Observation of time-dependent changes associated with reliability testing.
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.

Observation of substrate deformation using a 3D shape measuring device (VR-6200)
I would like to introduce "Observation of Substrate Deformation Using a 3D Shape Measuring Machine." By applying pressure to the PCB substrate, referencing bending tests of plastics and PCB substrates, the change in state is measured using a 3D shape measuring machine (VR-6200). Since the measurement results can be confirmed with a color palette and line profile, it is possible to visually verify the shape and amount of deformation caused by the applied pressure.

Strain measurement of power module package resin.
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 the mounted state on a circuit board and in the unmounted state. In the mounted module, a slight delay in temperature change was observed, and correspondingly, the change in strain also appeared to be delayed. This is believed to be due to the slower transfer of heat to the module when it is mounted. At Aites, we conduct temperature cycle tests and temperature-humidity cycle tests, during which we can simultaneously measure the strain occurring in the mounted components. Please feel free to consult with us.

Measurement of moisture absorption distortion
We would like to introduce the results of our investigation into the behavior of strain during moisture absorption and drying using a strain gauge. It was observed that the material expands when it absorbs moisture due to humidification, contracts when it dries due to dehumidification, and the strain returns to the state before humidification. Regarding FR-1, it is presumed that the chemical structure of the material changed due to hydrolysis, which is why it did not return to its original state.

Strain measurement in thermal shock testing.
We would like to introduce the "strain measurement in thermal shock testing" conducted by our company. A sample with strain gauges attached was set up in the thermal shock testing device, and the wiring of the strain gauges 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 changes in temperature. It was found that FR-1 exhibited greater strain compared to FR-4.
