A kind of electronic product development that can see the real thing. For example, the mobile phone, mouse, keyboard, and audio are all hardware. Hardware development is also a series of studies conducted in these areas. Hardware development is generally divided into: schematic design, circuit diagram design, PCB board design, test board production, functional testing, stability testing, microcontroller design, small batch production, formal launch or formal use. 1. Identify the overall hardware requirements, such as CPU processing power, storage capacity and speed, I/O port allocation, interface requirements, level requirements, special circuit requirements, etc. 2. According to the needs analysis, develop the overall hardware plan, seek key devices and their technical materials, technical approaches, technical support, fully consider the technical possibilities, reliability and cost control, and put forward clear requirements for the development and debugging tools, the key The device asks for samples. 3. For detailed hardware design, including drawing hardware schematics, single-board functional block diagrams and coding, PCB layout, and completing development of bill of materials, production documents (Gerber), material claims. 4. After returning the PCB board and materials, arrange 2 to 4 boards for the board debugging, debug the functions in the principle design, and modify the schematic diagram and record if necessary. 5. The software and hardware systems are coordinated. The general board requires the cooperation of hardware personnel and board software personnel. After the board is debugged, some adjustments are made in the principle and PCB layout. 6. Internal acceptance and transfer to the pilot test, during the trial production, tracking the production line, actively assisting the production line to solve various problems, improve the excellent rate, and pave the way for mass production. 7. Small batch production. After the product has passed the acceptance test, it is necessary to carry out small-scale production, find out the production process, test the process, and prepare for mass production. 8. Mass production. After a small batch production verification of a complete set of electronic product development, testing, mass production process, there is no problem, you can start mass production work. The intelligent hardware development process can generally be divided into four phases, but you have to determine your basic delivery date, which is when the product will be available. Because each link can be fast or slow, naturally, the corresponding cost and quality will be slightly different. According to my experience after studying in Huaqing Vision, it takes six months to complete a product, less than four months, unless the things are very simple, or there are ready-made molds and solutions, and the materials are also very smooth, otherwise they will do Things that come out are generally not too good. Here are the four processes of the intelligent hardware development process I learned from Hua Qingyuan's teacher: 1) Demand discussion stage - it is recommended to schedule at least one month Main business: clarify the market demand for products, determine the final list of functions, etc.; 2) prototype stage - about 2-3 months Main business: hardware, software, structure, etc. development (and walking) is estimated to be more than 2 weeks, playing board, patch, etc. 7-10 days 3) Trial production period - 2 weeks to 4 weeks Under normal circumstances, a small batch (within 100pcs) can be trial-produced in 2 weeks. The main business: production process and process decomposition arrangement 4) Mass production stage - the first batch of goods around 2 weeks (about 1K) Under normal circumstances, it is necessary to wait for some certification to be completed, and then start a large-scale production after receiving a formal order. These are generally outsourced, and the landlord should not need too much attention. In Lingxin's intelligent toy system, the toy's question and the toy's response use the voice compression codec technology. The user answers the toy's question and uses the non-specific voice recognition technology. These three steps are treated as a script node in ITDAL, and a complete script includes multiple such script nodes. ITDAL re-scripts the toy prompts in the script node, the user's possible answer sets, and the responses to each answer, and compiles and simulates to generate the final mapping file for download to the toy. The system also realizes the download function from the PC in the hardware, which can realize the script update of the “database website†to the toy terminal, greatly improving the novelty of the toy, and adding the function of educational puzzle on the basis of entertainment. . For a well-designed script idea, record the pronunciation of the toy (prompt tone) according to its content, and prepare to identify the vocabulary. Then, the script is edited according to the ITDAL system on the PC, and the final mapping file is generated in combination with the prompt sound file. The prepared mapping file is downloaded to the toy terminal through the USB port, and the implementation of the script is completed. 1, do not ask for speed, hardware must be done in a down-to-earth manner. The normal speed is also a three-month period. Many people may ask why Huaqiangbei's cottage can be shipped in one month. This is because the premise of fast shipment of cottages is based on the assembly of standard parts, such as mass production. A PCBA can only be changed in appearance or packaging. It can be shipped quickly, but there are too many links in the newly designed products. The longest period of the abrasive tool usually takes 30 days. The PCB design and sample to production usually take more than a month. 2. It is especially important that the project does not change frequently during the course of the project. Hardware changes are very cumbersome. For example, if some functions are added, it is necessary to change the chip to re-route a circuit board. The appearance changes will affect the modification of the abrasive structure. It is very likely that the entire grinding tool is damaged and the product cycle is greatly delayed. . 3. Find a solution provider who has already done similar products to cooperate. In fact, if the hardware products are subdivided, there are a lot of them. Don't think that you will do Bluetooth when you have done wifi. If you do MTK, you will be a Qualcomm mobile phone. Any different technical solutions will take time to learn. Accumulation, if you are looking for a team that has never done a similar product, don't have too many expectations in terms of time and quality. 4. Don't pay too much attention to the scale of the solution company. Cooperating with this thing, cooperation is very important! If a small team with experience is willing to do 100% of the time to help you with a product, then this must be a priority. Many large solution companies will pick up a lot of products at the same time in development, and the cooperation is not very good. 5. Don't think that hardware costs are low and profits will be high. The hardware engineer with a little experience in Shenzhen has a monthly salary of more than 20k. The general design company should design a product and design the structure. It must also have a level of 40,000 to 80,000. A simple product mold must have at least 100,000 molds. Fees, so the hardware is also to fight sales, if there is not a few K sales guarantee every month, I advised to consider carefully. 6. Choose a reasonable price, which I think is the best choice. Of course, local tyrants can directly choose big factories, but start-up companies should not choose small factories with cheap prices, especially the abrasive tools factory. I have encountered many abrasive tools and want to throw away the impulse to change factories immediately, and the abrasives factory chooses direct It affects the appearance and overall quality of the product and is irreversible and unoptimizable. 7. If there are products with high quality requirements, there are several links that are most important. 1 industrial design level, 2 selection of abrasive tools manufacturers, 3 assembly factory quality control, these three links determine the quality before, during and after production. And in the assembled factory, it is best to send a factory to the factory, so that the last ring can guarantee the quality of the product. 8. Accept the opinions of senior people in the industry. Making products is an art of compromise. Don't stick to high-risk processes or unusually high production methods. The cost of control is not only in the chips and solutions you choose, but also in the process of mass production, how to control the non-performing rate and increase the production speed. . In addition, it is better for Internet companies to have a person who understands the hardware R&D and production process. Don't let a person who does not know how to follow up the hardware products. If the person who needs to actually execute does not understand the business, Then the problems encountered in the cooperation process are difficult to solve.
