The stackup design process typically begins with the electrical requirements of the PCB. The designer will need to determine the number of layers needed, the type of materials to use for each layer, and the thickness of each layer. The designer will also need to consider the mechanical require...

Another desirable objective, from a mechanical point of view, is to have the cross section of the board symmetrical (or balanced) in order to prevent warping. For example, on an eight-layer board if layer two is a plane, then layer seven should also be a plane. Therefore, all the confi...
Below is an example of HDI stack-up generated using the Stackup Designer. 8-layer HDI stack-up generated using Stackup DesignerXi Main features of this Stackup Designer tool: Consists of a stack-up library which includes single and sequential lamination build-ups Linked to 2D field solver-...

双面板是一种两面都有敷铜、都可以布线的PCB。它包括顶层(Top Layer)和底层(Bottom Layer)两个层面,两层面间通过焊盘或过孔(Via)相连接,完成两层间的电气连接。双面板的面积比单面板大了一倍,而且布线可以互相交错(可以绕到另一面),因此,双面板适用于较复杂电路。
The board fabricator takes the lay-up of a particular product and determines the relationship of the number of core laminates vs. prepreg vs. total construction. As an example, a typical cross-section might be something that looks like the following figure: Layer Stack-up – Ten Layer ...
1.3.2 Six Layer Stack-Up Figure 1.3.2 Six Layer PCB Stack-Up Example In this example, the reference planes for the high speed signals on the top layer are the power planes on layer 2. Stitching capacitors from the associated reference power plane to ground are therefore required. The signa...
For example, on an eight-layer board if layer two is a plane, then layer seven should also be a plane. Therefore, all the configurations presented here use symmetrical, or balanced, construction. If a non-symmetrical, or unbalanced, construction is allowed additional stack-up configurations are...
Layer Stackup As noted before in the beginning of this article, the printed circuit boards can be made of several layers. When a PCB is designed with the aid of an EDA software, often are specified several layers that doesn't necessary correspond to conductive material ( copper ). For exa...
