You can closely observe the soldering condition of electronic components on the implementation board and the internal structure of the components!

We conduct "cross-sectional observation of surface-mounted electronic components." Through cross-sectional observation after mechanical polishing, it is possible to closely examine the solder joint condition (presence of cracks or voids) of electronic components on the mounted substrate, as well as the internal structure of the components. For "SOP components," detailed observation can be made from the overall cross-section to the solder connection, and for "aluminum electrolytic capacitors," it is possible to observe the internal structure of the electrolytic capacitor components and their connection to the substrate. 【Features】 ■ SOP (Small Outline Package) components - Detailed observation can be made from the overall cross-section of SOP components to the solder connection. ■ Chip ceramic capacitors - Detailed observation can be made from cracks in the component material to cracks in the solder area. ■ Aluminum electrolytic capacitors - Observation can be made from the internal structure of the electrolytic capacitor components to their connection to the substrate. *For more details, please refer to the PDF document or feel free to contact us.

Introducing examples of aluminum welding observations. Internal observations through X-ray fluoroscopy and CT scans provide clearer insights after cross-section preparation!

Here is a case study of the observation of aluminum spot welds. Internal observation using X-ray radiography revealed voids within the weld, and internal observation using X-ray CT confirmed that the voids are located near the center of the weld (between the two aluminum plates). Additionally, by creating a cross-section of the same sample and combining mechanical polishing with chemical etching, we were able to observe the condition of the weld more clearly. 【Summary】 ■ Internal observation using X-ray radiography - Conducted non-destructive testing and X-ray radiographic observation - Voids were observed within the weld ■ Internal observation using X-ray CT - Conducted non-destructive testing and X-ray CT observation - Confirmed that the voids are located near the center of the weld ■ Cross-sectional observation using optical microscopy and tabletop SEM - Mechanical polishing and chemical etching A cross-section tailored to the sample allows for clearer observation. *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 acceptable standards. The evaluation criteria after the solder durability test can be individually established 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.

Three types of Pb-free soldered products are subjected to reliability tests! We will introduce the main objectives of each test and the results of cross-sectional observations.

We would like to introduce the cross-sectional observation of Pb-free solder after the reliability tests conducted by our company. Pb-free solder assemblies (Sn/Ag/Cu alloy solder) were subjected to three types of reliability tests. We compared the initial products with those after testing to check for the presence of cracks and the growth of intermetallic compound layers. To gradually confirm the durability of the solder joints, such as monitoring crack propagation, the TC test, which allows for cross-sectional observation after each cycle, is recommended. 【Test Conditions】 (1) TC Test (Temperature Cycle) 125℃ for 20 minutes / -40℃ for 20 minutes / 1000 cycles (2) HT Test (High-Temperature Storage) 150℃ for 1000 hours (3) TH Test (Temperature and Humidity) 85℃ / 85% RH for 1000 hours *For more details, please refer to the PDF document or feel free to contact us.

The seismic sensor device "HK-2" detects strong tremors equivalent to a seismic intensity of 5 or higher, transmits a signal to the control room, and emergency stops the facility equipment. 【Installation Location】 Automotive parts factory 【Challenges】 Due to the maintenance and replacement of the factory equipment control devices, we considered updating the existing seismic sensors as well, but since production had already ended, we were looking for alternatives. 【Effects After Installation】 The HK-2 has the function to emergency stop equipment during an earthquake, and since its functionality is the same as the existing device, it was introduced as a replacement. Its compact size also allowed it to fit within the existing control panel being used. ★See more examples of the seismic sensor device "HK-2" https://www.hotron.co.jp/recommend/HK-2_lp.html#anchor_a04 ◎For more details, please download the materials or contact us.
