In high-frequency PCB design, a Break-away hole is a specialized hole that ensures signal integrity. It enables effective connections on multilayer boards and allows for easy disconnection during assembly, enhancing flexibility and maintainability. By optimizing the size and position of these holes, designers can minimize signal loss and improve performance, making them crucial for high-frequency applications. |

In high-frequency PCB design, selecting the right PTH (Plated Through Hole) and NPTH (Non-Plated Through Hole) is crucial for ensuring signal integrity. PTH refers to holes that pass through the circuit board to connect circuits between different layers, while NPTH refers to holes that do not go through the entire board, typically used for mechanical support or routing. |

Lead-Free Hot Air Solder Leveling（ LF-HASL）is widely used in high-frequency PCBs. It uses lead-free tin alloys (e.g., Sn-3.0Ag-0.5Cu) instead of traditional tin-lead ones. The process involves pretreating the PCB welding surface by chemical cleaning and other methods, placing it in equipment, melting the alloy, and spraying with high-pressure gas to form a uniform tin layer. |
