Code name category ( Male/female) Material specification of electroplating electroplating thickness plating is environmental protection product specification SIM card phone terminal C5210 T = 0. 2 don't plating, cleaning grease 000 picth overrunning size tolerance and flatness is a vertical degrees straightness weight 5. 0400 + / - 0. 02 + / - 0. 02 + / - 0. 02 + / - 0. 02 + / - 0. 02 about 0. 5 grams of characteristics of the material fatigue resistance is very good, need to resist fatigue experiment more than 10000 times USES SIM card mobile phone terminal, high precision up to + / - 0. 01 mm precision, can satisfy the demands of different product assembly (1) the design of the SIM card mobile terminals must satisfy the product use and technical performance, and can be convenient for assembly and replacement. 2 design SIM card mobile terminals must be beneficial to improve the utilization rate of metal materials, reduce material varieties and specifications, as far as possible, reducing the consumption of materials. In the permission of using cheap materials, as far as possible make the parts do not waste and waste less cutting. (3) the design of the SIM card mobile terminals must be simple shape, reasonable structure, in order to help simplify the mould structure, simplify the process, which is the least, the most simple stamping process to complete the entire parts processing, reduce processing with other methods, and is advantageous to the stamping operations, is advantageous for the organization to realize mechanization and automation production, in order to improve labor productivity. (4) design of SIM card phone terminals, in can ensure normal use case, make dimensional precision lower level and the surface roughness level requirements, and promotes the exchange of products, reduce scrap, guarantee the stability of product quality. 5] design of the SIM card phone terminals, as far as possible should be conducive to use existing equipment, process equipment and technological process for machining, and is helpful to extend the service life of die.
