The Semiconductor Cleaning Machine AC-420 is a precision cleaning system designed for semiconductor chip packaging and electronic component assembly processes. The equipment removes flux residues, organic contamination, and process debris after soldering, bonding, and packaging operations.

In semiconductor backend manufacturing, cleaning performance directly affects package reliability. Residual flux, particles, and chemical contamination may lead to poor electrical performance, corrosion, adhesion problems, and long-term reliability failures.
The AC-420 provides an automated cleaning solution combining spray cleaning, rinsing, and drying processes to improve cleanliness and production consistency for semiconductor package manufacturing.
What is Semiconductor Cleaning Machine AC-420?
The AC-420 is a semiconductor package cleaning machine used after chip assembly and soldering processes. It is designed to clean packaged semiconductor devices before inspection, testing, or final assembly.
Unlike wafer cleaning systems used in front-end semiconductor fabrication, the AC-420 focuses on backend packaging applications where assembled chips require contamination removal.
Typical applications include IC packages, semiconductor modules, lead frames, and electronic components requiring high cleanliness before the next production stage.
Why Chip Packaging Cleaning is Important
During semiconductor packaging, different manufacturing steps can introduce contaminants including:
Flux residues from soldering
Organic contamination
Metal particles
Dust and process debris
Chemical residues
These contaminants may cause:
Electrical leakage
Package corrosion
Poor bonding performance
Adhesion failure
Reduced reliability
Effective cleaning after assembly helps manufacturers maintain stable product quality and improve package lifetime.
AC-420 Semiconductor Cleaning Technology
Spray Cleaning System
The AC-420 uses spray cleaning technology to remove contamination from semiconductor packages. High-pressure cleaning fluid reaches package surfaces and removes residues generated during assembly processes.
Flux Residue Removal
Flux residues are commonly generated during soldering processes. If not removed properly, they may create corrosion risks or reduce package reliability.
The AC-420 is designed to provide effective flux cleaning for semiconductor assembly applications.
DI Water Rinse Process
After chemical cleaning, DI water rinsing removes remaining cleaning agents and improves surface cleanliness.
Hot Air Drying
The integrated drying process removes remaining moisture and prepares semiconductor packages for inspection or downstream assembly.
