Strain measurement in thermal shock testing.

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.

• Non-destructive testing

Not only the joints of electronic components, but also the evaluation of fixed parts such as screws!

At AITES Co., Ltd., we conduct "Thermal Shock Testing." By repeatedly exposing samples to high and low temperatures, stress is generated not only from the thermal effects of high and low temperatures but also from the expansion and contraction of various parts. Repeated stress also adds to the overall stress. This test is conducted not only for the joints of electronic components but also for evaluating fixed points such as screws. 【Main Specifications of the Thermal Shock Testing Equipment】 ■ Internal Dimensions: W650×H460×D370mm Temperature Range: -65 to 0/+60 to 200℃ ■ Internal Dimensions: W650×H460×D670mm Temperature Range: -65 to 0/+60 to 200℃ ■ Internal Dimensions: W970×H460×D670mm Temperature Range: -65 to 0/+60 to 200℃ *For more details, please refer to the PDF document or feel free to contact us.

• Measurement and Analysis Equipment

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.

In-Situ Continuous Measurement Reliability Evaluation Testing Service

In-situ continuous measurement reliability evaluation tests involve applying stress while measuring characteristics to conduct reliability assessments. ● Accurate understanding of failure time is possible In a readout method where samples are taken out from a stress environment at fixed times, failure can only be understood at the timing of the readout, making it impossible to know the exact time of failure occurrence. In-situ measurement allows for accurate understanding of failure time. ● Detection of recoverable failures is possible Recoverable failures can cause significant issues in the market. In most cases, these recoverable failures cannot be detected using the readout method, but in-situ measurement allows for the detection of recoverable failures, enabling accurate judgment and assessment. ● Monitoring of stress application conditions on samples is possible The stress application conditions and measurement data can be confirmed in real-time.

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.

This time, we will explain the differences in roles between the "accounting system" and the "document management system," which are surprisingly not well known, as well as points that are often overlooked in legal compliance. ■ The difference between accounting systems and document management systems is their "scope of coverage." - Accounting System = Management of "money (numbers)" - Document Management System = Management of "evidence (documents)" ■ Documents that are often overlooked in accounting systems The accounting system primarily focuses on "accounting processes." - "Estimates" where no money movement occurs - "Delivery notes" and "purchase orders," which are intermediate points in transactions ⇒ There are cases where these are not saved or managed in the accounting system. This could be considered a deficiency under the Electronic Bookkeeping Act. ■ Supplementing the missing parts with an "independent system" While there are high-function ERP (Enterprise Resource Planning) systems that can manage everything from estimates to invoicing seamlessly, the reality is that the cost can be a significant barrier to implementation. Therefore, there is also the option of managing documents with an independent document management system like paperlogic. Paperlogic is currently offering a free trial. Please feel free to contact us.
