transfers the layout data to Mechanical Following formats are supported:
– Ansoft ANF – Cadence BRD/MCM/SIP – ODB++ TGZ – ICEPAK BOOL+INFO – ICEPAK COND+INFO
SpaceClaim now has the ability to import ECAD files. Can import:
– Layout Geometry – Layer Topology
Supported File Formats:
– Cadence SPB (*.brd;*.mcm;*.sip) – ANSYS Electronics Database (*.def) – Other ECAD (*.tgz;*.xml;*.cvg;*.gds;*.sf;*.strm)
Traditional approach does not work
Galileo Board
What is Trace Mapping?
Trace mapping provides a fast and efficient method to model such PCBs without incurring the inordinate cost of processing geometry and mesh.
• ~30 mins • Import into Design Modeler / Space Claim
• ~10 mins • Perform Boolean operation and share
topology • 24hrs and still running
• Import Geometry into Mechanical • Mesh • Specify boundary conditions • Solve
• The exported bodies are overlapping. • Import into Design Modeler / Space Claim • Perform Boolean operation and share
topology • Import Geometry into Mechanical • Mesh • Specify boundary conditions • Solve
Trace Mapping
Simplified Geometry and Mesh
Layout
Metal map on Target Mesh
Layout representation as Metal Map
Creating Simplified Geometry
ECAD Import in Space Claim
– Geometry is modeled by just the dielectric layers. • Very simple geometry which can be easily generated and meshed.
– Effect of traces is modeled by checking for the presence of Metal Trace in each element, and assigning a new material with material properties calculated based on Metal fraction.
ECAD Import in Space Claim
ECAD Files can be imported into SpaceClaim using File -> Open
11 layers Each layer as a separate body Shared Topology
Details show Material Assignment for each layer
– It automatically adds an Imported Trace object under the Imported Trace folder
Importing Trace Data in Mechanical
The PCB 3D layout files can be specified in the External Data Transfer link from External Data Setup to Model cell in M来自百度文库chanical system
Galileo Board
Analyzing Printed Circuit Boards (PCBs) and Packages
3456 Bodies
How to prepare the board for analysis?
Traditional Approach • Export step file from the board layout.

How to prepare the board for analysis?
Traditional Approach • Export step file from the board layout.
For each file user can specify:
– Rigid transforms to align the board outline with geometry.
Importing Trace Data in Mechanical (contd.)
The refresh operation on Model cell automatically inserts Imported Trace folder in the Tree.
