The superior performance of the Apple mobile phone is very popular around the world, but the expensive Apple accessories make everyone very angry. Why are the prices of Apple iPhone accessories expensive?
Take last year’s new macbook charging cable, this cable uses a two-way Type-C interface. Type-C interface features are relatively comprehensive, Apple is promoting this interface, as can be seen from the Macbook, Apple will soon eliminate all USB-A interfaces. Why are the prices of Apple iPhone accessories expensive? First of all, I will introduce the Raw cable, which is environmentally friendly, free of halogen and easy to degrade. It has an impact on strength and is easy to break. But I heard that Cook himself has broken the data cable. Now the material is improved, it is very hard. There is bulletproof wire in the cable to enhance the tensile strength (not anti-broken wire, material kevlar, kevlar is the material of the bulletproof vest) cable inner core, the material will try a lot of materials in the research and development stage, and finally try the material is not convenient to disclose the proportion of specific components, Generally annealed copper + silver alloy.
Other plastic parts: All plastic parts of Apple are not allowed to be molded with secondary materials. All plastic parts must be made of environmentally friendly dsm materials.
Other metal parts: There is a ring inside the data cable, gold plated, copper etc. Later, silver was adopted. Other 304 materials are generally nickel plated.
Assembly size inspection: AOI automatic optical inspection, the assembly size accuracy is 0.01mm. This is very demanding on the accuracy of the parts and the fit between the parts and the assembly process.
Glue: Everyone knows that Apple likes to use glue. All glues in apple use advanced environmentally friendly glue. Yes, everyone can also know from Apple’s propaganda that Apple has been doing a good job in environmental protection.
In terms of technology, such as the current iPhone 8 fast lightning cable. There are 2 iron shells inside the connector plastic case to protect the pcb board. The iron shell is subjected to the main connector strength pressure. An experimental specification given by apple is 25kg pressure, and the factory specification is 1.5 times that of general apple. Our own request is to withstand 35kg pressure. We basically reached 35+ after laser welding.
iPhone 7 began to change the earphone box to paper packaging, and everyone may feel that it is cost-effective. But this is not the case, the paper packaging cost is very expensive and the assembly process requirements are very high, because it is too difficult to fold, no matter manual or equipment is difficult to complete.
