We will introduce a case where ICP measurement was conducted using panels before and after reliability testing, along with quantification. The liquid crystal molecules in an LCD are oriented within the panel, and the display is controlled by changes in the orientation state of the liquid crystal due to voltage. When ionic substances, such as metal elements, are present inside the panel, the liquid crystal does not operate correctly, leading to display defects. Ionic substances are known to increase due to contamination during manufacturing or long-term use, making it important to quantify and understand them as part of panel quality.

Dynamic light scattering allows for the measurement of particle size and size distribution of nanoparticles dispersed in a liquid without separating the particles. Here, we present an example of measuring the particle size of silica and alumina particles in an aqueous medium. Particles in a solution exhibit Brownian motion that depends on their size, and the fluctuations in the scattered light produced when the particles are illuminated depend on their size as well. By observing and analyzing these fluctuations, we can determine the particle size and size distribution.

In ANSI/ESDA/JEDEC JS-002-2014, it is required that the relative humidity near the device during testing be kept below 30%. The verification method involves installing temperature and humidity sensors in two locations near the sample to continuously monitor temperature and humidity, and the test begins when the relative humidity falls below 30%. The AEC standards also explicitly state in the 2019 revision that they comply with ANSI/ESDA/JEDEC JS-002, and it is expected that the demand for low humidity environments will continue to increase in the future. 【Humidity Requirements for Major CDM Test Standards】 ■ ANSI/ESDA/JEDEC JS-002-2018: Relative humidity below 30% ■ AEC-Q100-011 Rev-D・AEC-Q101-005 Rev-A: Relative humidity below 30% ■ JEITA ED-4701/302A (Test Method 305D): Ambient temperature 25°C ± 5°C *For more details, please refer to the PDF document or feel free to contact us.
