NOTES (This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. Resistors conforming to this drawing are intended for use when military

29、 specifications do not exist and qualified military devices that will perform the required function are not available for the OEM application, described herein are intended to be used in surface mount applications. 6.2 Ordering data. The contract or purchase order should specify the following: a. Co

30、mplete PIN (see 1.2). b. Requirements for delivery: One copy of the conformance inspection data or certification of compliance that parts have passed conformance inspection with each shipment of parts by the manufacturer. c. Requirements for packaging and packing. d. Whether the manufacturer perform

31、s the group B tests or provides certification of compliance with group B requirements. If purchase order makes no reference to group B screening the manufacturer will provide a certification of compliance (see 3.6.1).

The use of alloys with tin content greater than 97 percent, by mass, may exhibit tin whisker growth problems after manufacture. Tin whiskers may occur anytime f

33、rom a day to years after manufacture and can develop under typical operating conditions, on products that use such materials. Conformal coatings applied 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 gr

34、owth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.4 User of record. Coordination of this document for future revisions is coordinated only with the approved source of supply and the users of record of
