34、 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 mate
35、rials. 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 Electro
36、deposited Coatings of Tin). 6.4 Electrostatic charge. Under several combinations of conditions, these resistors can be electrically damaged, by electrostatic charges, and drift from specified value. Users should consider this phenomena when ordering or shipping resistors. Direct shipment to the Gove
37、rnment is controlled by MIL-DTL-39032 which specifies a preventive packaging procedure. 6.5 User of record. Coordination of this document for future revisions is coordinated only with the suggested source of supply and the users of record of this document. Requests to be added as a recorded user of
