ESS Rapid Temperature Change Stress Screening Machine
Environmental Stress Screening (ESS)
Stress screening is the use of acceleration techniques and environmental stress under the design strength limit, such as: burn in, temperature cycling, random vibration, power cycle... By accelerating the stress, the potential defects in the product emerge [potential parts material defects, design defects, process defects, process defects], and eliminate electronic or mechanical residual stress, as well as eliminate stray capacitors between multi-layer circuit boards, the early death stage of the product in the bath curve is removed and repaired in advance, so that the product through moderate screening, Save the normal period and decline period of the bathtub curve to avoid the product in the process of use, the test of environmental stress sometimes lead to failure, resulting in unnecessary losses. Although the use of ESS stress screening will increase the cost and time, for improving the product delivery yield and reduce the number of repairs, there is a significant effect, but for the total cost will be reduced. In addition, customer trust will also be improved, generally for electronic parts of the stress screening methods are pre-burning, temperature cycle, high temperature, low temperature, PCB printed circuit board stress screening method is temperature cycle, for the electronic cost of the stress screening is: Power pre-burning, temperature cycling, random vibration, in addition to the stress screen itself is a process stage, rather than a test, screening is 100% of the product procedure.

Semiconductor Limit Temperature Detection Scheme (Thermal Shock Test Chamber)
At present, many semiconductor devices must work in various harsh environments such as high and low temperatures for a long time, and the problem of high and low temperature failure is becoming more and more serious. In order to solve the problem of high and low temperature failure of discrete components, the electrical characteristics of devices and the variation of various parameters with temperature under low temperature environment are studied. Therefore, the setting and maintenance of high and low temperature environment is very important for semiconductor devices, which directly affects the feasibility of its normal operation and the accuracy of data. As a fast and accurate temperature control high and low temperature shock system, compared with the traditional temperature control test chamber, dragon temperature forcing system--Froilabo can test the temperature cycle of semiconductor devices or high and low temperature shock, and the temperature rising and dropping rate is very fast, such as temperature from -55℃ to +125℃ can be achieved in only 7s, and the temperature shock test can be carried out on the local area of the test sample without affecting other areas. And the temperature experiment can be carried out on the IC on the load board of test machine platform. Therefore, by using the Froilabo thermal shock system, it is perfectly possible to conduct temperature control tests on semiconductor discrete devices, investigate their ability to withstand extreme high and low temperatures, and the impact of alternating changes in extreme high temperature and extreme low temperature on the device.
Headquartered in Lyon, France, Froilabo has a history of more than 100 years and is a famous French manufacturer of temperature control equipment. Froilabo is a fast, precise temperature control of thermal shock system, its temperature control range is from -80℃ to 250℃. And its applicable fields cover defense industry, aviation industry, military industry, automation components, automotive parts, electronic and electrical instrumentation components, electrical products, plastic, chemical industry, food industry, BGA, PCB substrate, electronic chip IC, and semiconductor ceramic magnetic pharmaceutical industry. By using Froilabo thermal shock system, electronic components and materials can be thermally tested and characterized to improve their reliability, and the method is very simple to apply.
