Product Overview
Automated Stencil Cleaning for SMT Production
BC320 integrates aqueous cleaning, DI water rinsing and hot-air drying into one automated process for common SMT cleaning tasks.
- Solder Paste Stencils
- Red Glue Stencils
- Copper Stencils
- Misprinted PCBs
- Squeegees
- PCBA
Integrated Process
A Clear, Repeatable Cleaning Sequence
A five-step workflow brings aqueous washing, DI water rinsing and hot-air drying together in one BC320 cycle.
02
Aqueous Wash
Water-based cleaning liquid is sprayed onto the stencil.
03
DI Water Rinse
DI water rinses remaining cleaning residues.
04
Hot Air Dry
Hot-air drying removes residual moisture after rinsing.
05
Unload
Remove the cleaned, dried stencil after the cycle.
Working Principle
Two Media Loops, One Integrated Process
Wash liquid and DI water follow separate circulation paths, each with 1 μm filtration and recovery back to its respective tank.
WASH LOOP
- Cleaning liquid
- Pump
- Spray nozzles
- Stencil
- 1 μm filtration
- Liquid recovery
RINSE LOOP
- DI water
- Pump
- Spray nozzles
- Stencil
- 1 μm filtration
- Water recovery
↗Hot Air Drying follows the wash and DI water rinse stages.
Engineered Cleaning System
Key Design Features of the BC320
The BC320 combines its cleaning, rinse, filtration, drying and control functions in one machine platform.
Fixed Spray Rods
Four fixed cleaning spray rods support the wash process.
Fixed Air Knives
Four fixed air knives are part of the machine design.
Moving Stencil Mechanism
The stencil moves during cleaning as part of the mechanism.
Real-Time Filtration
Cleaning liquid and DI rinse water use 1 μm filtration.
Separate Media Systems
Wash liquid and DI water follow separate process paths.
Hot-Air Drying
Hot air blow drying is specified up to 90°C.
PLC Control
PLC-controlled cleaning procedures are operated from the panel.
Touch-Screen Interface
English color touch-panel operational interface.
Automatic Liquid Handling
Wash liquid and rinse water can be added and discharged automatically.
Observation Window
A large right-side observation window makes the process visible.
Machine Structure
Three Main Process Modules
Wash
Water-based cleaning liquid is sprayed onto the stencil. Cleaning time and liquid temperature can be adjusted.
Rinse
DI water rinses remaining cleaning residues. Rinse time and water temperature can be configured.
Dry
Hot-air drying removes residual moisture after rinsing. Drying time and hot-air temperature can be adjusted.
