Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the resp

26、onsible packaging activity. 6. NOTES (This section contains information of general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. The intended use specified in MIL-PRF-12934 will be applicable to this specification. 6.2 Acquisition requirements. Acquisition docum

27、ents must specify the following: a. Title, number, and date of this specification, and the complete PIN (see 1.2). b. Unless otherwise specified (see 2.1), the versions of the individual documents referenced will be those in effect on the date of release of the solicitation. c. Packaging instruction

28、s (see 5.1). 6.3 PIN. This specification requires a PIN that describes technology and appropriate references to associated documents (see 1.2 and 3.1). Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-12934/2D 56.4 Tin whisker growth. The use

29、of alloys with tin content greater than 97 percent, by mass, may exhibit tin whisker growth problems after manufacture. Tin whiskers may occur anytime from a day to years after manufacture and can develop under typical operating conditions, on products that use such materials. Conformal coatings app

30、lied over top of a whisker-prone surface will not prevent the formation of tin whiskers. Alloys of 3 percent lead, by mass, have shown to inhibit the growth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6

31、.5 Changes from previous issue. The margins of this specification are marked with vertical lines to indicate where changes from the previous issue were made. This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and co

32、ntractors are cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal notations and relationship to the last previous issue.
