IECQ (IEC Quality Assessment System for Electronic Components) is the worldwide approval and certification system for electronic components — providing standardized quality assessment procedures that enable semiconductor and electronic component manufacturers to demonstrate compliance with international specifications, reducing redundant testing and facilitating global trade.

What Is IECQ?

• Definition: An international quality assessment system operated by the IEC (International Electrotechnical Commission) that certifies electronic components, assemblies, and associated materials and processes meet defined quality and reliability standards.
• Scope: Covers active and passive components, electromagnetic components, printed boards, wire and cable, and related processes.
• Recognition: IECQ certificates are recognized in 30+ countries — a component certified in one country is accepted in all participating countries without re-testing.

Why IECQ Matters

• Global Market Access: A single IECQ certification replaces multiple national certifications — reducing time and cost for semiconductor companies entering international markets.
• Quality Assurance: Provides customers with independent third-party verification that components meet published specifications and reliability requirements.
• Supply Chain Trust: Buyers can source IECQ-certified components from any approved manufacturer with confidence in consistent quality.
• Counterfeit Prevention: IECQ certification processes include supply chain controls that help prevent counterfeit components from entering the market.

IECQ Schemes

• IECQ AP (Approved Process): Certifies manufacturing processes (soldering, plating, wire bonding) meet IEC standards — relevant for semiconductor packaging and assembly.
• IECQ AC (Approved Component): Certifies individual components meet published specifications — quality data packages verified by independent testing.
• IECQ AP-CAP (Counterfeit Avoidance Programme): Certifies that distributors and manufacturers have controls to prevent counterfeit components — critical for aerospace and defense supply chains.
• IECQ IT (Independent Testing Laboratory): Certifies test laboratories capable of performing component qualification testing per IEC standards.

IECQ vs. Other Standards

IECQ is the global passport for electronic component quality — enabling semiconductor manufacturers to certify once and sell worldwide while giving customers confidence that every component meets internationally recognized quality and reliability standards.
