Yamashita Materials's Track Record

Serving the Medical, Optical Communication, and Automotive Industries

Yamashita supplies FPCs to a wide range of sectors. For the medical industry, they produce ultra-thin, lightweight, high-density FPCs used in devices such as imaging systems, catheters, and endoscopes.

In the optical communication industry, they provide high-speed transmission FPCs for integration into optical modules central to communication infrastructure worldwide.
In the automotive sector, Yamashita offers FPCs that meet demanding environmental requirements—such as heat resistance, thermal dissipation, and oil resistance. Their product lineup includes “Big Elec” FPCs for high-speed transmission and high-current applications.

Yamashita Material is suitable for what kind of FPC projects?

It is suitable for FPC projects where you want to consult from short-term prototyping to design and component mounting.

  • Urgent projects for prototypes and small-batch production
    They handle prototype and small-lot production from a single unit, making them a convenient contact for evaluation during development or for urgent additional orders.
  • Projects with unconfirmed FPC specifications or design data
    You can consult with us even if you don't have DXF or Gerber data, or if the optimal board specifications have not yet been determined.
  • A project that I'd like to request, from FPC manufacturing to component mounting, all in one go.
    This is suitable when you want to proceed without dividing into multiple vendors, as we handle everything from pattern design and FPC manufacturing to component procurement and assembly.

Checklist before consulting Yamashita Materials

You can consult with us even if the drawings and specifications are undecided. The following, organized to the extent possible, will help to facilitate discussions.

  • Product applications and the role required of FPCs
  • Approximate shape, size, and number of layers of FPC
  • Where to bend, the usage environment, and required performance
  • Documents such as drawings, circuit diagrams, DXF/Gerber data, and handwritten notes
  • Required quantities and desired delivery dates for prototyping and mass production
  • Whether to mount parts, which parts to mount, and whether to request parts procurement
  • Quality and inspection requirements

Specifically, for items where the specifications are not yet decided, it becomes easier to start considering them if you communicate "What kind of FPC is it for?" and "What kind of issues do you want to solve?".
