TAISHIN

What TAISHIN does

TAISHIN (株式会社タイシン) is a privately held Japanese company founded in 1991 and headquartered in Takatsuki City, Osaka Prefecture. The company specializes in printed circuit board (PCB) design, manufacturing coordination, and assembly services for electronics manufacturers, with a particular focus on supporting advanced semiconductor interfaces including Intel CPUs (Amber Lake, Tiger Lake, Kaby Lake, ATOM), ARM processors, DDR5, USB 3.2, PCI Express, and HDMI. PCB design work is performed using OrCAD for schematic capture and CR-8000 DESIGN FORCE, CADVANCE αⅢ, and PCAD for board layout. The company operates with only 5 staff and coordinates prototype-to-mass-production PCB manufacturing through domestic and international partner fabs, while offering in-house PCB assembly capabilities covering BGA, CSP, and ball-less chip components down to single-unit volumes.

The company's proprietary software franchise is Ts Net Change EX, a multi-functional netlist conversion and comparison tool first released in February 2009 and continuously updated through version 4.3.0.0 (March 2026). The software addresses CAD interoperability across 42+ netlist formats (OrCAD, CR-8000, CADVANCE, KiCad, EAGLE, PADS, Mentor, Protel, START CAD, DesignSpark, etc.) and includes database-managed artwork CAD part name replacement, BOM creation, net comparison, coordinate data import, and net format prediction. An adjacent sub-brand, PCB Noah (プリント基板ノア), provides online automatic quotation and cloud-based PCB utility tools including impedance calculation, sheet surface optimization, and board yield calculation.

TAISHIN makes money through two principal streams: (1) project-based PCB design, manufacturing coordination, and assembly services billed to electronics manufacturers in the Kansai region, and (2) one-time perpetual software license fees for Ts Net Change EX, sold as either download (¥12,000-¥24,000) or USB memory (¥28,000) editions, with distribution handled directly through the company website and through channel partner 株式会社エイコ (Eicoh). The company is family-managed, led by President and Representative Director Shinichi Otani and Director Sanae Otani, with no external institutional investors, parent company, or subsidiary relationships.

Core offering

TAISHIN provides printed circuit board (PCB) design, manufacturing coordination, and assembly services for electronics manufacturers, alongside its proprietary Ts Net Change EX netlist conversion and comparison software that bridges multiple CAD platforms. The company supports the full lifecycle from single-unit prototypes to mass production, handling complex components such as BGA, CSP, and ball-less chips. Software is sold as either a download or USB version with perpetual licensing.

Product overview

TAISHIN (株式会社タイシン) is a Japanese company specializing in printed circuit board (PCB) design, manufacturing, and assembly services, complemented by proprietary CAD software products. The core product offering includes Ts Net Change EX, a multi-functional netlist conversion and comparison software that replaces CAD part names across different PCB design platforms, sold as either download or USB versions. The company also provides end-to-end PCB services including design (using OrCAD, CR-8000 DESIGN FORCE, PCAD), manufacturing (prototype to mass production through partner manufacturers), and assembly (handling BGA, CSP, ball-less chips from single units). An associated brand, PCB Noah (プリント基板ノア), offers online automatic quotation and cloud-based utility tools including net conversion software, board yield calculations, sheet optimization, and impedance calculation.

Scale indicators3 records

Recent moves7 records

Expansion highlights3 records

Emerging players

• PCBWay: Online PCB fabrication, assembly, and prototyping service offering rapid small-batch production. Comparable to TAISHIN's PCB manufacturing coordination and assembly services — both offer prototype-to-mass-production capability with low-volume agility.
• DipTrace: Affordable PCB design suite with schematic, layout, and component library features targeted at small and mid-sized projects. Comparable to Ts Net Change EX as an alternative paid PCB design tool, competing for the same budget-conscious designers in Japan and worldwide.
• EasyEDA: Browser-based PCB design tool with integrated fabrication ordering, serving hobbyists and small-scale designers globally. Comparable to TAISHIN's PCB Noah sub-brand and to TAISHIN's design services from a positioning standpoint, though EasyEDA bundles design with fabrication at low cost.
• JLCPCB: Large online PCB fabrication and assembly service offering low-cost rapid prototyping and small-batch assembly. Comparable to TAISHIN's PCB assembly arm as a price-aggressive alternative for the same single-unit BGA/CSP-capable small lot customer segment.
• KiCad: Open-source EDA suite for schematic capture and PCB layout, used widely by hobbyists and small OEMs. Comparable to TAISHIN's Ts Net Change EX because KiCad and open-source formats are explicitly supported by the software, while KiCad's free availability pressures TAISHIN's paid tooling economics.
• MacroFab: Online PCB assembly marketplace connecting engineers with vetted manufacturers for prototype-to-production runs. Comparable to TAISHIN's small-lot assembly capability (BGA, CSP, ball-less chips from a single unit) from a marketplace-vs-traditional-service business model perspective.

Direct peers

• Zuken Inc. Japanese-headquartered EDA vendor specializing in PCB and mechatronics design tools, including CR-8000 DESIGN FORCE — the same primary layout CAD used by TAISHIN. Both serve the Japanese PCB design market, making Zuken the most directly comparable peer despite being materially larger in scale and scope.

Broad incumbents

• Altium (Renesas Electronics): Leading PCB design software vendor (now a Renesas subsidiary) offering Altium Designer as a complete schematic-and-layout platform. Altium competes with TAISHIN's services by empowering engineers globally to perform PCB design in-house rather than commissioning an outside design house.
• Cadence Design Systems: Major EDA vendor and owner of OrCAD, the schematic capture tool that TAISHIN explicitly uses for its design services. Cadence competes indirectly by providing the underlying design suite that engineers could adopt in-house instead of outsourcing to TAISHIN's services arm.
• Siemens EDA (formerly Mentor Graphics): EDA division of Siemens AG offering PCB suites (PADS, Expedition, HyperLynx) that, like OrCAD and Altium, compete with TAISHIN's design services. Siemens EDA's CAD-format interoperability tools also overlap with Ts Net Change EX's multi-format conversion capability.
