Entering FIDES Printed Circuit Boards
The following table describes the part parameters required for printed circuit boards (PCBs) when a FIDES model is selected for the calculation. This model supports the following subcategories of PCBs:
Blind Via
Micro-Via Technology
Pad On Via Technology
Via
Parameter
Type
Description
[Standard FIDES Parameters]
---
For more information, see FIDES Standard Part Parameters.
# of Layers
Integer
The number of layers in the PCB.
Type
Choice List [Parts Count and Families Count only]
The method by which the device is mounted. Choices are:
Surface Mount
Through Hole Mount
# of Mounting Points
Integer [Parts Count and Families Count also]
The number of mountings points for leads, which is the total of both surface-mounted and through-hole mounts.
Routing Class
Choice List
Required only by the FIDES 2004 model.
The way in which the board electrically connects components using conductive pathways. Choices are Class 1 through Class 6.
Min Conductor Width / Spacing
Choice List (μm)
Required only by the FIDES 2009 model.
The minimum spacing between conductors or pads. Many choices are available. Consider the zone, or for a multi-layer PCB, consider the layer, with the highest density.
