IEC 61076-4-100:2001

Overview

IEC 61076-4-100:2001 is an international standard published by the International Electrotechnical Commission (IEC) that specifies detailed requirements for printed board connectors with assessed quality. Specifically, it covers two-part connector modules with a grid pitch of 2.5 mm used for printed boards and backplanes in electronic equipment. This second edition standard ensures compatibility, quality assurance, and reliable performance of connectors essential for modern electronic systems.

The standard also corresponds to the IEC Quality Assessment System for Electronic Components (IECQ) specification number QC 480301XX0001, highlighting its importance for manufacturers and users committed to quality management and compliance in electronic components.

Key Topics

• Connector Design and Construction: Detailed specifications for two-part connectors including fixed board connectors (embases) and free board connectors (pins or plugs).
• Technical Characteristics: Includes electrical, mechanical, and climatic ratings such as voltage withstand, contact resistance, insertion and extraction forces, and vibration tolerance.
• Dimensional Requirements: Precise dimensions, including height, width, depth, and mating interfaces, ensuring interchangeability and correct assembly.
• Contact Arrangements: Guidelines on male contact arrangement for backplanes and contact positioning to optimize performance.
• Mounting and Assembly: Recommended methods and tooling for mounting connectors on printed circuit boards and backpanels with associated hole patterns and insertion specifications.
• Testing Procedures: Comprehensive test programs covering electrical continuity, insulation resistance, climatic conditions, mechanical endurance, and inflammability test criteria to validate connector reliability.
• Marking and Ordering Information: Specifications for connector type designation, marking, and ordering codes to support clear communication and procurement.

Applications

IEC 61076-4-100:2001 connectors are widely applicable across industries that require reliable interconnection solutions for electronic equipment involving printed circuit boards and backplanes. Typical applications include:

• Telecommunications: Ensuring secure and high-quality connections in telecom switches, routers, and base stations.
• Computing and Data Centers: Backplane connectors in servers and storage systems where high-density and reliable data transmission are critical.
• Industrial Automation: Robust connectors for control systems and instrumentation that demand mechanical integrity and environmental resilience.
• Consumer Electronics: Used in complex electronic assemblies where reproducible quality and standardized dimensions reduce manufacturing risks.
• Aerospace and Defense: Connectors with assessed quality supporting mission-critical and high-reliability electronic systems.
