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 activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Point's packaging activity within the Military Department or Defense Agency, or within the military service’s system commands. Packaging data retrieval is available from the managing Military Department's or Defense Agency's 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, which may be helpful, but is not mandatory.) 6.1 Intended use. Chip resistors are intended for use in thick or thin film circuits where microcircuitry is intended. Resistors are also for use in surface mount applications. 6.2 Ordering data. 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 or certificate 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 compliance with group B requirements (see 4.4.2.1). DEFENSE ELECTRONICS SUPPLY CENTER SIZE CODE IDENT NO. DWG NO. DAYTON, OHIO A 14933 88033 REV H PAGE 7 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 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 Electrodeposited Coatings of Tin). 6.4 PIN supersession. PIN’s of revision C of this document have been superseded by a new PIN in revision D that includes a combination resistance value and resistance tolerance in accordance with MIL-PRF-55342 and herein. 6.5 Electrostatic charge. Under several combinations, these resistors can be electrically damaged, by electrostatic charges, and drift from specified value. Users should be considered this phenomena when ordering or shipping resistors. Direct shipment to the Government is controlled by MIL-DTL-39032 which specifies 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. These resistors only see a one time pulse (Short-time overload) as part of the group B inspection of MIL-PRF-55342. * 6.7 User of record.
