PCB (Printed Circuit Board) equipment

1. Precise Control of Chemical Agents
In PCB production, chemical agents are used for surface treatment, etching, and cleaning. YNTO thermoplastic plastic pneumatic diaphragm valves precisely control the flow and pressure of these chemicals. Made from chemically resistant thermoplastic materials, these valves can handle strong acids, alkalis, and other corrosive chemicals. The pneumatic drive system provides high-precision flow adjustment, ensuring uniform distribution of the chemicals and avoiding process fluctuations or product defects due to uneven chemical concentrations.

2. Application in Etching Processes
In the etching process, YNTO pneumatic diaphragm valves control the flow of etching solution. Designed to operate reliably in highly corrosive environments, these valves provide precise flow regulation, ensuring even distribution and stable flow of the etching solution within the etching tank. This precise control is essential to prevent uneven etching, reduce material loss, and ensure process efficiency and consistency.

3. Application in Cleaning Processes
The cleaning process removes residual chemicals and contaminants from the PCB surface. YNTO pneumatic diaphragm valves regulate the flow and pressure of cleaning solutions in the cleaning system. Their corrosion resistance and high-precision pneumatic control ensure uniform spraying and effective cleaning of the solution, maintaining efficiency and consistency even under high-temperature and high-pressure conditions.

4. Application in Stripping Processes
During the stripping process, YNTO pneumatic diaphragm valves control the flow and pressure of stripping agents. Their corrosion-resistant materials and precise flow control ensure the even distribution of stripping agents, avoiding overuse or underuse of the stripping solution. This high corrosion resistance and stability guarantee efficient stripping and complete removal of the film layer.

5. Performance in High-Temperature and High-Pressure Environments
Certain PCB manufacturing processes involve high-temperature and high-pressure conditions. YNTO stainless steel high-temperature control valves are designed to withstand these extreme conditions. With high-temperature materials and pneumatic drive systems, these valves ensure stable operation under high-temperature and high-pressure environments. Their excellent corrosion resistance and high-temperature performance ensure reliable and precise control in demanding process conditions.

Summary
YNTO thermoplastic plastic pneumatic diaphragm valves are essential in PCB manufacturing, offering outstanding corrosion resistance, precise flow and pressure control, and stable performance in high-temperature and high-pressure environments. These valves provide critical support for chemical control, etching, cleaning, and stripping processes. Their technical advantages enhance production efficiency, ensure process stability, and maintain product quality, delivering robust technical support for the manufacturing process.
