Measurement of moisture absorption distortion

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 dried, with the strain returning to the condition prior to moisture absorption. Regarding FR-1, it is presumed that the material did not return to its original state due to changes in its chemical structure 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.

Introducing a case study of measuring Poisson's ratio using a tensile testing machine and strain gauges!

We would like to introduce the Poisson's ratio measurement conducted by our company. Poisson's ratio is the ratio of longitudinal strain to lateral strain that occurs when a load is applied to an object, and it is necessary for strength calculations of materials. We can accommodate Poisson's ratio measurements and strength measurements through tensile testing. Please feel free to consult with us. 【Measurement Examples】 ■ Measurements using a tensile testing machine ■ Strain measurement results and Poisson's ratio calculation results *For more details, please refer to the PDF materials or feel free to contact us.

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

We would like to introduce the "strain measurement in 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 strain data in real-time during the test. For two types of copper-clad laminates, the strain behavior during the thermal shock test was observed, and it was noted that significant strain occurred with temperature changes. 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) - FR-4 Glass Epoxy (double-sided) ■ Strain Gauge: Foil strain gauge for printed circuit boards *For more details, please refer to the PDF document or feel free to contact us.

Two high-power constant temperature and humidity chambers have been introduced! Ideal for temperature cycle tests and temperature and humidity cycle tests for automotive components and more.

At AITES Co., Ltd., we offer "environmental testing in a high-power constant temperature and humidity chamber." It is capable of a constant temperature change of up to 15°C/min (-45 to ±155°C). Temperature cycle testing can be conducted by controlling the temperature gradient. Additionally, the temperature control range is wider than that of typical constant temperature and humidity chambers, with control possible at 95°C. 【Features】 ■ Two high-power constant temperature and humidity chambers introduced ■ Constant temperature change of up to 15°C/min (-45 to ±155°C) is possible ■ Temperature cycle testing can be conducted by controlling the temperature gradient ■ Temperature control range is wider than that of typical constant temperature and humidity chambers ■ Control possible at 95°C *For more details, please refer to the PDF materials or feel free to contact us.

Applicable to change observation, with support for additional analysis! We evaluate the subject in a time series and non-destructive manner.

During reliability testing, the samples change moment by moment. Do you have any questions such as "At what point did the crack occur?", "How does the degradation progress?", or "How much has it changed from the initial state?" By combining it with reliability testing, we will evaluate the subject in a time-series and non-destructive manner. 【Features】 ■ Applicable for observing changes in whiskers, migration, pressure resistance, solder evaluation, chemical corrosion tests, and aging products in the market ■ Environmental tests and observation frequency will be conducted according to customer requirements ■ Additional analyses such as electrical characteristics, SEM observation, elemental analysis, and cross-sectional observation are also available *For more details, please refer to the PDF document or feel free to contact us.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily visible at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

PERI products are used at construction sites around the world. This time, we would like to introduce the construction work of the "Dunajec Road Bridge" spanning the Dunajec River in the town of Nowy Targ in southern Poland. The road bridge was planned to be constructed using a balanced cantilever method, dividing the cantilever beams starting from each pier into 10 segments. A particular concern was to strictly adhere to the concrete pouring cycle for each segment. To achieve this, a balanced cantilever carriage (VBC) equipped with a hydraulic advance system and an automatic formwork stripping function was adopted. By utilizing the VBC, it became possible to pour concrete for segments up to a maximum length of 5 meters in a single cycle, allowing for efficient and timely construction. PERI products: 1. TRIO Panel Formwork 2. VARIO GT24 Wall Formwork 3. PERI UP Flex Modular Scaffold 4. VST Heavy-Duty Shoring Tower PERI Japan Co., Ltd.
