IEC 60286-3:2019

Overview

IEC 60286-3:2019 - "Packaging of components for automatic handling - Part 3: Packaging of surface mount components on continuous tapes" is the international standard that defines tape-and-reel packaging requirements for surface-mount components (SMT) and singulated die (bare die, bumped die/flip chips). It specifies the essential dimensional, mechanical and marking characteristics for carrier tape, cover tape and reels used in automated handling and pick-and-place assembly.

This 2019 edition (Edition 6.0) updates tape classification and symbols, adds examples for polarity/orientation and dot seals, revises camber requirements and introduces a design value definition for component tilt.

Key Topics and Technical Requirements

• Scope: Applies to components without leads or with lead stumps intended for connection to electronic circuits, including singulated die products.
• Tape types: Defines requirements for multiple carrier tape styles (punched, pressed, blister, adhesive-backed) and standard tape widths and pitches.
• Dimensional requirements: Cavity geometry, pocket pitch, maximum offsets, tilt, planar rotation and lateral displacement limits for component positioning.
• Carrier and cover tape: Material, minimum bending radius, camber limits, peel-force criteria and cover-seal methods (including dot seals for thin components).
• Reel requirements: Standard reel dimensions, hub and hole tolerances, labelling areas, leader/trailer configuration and tape reeling rules.
• Die and flip-chip handling: Specific requirements for tape design, cleanliness, die lateral movement control and coordinate referencing for singulated die.
• Measurement and testing: Normative annex on measuring methods for carrier thickness, cavity dimensions and depths.
• Symbols and classification: Table of symbols concerning tape, reel and common markings to support compatibility across the supply chain.

Practical Applications

• Ensures compatibility with automated pick-and-place machines and feeders used in PCB assembly lines.
• Standardizes tape-and-reel packaging for component suppliers, contract manufacturers (EMS) and PCB assemblers to reduce misfeeds, damage and downtime.
• Guides design of packaging for bare die and flip-chip distribution where cleanliness and precise positioning are critical.
• Supports procurement and quality assurance in electronics manufacturing for vendor compliance and incoming inspection.

Who Uses IEC 60286-3:2019
