King Son Instrument Tech. Co., Ltd.
King Son is ready now and starts to deliver the outstanding King Son test chambers and solutions for electric vehicles and automotive electronics industry to conduct reliability testing with efficiency performance.
According to the latest electric vehicle testing regulations and international testing standards, the testing requirements for surface temperature detection and temperature cycle temperature change rate of testing specimens have become a prominent reliability testing technology trend.
King Son's environmental testing chambers that meet the requirements of international testing standards is designed in with surface temperature detection and temperature cycle temperature change rate by testing specimens to conduct product's liability testing.
King Son 's Advanced Series THS, TSC, ATSK, HAST+ testing chambers leads the industry with superior technology.
The specific requirements by international testing standards on the surface temperature control of testing specimens include JESD22-A104F, IPC9701, IEC60068-2-14, IEC60068-3-5.
THE SURFACE TEMPERATURE DETECTION OF THE SPECIMENS (DUV, DEVICE UNDER TEST) AND APPLICATIONS
The surface temperature detection module is designed and incorporated with 8-channel temperature sensor to record the testing curve to replace the traditional 2-channel temperature sensor and surpass the industry level, which is more conducive to discover hot spots and temperature changes at various points in experiment test.
The 8-channel temperature sensor is attached to the surface of the specimens, which can be applied to the testing process such as high temperature and high humidity test, dew (condensation) test, temperature and humidity combination test, slow temperature cycle test, etc., that measure the surface temperature or internal temperature of the specimens.
The surface temperature detection module can measure, record and consolidate the setting conditions, actual testing temperature and humidity, and the surface temperature of the specimens together into a synchronous testing curve file for subsequent analysis and storage.
When the surface temperature of the specimens (DUV, device under test) reaches the temperature of the testing condition, the Chamber starts humidification on the surface of the specimens until it is higher than the dew point temperature to ensure that specimens does not condense during test.
Pre-alert and alarm for over-temperature of the specimens (DUV, device under test)
To protect the specimens (DUV, device under test) free from overheating damages, the Chamber is designed with the upper limit temperature warning function and configured with an overheating protector as the standard feature.
THE CHAMBER IS DESIGNED TO CONDUCT CONDENSATION & HUMIDITY FREEZING TEST FOR OUTDOOR ELECTRONIC PRODUCTS AND AUTOMOTIVE ELECTRONICS.
In addition to the fixed-point temperature and humidity test, King Son THS Constant Temperature and Humidity Chamber can conduct the condensation and humidity freezing test required by outdoor electronic products and automotive electronics, that the condensation occurs on the surface of the specimens (DUV, device under test) and simulate outdoor condensation phenomenon, thru that to evaluate material capacity to prevent water vapor diffusion, humidity freezing test to accelerate product resistance to deterioration.
The latest new testing requirements for the dwell time of testing specimens is when the internal temperature of DUT, Devices Under Test, reaches the set temperature and stabilizes that.
Temperature cycle testing standards and temperature change control is based on the surface temperature of the specimens (DUT, Device Under Test) JEDEC-22A-104F、IEC60749-25、IPC9701、ISO16750、AEC-Q100、LV124、GMW3172
Conduct the temperature cycle test by the feature of surface temperature control of the specimens.
2. Dual modes, available to select the heating and cooling temperature change rate.
3. The temperature change rate can be setup by choosing either Total temperature change time or Temperature change rate per minute to set the heating and cooling rate for the testing specimens.
*Total temperature change time (minute) complying with international testing standards JESD22-A104F、MIL-STD-883K、CR200315、ED-4702A.
*Temperature change rate per minute (℃/minute) complying with international testing standards IEC 60749、IPC-9701、Bellcore-GR-468、MIL-2164.
4. The reciprocal of the dwell time can be determined by the surface temperature of the specimens.
5. The number of channels used to control the surface temperature of the specimen: 8 channels.
