Hybrid PCB | Mixed Material 4-layer PCB
Made On 20 mil RO4350B + FR4 With Blind Via
(Printed
circuit boards are custom-made products, the picture and parameters shown are
just for reference)
Layer
1 to layer 2 is the core of 20mil (0.508mm) RO4350B high frequency material,
the signal transmission lines are on first layer copper, then layer 3 to layer
4 is another core of epoxy glass material. The 2 cores are bonded by a sheet of
adhesive (prepreg).
Basic specifications：
Layer
count: 4 layers
Panel:
75mm x 82mm = 1 type = 1 piece
Surface
finish: Immersion gold
Copper
weight: Outer layer 70 um/ Inner layer 35 um
Solder
mask / Legend: green / white
Final
PCB height: 1.6 mm
Standard:
IPC 6012 Class 2
Packing:
20 panels are packed for shipment.
Lead
time: 10 working days
Shelf
life: 6 months
Features and benefits：
1) The
temperature coefficient of dielectric constant is among the lowest of any
circuit board material, making it ideal for temperature sensitive applications;
2) RO4350B
exhibits a stable dielectric constant over a broad frequency range. This makes
it an ideal substrate for broadband applications;
3) Signal
integrity performance improvement over the stack-ups with all FR4 board;
4) ISO9001,
ISO14001, IATF16949, UL Certified factory
5) Prototype
to mass production capability;
Applications：
Mixer,
Radar data acquisition converter, Spread spectrum, Duplexer
