  • Stack-up Design: It can be cost-effectively optimized by hybrid stacking with FR4 material. Attention should be paid to the CTE differences between different substrates during stacking to prevent warping caused by thermal stress.
• Material Cutting:
  • Use laser cutting or high-precision mechanical cutting equipment to ensure smooth cut edges. The material’s flexibility requires precise cutting techniques to minimize damage during the cutting process.
• Drilling and Plating:
  • During drilling, lower drill speeds should be used to avoid overheating. For through-hole plating, smooth hole walls are required to ensure conductivity and mechanical strength meet standards.
• Lamination and Pressing:
  • Lamination should employ low-temperature pressing technology. It is recommended that the pressing temperature not exceed 288°C to prevent material delamination or performance degradation under high temperature.
• Surface Finish:
  • Common surface finish methods include Electroless Nickel Immersion Gold (ENIG), Immersion Tin, and Organic Solderability Preservative (OSP). These methods ensure good solderability and stability of the PCB surface without affecting the material’s electrical performance.
• Testing and Quality Control:
  • After production, the PCB needs to undergo high-frequency network analysis to verify key parameters such as dielectric constant, dissipation factor, and impedance consistency. Thermal cycling tests and temperature resistance tests are conducted to ensure product reliability under extreme environmental conditions.

IV. Usage and Storage Precautions for Rogers 5880B PCB

• Storage Conditions:
  • Rogers 5880B material should be stored in a dry, low-temperature environment, avoiding high humidity and high temperature conditions to prevent moisture absorption that could affect electrical performance. Sealed packaging is recommended to keep the material dry.
• Precautions During Processing:
  • Avoid strong bending or stretching of the material during processing to prevent damage to the substrate structure.
• Requirements for High-Precision Applications:
  • For high-precision applications, it is recommended to perform manufacturing and assembly in a dust-free environment to ensure the quality and stable performance of the finished product.
