Key
Flex Design Features included in EPD:
-
All entities and software features are optimized for flex design:
Teardrops, filleting, tapers, ground planes, cover layers,
routing, pushing, spreading, and more.
-
True arcs can be used in any entity in a design with accurate design
rule checking.
-
Automatic progressively increasing filleting of all trace bends that
use
built- in DRC to prevent radii from becoming too large.
-
Boundary nets can have unlimited complex shapes with optional arcs
and can be automatically generated from non-boundary artwork
from any source.
-
Teardrops have true arcs with variable radii and variable included
angles with optional individual editing.
-
Specialized Flex checking and CAM
tools, such as GapChk (checks internal and external gaps on
boundary polylines) and EtchCom (performs etch compensation on
any net, boundary or polyline with width) that are used by leading foundries.
-
Gerber output utility accurately converts all flex entities and
verifies a match to the original artwork with 100% confidence.

True Arc
capabilities for
o
Trace routing and
ground plane edges
o
Teardrops created
globally with DRC check
o
DRCs of all entities
o
Gerber file output
format
o
Tapered arcs.
·
Converts standard
straight tapers into flex compatible arced tapers
·
DRC and a detailed
layout versus schematic (LVS) checker performs full verification.
·
Can automatically
convert all overlapping non-boundary artwork into composite
boundary art (0 width closed polylines) with optional etch
compensation
·
Intelligizes, checks
and edits flex designs previously created in plain AutoCAD or from
Gerber files.
·
Automatic standard
cover layer creation, modification and custom cover layer openings
·
Complex boundary
nets with optional arcs
·
Automatic boundary
generation with inner and outer gap checking
·
Bus routing for
smooth flowing flex cables and parallel filleting of buses.
·
Highly efficient
manual and automatic routing with built in DRCs includes plowing,
pushing and automatic spreading of traces
·
Automatic Teardrop
creation using true arcs
with settable radius and included angle
leaves space for filleting of bends and has built in DRC.
·
Individual Teardrops
editing allows control of arc radius and included angle on each
teardrop.
·
Ground planes can
be cross hatched at any % copper or trace pitch to meet
flexibility requirements.
·
Ground plane pin
holes are automatically filled and islands smaller than a settable
threshold are automatically deleted.
·
Checks for plating
busses automatically.

·
Special flex
checking and CAM tools
·
Automatic flex
tapering (filleted tapers) and neck down tools
·
Dielectric bridges
are automatically created where desired.
·
Thick film printed
resistors are parametrically generated.
·
Customizable for
unique applications.
·
Flip chip and wire
bond die placement capabilities.
·
Complete schematic
utilities generate a parts list and a net list.
The GapChk command makes it
possible to work with complex 0 width closed polylines and check
self gaps within the same polyline. This checking command was
implemented for a major worldwide Flex foundry
Any image can be quickly
converted into clean close boundaries by using the following
commands.
Lclean – Automatically cleans us
messy line work by removing all unnessesary lines and arcs and
replacing overlapping lines / arcs with single lines /arcs.
AutoJoin – Converts the resulting
lines / arcs into closed 0 width polylines
DRC – The results of the above
can be automatically checked for clearances between nets and
GapChk may be used to check within a net.
The CoverLayer command
automatically generates the necessary openings in the cover layer
for soldering components to a flex circuit.
