4. VERIFICATION
4.1 Qualification inspection. Qualification inspection is not applicable to this document.
4.2 Reliability assurance program. The reliability assurance program specified in MIL-PRF-55342 and maintained in accordance
with MIL-STD-790 is not applicable to this document.
4.3 Failure rate qualification. Failure rate qualification specified in MIL-PRF-55342 and MIL-STD-690 is not applicable to this
document.
4.4 Conformance inspection.
*
4.4.1 Inspection of product for delivery. Inspection of product for delivery shall consist of group A inspection (ER level only,
subgroup 2 (DC resistance only), and subgroup 5 – the following exception shall apply: Resistors shall be inspected without addition
of any coatings to the laser-marked surface area. Resistors shall be examined for legibility under normal production room lighting by
an inspector at 10X magnification, and ppm reporting is not applicable) and group B inspection of MIL-PRF-55342. Additionally; a
power moisture resistance test as specified in 4.5 shall be performed when specified in the PIN.
*
4.4.2 Certification. The manufacturer shall submit a certificate of compliance in lieu of the group B inspection and/or the power
moisture resistance test, if not order in the PIN.
4.5 Short time overload. Resistors shall be tested in accordance with MIL-PRF-55342. The following details and exceptions shall
apply:
*
*
a. An overload dc test potential which will result in 5 times the rated wattage.
4.6 Power 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 used with 0 defects allowed.
4.7 Solder mount integrity. Resistors shall be tested as specified in MIL-PRF-55342 and the following exceptions shall apply.
Force applied 1.8 kilograms.
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 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, CDROM 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. Surface mount resistors are used in electronic circuits where space is a major concern.
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.
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).
