- Types of PCBs
  • RIGID PCB (R.P.C)
  • FLEXIBLE PCB (F.P.C)

What is FPCB?

- FPCB, Flexible Printed Circuit Board
FPCB is a three-dimensional wiring circuit board designed in the form of a thin and bendable film that has excellent heat resistance, bending resistance, and chemical resistance, and is easy to assemble due to minimalchange in dimensions.

Need for FPCB

The use of FPCB blocks the possibility of breaking of existing PCB cables that can occur when moved several times due to poor flexibility, so it can be used in narrow and complicated spaces. In addition, unlike PCB, which requires shouldering by connecting wires and cables at multiple points, in turn reducing the work speed significantly, FPCB can act as a conductor with one or two shouldering.

Fields of Application

Introduction to the Process

  • Drilling
    A process of making holes for electrical connection between the inner and outer layers using a laser
  • Copper plating
    A process of metal electrodeposition on the holes drilled for electrical connection between layers after the drilling process
  • Pattern
    A formation of circuits for products through D/F coating - exposure - development - etching - desquamation
  • Solder Resist
    Protection of product circuit using cover lay and PSR ink
  • Surface Treatment
    Plating process for ease of SMT and anti-oxidation
  • Attaching Stiffener and Inspection
    Enhancement of durability and quality inspection using SUS, PI, FR4, and Stiffer
