Selective wave soldering Machine for PCB selective soldering and DIP selective soldering through Mini wave soldering with Nitrogen (N2) selective solder Equipment 

KZXH20 Desktop selective wave soldering

Machine Features
Compact Desktop Design: Compact size, footprint significantly smaller than traditional in-line wave soldering machines, making it ideal for space-constrained locations such as laboratories, R&D centers, and small- to medium-volume production lines. High-Precision Three-Axis Motion System: A precision X, Y, and Z servo motor drive system ensures the solder wave nozzle can precisely position each solder joint on the PCB, with positioning accuracy reaching ±0.05mm or better. Micro Selective Solder Wave: The core component is a nozzle that produces a stable, micro solder wave. This micro wave targets only the specific points to be soldered, avoiding immersing the entire board in solder. Integrated Flux Applicator: This system is often equipped with a spot-spray fluxing system, also controlled by a program, that precisely applies a small amount of flux to the desired solder joints, avoiding contamination of other areas. Nitrogen Shielding Option: Many high-end models offer an optional nitrogen shielding system. Injecting nitrogen into the solder wave crest effectively prevents solder joint oxidation, significantly improving solder joint quality, resulting in brighter, more uniform solder joints and reduced dross. Programming and Vision Alignment System: Equipped with graphical programming software for easy operation, solder paths can be quickly generated by importing Gerber files or using teach mode. Select high-end models are equipped with a vision positioning system that automatically identifies mark points, compensates for PCB positioning errors, and ensures soldering accuracy. Flexible Parameter Control: Parameters such as soldering time, solder volume, and preheat temperature can be individually set for each solder joint to meet the process requirements of different components and pads.

Product specification

Applications:

1. Automotive Electronics
This is the largest application area for selective wave soldering. Automotive electronics have extremely stringent reliability requirements and must withstand harsh environments such as high temperature, vibration, and humidity.

2. Industrial Control and Automation
Industrial equipment typically requires 24/7 uninterrupted operation, placing extremely high demands on the stability and lifespan of circuit boards.

3. Aerospace and Defense
Products in these sectors have stringent requirements for weight, reliability, and performance under extreme conditions. Any soldering defect can have catastrophic consequences.

4. Medical Electronics
Medical equipment is directly related to human life and health, requiring extremely high safety and long-term stability.

5. Communications Equipment
Communications equipment, particularly core network equipment, must process large amounts of data and ensure long-term, trouble-free operation.

6. High-End Consumer Electronics and Computing Technology
While not all consumer electronics require selective wave soldering, some complex, high-value products utilize selective wave soldering to process specific through-hole components.

Why do these industries choose selective wave soldering for their products?:

The advantages of selective wave soldering precisely meet the needs of the aforementioned industries:

High reliability: Localized soldering reduces thermal stress and minimizes impact on sensitive surface-mount components (such as BGAs), significantly reducing defects such as cold solder joints and bridging.

Handling complex boards: It can solder circuit boards with tall, densely packed components, or mixed technology (through-hole + SMD) that cannot be protected using traditional wave soldering fixtures.

Welding high-quality through-hole connections: For through-hole components requiring strong mechanical connections or high current carrying capacity (such as connectors, large capacitors, and transformers), selective wave soldering provides more consistent and reliable solder joints than manual soldering.

High flexibility: Suitable for high-mix, low-volume production models, with fast programming changeover speeds, it is ideal for industries with rapid product updates.

In short, selective wave soldering is a key process in high-end electronics manufacturing and a key indicator of an electronics factory's technical capabilities and product quality.
