1. Component Essence
Part Number Correspondence:

C76036: Primary Wave Nozzle (Smooth Wave / Turbulent Wave)

C76037: Secondary Wave Nozzle (Turbulent Wave / Chip Wave)

The image shows one set (usually the C76036 primary wave nozzle, structurally perfectly matched)

Official Name: Wave Former Assembly / Wave Nozzle Assembly
Physical Features:
Multi-hole jet plate with densely packed round holes: Controls the solder spray pattern, forming a stable and uniform solder wave peak
Integrated stainless steel / titanium alloy cavity: Resistant to high-temperature corrosion of lead-free solder (SAC305), preventing solder dross accumulation
Side mounting and positioning structure: Quick-plug fixing, adaptable to the solder bath wave peak cavity mounting position
Guide channel design: Guides solder backflow, reducing wave peak vibration

2. Compatible Models

Delta Series: Delta 3, Delta 5. Delta X, 6622 CC Full Series Wave Soldering

Installation Location: Wave generation area inside the solder pot. C76036 main wave first, C76037 auxiliary wave second. The PCB passes through both waves sequentially to complete the soldering process.

Material 316L Stainless Steel / Titanium Alloy (Lead-Free) 316L Stainless Steel / Titanium Alloy

Nozzle Specifications Φ2.0~Φ3.0mm Round Hole, Hole Spacing 5~6mm Φ1.5~Φ2.5mm Round Hole, Closer Hole Spacing

Wave Type Flat Wave / Turbulent Wave (Main Soldering Wave) Turbulent Wave / Chip Wave (Pre-soldering, De-bubbling)

Suitable Solder Temperature 230~280℃ (Lead-Free SAC305) 230~280℃

Installation Method: Quick-plug fixation of the solder bath wave crest cavity; Series installation with the same main wave.

Core Function: Forms a stable, wide-amplitude wave crest for batch PCB soldering; disperses air bubbles on solder pads, improves wetting effect, and reduces bridging.

Function and Working Principle:

Core Function: The solder wave generator in wave soldering propels molten solder from the solder bath upwards through a multi-hole jet plate, forming a solder wave that meets process requirements. The PCB board passes through the wave crest along the track, completing the batch soldering of through-hole components.

Dual-Wave Coordination Logic:

C76037 Auxiliary Wave (Turbulence Wave): Pre-solders the PCB pads, breaking up air bubbles between pads, improving flux wetting effect, and reducing bridging and cold solder joints.

C76036 Main Wave (Flat Wave): Forms a stable, smooth, wide-amplitude wave peak to complete the final soldering, ensuring full and bright solder joints.

1. Original Factory Procurement (ITW EAE Authorized Channel)

Part Numbers: C76036 (Main Wave), C76037 (Auxiliary Wave)

100% Original Factory Matching, with Warranty, No Modification Required

Customization Requirements: Completely matches cavity size, nozzle specifications, and installation positioning structure.

Preferred Material: Titanium Alloy (lead-free operating life is 2-3 times that of stainless steel).

Nozzle Accuracy: ±0.05mm, ensuring consistent wave peak shape.

Troubleshooting and Maintenance

1. Common Faults
Unstable Wave Peaks/Jitter: Nozzle blockage (solder dross accumulation), cavity deformation, impeller wear.

Soldering Bridging / Cold Solder Joints: Nozzle wear, insufficient wave height, slag buildup in the guide channel
Solder Solder Leakage: Aging of the cavity seal, loose installation positioning
Shortened Lifespan: Use stainless steel nozzles in lead-free solder environments (prioritize titanium alloy).

2. Maintenance and Replacement
Daily Maintenance: Weekly shutdown for disassembly, clean the nozzles with a dedicated solder slag removal tool, and flush the cavity with solder pot cleaner to prevent clogging.
Replacement Cycle:
Stainless Steel: 6–12 months (lead-free conditions)
Titanium Alloy: 18–24 months (lead-free conditions)
Replacement Criteria: Nozzle wear > 0.2mm, abnormal wave shape, decreased soldering yield
