Steel Mesh Ultrasonic Cleaning Machine in SMT Industry

1. Introduction to Steel Mesh Ultrasonic Cleaning Machine

The steel mesh ultrasonic cleaning machine is a device specifically designed for cleaning SMT (Surface Mount Technology) steel meshes (also known as templates or Stencil). It utilizes the cavitation effect of ultrasonic waves to remove solder paste, flux residues, and other contaminants within the mesh holes. It is widely used in fields such as electronic manufacturing, PCB (Printed Circuit Board) assembly, and semiconductor packaging, ensuring the high precision and long-term availability of steel mesh.

2. The Importance of steel mesh cleaning

SMT steel mesh is used for printing solder paste on PCBS. If the mesh holes are clogged, it will lead to:

Uneven solder paste printing → affects the quality of soldering

Component offset or false soldering → increases the defect rate

Shortened service life of steel mesh → increased production costs

Traditional manual wiping or chemical soaking is difficult to thoroughly clean the micron-sized mesh, while ultrasonic cleaning can efficiently solve this problem.

3. The working principle of the steel mesh ultrasonic cleaning machine

Ultrasonic cavitation effect: High-frequency ultrasonic waves (typically 40kHz - 80kHz) generate tiny bubbles in the cleaning solution. When they burst, they produce an impact force to remove residues from the steel mesh holes.

Cleaning solution assistance: Specialized water-based or solvent-based cleaning agents enhance the decontamination effect.

Spray or rinse (optional) : Some models are equipped with a spray system to enhance cleaning efficiency.

Drying system: Hot air or vacuum drying to prevent water stains from remaining.

4. Application scenarios of ultrasonic cleaning machines for steel mesh

(1) SMT electronic manufacturing

PCB solder paste printing steel mesh: Remove solder paste and flux residues.

Semiconductor packaging steel mesh: Clean high-precision micro-holes (<50μm).

(2) Flexible circuit board (FPC) production

Cleaning of polyimide (PI) steel mesh to avoid mechanical damage.

(3) High-precision metal mask cleaning

Decontamination of OLED and Mini LED evaporation masks.

(4) Cleaning of other precision screen plates

Screen printing plates, 3D printing templates, etc.
