Inner-layer browning process for PCB
YNTO UPVC electric switch valves and YNTO UPVC electric control valves exhibit exceptional performance in the inner-layer browning process of printed circuit boards (PCBs). Here is a detailed technical description:

1. Application Background
In the PCB manufacturing process, the inner-layer browning is a critical step used to enhance copper layer adhesion and ensure circuit reliability. This process involves the use of chemical agents under high temperature and pressure conditions. YNTO UPVC electric switch valves and electric control valves play a crucial role in precisely controlling the fluid flow and distribution of chemical agents, ensuring the stability and consistency of the browning process.

2. Performance of YNTO UPVC Electric Switch Valves
YNTO UPVC electric switch valves are used to control the opening and closing of chemical agents in the browning line. Made from corrosion-resistant UPVC materials, these valves withstand the corrosive nature of chemical agents, ensuring long-term stable operation. In switching control, YNTO electric switch valves offer rapid response and high reliability, accurately toggling fluid pathways and preventing issues such as chemical leakage or unstable flow, thus enhancing the overall efficiency and safety of the browning process.

3. Performance of YNTO UPVC Electric Control Valves
YNTO UPVC electric control valves are used for precise regulation of chemical agent flow and pressure in the browning process. Their precise adjustment capabilities ensure uniform distribution and stable flow of chemicals, achieving fine control over the process. These control valves function reliably in high-temperature and corrosive environments, supporting efficient and repeatable process operations. Their high-precision regulation optimizes chemical usage, improves PCB processing quality, and reduces production costs.

4. Technical Advantages
Strong Corrosion Resistance: YNTO UPVC electric valves, made from UPVC, offer excellent corrosion resistance, providing long-term stability in the corrosive environment of the browning process.
Precise Control: The precise control functions of both switch and control valves ensure accurate flow and pressure regulation throughout the process, guaranteeing precise chemical distribution.
High Reliability: The valves' rapid response capabilities enable immediate adjustments or switching of fluid paths, reducing process fluctuations caused by inadequate control.
High-Temperature Durability: Designed to handle high-temperature conditions, the valves operate stably in the browning process, ensuring normal system operation.
5. Summary
YNTO UPVC electric switch valves and electric control valves demonstrate exceptional performance in the inner-layer browning process of PCBs by providing stable and precise control, significantly improving process efficiency and product quality. Their corrosion resistance, high-precision control, and reliability make them ideal choices for the browning line, offering reliable technical support for PCB production.
