Resistor networks are used in surface mounting applications where space is a major concer
32、n. 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
33、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. 6.3 Electrostatic charge. Under several combinations of conditions, these resistors can b
34、e 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. Provided by IHSNot for Resale

The use of alloys with tin content greater than 97 percent, by mass, may exhibit tin whisker growth proble
36、ms 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
37、 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). 6.5 User of record.
