halt testing the goal of the accelerated-stress techniques used by datel is to force device maturity, in a short period of time, by exposing devices to excessive levels of "every stimulus of potential value." we use halt (highly acceler- ated life testing) repeatedly during the design and early manufacturing phases to detect potential electrical and mechanical design weaknesses that could result in possible future ? eld failures. during halt, prototype and pre-production dc/dc converters are sub- jected to progressively higher stress levels induced by thermal cycling, rate of temperature change, vibration, power cycling, product-speci? c stresses (such as dc voltage variation) and combined environments. the stresses are not meant to simulate ? eld environments but to expose any weaknesses in a product?s electro/mechanical design and/or assembly processes. the goal of halt is to make products fail so that device weak- nesses can be analyzed and strengthened as appropriate. applied stresses are continually stepped up until products eventually fail. after corrective actions and/or design changes, stresses are stepped up again and the cycle is repeated until the "fundamental limit of the technology" is determined. datel has invested in a qualmark ovs-1 halt tester capable of applying voltage and temperature extremes as well as 6-axis, linear and rotational, random vibration. a typical halt pro? le (shown above) consists of thermal cycling (?55 to +125c, 30c/minute) and simultaneous, gradually increas- ing, random longitudinal and rotational vibration up to 20g?s with load cycling and applied-voltage extremes added as desired. many devices in datel?s new a-series could not be made to fail prior to reaching either the limits of the halt chamber or some previously known physical limit of the device. we also use the halt chamber and its ability to rapidly cool devices to verify their "cold-start" capabilities. quali cation for each new product, electrical performance is veri? ed via a comprehen- sive characterization process and long-term reliability is con? rmed via a rigorous quali? cation procedure. the qual procedure includes such strenu- ous tests as thermal shock and 500 hour life. qual testing is summarized below. in-line process controls and screening a combination of statistical sampling and 100% inspection techniques keeps our assembly line under constant control. parameters such as solder-paste thickness, component placement, cleanliness, etc. are statisti- cally sampled, charted and ? ne tuned as necessary. visual inspections are performed by trained operators after pick-and-place, soldering and cleaning operations. units are 100% electrically tested prior to potting. all devices are temperature cycled, burned-in, hi-pot tested and ? nal-electrical tested prior to external visual examination, packing and shipping. rapid response to problems datel employs an outstanding corrective-action system to immediately address any detected shortcomings in either products or processes. when- ever our assembly, quality or engineering personnel spot a product/process problem, or if a product is returned with a potential defect, we immediately perform a detailed failure analysis and, if necessary, undertake corrective actions. over time, this system has helped re? ne our assembly operation to yield one of the lowest product defect rates in the industry. typical halt pro le quali cation test method/comments halt datel in-house procedure high temperature storage max. rated temp., 1,000 hours thermal shock 10 cycles, ?55 to +125c temperature/humidity +85c, 85% humidity, 48 hours lead integrity datel in-house procedure life test +70c, 500 hours* marking permanency datel in-house procedure end point electrical tests per product speci? cation quali cation testing * interim electrical test at 200 hours. 10 20 30 40 50 60 70 80 90 40 20 0 random vibration (g's) temperature (c) test time (minutes) 100 80 60 40 20 0 ?20 ?40 uwr series single output, high reliability, 2" x 1", 6-10 watt, dc/dc converters mdc_uwr6-10w series.b05 page 6 of 6 www.murata-ps.com/support murata power solutions, inc. makes no representation that the use of its products in the circuits described herein, or the use of other technical information contained herein, will not infringe upon existing or future patent rights. the descriptions contained her ein do not imply the granting of licenses to make, use, or sell equipment constructed in accordance therewith. speci? cations are subject to cha nge without notice. ? 2012 murata power solutions, inc. murata power solutions, inc. 11 cabot boulevard, mans? eld, ma 02048-1151 u.s.a. iso 9001 and 14001 registered this product is subject to the following operating requirements and the life and safety critical application sales policy : refer to: http://www.murata-ps.com/requirements/
