Are you having trouble with brightness degradation evaluation? We propose a simple comparative assessment.
We offer a "Simple Sulfide Discoloration Comparison Experiment Service" for evaluating the sulfide discoloration of silver-plated materials. In the case of LED lighting, the degradation of brightness due to factors such as the inner surface of the package, particularly the silver-plated surface, becomes a concern. This issue is unavoidable for outdoor lighting applications where the impact of sulfide on the silver-plated surface cannot be ignored. Similar problems may also arise in infrared centers depending on the application. It is possible to evaluate the discoloration of silver plating on packaged materials and to easily assess the gas barrier properties of the materials used. 【Service Examples】 ■ Storing reference and evaluation samples together in a wide-mouth bottle to observe changes over time ■ Evaluating gas barrier properties through comparison of discoloration on the silver-plated surface

Company information
We assist those involved in the research and development of semiconductor devices and related materials as their hands and feet in solving problems. (1) Problem-Solving Support Services Research and development itself is the main theme of problem-solving. We leverage our experience from over 10,000 related prototypes to conduct investigations, analyses, and propose experiments. (2) Electronic Component Processing Services Especially for sensors, there are many irregular shapes that are difficult to accommodate with dedicated equipment. In cases of small quantities, investment balance can be an issue that prevents starting. We can propose production with minimal investment based on our experience in prototype support. We also provide support for small quantities until customers establish dedicated lines. (3) Prototype-Related Tool and Equipment Development Services At the beginning of semiconductor-related material development, there is a need to create devices and tools for functional evaluation. In most cases, dedicated evaluation devices exist, but they are multifunctional and expensive. You can utilize our services when a simple device for single-function comparative evaluation is needed in the early stages of development. We have a track record for applications such as sheet-related materials, package resins, encapsulation resins, phosphors, and QDs.
