We provide you complete
front-end engineering services for PCB manufacturing shops /
companies. Our technical knowledge of the PCB industry enables
us to provide professional and quality services and qualify your
design for manufacturing. Our CAM services include Inspection,
Complete CAM (1 ups, edits, panelisation, coupon placement,
drill programs, rout programs, drill cards). Customers also have
the option to request specific tasks like carrying out only 1
ups or edits, as per their specific needs.
LEAD TIME:
We handle all jobs on a one-day turn basis (overnight service
for our US based customers, upto 24 hrs for others), so you can
rest assured that the design will be in your server the next
morning (i.e the Gerber's are supplied to us at 6pm US specific
time and the PCB shop gets back the completed CAM files at 8am
US specific time the next day).
QUALITY CONTROL:
To ensure quality,
we run an exhaustive list of design rule check for every CAM
job.
For Example: We have a
separate QC engineer for Genesis and E-CAM who checks for errors
using a sophisticated QC tool. With our systematized and
timetested work flow process, the errors are brought down to a
bare minimum.
Listed below are the typical checks we do on every CAM job.
DESIGN RULE CHECK /
INSPECTION:
We run an exhaustive list of design rule checks for all boards
to avoid error that can possibly cause board scrap. All features
are thoroughly checked for violations before the board is
panelized. Some of the checks are :
1.Minimum air gap.
2.Minimum trace.
3. Open trace/Dangling traces
4. Power to ground short detection
5. Annular ring verification
6. Expose Trace.
7. Fab-to-Gerber mismatch.
EDITING:
A large number of DFM (Design for Manufacturing) actions has to
be performed on various layers, such as signal , solder mask,
silk screen layers to ensure productivity. Some edit & DFM
operations that we carry out are:
CLEAN UP:
1. Legend detection
2. Draws to flash
3. SMD attribute setting
4. Line unification
5. Redundant Line Removal
6. NFP Removal
7. Pad Registration
8. Sliver & Acute Angles
9.Exposed copper detection
OPTIMIZATION:
10. Signal layer optimization
11. Solder Mask Creation
12. Line Width Optimization
13. Silk Screen Overlap
14. Power & Ground Optimization
15. Teardrop Creation (snow man)
16. Copper Balancing
17. Etch Compensate
18.Netlist compare
PANELIZATION:
Panels are required in order to save setup time and provide
efficient usage of materials. So step & repeat of boards are
created on one large panel. Thieving bars and venting patterns
are added around the boards with Test coupons inserted in
specific locations. Also Mounting holes, optical targets (fiducials)
are added of various production machines. Text and logos are
added for easy identification of the board.
1.Complete Panelization Package
2.Customized venting pattern
3.Layer identification
4.Step and Repeat
5.Tooling targets
6.Compensation for lamination shrinkage
7.Generate customized coupons (testing, impedance, and
registration)
NC DRILL / ROUTING
PROGRAMMING:
NC files that are created for the Drill & Rout machines. The
following parts of the NC file are customized to the
requirements of each customer:
File header , Tool change
, Tool finish, Step & Repeat start , Step & Repeat end , End of
file
1. Any version/format.
2. NC drill program - first drill, second drill.
3. NC rout program.
4. Tool path generation.
5. Cover layer, Stiffner & Adhesive program.
6. Drill card creation.
