Highly Accelerated Stress Test System (HAST Chamber)

Highly Accelerated Stress Test System(HAST Chamber)CAT.NO.E96160-X702

Creates temperature, humidity,and pressure environments toIEC60068-2-66 standard.Humidity resistance evaluation tests for electronic componentsCustomers require test results that correlate accurately tothose from the field in a minimal amount of time.The Highly Accelerated Stress Test Chamber EHS Seriesoffer high performance, functionality and ease of use,and are compliant with the international IEC60068-2-66 standard.Many convenient functions and safety features are included for bias testing.

UtilityEven greater convenience and safety.Easy program settingProgram capacity of 10 patterns with 30steps per pattern. Simple operation usingup and down keys for program setting,as well as adjustment of temperature,humidity and time values.Safe and reliable doorThe system employs a button operatedautomatic door locking mechanism.It prevents the door from being openedwhile the test chamber is pressurized.Automatic humidifyingwater supply systemAt the start of testing, the humidifyingwater needed for that test is automaticallytaken from a water tank. A slit onthe front side allows the remainingamount of water in the tank to bechecked at a glance.Protection measures forspecimenStandard equipment includes a specimenpower supply control terminal, whichoutput contact signals to allow voltageand signals to be applied to thespecimen during testing. When aproblem occurs, specimens and chamberare fully protected. Power supply to thespecimen is halted, and protectionmechanisms for preventing overheatingand boil-dry are activated.Instrumentation panelSupports anxiety-free useA variety of protective mechanismsinclude; overheat/overpressure protector,boil-dry protector, detection of watersupply failure and incomplete door-lock,leakage breaker, and temperature sensordisconnection protector. The system alsoemploys an external alarm terminal withan alarm buzzer and lamp. When aproblem occurs, those in the vicinity areimmediately warned.The bottom of the unit includes a water tank and storage spacefor a power supply unit or peripheral equipment.

Control operationComplies with IEC60068-2-66 standard testing while maintainingcompatibility with conventional test methodsConforms to international IEC60068-2-66 standardIEC60068-2-66 is an environmental testing standard of the IEC(International Electro-technical Commission). With ESPEC'sunique wet and dry bulb temperature control function, the EHSSeries meets all requirements for test equipment and testoperation specified in IEC60068-2-66.The EHS Series can also satisfy other test conditions of EIAJED4701, JEDEC and EIA/ JESD22-A110-A as well as IEC.* ESPEC was directly involved in drawing up the IEC60068-2-66 standard, and ourtechnical concepts and measurement data were used in its development.Evaluation of ion migrationWet and dry bulb temperaturecontrol (M type) conforms toIEC60068-2-66 standardWith ESPEC's unique wet and dry bulbtemperature control on M type chamber,temperature and humidity are measureddirectly using a wet and dry bulbtemperature sensor. This ensures highlyprecise temperature and humiditycontrol over the entire testing process,from before testing to the post-testingtemperature decrease or hold process.After testing is complete, the temperatureand humidity are allowed to dropfor a fixed period. In the hold process,the chamber is kept at a fixedenvironment until the door is openedand specimens are removed. This makesit possible to place a specimen in aconstantly controlled temperature/humidityenvironment, and keep it fromdrying after returning to atmosphericpressure.Free from pressure andtemperature shock anddrying of specimens after testExample of the Highly accelerated stress test system with the Ion migration evaluation systemIn all control modes, abrupt changes inpressure and temperature after testinghave been eliminated through mechanismsfor gradual depressurization, andair/water discharge. This preventsvaporization of moisture contained inthe specimen, and provide accurate testresults in correlation to the field.
