Is critical as it determines the performance of the board. High frequency circuit boards are typically made from materials such as PTFE, FR-4, and Rogers.Drilling is the process of creating holes in the board for components and connectors. High-frequency circuit boards require precise drilling to ensure the components’ proper placement and alignment. Plating is the process of adding a thin layer of metal to the board’s surface to create conductive pathways. Etching is the process of removing unwanted copper from the board’s surface to create the necessary circuit pattern.Assembly ProcessThe assembly process of high frequency circuit boards involves the placement and soldering of components onto the board. The process requires skilled technicians and specialized equipment to ensure the proper placement and alignment of components.The assembly process begins with the placement of surface mount components onto the board. The components are then soldered onto the board using a reflow oven or hand soldering. Through-hole components are then inserted into the board and soldered onto the board using wave soldering or hand soldering.Testing ProcessThe testing process of high frequency circuit boards is critical to ensure the board’s performance and reliability. The testing process involves several steps, including visual inspection, electrical testing, and environmental testing.Visual inspection involves checking the board’s physical appearance for any defects or damage. Electrical testing involves checking the board’s electrical properties, such as impedance and signal integrity. Environmental testing involves subjecting the board to various conditions, such as temperature and humidity, to ensure its reliability in different environments.In conclusion, the manufacturing of high frequency circuit boards involves several critical steps, including the PCB fabrication process, assembly process, and testing process.

As a professional PCB inspection method, visual inspection is crucial for troubleshooting PCB surface issues. It involves a range of techniques such as manual visual inspection, AOI, X-RAY, thermal imaging, ultrasonic, and more. Manual visual inspection (MVI) is a widely used method that relies on the trained technician’s ability to identify faults in the circuit board without the use of specialized equipment.The quality of manual inspection is highly dependent on the technician’s knowledge and experience. In this article, FS Technology will provide a comprehensive guide on manual visual inspection of PCBs, covering the necessary steps, tools, and techniques required for effective inspection. With our guide, you can perform accurate visual inspections and troubleshoot any issues with ease.Necessity of Manual InspectionPCBA manufacturing involves complex processes that require quality control to avoid faults. As the number of layers and component density increases, it becomes more challenging to guarantee quality. Therefore, incorporating various testing links in the manufacturing process has become crucial. Despite being a time-consuming, laborious, and inaccurate testing method, manual inspection is still necessary. For hobbyists, it is an easy-to-implement PCB testing method without limitation; for PCBA companies, it helps to avoid rework and speed up project progress; for customers, it adds a protective barrier without increasing costs.Let’s analyze the characteristics of this detection method:Simplicity: The inspection process does not require professional equipment support, and human eyes or magnifying glasses are enough to perform it.Penetration: Manual PCB inspection process is fast, and it can be added at any time during the entire production process.Randomness: It is not wise to rely on manual inspection for every board in batch orders. Typically, random sampling is used for inspection. If faults are found in the same batch of products, precise instruments like AOI, X-RAY, and others are necessary for detailed inspection.Fault tolerance rate: Manual inspection provides the information needed to eliminate faults present in the board when paired with other detection technologies.Guidance: Experienced experts execute manual inspection, and they can understand the design features of the circuit board clearly.Limitation: Cannot detect failures outside the line of sight, such as hidden solder joints.High error rate: It is difficult to check faults in complex circuit boards, and if the inspector is inexperienced, the process may become a mere formality.How to Manually DetectManual Visual PCB Inspection ChecklistMonitor the board thickness, surface roughness, and warpage throughout the PCB manufacturing process to ensure consistent quality.Inspect the conductive pattern for clarity, burrs, voids, and solder bridges to ensure the integrity of the signal path.Check for surface defects such as pits, scratches, pinholes, and dents that may affect the performance of the board.Verify the quality of pad plating, including firmness and brightness, to ensure reliable electrical connections.Inspect the clearance and integrityVisual Story Circuit 2025 - fotovj.com
