IEC TS 62686-1:2015

Overview - IEC TS 62686-1:2015 (Process management for avionics / ADHP COTS semiconductors)

IEC TS 62686-1:2015 defines minimum process and product requirements for commercial off-the-shelf (COTS) integrated circuits and discrete semiconductors used in aerospace, defence and high performance (ADHP) applications. The Technical Specification covers general requirements for high-reliability ICs and discrete devices when operated within the manufacturer’s published datasheet limits and in conjunction with IEC TS 62239-1. Edition 2 (2015) updates semiconductor test methods (IEC and JEDEC), adopts and adapts the STACK S/0001 specification, adds JEP148A (Physics of Failure risk and opportunity assessment), revises Annex A test information, and updates lead-free termination finish requirements.

Key topics and technical requirements

• Product/process controls: specification control, product discontinuance procedures, product or process change notification (PCN).
• Traceability & anti-counterfeit: lot and date-code traceability, shipment marking and age-on-delivery controls.
• Electrical & mechanical requirements: electrical testing, parameter assessment, device marking, moisture sensitivity, hermeticity and termination finish guidance.
• Qualification & reliability: qualification methodology, sample/test categories, maintenance of qualification, product monitor programme and accumulated test data.
• Testing and test codes: informative Annex A lists test codes (HTOL, HTRB, HTGB, latch-up, ESD, die shear, autoclave, etc.) and cross-references updated JEDEC and IEC semiconductor test methods.
• Quality, audit & supplier management: internal quality audits, subcontractor oversight, sampling plans, lot acceptance and supplier performance monitoring.
• Environmental, health & safety (EHS): device handling and materials compliance.
• Shipping & ESD controls: packaging, ESD protection, tape-and-reel, trays and magazine reuse rules.
• Single event effects (SEE) & failure analysis: monitoring, corrective action and warranty/suspension procedures.

Practical applications - who uses this standard

• Avionics OEMs and system integrators specifying COTS components for flight hardware.
• Component manufacturers and suppliers establishing ADHP process controls, PCN procedures and qualification evidence.
• Quality, reliability and procurement teams evaluating supplier performance, sampling plans and incoming inspection criteria.
• Test laboratories and failure analysis groups implementing JEDEC/IEC test methods and producing qualification reports.
• Defense and other high‑reliability industries that choose to adopt ADHP-aligned COTS controls.
