About the curing temperature of epoxy resin free from hazardous substances.

We conducted measurements to reconfirm the temperature at which heat is generated during hardening!

We conducted measurements to reconfirm the temperature of heat generation during curing, following the change to a non-toxic epoxy resin. When using a large amount of resin, we apply heat prevention treatment for resin embedding. Without this treatment, the temperature can rise to 138°C during curing. However, with the heat prevention treatment applied, we were able to keep the heat generation during curing to within 30°C, even with a large amount of resin. 【Measurement Results】 ■ Without heat prevention treatment for a large amount of resin (large container) - Heat generation reached up to 138°C during curing. ■ With heat prevention treatment for a large amount of resin (large container) - Heat generation during curing was kept within 30°C. *For more details, please download the PDF or feel free to contact us.

Even with larger-sized implementation boards, resin embedding is possible without cutting before embedding! We will introduce cases with and without heat generation prevention treatment.

Epoxy resin is transparent, has a low shrinkage rate, and is often used for making cross-sections. However, since it is a thermosetting resin, it generates heat during the curing process. The temperature of heat generation varies depending on the amount used and the mixing ratio of the main agent and hardener. When embedding large samples such as printed circuit boards and touch panels, the epoxy resin can generate enough heat to deform the sample substrate. Therefore, we investigated how much heat is actually generated during curing. For more details, please refer to the PDF download below. 【Overview】 ■ Temperature profile acquisition - Without heat prevention treatment for a large amount of resin (large container) ■ Temperature profile acquisition - With heat prevention treatment for a large amount of resin (large container) ■ Resin embedding is possible even for larger printed circuit boards without cutting before embedding. *For more details, please refer to the PDF document or feel free to contact us.

Calculating the crack rate of ball joints and implementing it according to customer specifications!

After the solder durability test on the circuit board, if cracks occur in the solder joints, the crack rate will be calculated to confirm whether the cracks are within the allowable standards. The evaluation standards after the solder durability test can be individually defined based on the product environmental specifications, so most customers have their own standards. The measurement methods vary according to the shape of the components, but when you make a request, we will carry out the tests according to your specifications. 【Service Contents】 ■ Solder joints of BGA - Calculation of crack rate for ball joints ■ Solder joints of chip resistors - Calculation of crack rate for both ends of square and rectangular terminals ■ Solder joints of coil components - Calculation of crack rate for ribbon leads and QFP leads *For more details, please refer to the PDF document or feel free to contact us.

Mechanical grinding allows for a wide range of processing and observation! We will propose appropriate processing and observation methods or combinations.

We will introduce sample processing using mechanical polishing and mechanical polishing combined with ion milling treatment. Mechanical polishing is a common and long-established method for creating cross-sections, allowing for a wide range of cross-sectional production. Additionally, by combining it with ion milling treatment, it is possible to create observation surfaces comparable to those produced by CP processing. At Aites, we propose appropriate processing and observation methods or combinations based on our accumulated know-how. Please feel free to contact us for consultations or inquiries. 【Features】 ■ Mechanical polishing allows for extensive processing and observation. ■ By repeating mechanical polishing and imaging, three-dimensional observation is possible. ■ Observation at any desired location can be performed based on the constructed 3D image. ■ After mechanical polishing, depending on the sample, observation comparable to that of CP processed samples is possible. *For more details, please refer to the PDF materials or feel free to contact us.
