Ordering your PCB with a Specific Thickness
When you order a PCB’s you select a ‘Board thickness’ as below.
This is basically a label that our system uses to select the correct build-up for you your board.
The build-up is selected based on the Board thickness label, the number layers, type of material and copper thickness selected.
The actual calculated nominal ‘Total material thickness’ of the selected build-up is shown in the build-up window as below.
This is the total thickness of the base materials (laminate & prepreg) plus the selected copper thickness for that specific buildup.
This does not include the Copper Plating (Galvanic), Finial Finish Plating (Hal, ENIG etc.), Soldermask or Legend.
Our goal is to ensure that the thickness of the PCB is as close as possible to this selected value.
The thickness of a PCB must be measured on an area of laminate that is free of Soldermask, copper and legend.
Therefore, if you have defined your PCB to be 1.55mm thick then this is from the top laminate surface to the bottom laminate surface.
