Ultrasonic Spray Coating of Photoresist for Panel Level Packaging Panel-level packaging has emerged as a core advanced packaging technology in the semiconductor industry, featuring high integration, high production efficiency and low unit cost, and is widely applied in high-end chip manufacturing. Unlike traditional single-package packaging processes, panel-level packaging production needs to complete photoresist coating operations on ultra-large-area substrates, which integrate hundreds to thousands of independent packaging units. The [...]

Development Trends of Miniaturized Wrist Surgical Instruments Wrist-Mounted Surgical Instruments: Multiple Technological Barriers and Development Directions at the Distal End of the Surgical Robot In the overall system architecture of a surgical robot, the control console outputs operational commands, the robotic arm provides spatial displacement support, the vision system performs intraoperative scene imaging, and the wrist-mounted instrument is the end-effector that directly enters the body cavity to perform [...]

Ultrasonic Spray Coating for SU-8 Photoresist Ultrasonic Spray Coating for SU-8 Photoresist: An Innovative Solution Breaking Through Traditional Coating Bottlenecks SU-8 photoresist is a negative near-ultraviolet photoresist based on an epoxy resin system. Its molecular structure contains eight epoxy groups, which undergo a cross-linking reaction under ultraviolet irradiation to form a stable network structure. With its extremely low light absorption in the near-ultraviolet 365–400 nm wavelength range, excellent [...]

Superhydrophobic Coating Technology for Camera Lenses Ultrasonic Coating Technology: Empowering Superhydrophobic Protection Upgrades for Surveillance Camera Lenses In fields such as security surveillance, traffic control, and environmental monitoring, surveillance cameras serve as critical visual acquisition devices, and their imaging quality directly determines the accuracy and reliability of data collection. As the core optical component of a camera, the lens is often exposed to harsh outdoor environments for extended [...]
