EMTs has a variety of equipment to perform its own reliability tests for supplying more reliable products to the customers.
Thermostatic Chamber
Model
TH-KE-100
Purpose
Temperature tolerance test of main boards and systems
To keep them in a thermostatic chamber at -40℃ for 48 hours and then perform a low temperature booting test on whether or not to be normally booted and operated at the cold environment condition.
To test on whether or not the main boards and systems are normally operated at 60~80℃ and the 90% humidity.
Standards
Test available between -40℃ and 150℃
Application Cases
Low Temperature Booting Test
High Temperature/Humidity Operation Test
ESD Simulator
Model
NOISEKEN ESS-S3011A
Purpose
ESD simulator, ESD testing for main boards and systems
Standards
Output Voltage
0.2 ~ 30.0kV +/- 5 % (Max. 30.5kV)
0.2 to 10kV: 0.05V step, 10.0 to 30.0kV: 0.1kV step 0.2~10kV : 0.05V step, 10.0~30.0kV : 0.1kV step
The main boards must be designed to give off heat without any effect on circuit performance and cost.
The technical development of infrared thermography enables us to see with the eyes and quantify heat patterns by board shape and component layout.
In order to secure reliability as well as general operation test in the mainboard development stage, we check component’s heat generation caused by the long use and minimize the errors due to component deterioration caused by heat, which achieves the long-term MTBF.
Standards
Temperature measurement range: -20℃ to 650℃ (Accuracy ±2 degree)
Application Cases of Thermal Imaging Camera
The board’s heat distribution checked before designing a radiator is reflected in cooling design.

Long Run Aging Test (Programmable Auto Power On/Off Test)
Long Run Aging Test System
Operation Software for Long Run Aging Test
EMTs’ self-developed Long Run Aging System Long Run Aging System (Programmable Auto Power On/Off Hardware & Software)
Purpose
Long run test & power on/off test for development products
Composition
It consists of self-developed long run aging system (hardware), operation software run by separate PC connected with a network and counterprograms installed in each individual test equipment.
On/Off testing is performed by setting a total of 5-step variable on/off time conditions and testing numbers in an operation software.
The testing numbers set in an operation software and the count of normal booting in the test equipment are compared and checked through counterprograms installed each test equipment.
In case of general manual/mechanical power on/off testing, the repetitive tests can be done under the only one appointed time condition among 3 minutes, 5 minutes or 10 minutes. However, such repetitive tests by this equipment can be done under each different time condition through 5-step variable time settings. Therefore, for the long-term testing for life prediction of development board, you need to check the final count only without continuous checking if each booting is normal.
In case of power on/off testing, 8 pieces of equipment can be tested through one operation software. The number of equipment to be tested can be continuously extended by a multiple of 8 such as 16, 24, 32, 40 units according to the configuration of the test system.
The board’s heat distribution checked before designing a radiator is reflected in cooling design.
