Miniaturized PCBAs require more precise handling and positioning within a smaller working area.

The following steps can help you quickly determine which PCB router machine is suitable.

1. What Matters Most for Miniaturized PCBAs?

When selecting a PCB router machine for miniaturized PCBAs, focus on four areas:

PCBA Size → Stable Placement → Positioning Accuracy → Worktable Compatibility

The machine should provide a working area and positioning method that match the actual size of the product.

For smaller PCBAs, a compact machine can often provide a more suitable production setup than an oversized platform.

2. Use This Simple 4-Step Selection Method

A practical selection process can be simplified into four steps:

Step 1 → Confirm PCBA Size
Step 2 → Check Stable Placement and Positioning
Step 3 → Confirm Worktable Compatibility
Step 4 → Match the Machine to Production Volume

These four checks can quickly narrow down the suitable machine type before comparing detailed specifications.

3. Check Stable Placement and Worktable Size

For miniaturized PCBAs, confirm that the board can sit securely on the worktable during routing.

The worktable should match the product size closely enough to support consistent positioning.

If vacuum nozzle absorption is used, the vacuum layout should also be suitable for the actual PCB or PCBA dimensions.

A suitable worktable and stable vacuum positioning are especially important for smaller boards.

4. Check Positioning Accuracy and Repeatability

Smaller PCBAs often have less available routing margin, so positioning accuracy becomes especially important.

CCD vision positioning can help identify the board position before cutting, while good repeatability helps maintain the same routing path during continuous production.

When evaluating the machine, pay attention to:

• positioning method;
• cutting precision;
• repeat precision;
• consistency during repeated routing.

The smaller the routing margin, the more important accurate positioning becomes.

5. Check the Routing Path and Router Bit Size

The routing path and router bit size should match the actual contour and spacing of the miniaturized PCBA.

This is mainly a compatibility check to ensure that the cutting tool can follow the required path correctly.

6. Match the Machine to Your Production Method

The suitable machine structure also depends on production requirements.

For miniaturized PCBAs, the machine should match the actual product size and production flow rather than simply using the largest available platform.

7. SEPRAYS GAM310AT for Miniaturized PCBAs

GAM310AT In-Line Automatic PCB Router Machine

The SEPRAYS GAM310AT is designed for smaller PCB and PCBA products and provides a compact cutting area for automated production.

• Cutting area: 200 × 180 mm
• Vacuum nozzle absorption
• Repeat precision: ±0.01 mm
• Cutting precision: ±0.05 mm
• Router bit size: Ø0.8–3.0 mm
• CCD color vision positioning

The compact working area is well suited to manufacturers mainly processing smaller PCBAs while still requiring accurate positioning and automated routing.

For miniaturized PCBA production, the GAM310AT provides a compact machine structure with the positioning and cutting accuracy required for smaller products.

8. Conclusion and Next Step

For miniaturized PCBAs, focus on PCBA size, stable placement, positioning accuracy, worktable compatibility, and production method.

Provide SEPRAYS with your PCBA dimensions, board layout, cutting path, and production volume so the machine configuration can be evaluated correctly.
