Understanding Inline PCB Router Machines and Why They Matter
An inline PCB router machine is designed to integrate PCB/PCBA depaneling directly into automated production lines, combining board loading, cutting, and unloading into a single continuous workflow. For electronics manufacturers running high-volume SMT lines, this approach removes manual handling steps between processes, reduces waiting time, and supports consistent cutting quality across large production batches. SEPRAYS, a brand under Dongguan Zhimao Automation Equipment Co., Ltd., has focused on PCB/FPC depaneling equipment and SMT automation since the company was founded in 1993, and its inline router machine lineup reflects more than three decades of accumulated experience in mechanical design, motion control, vision systems, and automation integration.
The SEPRAYS Inline Router Machine Lineup
SEPRAYS offers a broad range of inline PCB router machines under its GAM series, each tailored to different cutting sizes, production requirements, and board handling configurations. The lineup includes the GAM320AT, GAM330AT, GAM340AT, GAM360AT, GAM336AT, GAM336AL, GAM336AX, GAM336XL, GAM310AT, GAM300AT, GAM385AT, GAM380AT, GAM386AT, GAM386AD, and GAM386AL.
Core Technology Shared Across the Lineup
Most inline models in the GAM series are equipped with a high-speed ESD automatic tool-change spindle reaching a maximum speed of 100,000 rpm, along with a high-speed CCD vision alignment system for automatic position correction and precise cutting. Repeat precision across the series is typically ±0.01 mm, with cutting accuracy around ±0.05 mm, allowing stable performance even in continuous, high-throughput operation. Maximum moving speeds commonly reach XY: 1000 mm/s and Z: 800 mm/s, supporting efficient cycle times without sacrificing positioning accuracy.
Flexible Cutting and Handling Configurations
These machines support straight-line, L-shape, U-shape, circle, and arc cutting paths, accommodating a wide variety of PCBA panel designs. Loading is typically performed via track delivery, while unloading can be configured with belt delivery or track delivery depending on downstream equipment. Many models use vacuum nozzle absorption for PCB transfer, and several, such as the GAM336AT, GAM336AL, GAM336AX, and GAM336XL, feature a flexible single-head transfer supporting 0–180° rotation for PCBA pick-and-place, allowing adaptation to different upstream and downstream processes.
Addressing Different Production Needs
Compact and Standard-Size Applications
For smaller PCBAs, such as mobile phone boards, the GAM310AT provides a compact 200 × 180 mm valid cutting area with a dual transfer head design and anti-static belt feeding. The GAM320AT and GAM330AT offer a 350 × 300 mm cutting area with dual-worktable operation, suitable for standard production volumes.
Larger-Format and High-Capacity Needs
Manufacturers handling larger panels can select from the GAM340AT (450 × 420 mm), GAM336AL (450 × 420 mm), GAM336AX (510 × 460 mm), GAM336XL (650 × 460 mm), or the GAM360AT, which offers a large 620 × 550 mm valid cutting area with a single-worktable configuration designed specifically for large-format PCBA depaneling.
Carrier-Based and Downcut Applications
The GAM300AT is purpose-built for SMT full-carrier production lines, featuring a dual-layer track that supports automatic carrier flowing back, which helps reduce manual handling and supports board-edge-free processes, power adapters, and mobile phone-related products. For PCB/PCBA products with tall components on the top side, the GAM380AT, GAM385AT, GAM386AT, GAM386AD, and GAM386AL provide downcut routing structures. The GAM380AT and GAM385AT use fixture-free gripper-based handling supporting top-side component heights up to 45 mm, while the GAM386AT, GAM386AD, and GAM386AL use fixture-based downcut routing supporting top-side component heights up to 70 mm.
Quality and Efficiency Advantages
Documented Yield Improvement
SEPRAYS has worked with a global smartphone manufacturer facing high-density mainboard singulation challenges. By deploying the GAM386 downcut router, the manufacturer raised mainboard yield from 92.7% to 99.9%, directly addressing concerns around component cracking and damage from cutting stress, as well as the need for higher overall equipment effectiveness in high-volume SMT lines.
Dust Management and Continuous Operation
Dust collection structures vary by model, with options including top dust collection, bottom dust collection, or adjustable brush structures that accommodate different bottom-side component heights. Automatic tool change and, in many models, automatic broken router bit detection support continuous operation with minimal manual intervention, which is particularly valuable in lines running extended production cycles.
Software and Data Integration
Inline models run on a Windows 10 operating system with intuitive teaching by CCD color image input, simplifying programming for operators. Several models, including the GAM336AT series, support optional centralized MES management and data traceability, CCD barcode reading modules, laser height detection, router bit diameter detection, and post-cutting vision inspection, giving manufacturers flexibility to align the equipment with existing production-system interfaces.
Why Manufacturers Choose SEPRAYS
