32、MIL-PRF-55342. 5. PACKAGING * 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging

33、 activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory 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

34、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. Resistors conforming to this dr

35、awing are intended for use when military specifications do not exist and qualified military devices that will perform the required function are not available for the OEM application. These items are suited for high current pulse applications and can be used as microwave terminations. 6.2 Ordering da

36、ta. The contract or purchase order should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery. One copy of the conformance inspection data with each shipment of parts by the manufacturer. c. Packaging requirements (see 5.1). (i.e. Electrostatic discharge (ESD) sensitive pa

37、ckaging). d. Whether the manufacturer performs the group B tests or provides certification of compliance with group B requirements (see 4.4.1.2.1). 6.3 Electrostatic charge. Under several combinations of conditions, these resistors can be electrically damaged, by electrostatic charges, and drift fro

38、m specified value. Users should consider this phenomena when ordering or shipping resistors. Direct shipment to the Government is controlled by MIL-DTL-39032 that specifies a preventive packaging procedure. * 6.4 Tin whisker growth. The use of alloys with tin content greater than 97 percent, by mass

39、, 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 whisker-prone surface will not prevent t

40、he 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). Provided by IHSNot for ResaleNo reproduction or networking p
