When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the
34、 responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activities within the Military Service or Defense Agency, or within the military services system commands. Packaging data retrieval is available from t
35、he managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity. 6. NOTES (This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. The chip r
36、esistors described herein are intended to be used in thick or thin film circuits where microcircuitry is intended; also for use in surface mounting applications. 6.2 Ordering data. The contract or purchase order should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery: O
37、ne 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 performs the group B tests or provides certification of comp
38、liance with group B requirements (see 4.4.1.2.1). 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
39、 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 growth of tin whiskers. For additional information on this matter, r
40、efer to ASTM-B545 (Standard Specification for Electrodeposited 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 orderi
41、ng or shipping resistors. Direct shipment to the Government is controlled by MIL-DTL-39032 that specifies a preventive packaging procedure. 6.5 Pulse applications. Designers are CAUTIONED on using the above resistors in high power pulse applications. Since they have not been qualified nor tested for
42、 such applications, damage and premature failure are possible. These resistors only see a one-time pulse (Short-time overload) as part of the group B inspection of MIL-PRF-55342. * 6.6 User of record.
