  What do you need to consider when designing and distinguishing rigid PCBs and flexible PCBs?

  PCB widely used in all walks of life. From communications equipment to medical equipment, from small mobile phone to fly in the space of the Temple of God Shenzhou have PCB figure, its own types are also varied.

  Rigid circuit board

  PCB (Printed Circuit Board), the Chinese name for the printed circuit board, also known as printed circuit board, is an important electronic components, is the support of electronic components, electronic components is the carrier of electrical connections. Because it is made using electronic printing, it is called "printed" circuit board.

  Flexible circuit boards

  FPC, also known as "soft board" (Flexible Printed Circuit Board), is made of flexible insulating substrate printed circuit. Flexible circuits provide excellent electrical performance to meet the design needs of smaller and higher density installations, as well as help reduce assembly processes and enhance reliability.

  Flexible circuit boards are the only solution to meet the miniaturization and movement requirements of electronic products. Can be free to bend, winding, folding, can withstand millions of times the dynamic bending without damage to the wire, according to the space layout requirements of any arrangement, and in any three-dimensional space to move and stretch, so as to achieve the integration of components and wire connections Flexible; circuit board can greatly reduce the size and weight of electronic products for electronic products to high density, miniaturization, high reliability direction of the development needs.

  Because the use of different, so rigid and flexible PCB in the design of the time, is not the same, then, in the design of the time, need to consider what factors?


  The use of thinner laminates and wide wires can better improve the likelihood of its more cyclic bending. For a large number of bending cycles, single-sided flexible PCBs usually show better performance.


  In the vicinity of the pad, there is a change from the flexible material to the rigid material, which is easy to break the conductor. Therefore, the pad should be avoided in areas prone to bending.
