PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as s

36、pecified in the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD personnel or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the In

37、ventory Control Points packaging activity within the Military Department or Defense Agency, or within the military services system commands. Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting th

38、e 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. Resistor networks are used in surface mounting applications where space is a major concern. 6.2 Ordering data. The contract o

39、r purchase order should specify the following: a. Complete 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 packag

40、ing and packing (i.e. ESD sensitive packaging). d. Whether the manufacturer performs the group B tests or provides certification of compliance with group B requirements (see 4.3.2). 6.3 PIN supersession. PINs in the original 87017 and revision A have been superseded by a new PIN in revision B that i

41、ncludes a characteristic code to differentiate between hermetically and nonhermetically sealed resistor networks. Table III illustrates a generic PIN substitution: TABLE III. PIN supersession. 87017 87017A nonhermetic 87017-87017X 87017-87017XM * 6.4 Tin whisker growth. The use of alloys with tin co

42、ntent 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 applied over top of a wh

43、isker-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). 6.5 Electrostatic char

44、ge. 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 Government is controlled by MIL-DTL-39032 which specif

45、ies a preventive packaging procedure. * 6.6 Pulse applications. Designers are CAUTIONED on using the above resistors in high power pulse applications. Since they have not been qualified nor tested for such applications, damage and premature failure are possible. * 6.7 User of record. Coordination of
