Our skilled team uses
hi-tech manufacturing equipment and advanced processes to build your circuit
board.
|
|
Our fabrication facility is optimized for small to medium production
runs, but we also place a special emphasis on servicing prototype business.
Our standard turnaround time on a bare board prototype order is typically
3-5 days.
CSI is qualified to fabricate MIL-PRF-55110 Type 2, double- and single-side
printed wiring boards. Our fabrication shop is qualified to Underwriters
Laboratories Inc. standard UL 796, Printed-Wiring Boards, and our flammability
classification under that standard is 94V-0.
We fabricate single-sided, double-sided, and multi-layer printed
wiring boards. Our fabrication processes are listed below:
-
a. Photo Dept.
-
We utilize 2 in-house photoplotters to expose photographic film under
computer controlled software. The photoplotter provides the precision necessary
for modern fine-line circuitry and our state-of-the-art CAM software assures
accurate set-up as well as fast turnaround. We maintain 24-hour email
notification to allow quick response to transfer of Gerber files for photo-plotting.
-
-
b. Drilling & Fabrication.
-
(1) Computer numerical control (CNC) drill, rout or score file generation
in which we generate a computer file from a CAD-produced Gerber file.
-
(2) CNC drilling
-
(3) CNC routing
-
(4) CNC scoring (very effective for assembly panelization)
-
c. Imaging.
-
Our imaging department uses the latest in dry film resist technology.
-
d. Screening.
-
Our shop is fully equipped to process nomenclature and solder mask operations.
-
e. Plating.
-
CSI has facilities and processes for plating Nickel, Gold, Copper and
Tin-Lead. Our processes are monitored routinely through lab analysis, X-ray
Fluorescence measurement, and panel cross-sections.
-
f. SMOBC.
-
We have on-site, the machinery and processes for fabricating Solder-Mask-Over-Bare-Copper
(SMOBC) PWBs using conventional or LPI solder mask.
-
g. Electrical Test.
-
We can test on-site your bare PWBs using our bed-of-nails, computer-driven
testing equipment.
-
PWBs tested with this equipment are 100 percent tested for open- and
short-circuit faults.
