Precision cleaning process of PCBA Precision cleaning process of PCBA - Semiconductor Coating - Cheersonic The COVID-19 pandemic has raised the importance of wearable medical devices and remote monitoring and diagnostic equipment to unprecedented heights. But these devices, as well as complex PCBAs (printed circuit board assemblies), must provide reliable and consistent performance, especially when they are used in life-sustaining equipment. Cleaning is a key factor in maintaining [...]

Ultrasonic Photoresist Coater Ultrasonic Photoresist Coater - Spraying Photoresist For MEMS Wafers The ultrasonic spray coating machine UAM6000 combines new spray and control technology to achieve more uniform, denser and controllable thin film coating. The equipment integrates multiple systems, such as ultrasonic, carrier gas, heating plate, vacuum adsorption and exhaust gas discharge. At the same time, it can be applied to a full range of ultrasonic nozzles, suitable [...]

Photoresist Spraying UAM6000 ultrasonic photoresist spraying equipment can spray photoresist thickness from 2um to 35um on substrates with diameters from 65mm to 200m. According to our experience with photoresist spraying, its solvent is generally Acetone, MEK, PGMEA or butyl acetate. Firstly the substrate must be level, non-levelness will cause unevenness in the film. Then for the uniform and controllable coating thickness, it requires higher coating process. Our company [...]

Challenges in Medical PCB Board Design Challenges in Medical PCB Board Design - Cheersonic Ultrasonic Nozzle Knowing how to build printed circuit boards for medical applications and robotics is just the beginning. Each application or robot requires a separate design, which may encounter the following difficulties: • Quality: Medical grade PCB boards have higher standards that cannot be compromised and need to comply with the ISO 13485 standard. [...]

Medical Grade PCB Board Protection Medical Grade PCB Board Protection - Ultrasonic Spray Deposition - Cheersonic There are many things to consider when developing a PCB board to design specifications, especially physical protection and corrosion resistance. For example, the assembly process must be well planned to provide through-hole device mounting, placement or surface mount options for embedded and soldered devices. Finished products are often used in medical imaging [...]

Changes In Chip Design Rules Chip design rules are quietly changing! For years, manufacturers of mobile processors have focused on optimizing designs for maximum performance within limited power budgets, storage space, and bandwidth. In the past, clearly these considerations have not been taken seriously in markets such as the data center or personal computer (PC). Today, a revolution in the traditional data center and PC markets is underway—changing [...]

The difference between hard mirrors and soft mirrors Endoscopes can be divided into rigid and flexible endoscopes. 01 Differences in application fields Generally speaking, the cavity is more suitable for rigid scope, and the tube is more suitable for soft scope. Rigid endoscopes mainly enter sterile human tissues and organs or enter sterile chambers of the human body through surgical incisions, such as laparoscopy, thoracoscopy, arthroscopy, intervertebral discoscopy, [...]
