FPC柔性电路

概述:

       当今产品发展日趋轻、薄、短、小,有些产品PCB并不能很好地满足要求,柔性电路FPC的应用更加契合多数客户的设计要求。捷卡长期服务于知名企业,在FPC的设计、质量、成本的管控已积累一定经验。我们将FPC同面标结合衍生出薄膜开关产品,优化人机交互界面,简化安装,提升其空间利用率。

  相比硬质印刷电路PCB,柔性电路FPC以其体积和重量优势,在三维空间内任意移动和伸缩,大大增加了其在电子设备上的应用性和灵活性。并且FPC还具有良好的散热性和可焊性,易于组装,精密程度高,稳定性良好。而对于承载要求较高的电路应用,软硬结合的方案亦可完美解决两个方案各自的痛点。

FPC种类:

1、  单面板-- 采用单面PI敷铜板材料于线路完成之后,再覆盖一层保护膜,形成一种只有单层导体的软性电路板。

2、  双面板--使用双面PI板敷铜板材料于双面电路完成后,两面分别加上一层保护膜,成为一种具有双层导体的电路板。

3、多层柔性版-- 多层柔性板是将三层或更多层的单面柔性电路板或双面柔性电路板层压在一起,通过钻孔、电镀形成金属化孔,在不同层间形成了导电的通路。

4、  软硬结合板-- 由刚性和柔性基板有选择地层压在一起组成。结构紧密,以金属化孔形成导电连接。

Membrane switches, which are also referred to as Membrane Keyboards or Membrane keypads, are made by printing colored and conductive inks onto Polyester or Polycarbonate films. The top layer creates the graphical design whilst the lower layers contain the printed circuitry layers.

A membrane switch operates when electrical contact is made by pressing the finger onto the switch contact area and broken when the finger is released. With the addition of metal domes within the structure, it is possible to add a specific tactile response for each key.

It is an electrical control for turning a circuit on and off.  Membrane switches are more cost-effective and take up less design space than mechanical switches or buttons because of their low profile. Membrane switches are easy to clean which makes them ideal for Medical or industrial controls.
