On May 26, 2015, TDK Corporation (President: Shang Kejian) announced that it will add high temperature X8R resistance to the resin electrode series with high reliability for substrate warpage and thermal cycling (150 °C temperature guarantee) ) series products, and will start mass production from June 2015.
In recent years, the number of electronic components has been rapidly increasing in the context of the development of automobiles and electronics. At the same time, it has become a trend to install electronic control units in the vicinity of components such as the engine compartment for the purpose of securing the interior space, reducing the wiring harness, and improving fuel efficiency. This requires that the electronic components mounted in such locations must have strong heat resistance and shock resistance.
TDK's resin electrode products have three characteristics and are well received by customers. These three characteristics are: welding crack countermeasures caused by thermal cycling, component damage countermeasures caused by vibration and impact, and deformation caused by the substrate. Warping crack countermeasures. The newly added X8R resin electrode series faithfully extends the advantages of resin electrode products to the industry's top X8R feature lineup. In addition, the product supports the industry's only *1005 shape, and it is expected that the opportunities for use in products such as ECUs that are becoming smaller and higher in density will continue to increase.
the term
· X8R characteristics: The operating temperature range is -55 ° C to 150 ° C, and the electrostatic capacity change rate is ± 15%.
· Warpage crack: refers to the deformation of the substrate caused by the insertion of the printed circuit board, the socket, the fastening screw, the insertion component, etc. after the laminated ceramic capacitor is soldered to the substrate. A problem of cracks on the basic components of the layered ceramic capacitor.
· Welding crack: refers to a phenomenon in which the stress at the welded joint increases due to the difference in thermal expansion coefficient between the electronic component and the substrate in a temperature environment where the temperature is repeatedly changed between high and low temperatures, resulting in cracks in the welded portion.
main application
