PCB Cleaning Machines

Choose the Correct PCB or PCBA Cleaning Machine

Equipment selection depends on whether the board is bare or assembled, what contamination must be removed and whether production requires inline or offline cleaning.

Workpiece and cleaning requirement	Recommended equipment
Bare PCB with dust, fibres or loose particles before solder paste printing	Automatic Double-Sided PCB Cleaning Machine – DEZ-C753S
Assembled PCBA with visible residue or loose solder balls on one accessible solder side	Automatic Single-Sided PCBA Cleaning Machine – DEZ-C758
Assembled PCBA requiring continuous brush cleaning on one accessible side	Automatic PCBA Brush Cleaning Machine – DEZ-C760
Assembled PCBA requiring offline batch washing, DI-water rinsing and hot-air drying	Offline PCBA Cleaning Machine for Batch Flux Removal – DEZ-C743
Assembled PCBA requiring continuous aqueous cleaning after soldering	Inline Water-Based PCBA Cleaning Machine – DEZ-C1360
Aqueous PCBA cleaning process requiring a dedicated DI rinse-water source	Deionized Water System for PCBA Cleaning – DEZ-CS300

PCB Cleaning Applications by Industry

PCB surface cleaning before printing is used where dust, fibres and loose particles must be controlled before solder paste transfer.

For factories handling frequent product changes and different PCB sizes, see EMS and Contract Electronics Manufacturing.

For vehicle control boards, power modules and other automotive assemblies, see Automotive Electronics SMT Manufacturing.

For controllers, drives, power supplies and automation electronics, see Industrial Control SMT Manufacturing.

Frequently Asked Questions

What does a PCB cleaning machine remove?

The Automatic Double-Sided PCB Cleaning Machine – DEZ-C753S removes dust, fibres, hair, loose particles and static-attracted contamination from bare PCB surfaces before solder paste printing.

Is PCB cleaning the same as PCBA cleaning?

No. PCB surface cleaning normally refers to removing loose contamination from an unpopulated board before printing. PCBA cleaning treats an assembled or soldered board and may involve visible flux residue, loose solder balls or ionic contamination.

Can the Automatic Double-Sided PCB Cleaning Machine – DEZ-C753S remove flux residue?

No. It uses brushes, ionised air, vacuum extraction and tacky rollers for dry particle removal.

For flux residue after soldering, compare DEZ PCBA Cleaning Machines.

Does PCB surface cleaning require chemicals or DI water?

The DEZ-C753S uses a dry cleaning process and does not use an aqueous wash or DI-water rinse.

DI water is relevant to compatible aqueous PCBA cleaning processes after soldering. Where a dedicated rinse-water source is required, see the Deionized Water System for PCBA Cleaning – DEZ-CS300.

Where is the PCB cleaning machine installed?

It is normally installed after the PCB loader and immediately before the solder paste printer. The conveyor direction, fixed edge and production height must match the SMT line.

Should we send PCB samples before ordering?

Samples are recommended for thin PCBs, unusual surfaces, sensitive structures or difficult contamination. Testing helps confirm board transport and cleaning suitability before the final configuration is approved.

Request the Correct PCB or PCBA Cleaning Machine

Tell DEZ whether the workpiece is a bare PCB or assembled PCBA, what contamination must be removed and where cleaning occurs in production.

Include the board dimensions, production volume, required result, factory utilities and available samples. DEZ will recommend the appropriate cleaning process and equipment configuration.
