Hybrid PCB

Hi Manager,

Lower dielectric constant and lower dielectric loss material are used for PCB can meet the requirement of high frequency high speed signal transmission. In order to get the same performance with competitive advantages, FR-4 is introduced in the multilayer high frequency PCB.

Benefits

a) SI performance improvement over the stack-ups with all FR4 board;

b) Cost reduction over stack-ups with all low loss material.

c) Reduce signal loss at high frequencies as well

RO4003C+FR4 (example)

  |  ---          ---------- Layer 1 (Top layer) 0.018mm+plating   

  |                          Dielectric RO4003C 0.203mm

  |               ---------- Layer 2 (mid. layer 1) 0.035mm

1.1 mm +/-10%     Core FR-4 0.5mm

  |               ---------- Layer 3 (mid. layer 2) 0.035mm

  |                          Dielectric FR-4 0.200mm

  |  ---          ---------- Layer 4 (Bottom layer) 0.018mm+plating
