Strain measurement of power module package resin.

Measuring the strain behavior of the sealing resin under thermal cycling using a strain gauge!

We would like to present the results of strain measurements conducted by attaching strain gauges and thermometers to the surfaces of power modules, both in a mounted state on a circuit board and in an unmounted state. In the mounted module, it was observed that the temperature change was slightly slower, and correspondingly, the change in strain was also slow. This is believed to be due to the delayed transfer of heat to the module when it is mounted. 【Test Overview】 ■ Strain Gauge Used - Foil strain gauge for composite materials: compatible linear expansion coefficient 1x10^-6, base 15x5mm ■ Test Conditions - Hold at -40℃ for 3 hours → 15℃/min → Hold at 80℃ for 3 hours * 5 cycles * For more details, please download the PDF or feel free to contact us.

By applying chemical etching, ion milling, and FIB processing to mechanical polishing, we will analyze various metal joints, starting with lead-free solder.

The joints of electronic components have a significant impact on the overall reliability of the circuit board. Particularly at solder joints, it is important to observe not only the shape but also the metal structure.

It is also possible to estimate the relationship with molecular-level structures! Introducing the types of thermal analysis and the properties that can be understood.

When heat is applied to materials, various properties change. Thermal analysis is suitable for investigating such properties. Depending on the changes in the properties we want to observe, we use different devices and combine them as necessary. By understanding the various changes that occur when materials are subjected to heat, we can gain insights into how they will behave in practical applications. When combined with other chemical analyses, it is also possible to estimate the relationship with molecular-level structures. If you have any questions about the relationship between materials and heat, please feel free to consult us. 【Analysis Equipment (Excerpt)】 <DSC (Differential Scanning Calorimeter)> ■ Changes observed: Heat flow (exothermic/endothermic) ■ Properties that can be determined: Melting point (freezing point), glass transition, crystallization, specific heat capacity ■ Applicable materials: Plastics, rubber, metals ■ Analysis examples: Measurement of the curing degree of thermosetting resins, measurement of the transformation temperature of shape memory alloys *For more details, please refer to the PDF document or feel free to contact us.

Observing the behavior of strain in thermal shock testing! The test materials used are FR-1 and FR-4.

We would like to introduce the "Strain Measurement of Thermal Shock Testing" conducted by our company. A sample with a strain gauge attached was set up in the thermal shock testing device, and the wiring of the strain gauge was connected to an external data logger to record the strain data in real-time during the test. The strain behavior during the thermal shock test was observed for two types of copper-clad laminates, and it was noted that significant strain occurred with changes in temperature. It was found that FR-1 exhibited greater strain compared to FR-4. [Test Conditions] ■ Temperature Cycle: -30°C to 120°C ■ Exposure Time at Each Temperature: 30 min ■ Test Materials - FR-1 Paper Phenolic (Double-sided board) - FR-4 Glass Epoxy (Double-sided board) ■ Strain Gauge: Foil strain gauge for printed circuit boards *For more details, please refer to the PDF document or feel free to contact us.

We investigated the behavior of strain during moisture absorption and drying using a strain gauge!

We would like to introduce the results of our investigation into the behavior of strain during moisture absorption and drying using strain gauges. It was observed that the material expands when absorbing moisture and contracts back to its original state when drying, with the strain returning to the condition prior to moisture absorption. Regarding FR-1, it is presumed that it did not return to its original state due to changes in the chemical structure of the material caused by hydrolysis. 【Test Overview】 ■ 85℃ 50% ⇒ 85℃ 85% ⇒ 85℃ 50% ■ Test Materials ・FR-1 Paper Phenolic (single-sided board) ・FR-4 Glass Epoxy (single-sided board) ■ Strain Gauge ■ Foil Strain Gauge for Composite Materials *For more details, please download the PDF or feel free to contact us.

In civil engineering sites, the use of sheet piling methods is essential for safely utilizing the site, including temporary roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates have been widely used, but due to their weight, they can be cumbersome to transport, install, and remove. Hyper CLT sheet piles are civil engineering materials made from wooden CLT for civil use. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle with small machinery, contributing to reduced burdens during installation and improved work efficiency. They can be utilized in a wide range of civil engineering sites for measures against muddy conditions, ground protection, heavy machinery scaffolding, and ensuring pedestrian pathways. As a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A," it is also recommended as a material for innovative ideas, safety measures, and environmental considerations in public works.
