In SMT production, residual flux, solder balls, ink and dust left on PCBA boards after soldering are key factors affecting long-term product reliability. Incomplete cleaning can lead to electrochemical migration, corrosion and even short circuits in humid environments, directly threatening product quality and service life. How to efficiently and safely remove contaminants from soldered surfaces while protecting front-side components is a real challenge faced by many PCBA manufacturers.
The DEZ-C758 Inline Automatic PCBA Single-Side Brush Cleaning Machine from DEZSMART is a professional-grade cleaning solution designed to address this challenge. Featuring an inline fully automatic structure that combines PCBA board conveying technology with multi-directional brush cleaning technology, it provides an efficient and reliable cleaning solution for single-sided PCBA production in consumer electronics, communication equipment and industrial control applications.
1. Designed Specifically for Single-Sided PCBA – Protecting Front-Side Components
Many cleaning equipment on the market use immersion or spray methods, which can easily allow cleaning agents to penetrate into the front-side component areas, causing contamination or corrosion. The DEZ-C758, in contrast, adopts a targeted single-side cleaning design. Through a precision automatic cleaning agent coating system, it evenly applies cleaning agent only to the soldered surface. The brush cleaning structure is reasonably configured to ensure the cleaning agent never contacts front-side components. This design makes the equipment particularly suitable for precision PCBA products with high component density where front-side contamination is unacceptable.
2. Multi-Directional All-Around Scrubbing – No Dead Corners
The DEZ-C758 employs a combination structure of round brush + roller brush, performing multiple scrubbing passes in all directions – front, back, left and right. This ensures contaminants in every area of the PCBA board are thoroughly cleaned. Compared to traditional single-direction scrubbing equipment, this multi-dimensional scrubbing method removes stubborn residues around pad gaps and components more completely, effectively solving the problem of missed cleaning at board edges and corners.
3. Flexible Adjustability – Adapting to Various Board Types and Process Requirements
Different batches of PCBA boards vary in size, component height and contaminant types. The DEZ-C758 offers multiple adjustable parameters, allowing users to flexibly configure based on actual needs:
Broad board width adaptability: Supports PCBA boards from 50mm to 300mm in width
High component clearance: Supports component heights up to 135mm, offering strong compatibility
Stepless brush height adjustment: Adjustable from 0 to 20mm to match boards of different thicknesses
Stepless spindle speed adjustment: Continuously adjustable from 0 to 500 rpm to meet different contamination level requirements
Adjustable conveyor speed: Stepless adjustment from 0 to 1800 mm/min to match different production line paces
Whether quickly switching parameters in small-batch, high-mix production scenarios or running stably on high-speed mass production lines, the DEZ-C758 handles the job with ease.
4. Fully Automatic Operation – Labor-Saving and Hassle-Free
The DEZ-C758 features PLC intelligent control with a touchscreen HMI, making operation simple and intuitive. Key automatic features include:
Automatic cleaning agent coating: The coating system automatically applies cleaning agent, eliminating the need for manual contact with cleaning fluids and ensuring operational safety
Automatic conveying system: Supports both left→right and right→left transport directions (optional), enabling automatic connection with upstream and downstream processes
Automatic waste collection: Waste generated during cleaning is automatically collected in a filter box at the bottom of the machine for easy disposal
Spring-loaded gripper design: Thickened double spring-loaded grippers or heavy-duty grippers ensure the PCBA board does not shift during transport, maintaining cleaning precision
5. Anti-Static Brushes – Safe and Board-Friendly
The DEZ-C758 uses imported brown bristle brushes with anti-static properties, effectively removing solder balls and flux residue without scratching the PCBA board surface. For PCBA boards with board edges (minimum board edge thickness of just 1.5mm), the equipment can still securely clamp the boards, ensuring positioning accuracy throughout the cleaning process.

FAQ
Q1: Can the DEZ-C758 clean double-sided SMT PCBA boards?
The DEZ-C758 is specifically designed for cleaning the soldered surface of single-sided PCBA boards. The cleaning process does not wet the front-side components. For double-sided SMT PCBA boards, we recommend our double-sided cleaning models or alternative cleaning processes.
Q2: How is the equipment maintained? How often do the brushes need replacement?
Daily maintenance mainly involves periodically cleaning waste residue from the bottom filter box and checking that the cleaning agent lines are clear. Brush service life depends on cleaning frequency and board contamination levels. Typically, replacement is recommended every 6 to 12 months. It is advisable to check brush wear condition before each shift change and replace worn brushes promptly to maintain consistent cleaning performance.
Q3: Will there be residue or water stains on the board surface after cleaning?
The DEZ-C758 uses mechanical brush cleaning with cleaning agents. After cleaning is completed, PCBA boards are discharged directly through the conveying system. As the process does not involve high-pressure spraying or immersion, water stains do not form on the board surface. Follow-up drying or ion contamination testing is recommended to ensure the product meets IPC standard cleanliness requirements.
