Ersa SMARTFLOW Nozzle Options: Sizes, Setup and Compatibility

The Ersa SMARTFLOW series represents Ersa's latest generation of compact, high-speed selective soldering machines designed for fast cycle times and flexible production. Understanding the nozzle options for SMARTFLOW ensures you select the right configurations for your specific soldering requirements. This guide covers available nozzle sizes, base type compatibility, and setup recommendations.

Key Takeaways

**SMARTFLOW machines use B14.1/B22 or B16.1/B36 base types** — verify your specific model before ordering

**SMARTFLOW 3.0 is the most common model** — with B14.1/B22 as the primary base type

**Compact solder pot design favors H=47 standard height** — extended heights available for specific needs

**Fast cycle times require optimal nozzle selection** — wrong nozzle size slows production throughput

**All replacement nozzles are aftermarket compatible** — brand names used only to indicate machine compatibility

SMARTFLOW Nozzle Setup Tips

Optimizing for Fast Cycle Times

SMARTFLOW machines are designed for high-speed production. Nozzle selection directly impacts cycle time:

1. **Choose the smallest ID that covers your pad** — smaller nozzles create faster, more focused solder waves

2. **Avoid oversized nozzles** — too-wide solder contact slows the process and risks bridging

3. **Use standard height (H=47) when possible** — the wave reaches optimal height fastest at standard height

4. **Pre-heat optimization** — proper flux and preheat reduce the dwell time needed at each solder point

SMARTFLOW Dual Station Setup (SMARTFLOW 4.0)

On SMARTFLOW 4.0 with dual stations:

Configure each station with a different nozzle size for mixed-component boards

Assign fine-pitch soldering to one station and connector soldering to the other

Each pot can run at different solder temperatures if needed

Ensure each nozzle matches its respective pot base type

Nozzle Selection Quick Reference

Match nozzle ID to pad width for optimal SMARTFLOW performance:

Pad Width (mm)Recommended ID/ADExpected Solder Contact Width

|---|---|---|

1-21.8/2.5~2.5mm contact 2-32.5/4.0~4mm contact 3-43.0/6.0~6mm contact 4-64.0/8.0~8mm contact 6-86.0/10.0~10mm contact 8-108.0/12.0~12mm contact 10+10.0/14.0~14mm contact

SMARTFLOW Nozzle Maintenance

Fast cycle times mean more solder cycles per day, accelerating nozzle wear:
