柔性线路板的优势是什么?
灵活性
:柔性电路板的主要优点是其弹性和弯曲能力。因此,可以用各种方式操纵它们以适合边缘,折叠和折痕。电路板的灵活性还意味着它比普通的PCB更加可靠和耐用,因为它可以减少振动的影响,并且电路板上的配线很少。最少的布线消除了对接口连接的需求,例如焊点,触点压接和连接器。
减少重量和空间
:与其他解决方案相比,柔性印刷电路板不仅可以提供更大的设计自由度,而且还可以提供更好的空间利用率和重量效率。柔性印刷电路板又薄又轻,可以大大减少重量和空间。对于较小的设备,可以将这些柔性板折叠,折痕并放置在较小的区域中,以使设备小型化。这使得柔性电路板更适合小型设备,因为它们可以安装在刚性电路板无法安装的地方。
适用于恶劣环境
:柔性电路板可以使用各种耐腐蚀的材料制成,可以承受恶劣的环境。这些材料可以是防水,防震,防潮甚至是耐腐蚀的。因此,这些挠性板由于其坚韧和耐久的品质而广泛用于军事和医疗应用。板的自然柔韧性还可以更好地吸收冲击和冲击。
更好的热管理
:柔性电路板由聚酰亚胺制成,具有出色的热稳定性,可承受极高的热量。这也意味着改进的散热性能使该板成为表面安装的更好基础,并且不太可能发生热膨胀和收缩。柔性板还可以比其他解决方案更快地散热,从而提高了其热效率。
降低成本
:柔性电路板可以通过多种方式帮助降低组装成本。PCB的聚酰亚胺材料又薄又轻,这意味着它需要的空间较小。更少的空间需求意味着最终组装包装尺寸和材料成本的要求。由于柔性板消除了将导线布线到焊点和连接器的需要,因此,由于需要的组件数量减少,进一步降低了组装成本。通过减少板上的组件和导线的数量,可以减少测试和返工时间,从而提高生产率和效率。
“柔性电路板”有什么用?
1、柔性电路板使用在数码产品上较多。它和刚性电路板的区别在于电路板的基材不同,柔性顾名思义就是板材可以弯曲比较柔软。
2、“多层板”与“双面板”主要是指电路板上布线的面数,几面有线就是几层板。2层以上的都是多层板。从工艺流程看,多层板需要经过内层图转的加工,压合后才能进行外层的加工,外层的加工流程与双面板的加工流程基本一致。
FPC是什么意思?
FPC一般指柔性电路板。
柔性电路板(Flexible Printed Circuit 简称FPC)是以聚酰亚胺或聚酯薄膜为基材制成的一种具有高度可靠性,绝佳的可挠性印刷电路板。具有配线密度高、重量轻、厚度薄、弯折性好的特点。
柔性电路板产前处理:
在生产过程中,为了防止开短路过多而引起良率过低或减少钻孔、压延、切割等粗工艺问题而导致的FPC板报废、补料的问题,及评估如何选材方能达到客户使用的更佳效果的柔性线路板,产前预处理显得尤其重要。
产前预处理,需要处理的有三个方面,这三个方面都是由工程师完成。首先是FPC板工程评估,主要是评估客户的FPC板是否能生产,公司的生产能力是否能满足客户的制板要求以及单位成本。
如果工程评估通过,接下来则需要马上备料,满足各个生产环节的原材料供给,最后,工程师对:客户的CAD结构图、gerber线路资料等工程文件进行处理,以适合生产设备的生产环境与生产规格,然后将生产图纸及MI(工程流程卡)等资料下放给生产部及文控、采购等各个部门,进入常规生产流程。
