The data used in the electrical connector will have a great influence on its function and quality. Therefore, to improve its technical function and quality, it is necessary to control the quality of the original data from the source. In what ways can we stop the quality control of the data used?
First of all, to ensure the reliability of electrical connectors, the planning staff must stop the fair selection of materials according to the application request. The specifications and forms of the selected materials and trademarks shall meet the application requirements. At present, there are a lot of materials in the market, no matter the trademark, specification or form, all meet the purchase request. However, the practical appearance and connotation quality of materials of different manufacturers are quite different. Some materials are far from enough to meet the special situation of aerospace electrical connectors. Therefore, when selecting materials, we should stop comparing the manufacturer's quality conditions and data specifications, and sign technology with the manufacturer if necessary Be able to negotiate with each other to ensure that the selected materials meet the requirements of aerospace application.
In the course of marketing raw materials, due to the small amount of orders, it is often impossible to purchase from normal channels, but only through marketing or instigation, and there are many problems in the quality of these materials, such as: short raw materials and pass certification documents, so that some pass certificates have no lot number, no specification and no measured data. These materials are not only easy to take effect, but also the current aviation angel It brings all kinds of hidden dangers. Therefore, before the sales promotion, the original data suppliers should go through various levels of audit and research, and only after passing the audit and research can they enter the list of qualified suppliers to stop the sales promotion.
Because the original data has a great influence on the quality and reliability of the electrical connector, even if the data provided by the supplier is qualified, the product quality, trademark, specification, etc. are in line with the request, and the original data for sales promotion must be retested with testing instrument before warehousing. However, at present, the only inspection method for the original data storage of many manufacturers is to stop random inspection for its surface and size deviation, without any useful inspection equipment. When the reinspection of the original data is stopped, the factory reinspection item list of the original data owner shall be established, the physical and chemical function reinspection of the data shall be stopped, and the trademark, specification, shape and appearance quality of the data used for the parts shall meet the specification requirements. Some materials which are small in quantity and can not be supplied by the manufacturer are required to pass the reinspection, and can only be put into use if the reinspection effect is qualified.
In order to ensure that the raw materials for reinspection and warehousing do not present mixed materials and batches, it is necessary to handle the production batches of the raw materials. To stop batch processing, it is important to mark the warehousing date of the raw materials and record the reinspection data. If some non-metallic materials have a time limit for use, it is also necessary to mark the production date and the storage stop date. Once the time limit is exceeded, it is necessary to stop the reinspection procedures, as long as the reinspection passes, it can be continued application. Batch processing is useful to ensure the accuracy and traceability of data distribution and supporting documents.
If the original data presents quality problems in the course of re inspection and application, the analysis shall be stopped in real time. If the analysis effect is material accountability, the information shall be reflected to the manufacturer in real time, and the status of disposal and improvement shall be tracked in real time. At the same time, the inventory and the same batch of data on the production line shall be stopped.
As long as the quality of raw materials is basically controlled through the above steps, it can be useful to ensure the quality reliability and technical functions of electrical connectors.
