In the field of electronics manufacturing, stencil cleaning efficiency directly determines production line capacity. Traditional manual cleaning or cleaning with electric equipment takes 5 to 10 minutes per part, while the pneumatic spray technology equipped on Dezheng Intelligent’s DEZ-C730 fully pneumatic stencil cleaning machine compresses single-batch cleaning time to 1 to 4 minutes, increasing efficiency by over 300%. This article combines the equipment’s core technology with real-world industry data to analyze how it redefines the benchmark for SMT cleaning efficiency.Lorem ipsum dolor sit amet, consectetur adipiscing elit.

1. Efficiency Revolution: The underlying logic of “hours” to “minutes”
▎Three bottlenecks of traditional cleaning
- Mechanical contact is inefficient: brushes/ultrasonic waves must be cleaned repeatedly, and it takes more than 5 minutes to clean mesh sizes below 0.1 mm;
- Uncontrolled solvent consumption: Open tanks consume 500–1000 ml of liquid at a time, and the time spent refilling them accounts for 20% of total working hours;
- Manual intervention is cumbersome: pressure must be manually adjusted and the liquid level monitored, and a single process operation takes more than 8 minutes.
▎The Solution for Pneumatic Spraying
Fully Pneumatic Drive System
- Compressed air of 0.45-0.7 MPa directly drives the nozzle, eliminating motor startup/speed regulation time and increasing the response speed to 0.1 seconds;
- Without loss of electrical components, the equipment failure rate is reduced by 75% compared to electric models, reducing maintenance downtime.
360° Rotating Isobaric Jet
- Double-sided nozzles rotate at a high speed of 2,000 rpm, forming a constant water flow of 20 m/s. The coverage area of a single spray is 4 times larger than that of traditional nozzles;
- 0.02 mm Micro-gap Penetration: The cleaning volume that traditional processes would take 3 minutes to complete can be completed in 1 minute.
Efficiency comparison table
| Cleaning process | Traditional equipment | DEZ-C730 (pneumatic spray) | Improvement |
|---|---|---|---|
| Single piece cleaning time | 5-10 minutes | 1-4 minutes | 300% |
| Daily processing capacity (8 hours) | 48-96 pieces | 120-240 pieces | 150% |
| Manual intervention time | 2 hours/day | 0.5 hours/day | 75% |
2. Technological Update: Three Key Advances in Pneumatic Spraying
▎ Optimizing Fluid Mechanics: Balancing High Pressure and Energy Saving
- Dual-Mode Injection :
▶ Standard Mode (2-4 minutes): 0.5 MPa pressure is suitable for conventional steel mesh, and fluid consumption is 120-200 ml/piece;
▶ Speed Mode (1 minute): Short-term high-pressure impact of 0.7 MPa, for one-time cleaning of red glue/thick stencil (≤2.5 mm). - Three-stage filtration cycle :
1 mm primary filtration intercepts tin slag → 5 μm fine filtration removes solder paste particles → 1 μm nanofiltration adsorbs rosin, the cleaning fluid recycling rate reaches 95%, and only 500 ml of fresh fluid needs to be added every 8 hours.
▎ Structural Design Innovation: Evolution from “Equipment” to “System”
- Side Air Inlet Drying System :
Independent air path design, drying time is simultaneously compressed to 2-5 minutes, saving 30% in energy consumption compared to traditional front and rear air inlet systems; - Quick-Release Modular Structure :
Nozzles and filters can be quickly replaced in 30 seconds, increasing maintenance efficiency by 5 times and reducing losses caused by production line downtime.
▎ Intrinsic Safety Improvement: Risk-Free Efficiency Leap
- Fully Pneumatic Explosion-Proof Design :
Requires no power input, eliminating the risk of electric sparks from the root cause, passing ATEX explosion-proof certification and adapting to high-risk scenarios such as lithium batteries and automotive electronics; - Closed man-machine isolation :
One-touch operation and a fully sealed stainless steel cabinet reduce operator exposure to solvents by 90%, meeting ISO 45001 occupational health standards.
3. Actual Data: From "Theoretical Breakthrough" to "Production Line Verification"
▎Customer Case 1: Consumer Electronics Benchmarking Company
Pain Point: Cleaning the steel mesh (0.3 mm pitch QFP) on a mobile phone motherboard takes 8 minutes per piece, the daily production capacity is only 60 pieces, and labor costs account for 15%.
Solution: Use the DEZ-C730 pneumatic stencil cleaner in extreme speed mode (1.5 minutes per stencil) with a water-based cleaning agent.
Result:
- Daily production capacity increased to 320 pieces, with an annual increase of 73,000 pieces;
- Cleaning agent costs were reduced from RMB 650,000 per year to RMB 195,000 per year, a savings of 70%;
- The PCBA pad displacement defect rate was reduced from 0.8% to 0.15%, reducing rework losses by over RMB 1 million per year.
▎Customer Case 2: Leading Automotive Electronics Manufacturer
Challenge: The residual rate of automotive radar steel mesh (2.0 mm thick, red glue process) after cleaning exceeds 5%, requiring secondary manual cleaning.
Solution: Standard mode (3 minutes/piece) + three-stage filtration system, using solvent-based cleaning agents.
Data:
- The single cleaning pass rate reaches 99.2%, eliminating the need for a secondary cleaning process;
- A single device saves RMB 280,000 in labor costs per year and reduces compressed air consumption by 40%.
