Why Do We Need Conductive Silver Paste Defoaming Machine

Photovoltaic & Printed Electronics

Silver paste is screen printed for photovoltaic busbars, touch screens and RFID antennas. Air trapped during stirring causes broken lines, pinholes and circuit defects and damages the integrity of conductive paths.

Electrical Performance Consistency

Silver powder agglomeration and bubbles result in uneven printed film thickness and fluctuating sheet resistance, leading to unstable device resistance across batches and lower yield.

High-value Paste

Silver paste comes with high material cost. Poor defoaming causes printing rejects and increases material expenses. Stable and reproducible defoaming process is required.

✨ Traditional Dilemma: Manual stirring brings air entrapment and silver powder agglomeration, leading to unstable sheet resistance and intermittent circuit conduction of printed lines. Synchronous vacuum defoaming and dispersion is required.

Why Choose SIENOX Silver Paste Defoaming Solution

Integrated Defoaming & Dispersion

Vacuum stirring realizes defoaming and silver powder deagglomeration at the same time, producing dense circuits and better printability.

Non-contact & Clean

No impeller contact. No contamination to silver paste and unchanged formula, delivering consistent sheet resistance and conductive performance batch by batch.

Protect High-value Paste

Stable defoaming cuts printing rejects and reduces waste of high-cost silver paste with reproducible formulations.

  • How does the stirring and defoaming machine work?

    The SIENOX stirring and defoaming machine performs defoaming through centrifugal force at revolution and stirring through shear force formed by revolution and rotation,

    Assisted by a vacuum pump to extract gas and achieve a vacuum state, removing nanoscale tiny bubbles. No contact with materials, no secondary pollution, and no secondary waste.

  • What is the function of a defoaming machine?

    A defoaming machine is a device used to remove bubbles from liquids. Its function is to assist in the liquid mixing, reaction, coating, printing, infusion and other process steps in the production process, avoiding the generation of bubbles and their impact on the final product. In many industrial and laboratory environments, removing bubbles is essential as they may have a negative impact on product quality, such as affecting surface tension and stability. Defoaming machines typically use various techniques such as vibration, ultrasound, centrifugation, etc. to achieve effective bubble removal. It has a wide range of applications, including but not limited to semiconductors, solar energy, optics, biotechnology, materials science, etc.

Precautions for Use

NotesOperation Instructions
Loading & Rotation SpeedMatch loading volume and rotation speed for high-solid silver paste to prevent silver powder sedimentation and uneven dispersion.
Anti-oxidation & Anti-contaminationAvoid silver powder oxidation and cross-contamination; keep tools and containers clean.
Slow Pressure ReliefRelease pressure slowly after defoaming to prevent paste re-foaming and splashing.
Prompt PrintingPrint immediately after defoaming and dispersion to avoid silver powder agglomeration and sedimentation during standing.
