EWJEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers,
3、facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for use by those other than JEDEC members, whether the standard is to be used either domestically or internationally. EWJEDEC standards and public

By such action JEDEC does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the EWJEDEC standards or publications. T
5、he information included in EWJEDEC standards and publications represents a sound approach to product specification and application, principally from the solid state device manufacturer viewpoint. Within the JEDEC organization there are procedures whereby an EWJEDEC standard or publication may be fur

The purpose of this publication is to provide a distinctive symbol a

22、 4.3.3 Level 6 Level 6 devices must be identified as “EXTREMELY MOISTURE SENSITIVE”. See Figure 5. This label is required on the moisture barrier bag andor the lowest level shipping container. The label must specify the peak package body temperature at which the device was classified. If the require
23、d information is not provided on the caution label then it must be on the adjacent bar code label. Level 6, as defmed by J-STD-020, does not require that devices be shipped in a moisture-barrier bag with desiccant, etc. (dry-pack), since these devices require baking by the end user before use. Howev
24、er, moisture-barrier bags have become a “symbol” for moisture-sensitive devices and therefore are recommended to be used with level 6 device shipments. It is also recommended that these bags be sealed even though desiccant and humidity indicator cards (HIC) may not be inside the bags. CAUTION EXTREM

These labels shall be legible to normal vision at a distance of three feet. Monochromatic reproduction in any col
28、or that contrasts with the background may be used. Where the choice of color is arbitrary, it is suggested that: 1) The ID label background be blue (Pantone #297C) with a black symbol and letters. 2) The caution label background be white with a blue (Process blue) symbol and letters. Wherever possible the color red should be avoided as red suggests a personal hazard. JFiDEC Publication No. 113-B Page 6
