DAYTON, OHIO A 14933 87016 REV N PAGE 4 3.3.10.1 Failure criteria for leadless packages. The criteria for acceptable solderability during evaluation of the terminations are: a. The total surface area of the dipped part of the termination is at least 95 percent covered by a continuous new solder coating. b. That pinholes, voids, porosity, nonwetting, or dewetting are not concentrated in one area and do not exceed 5 percent of the total metallized termination area. c. That there shall be no solder bridging between any termination area and any other termination area not connected to it by design. In the event that the solder dipping causes bridging, the test shall not be considered a failure provided that a local application of heat (i.e., gas, soldering iron, or redipping) results in solder pullback and no wetting of the dielectric area is indicated by microscope examination at a magnification of between 10 and 20x. That area of the surface to be tested as specified in 4.6c shall include the total metallized area of both the castellations and the terminal pads. In case of a dispute, the percentage of coverage with pinholes or voids shall be determined by actual measurement of these areas, as compared to the total area. 3.4 Environmental characteristic. The environmental characteristics shall be in accordance with MIL-PRF-914 characteristic C, H, K, R, or V, except for RTC (see 3.3.6). 3.5 Marking. Marking shall be in accordance with MIL-STD-1285, except the PIN shall be as specified in 1.2, with the manufacturer's CAGE number or trade mark and date code. 3.6 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs. * 3.7 Manufacturer eligibility. To be eligible for listing as a approved source of supply, a manufacturer shall be listed on the MIL-PRF-914 Qualified Products List for at least one part, or perform the group A and group B inspections specified herein on a sample agreed upon by the manufacturer and DLA Land and Maritime-VAT. * 3.7.1 Certificate of compliance.

DAYTON, OHIO A 14933 87016 REV N PAGE 6 4.4 Inspection of packaging. Inspection of packaging shall be in accordance with MIL-PRF-914. 4.5 “B” schematic tests. For the tests on “B” schematic, the dc resistance measurements, resistance temperature characteristics measurement, and short time overload power application shall be made between each terminal and the application common terminal without compensation for the shunt circuits. The pin to pin dc resistance measurements shall be used directly to determine the acceptability to section 3 requirements. 4.6 Solderability. Solderability shall be in accordance with method 208 of MIL-STD-202. The following details shall apply: a. Application of flux. Flux type shall be in accordance with MIL-PRF-914. Terminations shall be immersed in the flux, which is at room ambient temperature, to the minimum depth necessary to cover the surface to be tested. The terminations shall be completely immersed by individually dipping each edge with the Y1 axis 30 degrees to 45 degrees from vertical. The terminations to be tested shall be immersed in the flux for a period of 5 seconds to 10 seconds. b. Solder dip. The dross and burned flux shall be skimmed from the surface of the molten solder. (NOTE: May not require separate operation in wave or flow pot). The molten solder shall be maintained at a uniform temperature of 245°C ±5°C. The surface of the molten solder shall be skimmed again prior to immersing the terminations in the solder. The part shall be attached to a dipping device and the flux covered terminations immersed, one side at a time, in molten solder to the depth, and in the same manner specified in 4.6a. The immersion and emersion rates shall be 1.000 ±.250 inch per second and dwell time in the solder bath shall be 5.0 seconds ±0.5 second. After the dipping process, the part shall be allowed to cool in air. Residue flux shall be removed from the terminations by rinsing in a suitable solvent. If necessary, a soft cloth or cotton swab moistened with clean 91 percent isopropyl alcohol shall be used to remove all remaining flux. c. Examinations of terminations. After each dip coated termination has been thoroughly cleaned of flux, the castellation and pad shall be examined using a magnification between 10x and 20x. 4.7 Visual and mechanical examination. Resistors shall be examined to verify that the materials, design, construction, physical dimensions, marking, and workmanship are in accordance with the applicable requirements of MIL-PRF-914. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD personnel 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 that may be helpful, but is not mandatory.) 6.1 Intended use. Resistor networks are used in surface mounting applications where space is a major concern. DEFENSE ELECTRONIC SUPPLY CENTER SIZE CODE IDENT NO. DWG NO. DAYTON, OHIO A 14933 87016 REV N PAGE 7 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 certification of compliance that parts have passed conformance inspection with each shipment of parts by the manufacturer. c. Requirements for packaging and packing (i.e. ESD sensitive packaging). d. Whether the manufacturer performs the group B tests or provides certification of compliance with group B requirements (see 4.3.2). 6.3 PIN supersession. PIN's in the original 87016 and revision A have been superseded by a new PIN in revision B that includes a characteristic code to differentiate between hermetically and nonhermetically sealed resistor networks. Table III illustrates a generic PIN substitution: TABLE III. PIN supersession. 87016 and 87016A 87016-****** 87016B Nonhermetic 87016-******V 87016-******H 87016B Hermetic 87016-******C 6.4 Electrostatic charge. Under several combinations of conditions, these resistors can be electrically damaged, by electrostatic charges, and drift from specified value. Users should consider this phenomena when ordering or shipping resistors. Direct shipment to the Government is controlled by MIL-DTL-39032 which specifies a preventive packaging procedure. * 6.5 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). * 6.6 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. * 6.7 User of record. Coordination of this document for future revisions is coordinated only with the approved source of supply and the users of record of this document.
