1. Product Overview

The DezSmart DEZ-H3500A is a advanced 3-axis (3-axis linkage) selective wave soldering machine designed for high-precision PCB (Printed Circuit Board) welding. As an all-in-one offline model, it integrates selective fluxing and soldering functions on a compact XYZ motion table, making it ideal for space-constrained production environments .

Controlled entirely by an industrial PC, all parameters—including soldering temperature, flux type, movement path, and nitrogen temperature—can be set, saved, and traced via software, ensuring consistent and repeatable welding quality . Its flexible design allows seamless integration beside production lines, adapting easily to diverse manufacturing setups .

2. Application Scope

The DEZ-H3500A excels in scenarios requiring precise, selective soldering, making it indispensable across electronics manufacturing sectors:

Consumer Electronics: Welding PCBs in smartphones, laptops, and wearables.
Automotive Electronics: Handling complex circuit boards in car infotainment systems and sensors.
Industrial Electronics: Assembling control panels and communication equipment with dense component layouts.
Medical Devices: Ensuring reliable solder joints in precision medical instruments.

It supports PCBs of varying thicknesses (0.2mm–6mm) and maximum sizes up to L350×W410mm (customizable for larger boards), catering to diverse production needs .

4. Core Advantages

The DEZ-H3500A stands out with features that redefine efficiency and precision in selective soldering:

All-in-One Compact Design: Combines fluxing and soldering on a single XYZ platform, saving space compared to separate systems .
Superior Welding Quality: Titanium-alloy solder pots with uniform heat transfer (via external heating plates) and nitrogen heating reduce oxidation, ensuring strong, consistent joints .
Full Traceability: PC-based control stores all parameters (temperature, speed, path) in configurable files, enabling easy quality tracking and repeatability .
Precise Motion Control: 3-axis stepper motors with ball screws and linear guides ensure ±0.1mm positioning accuracy, low noise, and smooth movement—critical for dense PCB layouts .
Flexible Production Integration: Can be placed beside lines for on-demand welding, adapting to dynamic production schedules better than rigid inline systems .

5. Product Structure

The DEZ-H3500A’s robust structure combines key systems for reliable performance:

Control System: Industrial all-in-one PC with Windows 10-based software, enabling path programming via PCB images and real-time monitoring of critical parameters (temperature, pressure, speed) .
Motion System: Lightweight 3-axis (X, Y, Z) platform with stepper motors and drivers, ensuring fast, stable movement .
Fluxing System: Includes a jet valve (adapting to various fluxes) and a stainless steel pressure tank for consistent application .
Soldering System: Features a leak-proof titanium-alloy solder pot, 5 standard alloy nozzles (customizable), and an inline nitrogen heater to enhance wetting and reduce dross .
Machine Chassis: Steel-welded frame with a thick base plate, minimizing vibration for stable operation .

6.Work Case

A leading automotive electronics manufacturer adopted the DEZ-H3500A for welding sensor PCBs with dense components:

Challenge: Traditional wave soldering caused bridging (unwanted connections) on small-pitch pins.
Solution: The DEZ-H3500A’s selective nozzles targeted only required (solder joints), with programmable parameters ensuring precise flux and solder application.
Result: Defect rates dropped by 35%, while nitrogen integration reduced solder dross by 40%, cutting material costs.

The DezSmart DEZ-H3500A redefines selective wave soldering with its compact design, traceable controls, and precision engineering—ideal for electronics manufacturers seeking quality, flexibility, and efficiency.
