Offline PCBA Cleaning Machine for Batch Flux Removal – DEZ-C743

Manual wiping can remove visible contamination from open surfaces, but it cannot consistently control cleaning chemistry, rinsing quality or contamination underneath components.

The DEZ-C743 processes multiple SMT, THT or mixed-technology assemblies in one batch. Chemical spray washing, DI-water rinsing and hot-air drying are completed inside the same enclosed chamber without transferring the PCBAs between stages.

It is designed for high-mix, small- to medium-volume production that requires a complete aqueous cleaning process but does not need a large inline system.

What the PCBA Cleaning Machine Does and Why Choose It

The C743 removes compatible water-soluble flux, rosin flux, selected no-clean flux residue, solder paste residue, fingerprints, dust and loose particles from assembled circuit boards.

Upper, middle and lower spray positions direct heated cleaning liquid towards both loading levels. DI water then rinses away dissolved residue and remaining cleaning agent before hot-air drying.

It can process SMT, THT and mixed-technology assemblies after reflow, wave, selective or manual soldering.

Problems the PCBA Cleaning Machine DEZ-C743 Solves

PCBA Cleaning After Soldering

Removes flux residue and process contamination from SMT and THT assemblies after soldering.

Cleaning Before Conformal Coating

Washes, DI-rinses and dries PCBAs before conformal coating is applied.

High-Mix Batch Production

Allows different PCBA models to use the same offline cleaning machine and separate process settings.

Replacing Manual Cleaning

Completes washing, rinsing and drying without moving wet assemblies between separate tanks.

DEZ-C743 PCBA Cleaning Suitable Applications

The C743 is suitable for batch PCBA cleaning across a wide range of industries, including automotive electronics, medical electronics, industrial controls and power electronics, telecommunications equipment, and EMS manufacturing. It can clean automotive control boards, sensor assemblies, medical instrument PCBAs, industrial controllers, power supplies, inverter PCBAs, communication control boards, and network equipment, while handling assemblies with both SMT and through-hole components.
For EMS factories, the C743 can also serve as a shared offline cleaning station for samples, small batches, and frequently changing production orders, supporting post-solder cleaning, DI-water rinsing, and drying.

Select the Correct PCBA Cleaning Equipment

Automatic Single Sided PCBA Cleaning Machine DEZ-C758
Use the DEZ-C758 when visible flux marks and loose solder balls are concentrated on one accessible solder-side surface. The machine uses cleaner application, wet brushing, dry brushing and fan drying.
Inline Water-Based PCBA Cleaning Machine DEZ-C1360
Use an inline water-based model when PCBAs must pass continuously through chemical washing, DI-water rinsing and hot-air drying. The DEZ-C1360 is designed for continuous conveyor production.

FAQs by C743 PCBA Cleaning Machine

What does the DEZ-C743 clean?

It cleans compatible flux residue, solder paste residue, electroplating salts, fingerprints, dust and loose particles from assembled circuit boards.

Yes. Spray arms are positioned above, between and below the two-level basket to direct liquid towards PCBAs on both loading levels.

Yes. It can clean compatible residue from THT assemblies after wave or selective soldering, including contamination around accessible leads and solder joints.

Some no-clean flux residues can be removed using a compatible cleaning agent and validated process settings. Sample testing is required because no-clean flux formulations differ.

The quantity depends on each board’s dimensions and loading arrangement. The basket measures 610 × 560 × 100 mm and supports a combined product weight of up to 10 kg.

Yes. DI water is used during the rinsing stage. The specified inlet requirement is 0.3 m³/h with resistivity above 15 MΩ·cm.

Yes. Washing time, rinsing time, drying time and temperature settings can be adjusted through the touchscreen.

Installation requires AC 380 V power, compressed air, DI water, drainage and an exhaust connection.

Yes. The automatic filling system is available as an optional configuration.

Yes. Send the sample boards, flux information, contamination photographs and acceptance requirements. DEZ can establish and verify the cleaning process using the actual assembly.
