DEZSmart DEZ-C750 Electric Stencil Cleaning Machine
1. Industry Context: Printing Determines Success
The solder paste printing process is one of the most vital stages in PCB assembly. Statistics show that 70% of mounting defects originate from the printing process. Maintaining a pristine SMT stencil is the ultimate key to improving printing quality.
2. The Pain Points of Traditional Methods (Manual IPA)
While manual wiping with Isopropyl Alcohol (IPA) is common, it presents several risks:
Incomplete Cleaning: As component density increases and pitches narrow, manual wiping fails to completely remove solder paste or particles from tiny apertures.
Quality Defects: Blocked apertures lead to insufficient or excess solder, causing failure in later production stages.
Safety & Compliance: IPA is a flammable solvent with low cleaning power. It requires strict storage regulations and incurs high long-term costs.
Future Difficulty: As apertures continue to shrink, cleaning solder paste will become even more challenging for manual methods.
3. The Automated SMT Cleaning Machine Solution
Compared to manual IPA cleaning, automated machines significantly reduce residual solder particles. For stubborn residues in small apertures, a professional automated

5.FAQ
Q1:What soldering defects can result from incomplete stencil cleaning?
A1:Solder paste residue in stencil apertures can cause dog-ears, insufficient solder, or bridging during subsequent printing, leading to open or short circuits on the SMT line and significantly impacting yield rates.
Q2:How to choose the right cleaning agent for an electric cleaning machine?
A2:We recommend using environmentally friendly water-based cleaning agents. These have high flash points and low odors. When used with the electric machine’s circulation filtration system, they ensure optimal cleaning results while reducing VOC emissions.
Q3: Is the DEZ-C750 cost-effective in terms of chemical consumption?
A3: Absolutely. The machine features a dual-tank design to keep cleaning and rinsing liquids separate. It also includes a direct liquid reflux system and uses compressed air to recover residual liquid after cleaning, which significantly reduces overall chemical consumption and operating costs.
