How to Use the Nozzle Overview Matrix for Nozzle Selection

The Nozzle Overview Matrix is a comprehensive cross-reference tool that maps every Ersa selective soldering nozzle configuration by base type, height, and ID/AD dimensions. This step-by-step guide shows you how to use the matrix to find the exact nozzle part number you need, quickly and accurately.

Key Takeaways

**Start with your base type** — B14.1/B22 or B16.1/B36 determines which matrix section to use

**Find your height row** — H=47 is most common; extended heights are available for specific needs

**Locate your ID/AD column** — matches your required solder contact width

**The intersection gives your part number** — order by part number for fastest service

**Use the Part Number Lookup tool** — for quick search by reference number

Step 1: Identify Your Base Type

The first and most critical step is determining which base type your machine uses. The matrix has separate sections for B14.1/B22 and B16.1/B36 — they are NOT interchangeable.

How to Identify Your Base Type

MethodHow to Check

|---|---|

Machine manualLook for B14.1, B22, B16.1, or B36 designation Solder pot inspectionMeasure the seating diameter and thread pattern Current nozzleIf your existing nozzle fits, the base type matches Photo verificationSend us a photo — we can confirm the base type

Remember: B14.1 and B22 are the same base type (legacy vs. current naming). B16.1 and B36 are also the same base type. But B14.1/B22 and B16.1/B36 are different and not interchangeable.

Common Machines by Base Type

Base TypeCommon Machines

|---|---|

B14.1/B22VERSAFLOW 2/3, ECOSELECT 1/2, SMARTFLOW 1/2/3 B16.1/B36VERSAFLOW 4 (some), ECOSELECT (some), SMARTFLOW (some)

Step 2: Determine Your Required Height

Nozzle height (H value) determines how far the solder wave extends above the pot surface. Choose based on:

FactorImpact on Height Selection

|---|---|

PCB thicknessThicker boards may need taller nozzles Fixture or carrier heightTall fixtures raise the PCB above the pot Component stand-offBottom-side components that block wave access Solder pot surface levelCurrent solder level in the pot

Height Availability

For B14.1/B22:

HeightID/AD Range AvailableMost Common Application

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

H=471.8/2.5 to 31.0/35.0 (39 configs)Standard, most widely used H=572.5/5.0 to 10.0/14.0 (7 configs)Thick boards H=622.0/4.5 to 8.0/12.0 (7 configs)Medium extended H=752.4/5.0 to 10.0/14.0 (8 configs)Deep wells H=803.0/6.0 to 10.0/14.0 (11 configs)Tall fixtures H=852.6/5.6 to 6.0/10.0 (8 configs)Very tall fixtures H=904.0/8.0 to 8.0/12.0 (3 configs)Maximum extension

For B16.1/B36:

HeightID/AD Range AvailableAvailable Configs

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

H=472.5/4.0 to 12.0/16.08 configs H=563.0/4.5 and 4.0/8.02 configs H=583.0/6.01 config H=754.0/8.01 config H=854.0/8.02 configs H=904.0/8.0 to 6.2/10.04 configs

Step 3: Select Your ID/AD Dimensions

ID/AD determines the solder contact area on your PCB:

**ID (Inner Diameter)** — The opening where solder emerges. Determines contact width.

**AD (Outer Diameter)** — The outer dimension. Determines how close the nozzle can approach adjacent components.

Step 4: Find Your Part Number in the Matrix

Navigate to the [Nozzle Overview Matrix](/technical-guides/ersa-selective-soldering-nozzle-overview-matrix) page and:

1. **Go to the correct base type section** — B14.1/B22 or B16.1/B36

2. **Find your height column or row** — e.g., H=47

3. **Locate your ID/AD value** — e.g., 4.0/8.0

4. **Read the part number at the intersection** — e.g., 114611 for H=47, ID/AD 4.0/8.0, B14.1/B22

Matrix Navigation Example

You need a nozzle for:

Machine: VERSAFLOW 3/45 (B14.1/B22 base)

Height: H=47 (standard)

ID/AD: 6.0/10.0 (large pads)

Result: Part number **114613** — found at H=47 row and ID/AD 6.0/10.0 column in the B14.1/B22 section.

Step 5: Verify and Order

After finding your part number:

1. **Cross-check the specification** — Confirm the ID/AD, height, and base type match your requirement

2. **Search by part number** — Use our [Part Number Lookup](/part-number-lookup) tool for quick verification

3. **Order by part number** — This is the fastest and most accurate ordering method

4. **Custom option** — If your ID/AD and height combination shows no part number (empty cell), contact us for a custom nozzle

What If the Matrix Cell Is Empty?

An empty cell in the matrix means that specific ID/AD and height combination is not available as a standard nozzle. Options:
