Demystify flexible pcb design specifications!

Flexible PCB is an innovation on traditional PCB, referred to as FPC. There are two basic materials for flexible PCBs, namely polyimide or polyester film. Compared with traditional circuit boards, flexible PCBs have excellent flexibility and high reliability. And what about such high-performance flexible PCB design specifications? This article will reveal the secret simply for you!

There are many advantages of flexible PCBs, and the professional knowledge required for design specifications is naturally more. If the detailed description is too tedious, then let's take a look at the more important process.



Demystify flexible pcb design specifications!

      1. FPC design preparation
      2. FPC wiring
      3. FPC via processing
      4. Trace spacing control
      5. Silkscreen requirements
      6. Teardrop treatment
      Teardrops should be added to all the connections between the PAD and the circuit, and the bends of the circuit need to be rounded to avoid breakage during bending or welding.
      7. Production of gerber files (gerber files and drilling files)
      8. Critical signal processing
      9. Copper processing
      10. Serpentine winding
      11. Other finishing commissioning work

Finally, let’s take a little knowledge of popular science. Flexible PCB was a technology invented by American scientists in the middle of the last century in order to comply with the development of space rocket technology. The purpose is to stack more precise components with more functions into the rocket. In a small and limited space. After historical changes and technological development, this technology has also been reduced from the original complicated design process to the twelve steps seen now. Even so, these twelve steps cannot be underestimated, because every step after this reduction requires Only by walking tightly and carefully can we provide more high-quality flexible circuit boards!
