Latest Patents
Yonezawa's latest patents include a method of manufacturing thermistors. This invention outlines a comprehensive process that involves several steps. The process begins with a base electrode layer forming step, where a base electrode layer is created on both surfaces of a thermistor wafer made from thermistor material. Following this, a chip forming step is conducted to cut the thermistor wafer into chips, resulting in thermistor chips with a base electrode layer. A protective film forming step is then implemented, where an oxide-based protective film is applied to the entire surface of the thermistor chip. The next step involves forming a cover electrode layer by applying and sintering a conductive paste on the end surface of the thermistor chip. Finally, a conduction heat treatment step is performed to ensure that the base electrode layer and the cover electrode layer are electrically conductive, completing the electrode portion. Another notable patent is for a thermistor that includes a thermistor element, a protective film, and an electrode portion. The protective film is made of a SiO film with a thickness ranging from 50 nm to 1000 nm, ensuring effective protection and functionality.
