HAST Chamber Highly Accelerated Stress Test Chambers

HAST (Highly Accelerated Stress Test) chambers reduce the time it takes to complete humidity testing for semiconductors. By elevating temperatures above 100°C and increasing the pressure, simulation of normal humidity tests can be made while maintaining the same failure mechanisms. Tests can be completed in days, or weeks. Our HAST systems have a modern design that's easier to use.

1,Automatic humidity filling

2,Automatic door lock

3,A round workspace,allowing wider sample boards to be loaded

4,Convenient,hermetic power-pin system for bias testing

We now offer and "Air HAST" modification for faster testing of lead-free solder whisker resistance to humidity.

1.Air-circulating fan for high-accuracy testing

  The air-circulating fan minimizes variations in temperature and humidity in the test area for greater accuracy during testing. The fan enables uniform stress to be applied to a specimen.

2.Maximized workspace

  The cylindrical pressure vessel distributes pressure evenly and offers soperior strength. Interior is expanded for easier loading of a large specimen such as printed circuit board.

 3.Prevention of dew condensation and wetting of specimens

  Compared with natural convection test systems,the double cylindrical structure and proprietary air-conditioning system prevents dew condensation and water droplets falling on the specimen.Temperature control and operation of the test area fan before and after testing also prevents dew condensations and droplets from forming on samples,ensuring highly readable testing results.(Featuring dry and wet-bulb temperature control and unsaturated control)

 4.Color coding for easy connection

  Specimen signal terminals with 12 powerpins per unit is equipped as standard.Additional 12 pins per set are available as optional and can be expanded up to total 72 pins.Complicated connection ork is also made casier thanks to color-coded terminal(black=negative,red=positive).

 5.Specimen protection from risk of damage

  A specimen poer supply control terminal is equipped as one of safety features,which output contact signals to allow voltage and signals to be applied to the specimen during testing.In the case of activation of safety devices such as overheat protection and boil-dry

protection,any externally powered devices can be also turned off with this terminal to avoid the risk of damage to the specimen or the chamber.

7-inch color LCD touch panel

1.Color LCD touch panel

  The Resistive Touch Panel procides versatility by allowing users to use gloves,wet hands,nails and stylus to interact ith the panel.

2.Multilingual support

  You can select the display language from English/Chinese(Simplified/Traditional)/Korean and the changes take effect immediately without a system reboot.

3.Temperature,humidity and pressure graph display function

  The Trend-Graph Display Function allows users to monitor the temperature,humidity,and pressure* conditions in the test area,in a graph.

  *Pressure monitoring function or recorder option is required.

4.Pressure monitoring function(option)

  The pressure can be displayed on the screen or can be read via the Ethernet,RS-485(option)or RS-232C (option).Monitored value on the screen can be sitched between humidity and pressure.

5.Auto-locking mechanism

  Door lock safety mechanism to prevent opening of the door while the chamber is pressurized.

6.Automatic humidity filling

  The humidfying ater is filled from the built-in water supply tank at the start of a test automatically.

  The water level in a tank can be checked from outside through the slits on the front cover.

  Bottom or the unit allows storage space for power supply unit and peripheral equipment.

7.No pressure or temperature shock after testing prevents specimens from drying put

  Gradual depressurization and air/water drainage mechanisms eliminate sudden changes in pressure and temperature after testing is completed,thus ensuring moisture contained in the specimen does not evaporate.This procides more accurate test results in correlation to the field.

Control functions that make use of convention test data

 The control functions can be selected from dry&wet-bulb temperature control,unsaturated control,and wet-saturated control according to the conventional test data.

 With the addition of Air-HAST mode,four different types of testing can be performed on one chamber.

 2.Three modes of operation control

 *The temperature and humidity fradient before and after testing can be controlled.

 *After testing is complete and chamber pressure reaches 0.010MPa(Gauge),only air is discharged;hunidifying water is retained. 

 *In the hold process,temperature and humidity inside the chanber are maintained at the specified level.(+50 to +95℃/75 to 95%rh)

*During temperatureheat-up when condensation can easily occur on the specimen,the temperature of the humidifying water automatically increases while keeping it 30℃ lower than the chamber temperature.

*After testing is complete,the chamber is left to cool and depressurize naturally untill chamber pressure reaches 0.010MPa(Gauge).Then both air and water are discharged.

*Chamber temperature is controlled through a humidifying heater.(chamber temperature=humidifying water temperature)

 *After testing is compelete,the chamber is left to cool and depressurize naturally until chamber pressure reaches 0.010MPa(Gauge).Then only air is discharged;humidifying water is retained.

Reproduction of near-constant temperature and humidity testing environment with Air-Hast(option)

 1. Air-HAST function

  Depending on the specimen,not only wter steam but also oxidation and other specimen surface conditions can cause failure.

  By leaving air in the test area,the Air-HAST function adds air to the high-temp,high-humidity,and pressurized environment for effective accelerated testing of specimens of specimens for which the oxygen in air affects degradation,such as with surface oxidation.(Accerleration may not be seen for some specimen.)

 2.Whisker humidity-resistance evaluation testing(Japanese patent No.5066143)

  Evaluation examples for whisker evaluations of mounting boards are limited.One of the main reasons for this is because the testing time can be as long as 1000 or 3000 hours.

To shorten these testing times,GRANDE conducts lead-free solder whisker evaluation of mounting boards using Air-HAST.The result confirmed accelerated effects with testing at 85℃and 85%rh humidity.

Easy customization with various options

1.Electro-chemical migration evaluation

  Integration with an GRANDE Electrochemical migration evaluation system(sold separately)enables more accurate measurements.

2.High-voltage,high-current compatibility

  To meet application purposes and goals,ESPEC offers optional high-volatage(1000V AC/DC,1A)/ high-current(125V AC/DC,10A) specimen signal terminals in addition to the standrd specifications(125V AC/DC,1A).

3.Terminal block to increase productivity

  Using the slide shelf terminal block (option),the terminal block can be pulled forard from inside the test area to fcilitate wiring work.

  In addition,removable 12-channel terminal blocks(option)can be added inside the chamber.This reduces the time required for installation and wiring for greater work efficiency.

4.Safety enhancement functions available

  Optional emergency stop switches and status indicator ;ights are available.

5.International standards

  Complies ith the following standards:

  ISO 12100 Safety of Machinery

  ICE 60204 Low Voltage

  ICE 61000-6-2 EMC

  ICE 61000-6-4 EMC

  RoHS Directive

Conforms to international IEC 60068-2-66 standard

1.Temperature and humidity control for support of vaarious test standards

  With GRANDE’s unique wet and dry bulb temperature control on chamber,temperature and humidity are measured directly using a wet and dry bulb temperature sensor.This ensures highly precise temperature and humidity control over the entire testing process,from before testing to the post-testing temperature decrease or hold

process.After testing is complete,the temperature and humidity are allowed to drop for a fixed period. In the hold process,the chamber is kept at a fixed environment until the door is opened and specimens are removed.This makes it possible to place a specimen in a constantly controlled temperature/humidity environment,and keep it from drying fter returning to atmospheric pressure.

2.IEC 60068-2-66,an environmental testing standard of the IEC(International Electrotechnical Commission)

  The Highly Accelerated Stress Test Syetem uses GRANDE’s unique dry and wet-bulb temperature control to satisfy the test system conditions and test operations specified in the IEC 60068-2-66 standard.

 *GRANDE was directly involved in drawing up the IEC 60068-2-66 standard,and our technical concepts and meaasurement data were used in its development.
