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.

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.
