Ersa VERSAFLOW Nozzle Configuration Guide: Setup Per Model

The Ersa VERSAFLOW series is one of the most widely deployed selective soldering platforms in electronics manufacturing. Understanding the nozzle configuration options for each VERSAFLOW model is essential for achieving optimal solder joint quality and production throughput. This guide covers nozzle base types, ID/AD selection, and setup recommendations for every VERSAFLOW variant.

Key Takeaways

**VERSAFLOW models use either B14.1/B22 or B16.1/B36 base types** — you must match your solder pot exactly

**H=47 is the standard height for most VERSAFLOW configurations** — extended heights available for thicker boards

**ID/AD selection depends on pad size and component density** — smaller ID for fine-pitch, larger for connectors

**VERSAFLOW 2 and 3 series primarily use B14.1/B22** — with 90+ nozzle configurations available

**VERSAFLOW 4 series may use B16.1/B36** — 18 configurations for the larger base type

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

VERSAFLOW Model Overview

B14.1/B22 Nozzle Configurations for VERSAFLOW

The B14.1/B22 base type is the most common across VERSAFLOW machines. It offers 90+ nozzle configurations spanning multiple heights and ID/AD combinations.

Recommended Starting Nozzle Set

For a new VERSAFLOW production line, we recommend starting with this core nozzle set:

Part NumberID/ADHeightApplication

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

1146093.0/6.0H=47Fine-pitch components, small pads 1146114.0/8.0H=47Standard through-hole pads 1146136.0/10.0H=47Medium pads, most versatile 1186158.0/12.0H=47Wide connectors 11927410.0/14.0H=47Extra-wide connections

These five nozzles cover 80% of typical selective soldering applications on VERSAFLOW machines.

Extended Height Nozzles for Thick PCBs

When your PCB or fixture requires more wave extension:

Setting Up Nozzles on VERSAFLOW Machines

Step 1: Identify Your Solder Pot Base Type

Before installing any nozzle, verify your solder pot base type:

Check your machine documentation for B14.1/B22 or B16.1/B36 designation

Examine the physical solder pot — the seating dimensions differ between base types

B14.1/B22 and B16.1/B36 are NOT interchangeable — using the wrong base type causes poor seating and unstable solder flow

Step 2: Select Nozzle ID/AD Based on Your PCB

Match the nozzle ID to your pad dimensions:

Measure the target pad width on your PCB

Choose an ID that provides 1-2mm solder contact beyond the pad edge

For fine-pitch components (spacing less than 2mm), use smaller ID nozzles (1.8/2.5 or 2.5/4.0)

For large connectors, use wider ID nozzles (8.0/12.0 or 10.0/14.0)

Step 3: Determine Height Based on Fixture Design

The nozzle height must accommodate:

PCB thickness

Fixture or carrier board height

Component stand-off on the bottom side

Solder pot surface level

H=47 works for most standard setups. If your fixture raises the PCB significantly above the solder pot, consider H=57, H=75, or H=85.

Step 4: Install and Verify

1. Insert the nozzle into the solder pot and ensure it seats firmly

2. Start the solder pump and observe the wave height and shape

3. Verify the wave contacts the target pads without touching adjacent components

4. Adjust the nozzle position or change ID/AD if the solder contact area is too wide or too narrow

VERSAFLOW Nozzle Maintenance

Maintaining your VERSAFLOW nozzles ensures consistent production quality:

**Daily**: Wipe down nozzle tips and remove surface dross

**Weekly**: Clean with IF930 paste and appropriate brushes

**Monthly**: Check ID/AD dimensions for wear and plan replacements
