  The data used by the electrical connector will have a great impact on its function and quality. Therefore, if you want to improve its technical function and quality, you must effectively control the quality of the original data from the source, and from what aspects can you stop the quality of the data used What about temperance?

  First of all, to ensure the reliability of the electrical connector, the planning staff must stop the fair selection of materials based on the application request. The specification and form of the selected data trademark shall meet the application request. At present, there are many materials on the market that meet the purchase request regardless of the trademark, specifications or the old form. However, the actual appearance and connotation quality of the materials of different manufacturers are very different. Some materials are far from being able to meet the special circumstances of aerospace electrical connectors. Therefore, in the selection of materials The quality status and data specifications of the manufacturer should be compared from time to time, and if necessary, a technical agreement should be signed with the manufacturer to ensure that the selected data meets the requirements of the aerospace situation.

  In the process of selling original materials, it is often impossible to purchase goods from normal channels due to a small order quantity, and can only be processed through market promotion or instigation. There are many problems with the quality of these materials, for example: lack of original materials and passing verification documents, and even some passing certificates. No batch number, no specification, and no measured data. These data are not only easy to take effect, but also bring various hidden dangers to the current aerospace use. Therefore, the original data supplier must be audited and investigated at various levels before selling, and only after passing the audit and research can they enter the qualified supply list and stop selling.

  Because the original materials have a great influence on the quality and reliability of electrical connectors, even if the materials supplied by the supplier are qualified, the product quality, trademarks, specifications, etc. meet the requirements, and the original materials for promotion must be tested before they are put into the warehouse. The instrument stops retesting it. However, at present, the only way for many manufacturers to check the original data into the warehouse is to stop random inspections on the surface and size of the original data, and there is no useful inspection equipment. When re-inspection of the original data is stopped, the original data owner's factory re-inspection item list should be established, and the physical and chemical functions of the data should be re-inspected, requesting that the trademark, specification, form and appearance quality of the data used in the parts meet the requirements of the specification. Some materials that are in small quantities and cannot be supplied by the manufacturer are required to be re-inspected. As long as the re-inspection results are satisfactory, they can be used in the warehouse.

  In order to ensure that the re-inspected original materials do not show mixed materials or mixed batches, it is necessary to handle the batches of the original materials. The important thing to stop batch processing is to mark the date of entry of the original materials and record the re-inspection data. Some non-metallic materials have The use of the deadline also needs to mark the production date and the storage stop date. Once the expiration date is exceeded, the re-inspection procedure should be stopped, and it can be used continuously only after the re-inspection is passed. Batch processing effectively guarantees the accuracy and traceability of data release data and verification documents.
