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-hou
19、se contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activity within the Military Service or Defense Agency, or within the military services sys
20、tem commands. Packaging data retrieval is available from the 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 he
21、lpful, but is not mandatory.) 6.1 Intended use. Chip resistors are intended to be use in thin or thick film hybrid circuits where microcircuitry is indicated and in surface mount applications. 6.2 Acquisition requirements. Acquisition documents should specify the following: a. Title, number, date of
22、 this specification, the applicable associated specification, and the complete PIN (see 1.2). * b. Unless otherwise specified (see 2.1), the versions of the individual documents referenced will be those in effect on the date of release of the solicitation. c. Packaging requirements (see 5.1). d. If
23、marking is required (see MIL-PRF-32159). 6.3 Tolerance for wraparound termination. The added tolerance for the wraparound type termination is intended to apply only to termination, metallization, and pretinning material. * 6.4 Electrostatic charge effects. Under relatively low humidity conditions, s
24、ome types of film resistors, particularly those with small dimensions and high sheet resistivity materials, are prone to sudden significant changes in resistance (usually reductions in value) and to changes in temperature coefficient of resistance as a result of discharge of static charges built up
25、on associated objects during handling, packaging, or shipping. Substitution of more suitable implements and materials can help minimize this problem. For example, use cotton gloves, static eliminator devices, air humidifiers, and operator and workbench grounding systems can reduce static buildup dur
26、ing handling. Means of alleviating static problems during shipment include elimination of loose packaging of resistors and use of metal foil (conductive) and static dissipation packaging materials. Direct shipments to the government are controlled by MIL-DTL-39032 which specifies a preventive packag
27、ing procedure. * 6.5 Pulse applications. Designers are CAUTIONED on using these resistors in high power pulse applications. Since they have not been qualified nor tested for such applications, damages and premature failures are possible. These resistors only see a five second short time overload as
28、part of the group B inspection of MIL-PRF-32159.
