Designed for use in high density multi-layer boards, FR4 is suitable for surface mount, MCM-Ls, direct chip attach, automotive and wireless communications. The characteristics of FR4 also make it particularly beneficial in high volume fine line multilayers and PCMCIA applications.

The predictability and consistency of this material provides for tremendous ease of processing at the circuit board fabrication site, and its electrical and mechanical characteristics make it user friendly for both designers and fabricators of critical circuits.

Flex and Rigid-Flex

Flex and Rigid-flex circuit boards have become increasing popular due to their unique applications. Flex and Rigid-Flex circuit boards can do what regular standard rigid circuit boards can not do. They can fold, twist, and wrap around tight/small packaging areas.

Most flex circuit boards are being manufactured using “Kapton”, a material developed by Dupont Corporation. This polyimide film based material is resistant to heat, has dimensional stability and a low dielectric constant of 3.6. There are three variants of the Kapton material:

  1. Pyralux LF (Acrylic Base Adhesive-not Flame Retardant)
  2. Pyralux FR (Acrylic Base Adhesive-Flame Retardant)
  3. Pyralux AP (Adhesiveless-for more demanding high-performance applications)

RF/Microwave/High Speed

As microprocessor speeds continue to escalate and wireless communications proliferate, the need for a fast and cost effective solution becomes paramount. Power Design Services has over 10 years of experience working with different type of laminates.

Getek

  • Loss tangent = .012 (slightly high) (usage in analog circuits up to 1.2 ghz and up to 2.0 ghz in digital applications) (Stability in temperature variations good)
  • Er = 3.5 to 4.3 (at 1.0 mhz) (specific Er is dependent on glass-resin- ration – Er is virtually constant form 1.0 mhz to 2.0 ghz)
  • CTEr = +220ppm per degree C (high). Tg is 180 degrees C.
  • Electro-deposited Copper only. (helps in peel strength and delamination but somewhat limits etch width tolerance due to undercutting).

Hybrids

Hybrid circuit boards are a way of reducing cost. It is a process of combining standard FR4 laminate with other RF/microwave/high speed laminate. The technology gives engineers the ability of controlling the design on desired layer(s) yet still reducing cost with standard FR4 on the remaining portion of the circuit board.
