1、 EIA STANDARD COMPONENT TRAY FOR AUTOMATED HANDLING EIA-948 August 2004 EIA STANDARDS ELECTRONIC COMPONENTS INDUSTRY ASSOCIATION ANSI/EIA-948-2004 Approved: August 9, 2004 Reaffirmed: November 15, 2011 EIA-948 NOTICE EIA Engineering Standards and Publications are designed to serve the public interes
2、t through 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 Standards and Publication
3、s shall not in any respect preclude any member or nonmember of ECIA from manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than ECIA members, whether the standard
4、 is to be used either domestically or internationally. Standards 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 obligation whatever
5、to parties adopting the Standard or Publication. This EIA Standard is considered to have International Standardization implication, but the International Electrotechnical Commission activity has not progressed to the point where a valid comparison between the EIA Standard and the IEC document can be
6、 made. This Standard 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 Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitati
7、ons before its use. (From Standards Proposal No. 5054 formulated under the cognizance of the Automatic Component Handling Committee (ACH). Published by ELECTRONIC COMPONENTS INDUSTRY ASSOCIATION 2004 Technology Strategy it can be always used for smaller sizes. So for example, if some manufacturer is
8、 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 3.1.2.1 B-tray box 3.1.2.2 B-tray stack in A-tray bo

10、ay 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 are placed into. The modular tray sizes enable als
11、o 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
