AC460 Bare PCB Surface Cleaning Machine

Product Overview

The AC460 Bare PCB Surface Cleaning Machine is an inline PCB surface cleaning system designed to remove dust, lint, particles, copper scraps and electrostatic charge from bare PCBs before entering critical assembly processes such as solder paste printing, adhesive dispensing or coating.

Installed after laser marking and before solder paste printing or adhesive coating, the AC460 combines vacuum cleaning, tacky roller particle collection and ionized static elimination to ensure a cleaner PCB surface and a more stable downstream process.

During PCB transfer, the machine uses a self-adhesive tacky dust roller to efficiently capture micro-particles, contaminants, fibers and residues generated during electronics manufacturing. At the same time, the built-in ionizing static elimination system neutralizes residual electrostatic charge on the PCB surface, reducing the risk of foreign particle reattachment, printing defects, soldering failures and hidden reliability issues.

The AC460 is an ideal solution for manufacturers seeking to improve solder paste printing quality, reduce contamination-related defects, minimize rework and enhance overall PCB assembly yield.

Key Features of AC460 PCB Surface Cleaning Machine

1. Inline Bare PCB Surface Cleaning Before Critical Processes

AC460 is designed for inline installation directly after laser marking and before solder paste printing, glue dispensing or adhesive coating. It helps ensure that the PCB enters the next process in a clean and electrostatically neutral condition.

2. Vacuum + Tacky Roller Cleaning for Effective Particle Removal

The system combines vacuum suction with a high-efficiency tacky roller cleaning mechanism to remove:

• Dust
• Fine particles
• Lint and fibers
• Copper scraps
• Debris generated during PCB handling or laser marking
• Other surface contaminants that may affect printing and assembly quality

The tacky roller transfers contaminants to the tacky paper roll for centralized collection, helping maintain a stable and repeatable cleaning effect.

3. Built-In Static Elimination System

Residual static electricity on PCB surfaces can attract dust and cause quality problems in downstream assembly. AC460 is equipped with an ionizer-based static elimination system that effectively neutralizes static charge on the PCB surface, helping to:

• Prevent dust re-adsorption
• Reduce solder paste printing defects
• Lower the risk of component damage caused by ESD
• Improve process stability in sensitive electronics manufacturing environments

4. Improves Printing Quality and Assembly Yield

By removing contamination and static before printing, AC460 helps reduce process defects such as:

• Solder paste printing contamination
• Poor paste release or incomplete printing
• Foreign material induced soldering defects
• Cold solder joints and insufficient soldering
• Hidden quality failures caused by particle contamination

This contributes to higher first-pass yield, lower rework rate and more consistent product quality.

Why PCB Surface Cleaning Matters Before Solder Paste Printing

In SMT and PCB assembly lines, bare PCB surfaces often carry dust, fibers, copper residues and electrostatic charge after storage, transport, handling or laser marking. If these contaminants are not removed before solder paste printing or adhesive coating, they may lead to:

• Poor solder paste printing consistency
• Solder bridging or insufficient solder
• Reduced solder joint reliability
• Component placement instability
• Increased defect rate and rework cost
• Long-term hidden reliability risks in finished electronic products

The AC460 is engineered to solve these problems at the source by providing inline PCB cleaning before the contamination reaches the printing process.
