What are the purpose and application of rigid-flex PCB?

  • Rigid-flex PCB is a special flexible PCB composed of rigid PCB and flexible PCB laminated together, with a compact structure, and metalized holes to form electrical connections. It has the characteristics of high density, thin traces, small aperture, small size, light weight, and high reliability. It is still stable under vibration, impact, and humid environments.
  • Rigid-flex PCB has a bendable and three-dimensional installation, which effective use of installation space, is widely used in mobile phones, digital cameras, digital video cameras and other portable digital products.
  • Advantages of rigid-flex PCB,
    1. Save the process of using connectors or soldering Hot Bar.
    2. Shorten the signal transmission distance of the rigid-flex PCB and the speed is increased, which can effectively improve the reliability.
    3. Simplify product assembly and save assembly working hours.
  • Disadvantages of rigid-flex PCB,
    1. In terms of the unit price of “rigid-flex PCB” will be more expensive than “flexible board + rigid board”, but if adding the price of the connector or the cost of hot bar soldering, Prices may tend to be consistent.
    2. SMT and reflow oven may need carriers to hold the flex PCB, which increases the SMT assembly cost.
