Fully In-House Domestic Production with Fine-Pitch Capability
Sanyo handles everything from design to implementation in-house, with all materials and manufacturing conducted domestically. Backed by over 40 years of experience, they support extremely fine-pitch FPCs and can meet complex or custom specifications that other companies may decline.
Customized Ultra-High-Resolution PCBs with Advanced Processing
Using subtractive methods, electroless plating, and semi-additive techniques, Sanyo provides customized ultra-high-resolution PCBs. BVH (Blind Via Hole) connections are also available. Chemical etching and micro-polyimide etching allow for highly flexible and cost-effective micro-hole processing.
Cost-Effective and Flexible for Design Changes
By avoiding the need for molds and optimizing material usage, Sanyo keeps production costs low. Their fully integrated in-house process also enables them to respond swiftly and flexibly to design changes, such as material selection or color variations.

Sanyo's Track Record
Proven Track Record Across a Wide Range of Applications, Including Inspection Equipment
- Semiconductor inspection systems; test equipment; LCD panel inspection devices.
- Substrates for magnetic heads; relay boards for optical pickups; actuator boards; relay boards for micro speakers and receivers; relay and terminal boards for other compact electronic components.
- Interconnection cables between circuit blocks (for applications without repetitive bending stress)
What kind of FPC projects is Sanyou suited for?
This is suitable for projects where we want to bring high-definition and custom-specification FPCs to life through consultation from the design stage.
-
Projects requiring fine wiring and miniaturization
It would be easy to consult with them when you want to discuss detailed processing conditions, such as high-definition wiring, fine lands, BVH, and fine holes/narrow slits.
-
Projects that want to try small-scale prototyping
This is suitable for development projects where you want to proceed with evaluation using prototypes first, as we support prototyping even from a single unit.
-
A project with specifications that are not yet fully solidified.
This is a company that you can consult with from the rough sketch and memo stage, making it easy to engage them when considering FPC specifications or construction methods.
-
A project that we want to proceed with with mass production in mind after the trial production.
This is also suitable when you want to consider the balance of quality and cost, with an eye on the flow from prototyping and evaluation to mass production.
Checklist before consulting SANYO
You can consult with us even if not everything is decided. If you can organize the following to the best of your ability, our meeting will proceed more smoothly.
- Product uses and what you want to achieve with FPC
- Approximate shape, size, and number of layers of FPC
- Current materials such as drawings, rough sketches, and memos
- Desired conditions such as wiring pitch, hole diameter, bending method, and material
- Required quantities for prototyping and mass production
- Desired delivery date and schedule for evaluation and mass production start
- What is important to you in terms of quality (durability, manufacturability, operating environment, etc.)?
- Cost conditions and priorities
If the conditions are undecided, even just stating "what kind of product it will be used for" and "what is the problem you are facing" can make it easier to connect with us for consultation on specifications and construction methods.
