Overview
IEC 60286-5:2018 - "Packaging of components for automatic handling – Part 5: Matrix trays" specifies the essential dimensions, tolerances and characteristics of matrix trays used to store and transport electronic components for automated handling. The standard focuses on the features necessary for reliable placing and removing of components by automated equipment and establishes generic design rules so newly developed trays that comply are accepted as standard trays. Trays that do not conform are listed as non-standard trays (Annex A) and are not preferred.
Key topics and technical requirements
- Tray design rules: Generic rules for pocket layout, orientation and pocket density so trays are interoperable with automated handling systems.
- Dimensions and tolerances: Overall tray dimensions, cell (pocket) geometry and critical tolerances required for consistent pick-and-place performance.
- Material properties: Requirements including electrostatic dissipative behaviour, rigidity, recycling considerations and how material affects handling.
- Mechanical stability: Criteria for loaded and empty tray stiffness, outer edge strength and resistance to warpage to maintain alignment during automated transport and stacking.
- Vacuum pick-up sites: Location and size guidance for vacuum tooling engagement points used by automatic handlers.
- Stacking and protection: Rules for stack-up, bundling, top protection, partial filling, protrusion management and avoiding component damage.
- Measurement and verification: Normative measurement methodology for tray dimensions and warpage (Annex B) to support quality control and supplier compliance.
- Design considerations: Practical checks for lateral movement, lead protection and other design values (Annex C).
- Identification and marking: Minimum marking and documentation expectations for traceability and automated processing.
Practical applications and users
IEC 60286-5 is used by:
- Electronic component manufacturers and packaging engineers to design compliant matrix trays.
- Component suppliers and distribution centers to supply components in compatible packaging.
- PCB assembly and contract manufacturers (CMs) that use pick-and-place and automated handling equipment.
- Equipment makers integrating vacuum pickups and feeders who require standard tray dimensions for tooling.
- Procurement and quality teams verifying supplier tray conformity and minimizing handling errors.
Benefits include improved automation compatibility, reduced tooling changes, better component protection and clearer supplier acceptance criteria.
