GAM386AT Downcut PCB Router Machine

The GAM386AT is a fully automatic inline PCB router designed for fixture-based depaneling of PCBAs with tall top-side components.

Tall-Component PCBA Routing: Bottom-side routing accommodates top-side components up to 70 mm high.
CCD Vision Alignment: CCD positioning correction helps maintain accurate PCB routing.
ESD Automatic Tool Change: A high-speed ESD spindle supports automatic router bit replacement.
Fixture-Based Routing: Dedicated fixtures provide stable PCB support and positioning during depaneling.

Product Details

Overview

The SEPRAYS GAM386AT is an automatic downcut PCB router machine for inline PCBA depaneling after SMT assembly. It combines track loading, vacuum nozzle transfer, and dual worktables to route PCB panels along programmed cutting paths.

With automated board handling and fixture-based processing, the GAM386AT helps manufacturers manage high-component PCBA depaneling while reducing manual intervention between production stages.

Core Advantages

Dual-Table Efficiency

Two worktables and a movable cover allow one PCB to be prepared while the other is being routed, reducing waiting time between cutting cycles.

Low-Stress Loading

Elastic edge clamping on the infeed conveyor assists PCB positioning while reducing mechanical stress during transfer.

Tall-Component Clearance

Bottom-side routing provides clearance for top-side components up to 70 mm high, avoiding interference with the cutting mechanism.

Gentle Vacuum Handling

The vacuum nozzle assembly lowers in stages to reduce impact and mechanical stress when picking up PCB assemblies.

GAM385AT vs GAM386AT: How to Choose?

Both the GAM385AT and GAM386AT are SEPRAYS automatic downcut PCB router machines, but they are designed for different handling and positioning requirements. The right choice depends on component layout, fixture requirements, and PCB panel size.

GAM385AT | Flexible Gripping & Tray Loading

GAM385AT PCB Router

For flexible PCB handling and tray loading.

The GAM385AT uses grippers instead of the dedicated routing fixture system used by the GAM386AT. It is suitable for PCBA production requiring flexible gripping, rotation, and unloading.

Maximum cutting area: 500 × 450 mm.

GAM386AT | Fixture-Based Tall-Component Routing

GAM386AT PCB Router

For PCBAs with tall top-side components.

The GAM386AT uses dedicated fixtures to support PCB panels during bottom-side routing. It accommodates top-side components up to 70 mm, subject to bottom-side clearance and fixture requirements.

Maximum cutting area: 350 × 300 mm.

Selection Guide

Choose the GAM385AT when your priority is larger PCB panels, flexible gripping, product rotation, and tray-loading workflows.

Choose the GAM386AT when the PCB has tall top-side components and requires stable, fixture-based positioning during routing.

Both machines use downcut routing. The final choice should consider component heights on both sides, the cutting path, and mechanical clearance.

Application

The GAM386AT is suitable for automatic PCBA depaneling after SMT assembly, particularly in applications that require precise bottom-side routing.

Tall-Component PCB Assemblies

Suitable for PCBAs with top-side components up to 70 mm high. Bottom-side component height and clearance must also be considered when designing the fixture and cutting path.

PCB Panels with Different Cutting Profiles

Processes PCB panels with straight, L-shaped, U-shaped, circular, and curved routing paths, depending on the panel layout and programmed cutting route.

Inline SMT Production

Designed for automated PCB loading, depaneling, and unloading as part of an integrated SMT production workflow.

GAM386AT Downcut PCB Router Machine FAQ

1. What is the difference between a downcut PCB router and a conventional top-cut router?

The GAM386AT routes the PCB from underneath, leaving more clearance above the board for taller components.

2. What is the maximum component height supported by the GAM386AT?

The machine supports top-side components up to 70 mm. Bottom-side component clearance must be checked against the cutting mechanism and fixture design.

3. Why does the GAM386AT use dedicated fixtures?

Dedicated fixtures support and position PCB panels during routing, helping minimize board movement and maintain stable cutting conditions. Each fixture is designed around the PCB layout and cutting path.

4. How does the GAM386AT reduce mechanical stress during depaneling?

Elastic edge clamping, staged vacuum nozzle lowering, and precision routing mechanisms help reduce mechanical stress during PCB transfer, pickup, and cutting.

5. Does the GAM386AT support quick product changeovers?

Yes. Saved programs can be recalled, and barcode-assisted fixture identification helps operators select the corresponding routing program for repeat production.

6. Can the GAM386AT connect to MES systems?

SEPRAYS offers centralized equipment monitoring and production data collection solutions. Specific MES integration requirements should be confirmed according to your factory system.

7. What information is needed for a GAM386AT quotation?

Please provide your PCB panel dimensions, cutting path drawings or Gerber files, component heights on both sides, production capacity requirements, and upstream/downstream equipment details.
