The marking shall remain legible after all tests. 3.12 Manufacturer eligibility. To be eligible for listing as an approved source of supply, a manufacturer shall be lis
31、ted on the MIL-PRF-55182 Qualified Product List for at least one part, or perform the group A and group B inspections specified herein on a sample of parts agreed upon by the manufacturer and DLA Land and Maritime-VAT. 3.12.1 Certificate of compliance.

The product level qualification specified in MIL-PRF-55182 and MIL-STD-690 is not applicable to this document. 4.4 Conformance
36、 inspection. 4.4.1 Inspection of product for delivery. Inspection of product for delivery shall consist of group A inspection (ER level only) and group B inspection of MIL-PRF-55182. 4.4.1.1 Certification.

37、. 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 activity to ascer
38、tain requisite packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activity within the Military Department or Defense Agency, or within the Military Departments Services System Command. Packaging data retrieval is available from the managing Milita
39、ry 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. Chip resistors are intended
40、to be used in thick or thin film circuits where microcircuity is intended, also, for use in surface mounting application. 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 da
41、ta or a certificate of compliance that parts have passed conformance inspection with each shipment of parts by the manufacturer. c. Packaging requirements (see 5.1). (i.e. Electrostatic discharge sensitive packaging). d. Whether the manufacturer performs the group B tests or provides certificate of
42、compliance with group B (see 4.4.1.1). 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
43、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 AST
44、M-B545 (Standard Specification for Electrodeposited Coatings of Tin).
