Requirements for delivery: One copy of the conformance inspection data that parts have passed conformance inspection

32、, with each shipment of parts by the manufacturer. c. Bulk packaging requirements (see 5.1). d. Whether the manufacturer performs the group A, dc resistance sample test data (see 4.3.2). e.

33、. 6.3 Tin whisker growth. 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 from a day to years after manufacture and can develop under typical operating conditions, on products that use such

34、 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 growth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for El

35、ectrodeposited Coatings of Tin). 6.4 User of record.
