柔性印刷电路板（Flexible Printed Circuit Board）:简称FPC,它是一种新兴的高科技产品,以其固有的优特点,在越来越多的电子产品中,取代了以前的传统产品--刚性印刷电路板,具有广阔的市场前景柔性印刷电路板（Flexible Printed Circuit Board）是用柔性的绝缘基材制成的印刷电路，具有许多硬性印刷电路板不具备的优点：
　　（1）可以自由弯曲、卷绕、折叠，可依照空间布局要求任意安排，并在三维空间任意移动和伸缩，从而达到元器件装配和导线连接的一体化；
　　（2）利用FPC可大大缩小电子产品的体积和重量，适用电子产品向高密度、小型化、高可靠方向发展的需要。因此，FPC在航天、军事、移动通讯、手提电脑、计算机外设、PDA、数字相机等领域或产品上得到了广泛的应用；
　　（3）FPC还具有良好的散热性和可焊性以及易于装连、综合成本较低等优点，软硬结合的设计也在一定程度上弥补了柔性基材在元件承载能力上的略微不足。 

       Flexible printed circuit board: referred to FPC, it is a new hightech products, with its
inherentadvantages and features, in more and more electronic products, replaced the previous orthodoxy products  Rigid Printed Circuit boards, and has broad market prospect of flexible
printed circuit board is made of flexible insulation base material printed circuit, with many
rigid printed circuit  board does not have the advantages of ︰
    (1) Free bending, winding, folding, can be arranged in accordance with requirements of any
 space layout, and any move in three dimensions and scale to achieve the wires connected component assembly and integration;
    (2) The use of FPC can be greatly reduced size and weight of electronic products for elec-
tronic products to highdensity, small size, high reliability and direction of development. Th-
erefore, FPC in space flight, military, mobile communications, portable computers, computer
peripherals, PDA, digital camera and other fields or products have been widely used;
    (3) FPC also has good heat resistance and solderbility, and easy to install with integrted
and low cost,  integrated hardware and software design has to a certain extent make up for the flexible substrate on the carrying capacity of the component slightly inadequate.
