Flexible PCB

Custom flexible pcb board from PCBSKY,  pcb manufacturer in china shenzhen, a TRUE PCB MANUFACTURER.
Because of the advantages (for example, cost, space, and weight savings) that flexible and Rigid-Flex-circuit boards have for some projects, they are used ever more frequently. PCBSKY can produce your flexible circuit boards with the highest quality, either as prototype or as series with 1-10 layers.

The standard surface used is chemical gold (ENIG), the contours are formed according to requirements, preferably using laser cutting, or also with mechanical milling.
You should discuss the selected materials and design for the construction and layout of flexible circuit boards with us in the planning phase; we can assist you to work out the optimum solution!
  • Single Sided Flexible PCB Single Sided Flexible PCB After the completion of the circuit, the single-sided PI-clad material is covered with a protective film to form a flexible fpc with only a single layer of conductor.Structure of single-layer fpc: The...
  • Double Sided Flexible PCB Double Sided Flexible PCB After the double-sided PI board copper-clad board material is used in the double-sided circuit, a protective film is added on both sides to form a circuit board having a double-layer conductor.The str...

Exploring the Many Advantages of Flex Circuit Boards

  • Reduced Space and Weight: Most of the advantages associated with flexible PCBs come from their low volume and weight. In fact, using a flexible PCB instead of a rigid PCB can result in a space reduction of over 50 percent and a weight reduction of 95 percent, while simultaneously maintaining the function and reliability of the circuit.
  • Durability: The flexibility, reduced weight and reduced number of interconnects in PCBs allow them to handle changing external forces and improve their resistance to shock and vibration.
  • Signal Integrity: Flexible PCBs work in a wide range of environments, so signals will continue to perform smoothly despite exterior conditions. This improves the PCB’s signal reliability.
  • Higher Density: The thin layers and smaller parts mean that flexible PCBs are capable of supporting higher circuit densities.
  • Minimized Errors: Due to the elimination of mechanical connectors and reduced variations in assembly methods, flexible PCBs experience reduced wiring errors.
  • Low Cost: Because of the fewer assembly steps involved in the creation of flexible PCBs, they tend to be relatively low-cost.
  • Heat Dissipation: The thinner material of flexible PCBs allows for a greater surface-area-to-volume ratio, improving heat dissipation.
