Technology Resource Center: Lamination lay-up

Every manufacturer has a preferred method of constructing printed circuit boards in their facility. There are many options for the fabricator depending on the prepreg glass styles being used. Furthermore, the stack detail of the board will affect how the prepreg will react during the lamination cycle. Prepreg between two plane layers will result in a thicker overall package than prepreg placed between two signal layers.

The following examples are provided as guidelines for creating lamination stack-ups using a foil construction. They are based on Westak's preferred lamination methods. Cores and/or prepregs may be substituted at the manufacturers discretion.

Glossary

Pressed Thickness - Total thickness of all base copper and core material / prepreg thickness.
Finished Thickness - Total thickness calculated after electrolytic copper plating.
P/P - Plane to Plane
S/P - Signal to Plane

S/S - Signal to Signal
