Standard layer buildup

You can choose between three options for your multilayer buildup:

  • Variable layer buildup (Standard)Changing stackup according to availability
  • Defined layer buildupMulti-CB’s fixed stackup
  • Custom layer buildupStackup according to your specifications

The differences are explained in the following.

Variable layer buildup (Standard)

As a standard, you get a variable layer buildup, which is defined by following parameters. The typical values are added:

  • Material type [FR4]
  • Final thickness [1,55mm]
  • Cu outer layers (final) [35µm]
  • Cu inner layers (final) [35µm]

The used prepregs and cores can vary. Due to this flexibility in production, you benefit from shortest production times.

The variable layer buildup is the most common option selected by our customers. The variable layer buildup can be utilized in most applications.

Defined layer buildup

For certain applications it is necessary that the isolation thicknesses between the layers are defined, e.g. for impedances. For this, Multi-CB offers the following fixed defined layer buildups, which you can choose in the online calculator.

The defined layer buildup comes without surcharge.

4 layers: 4L-01 (1.6mm)

4 layer PCB defined buildup

Layer buildup, through thin outer layers, optimized for:

  • Better signal integrity
  • Space savings through narrower tracks for impedance control
  • Easy realization of 0.2mm blind vias (aspect ratio)

* Prepreg thicknesses after pressing, at approx. 80% copper utilization on the inner layers.

6 & 8 layers preparation.

The defined layer buildup does not include impedance control! An impedance control implies additional charges and can only be ordered with a custom layer buildup.

Custom layer buildup

The custom layer buildup is special production.

Make your choice from the of common cores and prepregs. Please clarify the material availability with our technical department.

The custom layer buildup does not contain impedance control. If you need impedance control, please select it in the online calculator and provide us with your impedance requirements.
