"Quality Innovation" policy ensures customer-oriented quality assurance
Quality is the life of the product! For automotive electronics applications that are closely related to consumer safety, product quality is even more critical. The "Quality Innovation" policy put forward by Murata Manufacturing Co., Ltd. effectively strengthens the quality assurance system and meets the strict requirements of automobile manufacturers and vehicle equipment manufacturers on the quality and reliability of electronic components. In addition, Murata has set up a dedicated department responsible for the reliability evaluation of in-vehicle electronic components to better serve the automotive electronics field.
In order to provide customers with reliable and satisfactory high-quality products, Murata has formulated a "basic policy of quality management" that implements unified management in all aspects of design, material selection, procurement, production, sales and after-sales service.
"Basic Policy of Quality Management" refers to the continuous development of original products and new fields, based on the basic idea of ​​"high-quality machine systems come with high-quality parts and high-quality design, and high-quality parts come from high-quality materials and high-quality technology". , In all aspects of material selection, procurement, production, sales and after-sales service, all personnel of Murata Group coordinated and implemented the Deming Cycle. Through unified quality management, products that meet market quality requirements will be produced reasonably on the premise of ensuring environmental protection. And provide it to society.
In order to continuously improve the effectiveness and efficiency of the quality management system, Murata continuously improves the quality of products and services based on customers in the process of product realization from "planning design" to "production", "sales", "investigation and after-sales service" . Always reflect customer requirements in product improvement and provide quality that satisfies customers.

As a global business enterprise, maintaining high-quality products at a uniform level in the world is an important issue. Including overseas factories, all Murata factories have obtained the international standard ISO9001 quality management system certification. Especially in the automotive field, 11 manufacturers that produce automotive-related components have also obtained ISO9001 certification for the quality management standard ISO / TS16949, which has strict requirements for the automotive industry.
In the autumn of 2007, Murata Murata, the president of Murata Manufacturing Co., Ltd., proposed the "Quality Innovation" policy. Various activities aimed at quality innovation were carried out from top to bottom. The goal of this activity is to "customer-oriented" Quality assurance of this book ".
Unlike the previous production of general-purpose components, which are developed according to Murata's quality standards or products developed according to the performance indicators provided by customers, the goal of the new policy is to advance the necessary quality on the basis of understanding customer requirements and insight into technological development trends. And reliable products. This is what Murata calls a “quality assurance activity that moves customersâ€.
In a car, a small component defect often leads to a major accident. Therefore, electronic products for automotive applications must have a higher quality assurance system, such as more than ten years of durability guarantee, zero defects, and all-weather technical support system.
In response to these needs, Murata has carried out quality innovation activities on three axes: "strengthening the longevity", "improving quality by aiming at zero defects", and "strengthening the response to complaints." In addition, it also plans to actively invest in equipment aimed at strengthening the reliability test and failure analysis system.
The "Automobile Reliability Technology Section", a special-purpose department in charge of automotive technology in the quality assurance department of the head office, has become a key link in Murata's quality assurance system. The “Automobile Reliability Technology Section†was established in 2004, and its main role is to establish a reliability guarantee mechanism based on the premise of the harsh environment unique to the car. Specifically, it refers to grasping the model and mechanism of wear and aging of vehicle-mounted products, its mechanism, and limit life. Master the harsh environment unique to automobiles and formulate corresponding test standards. Realize the design that considers the endurance life, and its test procedures, etc. These are all conducted under the leadership of the Automotive Reliability Technology Section.
There are three kinds of failure factors for components: "internal factors" inside the components, "external factors" due to the stresses imposed by the factory's manufacturing process and the stresses imposed by the use environment after being placed on the market, and "temporal aging factors". These three are intertwined, resulting in malfunctions after the components are placed on the market. From the perspective of component manufacturers, although the internal cause and the mechanism of temporal aging can be grasped, it is difficult to obtain information on the external factors imposed after the product is shipped and delivered to the user. Therefore, Murata has launched its own collection of information and data on external causes in order to accurately grasp the customer requirements and use environment information related to reliability issues, and provide customers with products that meet the requirements in a timely manner.
The production of new functional products requires the development of corresponding components. Murata carries out "design sharing" activities from the development and design of new products to the cooperation between the technicians of both parties with the electronics manufacturers of major customers.
Through this activity, Murata participates in and communicates with customers in the early stages of the development of new functional products to provide customers with the best electronic components they are satisfied with. Since 2005, Murata has visited major car body manufacturers in Japan, Europe, North America and China, as well as automotive electronic equipment manufacturers called "TIer1", and exchanged opinions on reliability and quality. As many as 34 companies visited. Based on the information obtained from these activities, Murata began to improve the specific strategies and objectives related to reliability, as well as the company's internal reliability evaluation standards.

Murata Manufacturing Co., Ltd. took the lead in conducting a survey on the use environment of vehicle-mounted equipment. Such as the investigation of the environment inside the tire. The role of the tire pressure monitoring system (TPMS) is to automatically monitor the tire pressure in real time during the driving process of the car, and to alarm the tire leakage and low air pressure to ensure driving safety. The pressure sensor and conversion circuit are embedded in the TPMS, but there is almost no information about the internal environment of the tire. Murata conducted a variety of driving tests with real vehicles and investigated the environment inside the tires. Through the results of the emergency brake test, highway test, bad road test and corner test, we found that the environment inside the tire is actually very bad. By applying these valuable new information to the design, Murata can propose product solutions with the quality and reliability that customers value.
The Fiber Optic Splice Closure is suitable for protecting fiber cable splices in straight-through and branching applications. The F.O.S.C. can be placed in aerial, underground direct buried, wall-mounted, manhole and duct applications.
Based on an advanced formula, the plastic parts are made of injection-molded, high-strength engineering plastic PC by numerical control equipment, therefore effectively prevent products from aging caused by coldness, heat, oxygen and ultraviolet radiation
