Introducing a test that allows for the observation of fracture and delamination layers by permeating coloring liquids and fluorescent liquids!

We would like to introduce our "Dye and Pry Test for Embedded Components." For confirming the breakage and delamination of packages and embedded components, there are non-destructive testing methods (such as transmission X-ray and CT) and cross-sectional observation. However, these methods make it difficult to capture the spread of delamination in the "plane" of the broken layers. In the Dye and Pry Test, by permeating a colored or fluorescent liquid, we can observe the broken and delaminated layers. Please feel free to contact us if you have any inquiries. 【Flow of the Dye and Pry Test】 ■ Dye immersion ■ Pry ■ Observation using optical microscopy or SEM *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.

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, not only does stress occur due to thermal effects, but also due to 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.

Introducing the "Observation Mode" of a chip capacitor (MLCC) under a microscope!

We would like to introduce an example of cross-sectional observation of mounted components conducted by our company. Using commercially available computer circuit boards, we observed the solder joints of mounted components and the internal structures of the components with a metallurgical microscope. The observation modes of the metallurgical microscope include bright field observation, dark field observation, and polarized light observation, among others. Additionally, there are observations using transmitted light, and the observation mode is selected according to the sample. By conducting cross-sectional observations before and after reliability testing, we can evaluate the reliability of the product. When observing, it is important to select an appropriate "observation mode" to clearly capture the condition of the solder joint interface and defects such as cracks. [Case Overview] ■ Using commercially available computer circuit boards ■ Observing the solder joints of mounted components and the internal structures of the components with a metallurgical microscope ・Observation modes: bright field observation, dark field observation, polarized light observation, etc. *For more details, please refer to the PDF document or feel free to contact us.

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 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.
