1、 EIA STANDARD Component Tray for Automated Handling EIA-948 June 2004 Electronic Components Industry Association EIA-948 ANSI/EIA-948-2004 (R2017) Approved: August 9, 2004 Reaffirmed: February 10, 2017 NOTICE EIA Engineering Standards and Publications are designed to serve the public interest throug

2、h eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Specifications and Publications s

Specifications and Publications are adopted by ECIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, ECIA does not assume any liability to any patent owner, nor does it assume any obl

5、igation whatever to parties adopting the Specification or Publication. This EIA Specification is considered to have International Standardization implications, but the International Electrotechnical Commission activity has not progressed to the point where a valid comparison between the EIA Specific

6、ation and the IEC document can be made. This Specification does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Specification to establish appropriate safety and health practices and to determi

(From Standards Proposal No. 5379, formulated under the cognizance of the Committee on EIA Automated Component Handling Standards) Published by Electronic Components Industry Association 2017 EIA Standards it can be always used for small

8、er sizes. So for example, if some manufacturer is supplying materials in all 4 tray sizes, it can keep only A-tray box and 2 different divider types in storage. The manufacturer is able to supply all shipments by using A-tray box and combinations of dividers. 3.1.1 A-tray box 5 (24) 3.1.2 B-tray 3.1

10、llet 1200x800 mm (so called Euro-pallet) 3.2.1 Tray stacks in boxes on pallet Tray boxes can be loaded to pallets directly and then wrapped with stretch or shrink film, or even placing collar around the stacks and then cover on top. It is possible also to use bigger container box, where the stacks a

11、re placed into. The modular tray sizes enable also that several different sizes of trays are loaded to trays with high packing density. It is recommended that D-trays are always packed to boxes, because the high stacks can be very unstable and difficult to handle. The security issues must be taken into account, when choosing outer packaging method. 3.2.1.1 A-tray 10 (24) 3.2.1.2 B-tray 3.2.1.3 C-tray
