The customized development board process usually includes the following key steps:
1、 Requirement analysis
Requirement analysis is a crucial step in hardware development customization. The speed of hardware iteration is relatively slow compared to software iteration, but hardware iteration may lead to changes in the overall structure. Therefore, the accuracy of demand analysis will directly affect the quality, cost, and development time of the product. At this stage, it is necessary to clarify the functional requirements, performance requirements, and usage environment of the development board to provide guidance for subsequent design work.
2、 Overall scheme design and review
Based on the requirements analysis, design the overall plan. This includes determining the overall architecture of the development board, selecting processor models, interface design, power management, etc. After completing the scheme design, it is necessary to conduct a review to ensure the rationality and feasibility of the scheme. After the review is approved, further hardware design work can be carried out.
3、 Hardware design and review
Hardware design mainly includes the design of schematics and PCB diagrams. Schematic design is the primary step in hardware design, which requires consideration of various issues such as wiring, electromagnetic, heat dissipation, anti-static, power consumption, and signals. In the design process, it is necessary to ensure correct connections between various circuit modules and stable and reliable signal transmission. After completing the schematic design, proceed with the PCB design, including layout, wiring, etc. After the design is completed, review the schematic and PCB drawings with the client, promptly identify issues, and make modifications.
4、 Sample production
After the review is approved, the PCB circuit board will be sampled and produced. This step usually includes the production of PCB boards, procurement of surface mount components, and surface mount processing. When choosing a PCB manufacturer, factors such as production capacity, delivery time, and price need to be considered. At the same time, it is necessary to ensure that the quality and performance of the surface mount components meet the design requirements. After completing the sample production, conduct preliminary testing to ensure the reliability of the PCB board and surface mount components.
5、 Debugging and testing
Debugging and testing of PCBA boards, mainly focusing on debugging various functional modules, serial signals, power supplies, CPUs, etc. After debugging, conduct EMC (electromagnetic compatibility), functional, environmental, and reliability tests. This step is a crucial step in ensuring the quality of the development board and needs to be taken seriously. During the testing process, it is necessary to promptly identify problems and propose solutions for correction.
6、 Data archiving and acceptance
After passing the test, archive and save the files. This includes schematics, PCB diagrams, test reports, etc. The archived materials can provide reference for subsequent production and maintenance. At the same time, conduct acceptance work to ensure that the development board meets design requirements and meets customer needs.
7、 Batch production and subsequent maintenance
After completion of acceptance, mass production will be carried out. In the mass production process, it is necessary to strictly control the production quality to ensure that every development board meets the design requirements. At the same time, provide follow-up technical support and maintenance services to solve problems encountered by customers during use.
In summary, the process of customizing development boards is a complex and meticulous process that requires comprehensive consideration of multiple factors and careful attention to each step. Through scientific process management and quality control measures, the quality and performance of the development board can be ensured to meet design requirements and meet customer needs.
