Have you ever wondered how that almost invisible dust-proof glue on your phone screen is applied so precisely? Or how those tiny, intricate soldering points inside a chip are made quickly and steadily? The answer lies in a seemingly unremarkable small component—the piezoelectric valve. This little device is like the “invisible superhero” in the manufacturing industry, playing a huge role where you least expect it.
The working principle of a piezoelectric valve isn't overly complicated. Imagine gently pressing a balloon with your finger; the balloon deforms. A piezoelectric valve is like an incredibly sensitive “electronic finger.” When an electric current passes through a special piezoelectric material, the material instantly undergoes a tiny deformation. This deformation is almost invisible to the naked eye, yet it generates a powerful force capable of ejecting liquids or gases with extremely high precision. This magical ability to convert “electricity into mechanical motion” makes the piezoelectric valve a crucial player in the field of precision manufacturing.
In the semiconductor industry, the piezoelectric valve is a true “unsung hero.” Think of an integrated circuit as a super complex “city,” filled with thousands of “buildings” (transistors) and “roads” (circuits). In Wafer-Level Packaging (WLP), the piezoelectric valve needs to apply flux as precisely as an artist painting, carefully coating the chip pins that are just a few tenths the diameter of a human hair. Even the slightest deviation could disrupt the entire “city's” operation. In Flip Chip Chip-Scale Packaging (FCCSP), the chip underfill work done by the piezoelectric valve is like laying the foundation for a skyscraper—it uses glue to firmly bond the chip to the circuit board, ensuring stable performance in various extreme environments.
The piezoelectric valve also shines brightly in the consumer precision electronics field. Take the mobile phones we use every day as an example. In the manufacturing of Camera Module (CCM), the piezoelectric valve precisely applies dust-catching glue around the lens, like putting on a transparent “dust-proof mask” for the lens. It prevents dust from affecting photo quality without blocking even a sliver of light. In the screen display sector, during the MiniLED chip coating process, the piezoelectric valve faces an even more challenging task. It must apply special coating materials to each tiny LED chip with nanometer-level precision, making the screen colors more vivid and the contrast higher. It's like dressing each star in a custom “luminous outfit.”
So, why are more and more companies choosing piezoelectric valves? Besides their high precision, speed is another key factor. Traditional dispensing equipment is like a slow-moving carriage, while equipment driven by piezoelectric valves is like a high-speed sports car. In mass production, this speed advantage can save companies a significant amount of time and cost. Moreover, piezoelectric valves have a long service life and are relatively easy to maintain, much like a “hardworking and reliable employee” that can work stably for a long time.
