PDK Co., Ltd.
Founded in 1968, Print Denshi Kenkyujo (PDK) is a seasoned manufacturer that also specializes in flexible PCBs. Below is an overview of their technical specs and key strengths.
Key Features of PDK’s Flexible PCBs
Experience with over 1,000 types of PCBs
experience
With over 1,000 types of PCB production under their belt since their founding in 1968, PDK has a long history of handling both standard and specialized boards. They offer a one-stop service from design to assembly, and can accommodate anything from prototyping to medium-volume production. They’ve even successfully taken on projects that other companies declined.
Wide variety of flexible PCB types
PDK operates more than 50 manufacturing machines, enabling them to produce everything from large-sized and extra-long flexible PCBs to FPCs and rigid-flex boards. Each project is preceded by a thorough review of specs and processing methods to optimize both cost and quality.
Open to consultation and customization
While they offer standardized formats, PDK encourages clients to consult them about any unique specifications. For instance, their standard max sizes are 1,000×1,200mm (large) and 500×2,000mm (long), but they have experience fabricating PCBs longer than 30,000mm.

Why Choose PDK?
Manufacturers who will give you advice
PDK is not just a supplier of off-the-shelf products—they’re a manufacturer willing to adapt to each customer’s unique requirements. Their flexible approach makes them a reliable choice for tailored FPC needs.
What kind of FPC projects are suitable for Print Electronics Research Laboratory?
This is suitable for consultation projects regarding FPCs that are difficult to manufacture with standard specifications, such as large, long, or custom-spec FPCs.
-
Projects requiring large-sized and long FPCs
Because it supports the manufacturing of large and long boards, it is easy to consult with them when you need FPCs that do not fit standard sizes or when you want to integrate long wiring.
-
Project to prototype a custom-specification FPC
It also supports micro-machining, multi-layer FPCs, and flex-rigid boards, and you can consult with them about boards that are difficult to manufacture with standard specifications.
-
A project for which we would like to proceed with production from small quantities
We handle everything from prototyping to small-lot mass production, making it ideal for cases where you want to produce and evaluate in small quantities first and then proceed to the next stage based on those results.
-
A project that I would like to consult on, including design and implementation.
Because you can consult not only on PCB design and manufacturing but also on assembly, it is a candidate for consultation when you want to consider specifications including the manufacturing method.
Checklist before consulting Print Electronics Laboratory
You can consult with us even if the specifications are not fully finalized. Organizing the information and materials you have at this point will make it easier to proceed with evaluating manufacturability and discussing specifications.
- Products and applications that use FPCs, and any current challenges you are facing
- Desired PCB type, such as single-sided, double-sided, multilayer, or rigid-flex
- Approximate size, number of layers, and thickness of the circuit board
- Desired specifications, such as trace width, trace spacing, and hole diameter
- Documents such as Gerber files, CAD data, and PDFs showing the product's appearance
- If you also request design and implementation, the schematic, parts list, and board outline drawing
- Planned quantities for prototyping and mass production, respectively
- desired delivery date, specified conditions such as materials and processing methods
You can consult with us even at a stage when drawings or specifications are not yet finalized by sharing the information currently available. Especially for large and long FPCs, the sizes we can handle vary depending on the specifications, so it is a good idea to organize the current dimensions and configuration beforehand.
