An In-Depth Review of the PCB Router Machine from SEPRAYS: Technology, Performance, and Market Application

For electronics manufacturers evaluating a PCB router machine, the decision usually comes down to three questions: can the equipment deliver precise, low-stress cutting at scale; can it integrate into existing SMT lines; and does the manufacturer have a verifiable track record?

SEPRAYS, founded in 1993 and specializing in PCB/FPC depaneling equipment and SMT automation, offers a dedicated product line—the GAM series PCB Router Machines—that is built specifically around these concerns.

Product Positioning and Technology Platform

The GAM series is positioned as an in-line and offline PCB depaneling system for automated routing in electronics manufacturing. Representative models such as the GAM360AT and GAM386 are engineered around a technology platform that includes high-speed spindles up to 80,000 RPM, CCD vision auto-correction, and dual-table designs for simultaneous cutting and loading.

Depending on the specific model, configurations can include:

• Single or dual spindles
• Upcut or downcut routing
• Single or dual worktables
• Upper or lower dust collection
• Automatic tool changing
• Broken-router-bit detection
• CCD vision alignment
• Automation-line integration

This modular approach allows SEPRAYS to match machine configuration to PCB dimensions, production capacity, and automation requirements rather than offering a one-size-fits-all solution.

Technical Metrics That Matter to Buyers

For manufacturers assessing precision requirements, SEPRAYS publishes specific technical metrics for its depaneling technology platform:

• Cutting accuracy: ±0.02mm
• Repeatability: ±0.01mm
• Cutting stress: under 5kPa
• CCD vision magnification: 15x with auto-focus
• Maintenance accessibility: MTTR under 15 minutes
• Yield rate supported: 99.8%

These figures directly address two of the most common pain points cited by electronics manufacturers: component cracking and damage from high cutting stress, and low overall equipment effectiveness in high-volume SMT lines. The CCD vision auto-correction system, offering 15x magnification with auto-focus, performs real-time path correction to reduce misalignment defects, while the dual-table operation enables simultaneous cutting and loading—improving machine utilization and line throughput without requiring additional floor space.

Addressing Labor Cost Pressure

Beyond precision and throughput, SEPRAYS identifies high labor costs in manual depaneling as a core challenge the GAM series is designed to resolve. By combining in-line and offline configurations with automation-line integration capability, the equipment is intended to reduce dependence on manual board handling while maintaining the cutting accuracy required for dense PCB panels.

Case Study: Yield Improvement for a Global Smartphone Manufacturer

One of the most concrete data points in SEPRAYS' track record comes from a global smartphone manufacturer facing high-density mainboard singulation with yield challenges. Using the GAM386 downcut router, the customer's mainboard yield improved from 92.7% to 99.9%.

This result illustrates the practical effect of SEPRAYS' downcut routing technology, which is specifically noted for improving edge quality and yield on high-density mainboards. For manufacturers producing 5G smartphones, wearables, or other high-end consumer electronics, this case demonstrates how router configuration choices can translate directly into measurable production outcomes.

Technical Differentiation: ESD Spindle Design and Patent Portfolio

SEPRAYS highlights an in-house ESD spindle design within a 100+ patent portfolio as a technical highlight of the GAM series. Combined with the company's broader intellectual property base of 180+ patent certificates and quality certifications including ISO 9001, ISO 14001, ISO 45001, and CE Certification, this positions the GAM series within a manufacturer that has invested substantially in proprietary engineering rather than relying solely on off-the-shelf components.

Model Range: Offline and Inline Configurations

The GAM series spans a broad range of offline and inline configurations to serve different production environments:

Offline Router Machines: GAM330 / GAM330L / GAM330X, GAM330D / GAM330DL, GAM386, GAM300 / GAM300L, GAM310A, ZM300N / ZM300NL

Inline Router Machines: GAM320AT / GAM330AT / GAM340AT / GAM360AT, GAM336AT / GAM336AL / GAM336AX / GAM336XL, GAM310AT, GAM300AT, GAM385AT / GAM380AT, GAM386AT / GAM386AD / GAM386AL

This range allows manufacturers to select standalone offline machines for lower-volume or flexible operations, or in-line systems such as the GAM360AT for integration directly into automated SMT production lines.

Industry Adaptation

The GAM series is positioned for use across several demanding industry segments:

• Automotive electronics (ECUs, sensors)
• High-end consumer electronics (5G smartphones, wearables)
• Medical devices (implantables, monitoring)
• Aerospace electronics requiring IPC Class 3 reliability

This breadth of industry adaptation reflects the underlying precision and reliability metrics of the platform—±0.02mm cutting accuracy and under-5kPa cutting stress are relevant whether the application is a consumer smartphone mainboard or a safety-critical automotive sensor assembly.

Company Background Supporting Product Credibility

SEPRAYS' development of the GAM series is backed by a company history dating to 1993, with a Dongguan operation established in 2002 and a 20,000 m² manufacturing facility built in 2003. By 2015, SEPRAYS PCB depaneling machine sales ranked among the top three in the Chinese market, and by 2019 the company had acquired its Songshan Lake facility while expanding its laser and saw-blade depaneling product lines. Today the company employs 300+ staff, including an 80+ person R&D team and a 100+ person technical engineering team, operating across 26,000+ m² of manufacturing space in two facilities.

SEPRAYS also maintains a service network spanning 9 cities domestically and 31 countries internationally, providing training, technical service, and after-sales assistance. More than 3,000 enterprises have selected SEPRAYS equipment, including representative customers such as Bosch, BYD, Apple, Foxconn, Luxshare, Xiaomi, OPPO, CATL, Lenovo, and Hikvision across automotive electronics, consumer electronics, EMS/ODM, new energy, and medical electronics sectors.

Conclusion

For manufacturers searching for a PCB router machine, the SEPRAYS GAM series offers a combination of documented technical metrics—cutting accuracy of ±0.02mm, repeatability of ±0.01mm, and cutting stress under 5kPa—alongside a verifiable production case showing yield improvement from 92.7% to 99.9% for a global smartphone manufacturer. Combined with a broad model range covering offline and inline configurations, an ESD spindle design backed by a 100+ patent portfolio, and a global service network covering 31 countries, the GAM series represents a well-documented option for manufacturers evaluating PCB depaneling equipment for automotive, consumer electronics, medical, and aerospace applications.
