Electronic Restoration >> Water Damage Electronic Restoration Classes

When candidate plug or receptacle D-subminiature, microminiature or printed circuit connectors are submitted for qualification, completely assembled mated pairs shall be used. Connectors shall have a full complement of contacts. For Level 1 qualification, three mated pairs shall be prepared. For Level2 qualification, Water Damage Electronic Restoration Classes two mated pairs shall be prepared. 

Connectors may be mated and demated as required for completion of testing.8/ For Level 1 qualification of radio frequency connectors, six samples shall be prepared with mating connectors. The six samples shall be divided into twogroups. Group A shall consist of four samples Water Damage Electronic Restoration Classes and Group B shall consist of two samples. 

For Level 2 qualification, two samples shall be prepared withmating connectors, and shall be submitted for the tests as designated. Connectors may be mated and demated as required for completion of testing. 9/ For Level 1 qualification of plug-in sockets, six samples are required. Some tests require all six samples to be tested, Water Damage Electronic Restoration Classes after which, the samples shall bedivided into two groups, 1 group of four and one group of two, for further testing. 

For Level 2 qualification, two samples shall be submitted for testing.10/ For filter pin connectors, two samples designated A & B shall be subjected to qualification. Both samples shall be subjected to the tests where a quantityof two is required. For Level 1 qualification, Water Damage Electronic Restoration Classes sample A shall be subjected to vibration and shock testing, and sample B shall be subjected to solder ability and mating/unmating force testing.11/ 

For qualification of contacts, contact sample quantity shall be divided into groups A through D for Level 1 qualification and groups A & B for Level 2.12/ For coaxial contacts, Water Damage Electronic Restoration Classes engagement force shall not exceed 24 ounces, and separation force shall not be less than 3 ounces, or as otherwise specified. 

Connectors of all types/styles are derated by limiting the voltage stress placed on the dielectricmaterial, and by limiting the current flow Water Damage Electronic Restoration Classes and consequent temperature rise due to the effects ofresistive heating across mated contacts within the dielectric insert. Example: MIL-DTL-38999 series I connectors have a DWV test voltage of 1300VAC. 

They also have a suggestedoperating (working) voltage of 400VAC at sea level. Derated voltage would be 25% of 1300VAC (325VAC) or75% of 400VAC (300VAC). Either value is acceptable.2/ For printed circuit connectors, Water Damage Electronic Restoration Classes apply derating based on the contact size vs. the equivalent wire size in section W1,table 4A, for bundled cable. 

Example, as a minimum, a size 20 contact shall be derated the same as a 20 AWGwire used in a bundled cable assembly. MIL-PRF-3098, Crystal Units, Quartz, General Specification for, Water Damage Electronic Restoration Classes has no provision for radiation hardness. If radiation hardness is a requirement for thesuccess of the mission, parts must be procured to a specification control drawing (SCD) that includes the requirement for radiation testing to the specifiedtotal dose. 

Also, only parts using at least a three point mount shall be used.3/ Any test required by Tables 2 and 3 that is already performed by the procurement specification (military or SCD) need not be repeated. However, Water Damage Electronic Restoration Classes lotspecific attributes data for screening tests, and lot specific or generic attributes data as applicable to various test groups of qualification tests must besubmitted to show that tests were performed with acceptable results.4/ 

MIL-PRF-3098 does not require 100% conformance testing of all parts in a lot. Also, the specification does not require PIND testing. Therefore, Water Damage Electronic Restoration Classes all partsprocured to a MIL-PRF-3098 part number must be screened to the requirements of Table 2 before use in a Level 1 application unless lot specific attributesdata is obtained from the manufacturer.5/ 

All SCDs must be written in accordance with the requirements of MIL-PRF-3098, Tables 2 and 3 of this section, and contain the following design Water Damage Electronic Restoration Classes requirements: crystals shall be swept synthetic quartz meeting the infrared quality requirements of grade A or B of IEC60758; and shall be mounted withat least a three point mount. 

The full title of the IEC document is Synthetic Quartz Crystal Specifications and Water Damage Electronic Restoration Classes Guide to the Use, IEC60758(1993-04),International Electrotechnical Commission, Geneva, Switzerland.5.1/ The IEC specification lists six levels of infrared quality, which are designated from Aa (the best) to E (the worst). 

A and B are the levels that severalprominent oscillator manufacturers recommend for space Water Damage Electronic Restoration Classes and military applications. Infrared quality is an indirect measure of the level of impurities in acrystal. Impurities can affect frequency aging characteristics6/ For miniature surface mount crystals in hermetic packages, a model for an SCD may be found in DSCC Drawings 94023 or 94024, issued by the Defense Supply Center, Columbus, Ohio.  

It is the responsibility of the user to specify detailed test conditions and define pass/fail criteria for each test. These values shall be based on the nearestequivalent military specifications, Water Damage Electronic Restoration Classes the manufacturer's specification, or the application, whichever is more severe.2/ Except for internal visual inspection, screening will be performed on all parts in the lot.3/ 

In lieu of interval visual, DPA shall be performed to the requirements of S-311-M-70 specification.4/ Pure Tin finish is prohibited as a final finish on EEE parts. Any oscillator, Water Damage Electronic Restoration Classes which is procured to a MIL-PRF-55310 detail specification (i.e., "slash sheet"), an existing SCD, or as a manufacturer's standard catalog part, must be evaluated or tested to determine it ability to meet the Total Ionizing Dose (TID) and Single Event Upset (SEU) requirements of the mission.2/ 

Custom crystal oscillators, which employ hybrid microcircuit construction techniques, Water Damage Electronic Restoration Classes shall satisfy the element evaluation requirements of Section M2herein. This requirement does not apply to oscillators that are standard parts available in a manufacturer's catalog.3/ Any test required by Tables 2 and 3 that is already performed by the procurement specification (military or SCD) need not be repeated. 

However, Water Damage Electronic Restoration Classes lotspecific attributes data for screening tests, and lot specific or generic attributes data as applicable to various test groups of qualification tests must be submitted to show that tests were performed with acceptable results.4/ MIL-PRF-55310, Oscillator, Crystal Controlled, General Specification for.5/ 

Class B crystal oscillators are acceptable as Level 1 parts only when Class S oscillators are not available.6/ An SCD must be written in accordance with the Water Damage Electronic Restoration Classes requirements of MIL-PRF-55310 and contain the following design requirements:
