How do you make a cell phone?

Cell phones have a wide variety of uses, from making calls and sending text messages to browsing the Internet and taking photos. In addition, cell phones are used to work, study, make online purchases, play video games and listen to music. Mobile phones are one of the most popular and used technological devices around the world. Since their invention, cell phones have evolved significantly with new features and designs. But have you ever wondered how cell phones are made? In this article, we will explain the step-by-step production process of cell phones. Materials necessary for its manufacture The manufacture of cell phones requires a large amount of materials. The most important components are the processor, RAM, screen, battery and case. In addition, other materials such as copper, aluminum, plastic, glass, gold and silver are needed.fa Industrial processes necessary for its manufacturing The cell phone production process is very complex and requires the intervention of several industries. Below are the processes necessary to manufacture a cell phone: 1. Design: The first step is the design of the cell phone, which includes the selection of materials and the definition of technical specifications. 2. Manufacturing of components: The components of the cell phone are manufactured separately in different factories. For example, the processor is manufactured in a semiconductor factory, the display in an LCD panel factory, and the battery in a battery factory. 3. Assembly: Once the components are ready, they are sent to the assembly factory where they are joined together to form the cell phone. This process includes soldering the components to the motherboard, installing the battery, and placing the case. 4. Testing: After assembly, each cell phone is subjected to rigorous quality tests to ensure that it works correctly. 5. Packaging: Finally, the cell phones are packaged and sent to the distributors. Main global cell phone manufacturers and where they have their factories The main cell phone manufacturers globally are Samsung, Apple, Huawei, Xiaomi and Oppo. These companies have factories around the world, including China, South Korea, the United States and Mexico. Samsung is the largest cell phone manufacturer in the world and has factories in South Korea, Vietnam, India, Brazil and China. Apple, for its part, manufactures the iPhone in China and the United States. Huawei has factories in China and Europe, while Xiaomi and Oppo have most of their factories in China. All consumer technology manufacturers are very wary of showing off their machinery. Perhaps because what for some would be showing their power, for them means exposing themselves to imitations. However, we investigate and can make known the production process of mobile phones, from the first filament to the final packaging. Accessing different factories where millions of smartphones are generated per month is not easy. Before going to the production room you must remove all metal, belts, jackets... even earrings and shoes. Wearing a white coat, rubber flip-flops and a hat that collects hair, everyone who enters the factory must pass through airport-style security arches. Once inside, the plant is divided into production lines in which units of the firm's smartphone are manufactured non-stop. “One every XX seconds”, as highlighted by the different guides of the different factories that opened their doors to us. It all begins in the area called 'SMT', the first phase of order preparation. It is an area where dozens of rolls similar to cinema films are accumulated, but instead of scenes they contain metal filaments that are the raw material for what will later become a high-performance smartphone. The motherboard is prepared in this first phase. All the following components are included with different machines prepared for each of them on the motherboard. A scan is made of each component and if there has been an error, engineers are called to solve the problem. The different robots place the insulator, the glue that ensures that if the phone falls to the ground it is protected, the element that balances the internal and external temperature, etc. Until now the mobile phone has not been touched by anyone. It is from this step that the technicians appear on the scene. A row of workers assembles the parts of several devices at the same time. They place the camera lenses and other external components such as the screen, the touch panel and the fingerprint recognition sensor. Once finished, we move on to 'testing' where the terminal is tested under “extreme” conditions to determine how it works.
