Board),中文名称为印制线路板,又称印刷线路板,是电子元器件的支撑体、电子元器件电气连接的载体,是电子工业的重要部件,为5G通信发展提供基础保障。电子设备采用PCB后,由于同类PCB的一致性,可避免人工接线的差错,并可实现电子元器件自动插装或贴装、自动焊锡、自动检测,保证了电子设备的质量,提高了劳动生产率、降低了成本,并便于维修 /span span style=" font-family:

据了解,全球仅5G带来的射频侧基站用PCB年产值可达240亿元人民币/年以上(中国大陆预计占50%),是4G的四倍以上。5G的到来成为PCB行业未来3年的核心驱动力以及PCB行业增长的最大新引擎。 /span /p p style=" text-align: justify text-indent: 2em " span style=" background-color: rgb(183,

随着5G时代的到来,PCB企业为重塑核心竞争力,提出了“以质取胜”的发展口号。而可靠性试验是“以质取胜”基础实现途径之一,发挥着至关重要的作用,直接影响着中国5G通信技术的发展。 /span /p p style=" text-align: justify text-indent: 2em " span style=" font-family: & quot times new roman& quot " PCB在装机之前要经过一系列检查和测试,经过可靠性检测筛选的PCB可保证长期可靠地工作。若PCB安装之前未经过可靠性筛选,设备整机的故障率将大幅度提高,并要付出极大的代价去维修,造成企业高额的经济损失。 /span /p p style=" text-align: justify text-indent: 2em " span style=" background-color:

quot " 国内外大量统计资料表明,产品失效的基本原因,大部分是由环境因素引起的。由此可见,环境对产品有着较大的影响,环境试验对PCB品质保障也非常的必要。可靠性试验可通过人工模拟的方法实现环境参数对产品的试验考核,从而暴露和发现产品在设计、器件选用以及工艺等方面的缺陷和隐患,通过改进设计,以提高产品质量和环境适应性能力。 /span /p p style=" text-align: justify text-indent: 2em " span style=" font-family: & quot times new roman& quot " PCB在使用过程中因不同的使用环境,会受到不同环境的应力。为了确认产品能在这些环境下正常工作,国家标准、行业标准都要求产品在模拟环境下进行一些测试项目,这些测试项目包括:高温测试、低温测试、高低温交变测试、高温高湿测试、机械振动测试、运输测试、机械冲击测试、开关电测试、电源拉偏测试、冷启动测试、盐雾测试、雨淋测试、尘砂测试、雷击测试等。其中需用试验箱进行的测试项目有: /span /p p
