Assessing the Quality of FPC Circuit Boards
With the continuous progress of science and technology, the utilization of FPC circuit boards has expanded across various industries due to their intelligence integration.
Identifying Good and Bad Circuit Boards by Appearance
- Size and Thickness Standards: FPC circuit boards have unique thickness specifications that differ from standard boards. Customers should verify these measurements for quality assurance.
- Light and Color: Proper insulation is indicated by a bright and well-covered ink layer on the external circuit board. Dullness or inadequate ink coverage may signify poor insulation quality.
- Soldering Appearance: Quality soldering is crucial for component stability. Careful inspection of solder joints is necessary to prevent detachment and ensure overall soldering quality.
Requirements for High-Quality FPC Circuit Boards
- Post-Installation Usability: Electrical connections should meet usability standards after installation.
- Compliance with Specifications: Line width, thickness, and spacing must adhere to specifications to prevent overheating, breakage, or short circuits.
- Temperature Resistance: Copper layers should withstand high temperatures without peeling.
- Oxidation Resistance: Copper surfaces must resist oxidation to maintain efficiency and prevent rapid deterioration.
- Electromagnetic Radiation: Avoid unnecessary electromagnetic radiation.
- Mechanical Integrity: Shape preservation is crucial to prevent housing deformation and misalignment of screw holes during installation.
- Environmental Considerations: High-temperature, humidity, and special resistance factors should be taken into account.
- Surface Mechanical Properties: Surface properties must align with installation requirements.
When selecting FPC circuit boards, it is essential to consider these factors to ensure quality and performance meet industry standards.
