For electronics manufacturers evaluating a high precision PCB router machine, the central question is simple: can the equipment deliver tight cutting tolerances, protect sensitive components, and keep pace with high-volume SMT production without driving up labor costs? SEPRAYS, a brand under Dongguan Zhimao Automation Equipment Co., Ltd. that has focused on PCB/FPC depaneling technology since the company’s founding in 1993, provides a useful case study for answering that question through its GAM series router depaneling machines.

Precision Metrics That Define the Category

A high precision PCB router machine is ultimately judged by a handful of hard numbers. SEPRAYS’ technology platform reports a cutting accuracy of ±0.02mm and a repeatability of ±0.01mm, supported by high-speed spindles up to 80,000 RPM and CCD vision auto-correction at 15x magnification with auto-focus for real-time path correction. These specifications directly address two of the most common pain points in PCBA depaneling: component cracking and damage from high cutting stress, and misalignment defects caused by inconsistent positioning. According to the company’s internal comparison data, SEPRAYS equipment can achieve more than 30% higher hourly output under comparable operating conditions, a result attributed to self-developed control software, motion-control technology, modular electrical design, and long-term manufacturing experience.

Dual-Table Design and Throughput

One of the defining architectural choices across the GAM series is the dual-table design, which enables simultaneous cutting and loading. This configuration reduces idle time between cycles and supports higher SMT line utilization, which matters for manufacturers trying to solve the problem of low overall equipment effectiveness in high-volume SMT lines. Models such as the GAM360AT and GAM386 are built around this principle, combining the dual-table structure with the same high-speed spindle and CCD vision system found across the platform.

The GAM386 Downcut Router: A Documented Yield Case

Among the GAM series, the GAM386 downcut router stands out for a specific, documented outcome. For a global smartphone manufacturer, the GAM386 downcut router raised mainboard yield from 92.7% to 99.9%. The downcut routing design is specifically suited to PCB assemblies with taller components on the upper side, a configuration that conventional upcut routing can struggle to handle without damaging components. This single case illustrates how a high precision PCB router machine’s design choices translate directly into measurable production outcomes rather than abstract specifications.

The GAM386 itself is equipped with a high-speed CCD vision alignment system for automatic position correction, an automatic tool-change spindle to reduce manual tool-change operations, a precision screw-rod drive system for high-speed, high-precision movement, and automatic broken router bit detection to support reliable, continuous cutting. Its dual-worktable design reduces waiting time during loading and unloading, while intuitive CCD color image teaching simplifies programming and path setup. A safety light curtain provides additional operator protection, and the machine supports a robotic arm I/O interface, along with optional functions such as external cutting inspection, laser height measurement, post-cut visual inspection, barcode scanning, router bit diameter detection, and central control system integration.

Breadth of the GAM and ZM Series

Beyond the GAM386, SEPRAYS offers both offline and inline PCB router depaneling machines across the GAM series and ZM series, covering a wide range of valid cutting sizes, worktable configurations, and spindle arrangements. Offline models range from the compact GAM310A and GAM300 to larger-format machines like the GAM330X and ZM300NL, while inline models such as the GAM320AT, GAM336AT, and GAM380AT support automated loading, routing, and unloading for continuous production environments. Depending on the 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, and automation-line integration. This range allows manufacturers to match machine selection to PCB dimensions, production capacity, and automation requirements rather than forcing a one-size-fits-all approach.

Manufacturing Depth and Certification

The confidence behind these precision claims is grounded in the company’s operational scale and quality infrastructure. SEPRAYS has accumulated more than 30 years of experience in PCB/FPC depaneling equipment development and manufacturing, with capabilities spanning mechanical design, equipment development, motion-control applications, vision systems, electrical control, and automation integration. The company holds ISO 9001, ISO 14001, ISO 45001, and CE Certification, alongside more than 180 patent certificates. Manufacturing takes place across two facilities totaling more than 26,000 square meters, supported by a workforce that includes an 80+ person R&D team and a 100+ person technical engineering team.

Market Recognition and Customer Base

SEPRAYS’ PCB depaneling machine sales have ranked among the top three in the Chinese market, a position first reached in 2015 and reaffirmed in later company materials. More than 3,000 well-known enterprises have selected SEPRAYS and maintained long-term cooperation, spanning industries including automotive electronics, consumer electronics, EMS/ODM, new energy, medical electronics, computers, security, storage, and IoT. Representative customers in automotive electronics include Bosch, BYD, Valeo, CRRC, and Great Wall Motor, while consumer electronics and EMS/ODM customers include Apple, Foxconn, Flex, Luxshare, Xiaomi, OPPO, and HONOR.

Service Infrastructure Supporting Equipment Performance

A high precision PCB router machine is only as reliable as the service network behind it. SEPRAYS maintains domestic service coverage across 9 cities and international sales and service coverage across 31 countries, providing training, technical service, and after-sales assistance. This infrastructure supports customers through equipment implementation, programming, and ongoing maintenance, which is particularly relevant for machines like the GAM386 that rely on automatic tool-change spindles and CCD vision systems requiring periodic calibration and support.

Summary

For manufacturers searching for a high precision PCB router machine, the combination of ±0.02mm cutting accuracy, ±0.01mm repeatability, dual-table throughput design, and a documented yield improvement from 92.7% to 99.9% on the GAM386 downcut model provides a concrete, data-backed basis for evaluation. Supported by 30+ years of manufacturing experience, 180+ patents, and a service network spanning 31 countries, SEPRAYS’ GAM and ZM series represent a technically substantiated option for PCBA depaneling applications ranging from automotive electronics to high-volume consumer electronics production.
