Additionally; a power mo
38、isture resistance test as specified in 4.6 shall be performed. 4.4.2 Certification. The acquiring activity may accept a certificate of compliance instead of performing group B inspection and the power moisture resistance test. 4.5 Short time overload. Resistors shall be tested in accordance with MIL
39、PRF-55342. The following details and exceptions shall apply: a. An overload dc test potential which will result in 5 times the rated wattage. b. Test board may have copper lamination in excess of the 70 micrometers copper (2 oz.) thickness as described in MIL-PRF-55342. c. Separate resistors shall
40、be used for short time overload and resistance temperature characteristic tests. 4.6 Moisture resistance. Resistors shall be tested in accordance with MIL-PRF-55342. The following details and exceptions shall apply: a. The test is to be performed on an annual basis. b. A 30 piece sample shall be use
41、d with 0 defects allowed. c. Step 7a shall not be applicable. 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 person
42、nel 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 Department or Defense Agency, or within the military services system commands. Packaging data retri
43、eval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.

NOTES (This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. Surface mount resistors are used in electronic circuits where space is a major concern.
45、6.2 Ordering data. The contract or purchase order should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery and one copy of the conformance inspection data or certification of compliance that parts have passed conformance inspection with each shipment of parts by the manu
46、facturer. c. Requirements for packaging and packing. d. Whether the manufacturer performs the group B inspection and the moisture resistance test or provides a certificate of compliance (see 4.4.2). e. If marking is required (see 3.8.1). 6.3 Tin whisker growth. The use of alloys with tin content gre
47、ater 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-pro
48、ne 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 User of record. Coordinatio
49、n of this document for future revisions is coordinated only with the suggested source of supply and the users of record of this document.
