ATSC电视用的模拟-数字信号转换器在设计上要求必需通过美国相关质监部门认证,在设计上需要更加严谨地考虑其材质、结构及人性化等问题,这些都直接涉及到产品坚固性、环保要求。因此在设计时采用简单、成熟的“组合式”产品结构。产品由前面板组件(前面板、按键、导光柱、装饰片),上盖,下盖和PCB板组件等四部分组成,为电子部分提供支撑、定位、电磁保护、指示等功能,并起到美化产品的作用。
ATSC TV with analog - digital signal converter in the design requirements must pass the relevant quality supervision departments in the United States certification, the design needs to be more stringent to consider the material, structure and humanity and other issues, which are directly related to the product rugged, Environmental requirements. Therefore, the design of simple, sophisticated “modular ” product structure. Products from the front panel components (front panel, buttons, light guide columns, decorative films), cover, cover and PCB components such as four components for the electronic part to provide support, positioning, electromagnetic protection, instructions and other functions, and play Beautify the product’s role.
