ANSI EIA 948-2004 pdf download COMPONENT TRAY FOR AUTOMATED HANDLING
1 Scope
This Standard covers requirements for component trays used during automated handling.
2 Introduction
This Standard was formulated to provide dimensions and tolerances necessary for trays to locate components in known positions for automated handling. Trays can also be used as shipment packages in the logistic chain. Overall tray dimensions are based on flat pallets of 1200×800 mm and 12 19×1016 mm for intercontinental materials handling according to ISO-6780:2003.
3 Applicable Documents
Unless otherwise specified the following documents form a part of this standard to the extent specified herein:
EU-3 83 “Preparation for the Delivery of Electrical and Electronic Components”
EM-541 “Packaging Material Standards for ESD Sensitive Items”
EM-624 “Product Package Bar Code Label Standard for Non-Retail Applications”
ISO-2768-2 “Geometrical Dimensioning and Tolerancing”
ISO-1043-1 “Plastics – Symbols and abbreviated terms”
ISO-6780:2003 “Flat pallets for intercontinental materials handling – Principal dimensions and tolerances”
4 Requirements
4.1 Component trays must meet the requirements defined in the Figures and Tables presented herein.
4.2 Use of the cut edge of the tray as a locating feature may cause functional problems with component tray feeding.
4.3 The packaging, materials and processes shall not adversely affect the mechanical and electrical characteristics or marking of the components. For intermediate and final packaging, refer to EIA-383 “Preparation for the Delivery of Electrical and Electronic Components,” EIA-54 1 “Packaging Material Standards for ESD Sensitive Items,” and EIA- 624 “Product Package Bar Code Label Standard for Non-Retail Applications.”
4.4 The tray shall withstand, without any adverse effects, a wide range of temperatures during transit and storage. The tray shall also be within stated dimensional tolerances inside the range of acting temperatures:
Acting temperature min. +18″ C
max. +32″ C
Transit and storage temperature min. -40″ C
max. +60″ C
Acting temperature is the temperature at which the tray is expected to be used or measured.
The tray should be stabilized at least 24 hours in this temperature range prior to use or measurement.
Transit and storage temperature range is the temperature span that the tray must endure, but during which time the dimensional tolerances are not required to be met.
