Piezoelectric ceramics are functional ceramic materials that can convert mechanical and electrical energy into each other. Due to their positive and negative piezoelectric effects, dielectric properties, and elasticity, they are widely used in fields such as headphones, reverse radar, medical imaging, sound sensors, sound transducers, ultrasonic motors, etc.
The production process of piezoelectric ceramics is roughly similar to that of ordinary ceramics, with the production process being batching pretreatment pre firing granulation molding firing machining electrode polarization aging testing. Among them, the printing process involves printing silver electrodes on the surface of ceramics, with a thickness of about several micrometers to several tens of micrometers. After printing, drying and sintering are carried out to reduce the silver oxide in the silver paste to silver, which is then burned and infiltrated onto the ceramic surface to form a strong bonding layer.
At present, the printing of piezoelectric ceramics is mostly done using ordinary screen printing machines or manual printing methods, and the thickness of the film layer is difficult to accurately control. Moreover, with the continuous expansion of the piezoelectric ceramic industry and the increasing demand for products, mass production has become an urgent problem to be solved. Although there are also ordinary screen printing machines that can be used for mass production, the uniformity of film thickness is unstable, which seriously affects the yield of products.
Manual screen printing of piezoelectric ceramics
Thick film screen printing technology has been widely used in the piezoelectric ceramic industry, suitable for silver paste printing technology of circular piezoelectric ceramics, square piezoelectric ceramics, ring piezoelectric ceramics, and tubular piezoelectric ceramics. The high-precision thick film printing machine developed and produced by JYTUEC has been widely used in the thick film printing process of piezoelectric ceramics due to its high printing accuracy, uniform film thickness, and strong scalability.

With the rapid development of electronic circuits, piezoelectric ceramics are moving towards higher performance, smaller size, and more functions. JYUTEC has developed multiple models suitable for piezoelectric ceramics and can also modify fully automatic printing production lines according to large-scale production needs.
