22、rs 2 General requirements The requirements of this standard include robust qualification tests for the full range of expected commercial applications; so, suppliers can use it to satisfy the requirements of multiple OEM customers. 2.1 Objective The objective of this qualification program is to ensur

23、e that components meet acceptable quality and/or reliability levels. 2.2 Classifications for voltage and temperature range Qualification testing parameters are dictated by the components rated voltage (UR) at rated temperature (TR) and category voltage (UC) at category temperature (TC). Voltage valu

24、es from rated voltage (UR) to category voltage (UC) are derated linearly unless otherwise specified by the manufacturer. 2.2.1 Terms Family: A component family is all electronic components with sufficiently similar manufacturing processes and materials and performance attributes as to be able to be

25、qualified by a single qualification test program. Generic data: Current component test data demonstrated to apply to the component family under test and are reflective of current manufacturing processes and materials. Site: The manufacturing facility used for final assembly of the component. Even if

26、 final testing is at another facility, the final-assembly location shall be considered the site. Rated temperature (TR): The maximum temperature at which the device can be used without voltage derating. It is the same as or lower than the category temperature (TC). Category temperature (TC): The max

27、imum recommended operating temperature of the device. EIA-717-A Surface mount niobium and tantalum capacitor qualification specification Page 6 Rated voltage (UR): The maximum recommended peak DC operating voltage for continuous operation up to the rated temperature (TR). Category voltage (UC): The

28、maximum recommended peak DC operating voltage for continuous operation at the category temperature (TC). In some classes of components there is no voltage derating up to category temperature. Below are common temperature range classifications currently available. Table 1 Common temperature range cla

Qu

32、alification shall be based on specific requirements associated with characteristics of the device and manufacturing process. The qualification requirements, referenced in Table 2, are the same for new products, products with process changes affecting form, fit or function, and products from new site

33、 locations. For each stress test, two or more qualification families can be combined if reasoning for similarity is technically justified, supported by data and periodically reviewed for soundness of original assumptions. To reduce the amount of qualification testing needed, strive to increase avail

34、able generic data thats applicable to more components and families. For example, this can be achieved through qualification and monitoring of the most complex device in the family and applied to less complex devices that subsequently join this family. Generic data shall come from supplier-certified

35、test labs, and can include internal suppliers qualification, user-specific qualifications and suppliers in-process monitors, as long as the test conditions and endpoint test temperatures address the worst case temperature extremes and other conditions defined in this specification. 2.3.2 Qualificati

36、on families In order for tested components to qualify as a family, the qualification must represent the same manufacturing process, materials and formulation. A minimum of four capacitor ratings chosen to represent high and low CV ratings, high and low voltages, and a variety of case sizes shall be

37、tested. There must be valid and obvious links between the data and the subject of qualification. 2.4 Test samples 2.4.1 Production requirements Test samples must be manufactured using the same equipment, process, and site(s) as used for production parts. 2.4.2 Reusability of test samples Devices, wh

38、ich have been used for nondestructive qualification tests may be used to populate other qualification tests except as noted in specific test descriptions. EIA-717-A Surface mount niobium and tantalum capacitor qualification specification Page 7 2.5 Definition of electrical test failure after stressi

39、ng Electrical test failures are defined as those devices not meeting the individual device electrical requirements called out in clause 4 of this document. 3 Qualification 3.1 When qualification is required Qualification is required for: A) New products B) Changes to qualified products that affect t

40、he form, fit, or function C) New site locations. 3.1.1 Qualification of products (A and B) The stress test requirements and corresponding test conditions for the qualification are listed in Table 2. For each qualification, the supplier must present data for all of these tests, either specific to the

41、 device to be qualified or acceptable generic data. Justification for the use of generic data must be demonstrated by the supplier and approved by the user. 3.1.2 Qualification of manufacturing sites (C) For site qualification, each manufacturing location must be qualified separately to prove capabl

42、e of running the required processes. A single-family qualification is sufficient for nonlocation specific materials, processes and design changes. 4 Qualification tests 4.1 General tests Individual samples per tests required in Table 2 are selected from one manufacturing lot of each value being qual

43、ified. A minimum of three manufacturing lots shall be selected for the tests defined in clauses 4.5 to 4.7. All parameters shall be measured at the conditions, e.g., test frequency, voltage, etc., defined in EIA-535 BAAC for MnO2cathode devices and EIA/ECA-953 for polymer cathode devices. Table 2Cap
