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 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.

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.

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

At AITES Co., Ltd., we offer "environmental testing in a high-power constant temperature and humidity chamber." We can achieve a constant temperature change of up to 15°C/min (-45 to ±155°C). Temperature cycle tests can be conducted by controlling the temperature gradient. Additionally, the temperature control range is wider than that of typical constant temperature and humidity chambers, allowing control 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) possible ■ Temperature cycle tests can be conducted by controlling the temperature gradient ■ Wider temperature control range than typical constant temperature and humidity chambers ■ Controllable 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 continuously. 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 this 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 erosion 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.

The RNP-45 is a surface mount power film resistor designed to be compatible with the TO-252 package, weighing only 0.33 grams, with a thermal resistance of 3.0°C/W and a rated power of 45W. The resistive element is a pulse-resistant thick film, featuring excellent high-frequency characteristics with a reactance component of 2.7pF and 14.7nH, while also having a pulse power performance of 1kW-1µs despite its small size. The operating temperature range is from -55 °C to +175 °C. Additionally, it incorporates several design features, such as the removal of the metal flange to maximize the thermal performance of the resistor, compatibility with standard reflow SAC solder joints instead of wire bond connections, making it suitable for automatic mounting, an increased resistive element area to enhance surge performance, and the adoption of a 0.8mm substrate to strengthen bending stress.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

Hotron's vehicle detection sensors allow you to search for products that meet your needs in three categories: "Purpose of Use," "Location of Use," and "Product List." The sensors detect the passage of vehicles, alerting you with rotating lights or switching the display of parking availability. They manage vehicle presence, full parking, and exit warnings in parking lots, contributing to safe driving and smooth operational management within the parking area. They are used in various settings, from coin-operated parking to large-scale parking lots.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
