I. Applicable Models
Selective Soldering: ZEVAm+, mySelective 6748, ZEi/A Series
Wave Soldering: Delta 5, Delta X Series
High-Frequency Spray/Spray Flux System
II. Structure and Function (Standard Configuration)
Main Tank + Refill Tank (Dual Tank Design)
Main Tank: Equipped with a level sensor/weighing module, low level alarm, and automatic refill.
Refill Tank: Automatic refilling during production without stopping the machine, increasing capacity.
Pressure Control: Constant air pressure (approximately 400 mbar) drives flux delivery.
High-Precision Flow Meter: Low flow monitoring (<1 µl/min), precise control of spray volume.
Filtration System: Prevents nozzle clogging (compatible with 180 µm spray orifice).
Material: PP/PE corrosion-resistant plastic or stainless steel, compatible with no-wash, lead-free, and water-based fluxes.
Capacity: Commonly 0.5L–2L (depending on model)
III. Key Features
Stable Feeding: Closed-loop control, level/pressure/ Flow monitoring throughout the process
Anti-bubble and anti-sedimentation: Reduces uneven spraying and missed areas
Quick changeover and easy cleaning: Compatible with various flux switching options
N₂ seal optional: Anti-oxidation, extends flux life
IV. Model and Procurement (Original/Replacement)
Original parts: Order through ITW EAE distributors, with complete PN (e.g., 6748 series spare parts)
Accessories: Level sensor, pressure regulating valve, filter element, seals
V. Common Problems and Maintenance
Leakage: Replace seals, check joints
Inaccurate level: Clean/calibrate sensor
Clogged nozzles: Replace filter elements regularly, clean with a special cleaning agent
Unstable feed: Check air pressure, exhaust, pump/valve
VI. Information You Need to Provide (Precise Matching)
Equipment model (e.g., ZEVAm+ / mySelective 6748), part number
Capacity, interface size, material (PP / stainless steel)
Single tank / double tank, whether with weighing/level indicator, N₂ interface
