_Full description of mobile phone development-classic document 1105011 receiver development process January 1, 2011 First, the motherboard solution is determined in the mobile phone design company, which is generally divided into the marketing department (hereinafter referred to as MKT), the appearance design department (hereinafter referred to as ID), and the layout design department (hereinafter referred to as MD). A mobile phone project starts with a motherboard specified by the customer. The customer chooses a suitable motherboard according to market demand, gets the 3D drawing of the motherboard from the solution company, and then finds the design company to design a certain style of appearance and layout. There are also customers who directly find the design company to design a completely new motherboard. This requires the mobile phone layout engineer to cooperate with the solution company to stack the new motherboard according to the customer\'s requirements, and then do the follow-up work. This is not introduced in detail. When the design company\'s MKT signs an agreement with the customer and gets the 3D drawing of the motherboard given by the customer, the project officially starts, and the MD\'s work begins. Second, the design guidance-guided construction. Get the 3D drawing of the motherboard. The ID cannot be called directly. MD is also required to convert the 3D drawing of the motherboard into six views and calculate the basic dimensions of the whole machine. This is the basic skill of MD. I used it as a test question for the company\'s recruitment. You will know whether you have independently made a mobile phone after taking the test. If you answer incorrectly, it will be useless even if your resume says you have rich experience. In fact, the answer is very simple. Take a mobile phone with a touch screen as an example. For example, the length of the motherboard is 99, and the length of the whole machine is to add 2.5 at both ends of the motherboard. The length of the whole machine can be 99+2.5+2.5=104. For example, the width of the motherboard is 37.6, and the width of the whole machine is to add 2.5 on both sides of the motherboard. The width of the whole machine can be 37.6+2.5+2.5=42.6. For example, the thickness of the motherboard is 13.3, and the thickness of the whole machine is to add 1.2 on the top of the motherboard (including 0.9 upper shell thickness and 0.3 foam thickness), and add 1.1 on the bottom of the motherboard (including 1.0 The thickness of the battery cover and the battery assembly gap of 0.1), the thickness of the whole machine can be 13.3+1.2+1.1=15.6. There is no unique answer. As long as you can explain the calculation method, you should also point out the issues that need to be paid attention to when designing the appearance of the ID. This is a complete design guide. 3. Determination of the appearance of the mobile phone ID Get the design guide, first learn to draw...
