Application of PCB Laminate

While selecting the appropriate laminate material, keep the following things in mind:

  • Electrical Parameters: Identify the circuit’s electrical needs, such as the frequency spectrum, transmission frequency, and voltage control capabilities. Always choose laminate material with the necessary electrical characteristics, including the dielectric constant, loss tangent, and susceptibility.
  • Thermal Specifications: Analyze the circuit’s thermal needs, including the operating temperature range and heat capacity. A composite material that satisfies the necessary thermal qualities, such as TG, CTE, and thermal stability, should be used.
  • Mechanical Requirements: Consider the circuit’s structural needs, such as the degree of compressive stresses, dimensional stability, and stiffness. Always choose a composite material that satisfies the necessary mechanical requirements for tensile strength, flexural strength, and elastic modulus.
  • Environmental Parameters: Find out what the circuit’s ecological needs are, including how much humidity, toxins, and UV radiation it will be exposed to. Choose one laminate material with the necessary environmental qualities, such as chemical resistance, water absorption, and UV durability.
  • Expense: Evaluate the laminate material’s price and if it fits into the project’s finances.
  • Availability: Evaluate the laminate’s accessibility and if it can be obtained in the necessary quantities and with the required lead times.

By taking these things into account, one may choose the proper laminate material that satisfies the demands of the circuit design and guarantees the PCB’s good performance and dependability.
