PCB Vertical Cleaning System
Model STC-640 — vertical PCB cleaning system with space-saving vertical design, precision adhesive rollers, and intelligent static elimination for inline vertical conveyor production lines.
Vertical Space-Saving Design
Boards run on edge — suits lines already using vertical conveyors.
Precision Adhesive Rollers
Particle and dust removal at a roller pressure set for the board.
Intelligent Static Elimination
Eliminates surface static charge to prevent contamination-related defects.
Product Description
The PCB Vertical Cleaning System STC-640 runs boards through the cleaning path on edge rather than lying flat, which suits lines that already move boards on a vertical conveyor. Whether it fits a given layout is settled by the actual machine outline together with infeed and outfeed clearance and the access the rollers need for servicing — ask us for the outline drawing and check it against your floor plan.
Special precision adhesive rollers in vertical orientation provide effective particle and dust removal from PCB surfaces, while the intelligent static elimination system eliminates surface static charge. The quick-change window structure ensures fast maintenance for continuous production uptime.

Industry Applications
Application Scenarios
Space-Constrained SMT Production Lines
Compact electronics manufacturing facilities and high-density production layouts are limited in what they can give a cleaning station. The STC-640 processes boards on edge rather than flat, so the space it needs is arranged differently from a horizontal inline cleaner. Whether that arrangement works on your line is settled by the outline drawing, your infeed and outfeed clearance and the room to service the rollers — send us the space you have and we will check it.
SMT Pre-Print Cleaning
Before solder paste printing, PCB surfaces must be free of dust and particles that would contaminate the stencil or prevent solder paste from adhering correctly to pads. The STC-640 handles this pre-print cleaning stage in the SMT line; where it sits in the layout is confirmed from the outline drawing and the clearance your line can give it.
Retrofit Cleaning Integration
When adding a cleaning step to an existing SMT line without redesigning the layout, the on-edge orientation of the STC-640 is worth checking against the gap you have between existing stations. Send the available space and we will confirm it against the outline drawing, the infeed and outfeed clearance and roller service access.
Vertical vs Horizontal PCB Cleaning
The STC-640 carries boards through the cleaning path on edge; a horizontal inline cleaner lays them flat. That changes how the machine occupies the line, and it is the arrangement rather than any size figure that decides whether it fits: we publish no footprint for the STC-640 and no comparison model, so size it from the outline drawing together with your infeed and outfeed clearance and the access the rollers need for servicing. The other difference is that a board has to hold itself flat through a vertical transport; we publish no minimum stiffness, so send your board thickness and material and we will confirm whether the STC-640 suits it. For boards that cannot tolerate vertical transport, the horizontal STKF Series PCB Surface Cleaning Machine provides flat-bed transport. For SMT inline continuous cleaning, see the SMT600 Inline Cleaning Machine.
Frequently Asked Questions
What is the advantage of a vertical PCB cleaning system?
It runs boards through the cleaning path on edge instead of flat, so the space the machine needs is arranged differently along the line — which is what makes it worth checking on space-constrained SMT lines and retrofits where a horizontal cleaner will not go. We publish no footprint figure and no comparison model, so confirm the fit from the outline drawing plus your infeed and outfeed clearance and the room to service the rollers.
What PCB sizes can the STC-640 handle?
PCB size compatibility depends on the board's rigidity and dimensions. Contact us with your PCB dimensions and thickness specifications to confirm compatibility with the STC-640 vertical transport system.
Is the STC-640 suitable for flexible or ultra-thin PCBs?
A board has to hold itself flat through a vertical transport, and we publish no minimum stiffness for the STC-640. For flexible or ultra-thin PCBs the horizontal flat-bed STKF Series cleaner or an FPC-specific machine is the usual answer; send your board specification if you want the vertical option checked against it.
How does the cleaning method work in vertical orientation?
The STC-640 uses adhesive rollers in a vertical configuration with intelligent static elimination. Boards pass through the machine vertically, with rollers applying even cleaning pressure to both surfaces without contacting the PCB edges.
Can the STC-640 be integrated into an automatic SMT conveyor line?
Yes. The STC-640 is designed for inline integration with standard SMT conveyor systems. Conveyor height and board width specifications should be provided at the time of quotation to ensure compatibility.
What is the power requirement for the STC-640?
The STC-640 operates on 220V / 50Hz. For non-standard voltage requirements, contact us at the quotation stage.
