for?

BS EN 62421 on the electronic modules useful for:

• Electronics engineers
• Designers of electronics modules
• Developers of electronics modules
• Electrical engineers
• Researchers for electronics assembly technology

Why should you use BS EN 62421 - Electronic modules?

An electronic module is a functional block that contains individual electronic elements and /or electronic packages, to be used in a next-level assembly. An individual module has an application-specific function, including electronic, optoelectronic, mechanical, or other elements.

Electronic modules may be categorized by the signal interface, for example:

• Wired module: a module that has only electrical interfaces (majority of present-day modules)
• Wireless module: a module that has a wireless interface
• Opto-electronic module: a module that has an optoelectronic interface
• Sensor module: a module that can input physical information
• Actuator module: a module that could output physical information

BS EN 62421 provides you with the minimum number of items, for which ratings need to be specified in sectional standards of electronic modules. It informs about each sectional standard that should describe the preferred values appropriate to the subfamily of the electronic modules involved.

BS EN 62421 recommends the electronic modules carrying large currents, separate current-carrying, and voltage measuring contacts as the module typically provides protection of its elements and packages to assure the required level of reliability.

BS EN 62421 helps the users to evaluate the resistance of electronic modules to harmonic vibration during transport or use. The vibration of a harmonic pattern is generated primarily by rotating, pulsating, or oscillating forces, such as occur in ships, aircraft, land vehicles, rotorcraft, and space applications, or are caused by machinery and seismic phenomena.

BS EN 62421 also assists users to evaluate the ability of electronic modules for use or storage at high temperatures. This high-temperature load test can be applied to evaluate the use at high temperatures and the high-temperature storage test for high-temperature storage.
