Layer Stack 4 Layers PCB.
Options of thickness of copper in layers, PCB 1,6mm:

  1. copper thickness inner and out layers
    out layers 1 oz
    inner layers 0,5 oz
    Core thickness ?
    Prepreg thickness?
  2. copper thickness inner and out layers
    out layers 1 oz
    inner layers 1 oz
    Core thickness ?
    Prepreg thickness?
  3. copper thickness inner and out layers
    out layers 0,5 oz
    inner layers 1 oz
    Core thickness ?
    Prepreg thickness?

What option standard?
how much is option No. 2
It is possible in more detail on a stack of layers for PCB 1,6мм

#2

inner layers type Power planes.
Internally supply layers, inverse. By production it is considered? Where it is possible to specify that inside layers layers inverse, obviously?

#3

hi there,

What option standard?
NO.1

how much is option No. 2?
sorry, we don’t offer this kind of PCB now.

It is possible in more detail on a stack of layers for PCB 1,6мм?
which hand of detail do you want to realise? we will as far as possible to meet you.

Thanks.
Look, please, a drawing. Thickness of the core material for PCB 1,6mm?
The inner layer (Power Plane) can be inverse? When, out layers not the inverse.

hi there，
sorry for the later reply.

  1. the core 0.4-1.2mm depends your pcb thickness, for example: the pcb thickness is 1.6mm, the core is 1.6-0.2-0.2=1.2mm.
  2. yes, we can accept the inner layers are Negative.
