PCB Surface Cleaning Before Solder Paste Printing<\/h1>\n\n\n\n
Dust, fibers and loose particles can remain on bare PCBs after storage, handling or board loading. Static electricity can attract additional contamination before the PCB enters the solder paste printer.<\/div>\n\n\n\n
DEZ PCB surface cleaning equipment removes dry contamination and static from both sides of bare PCBs before printing. The cleaner installs between the PCB loader and solder paste printer without adding a separate manual cleaning step.<\/div>\n\n\n\n

\n

Poor Contact Between PCB and Stencil<\/h2>\n\n\n\n
Particles between the PCB and stencil can create local gaps that affect solder paste transfer during printing.<\/div>\n<\/div>\n <\/div><\/div>\n<\/div><\/div><\/div>\n\n\n\n
\n
\n
\n

Contamination Transferred to the Stencil<\/h2>\n\n\n\n
Cleaning the PCB before printing reduces the transfer of loose particles from incoming boards to the underside of the stencil.<\/div>\n<\/div>\n <\/div><\/div>\n<\/div><\/div><\/div>\n\n\n\n

Recommended PCB Surface Cleaning Equipment<\/h2>\n\n\n\n

Double-Sided PCB Cleaning Machine DEZ-C753S removes dust, fibers, loose particles and static from both sides of bare PCBs before solder paste printing.<\/p>\n\n\n\n

Brushes loosen surface contamination. Ionized air reduces static, vacuum sections extract released particles, and sticky rollers collect remaining contamination before the PCB enters the printer.<\/p>\n\n\n\n

The machine processes bare PCBs from 50 \u00d7 50 mm to 350 \u00d7 350 mm with a thickness of 0.4\u20133 mm. It supports left-to-right or right-to-left transfer and connects with standard SMT production equipment at a conveyor height of 900 \u00b125 mm.<\/p>\n\n\n\n

PCB Surface Cleaning FAQ<\/h2>\n\n\n\n
\n
Is this process used for bare PCBs or assembled PCBAs?<\/div><\/span><\/span><\/span><\/div>
\n

It is used for bare PCBs before solder paste printing and component placement.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Can the machine remove flux residue after soldering?<\/div><\/span><\/span><\/span><\/div>
\n

No. Post-solder flux residue requires a dedicated PCBA cleaning process<\/a>.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

What contamination can be removed?<\/div><\/span><\/span><\/span><\/div>
\n

The system removes dry surface contamination such as dust, fibers and loose particles. It also reduces static before particle collection.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Does the machine clean both sides of the PCB?<\/div><\/span><\/span><\/span><\/div>
\n

Yes. The DEZ-C753S is configured to clean the upper and lower surfaces of the bare PCB.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Where is the cleaner installed in the SMT line?<\/div><\/span><\/span><\/span><\/div>
\n

It is normally installed after the PCB loader and before the solder paste printer.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Does the process use water or cleaning chemicals?<\/div><\/span><\/span><\/span><\/div>
\n

No. The DEZ-C753S uses brushes, ionized air, vacuum extraction and sticky rollers for dry PCB surface cleaning.<\/p>\n<\/div><\/div><\/div>\n<\/div>\n<\/div>\n <\/div><\/div>\n\n\n\n

Send us the PCBA dimensions, soldering method, flux information, component layout, contaminated areas, production volume and required cleaning result.

PCBAs containing actual post-solder residue can be tested before machine selection. DEZ will evaluate whether the application requires single-sided cleaning, offline batch cleaning or continuous inline cleaning.<\/p>\n<\/div>\n\n\n\n
