Flexible Support for Diverse Needs
—From a Single Board to Full Product Integration
At Seiken, in collaboration with our group company Shinano Seiken, we provide high-quality PCB design and assembly services tailored to your unique requirements. Whether you’re developing a one-off prototype or ramping up for mass production, our flexible support system ensures high-quality results—starting from just one board. We handle various assembly types, including surface-mount (SMT) and through-hole assembly, manual soldering, power circuit design, and even modification of existing PCBs. Both lead-free and eutectic solder lines are available to meet technical and compliance standards.
PCB Design & Reliable Assembling—Driven by Shinano Seiken Expertise.
PCB Design
With years of experience and accumulated know-how, we provide PCB designs optimized for low noise and high reliability. Our PCB design services are used across various industries—from medical devices to industrial systems. While design automation tools continue to evolve, the key to a truly effective board still lies in sound engineering and foresight during the initial design phase—qualities we bring to every project.
Power Circuit Design
We have extensive experience in power-related applications such as power conditioners and uninterruptible power supplies (UPS). Copper thickness, trace widths, and creepage distances are carefully calculated to ensure both performance and safety—even in compact layouts.
Digital & Analog Design
From measurement devices to medical equipment, we design boards for high-speed digital systems or sensitive analog applications. From impedance control to resonance suppression, our boards are built to support consistent, trouble-free operation.
PCB Assembly
From low-volume orders, we offer flexible assembly options to match your production goals. Every board is built with attention to detail—ensuring functionality, reliability, and repeatability, all with excellent cost-performance.
- SMT Assembly: Max board size: 380 mm × 540 mm, Minimum chip size: 0402
- Soldering: Supports both lead-free and eutectic solder
- Manual Mounting: Ideal for custom boards or designs without metal masks
- Hand-Soldering: Precise manual assembly of even 0402-sized components
Equipment Assembly & Wiring
We go beyond PCB mounting to offer fully integrated electronic equipment assembly—from initial component integration to meticulous wiring and system-level testing. With a strong track record across diverse sectors, including medical devices and industrial and medical systems, we bring precision, flexibility, and reliability to every stage of the assembly process.
