Drawings: |

We
can generate schematic drawings from engineering
hand sketches, spec sheets and schematic
CAD package, then generate a netlist and
BOM and email to you for checking. If you
don't have a schematic CAD package and we
design your schematics, we will give you
a net list, BOM and Adobe Acrobat .PDF files
of the schematic for you to view on your
own PC, print and check. We will need your
engineering approval of the schematic and
netlist before the PCB design process begins. |

Change Order (ECO): |

AutoECO
enables you to forward annotate a printed
circuit board from Capture to Layout. AutoECO
also resolves "pin-to-pin" conflicts
that may arise due to pins that are missing
from a chosen footprint, or pins that are
named differently in the Capture than they
are in Layout. (For example, a diode may
have pins named pin A and pin C in Capture,
but named pin 1 and pin 2 in Layout.)
AutoECO selectively communicates information
from Capture to Layout, or from one printed
circuit board to another. In other words,
when bringing data into Layout from Capture,
you can choose the appropriate AutoECO option
to annotate only the data that has changed. |

All
the current surface mount technology (SMT)
design and fabrication techniques available
today can be utilized. Data line is heavily
experienced in ultra hi-density single and
double-sided component placement optimization
of very fine to ultra fine pin pitched parts,
complex manual routing and auto-routing
techniques. Mother-daughter board stacking
utilizing both rigid and flex circuit interconnection.
Fine-line traces/spaces, mini-vias, Embedded
vias, shielded fast clock routes, fixed
matched pairs, complex analog/digital multi-split
VCC/GND planes, .040 dia, .100 spaced IC
test point placement.
From netlist we pre-set the layout design
rules before routing or placement of components
begin. Design Rules Checking ( DRC) continually
checks for both continuity and artwork opens
and shorts. We can create complex, custom
board outlines with many curves, slots,
cut outs and angles, height restrictions,
route/component keep-outs, tooling and board
outline, etc. Meticulous attention is given
to all aspects of the design, including
the silkscreen, solder mask and solder paste
stencil. To simplify locating components
during prototype de-bugging, we can re-sequence
the component labels on the silkscreen.
We have the facility to Design Single Layer,
Double Layer, Multi Layer and Surface Mount
Technology. |
| Library
Development: |
|
Our Engineers
are creating schematic and Footprint library
as and when the new component is available
in the industry.
We can create
schematic symbols for your organization
on a regular basis. You provide a manufacturer
and component part number, the name of the
CAD package and we take it from there. |

Custom
apertures can be accommodated but must be
accompanied by a detailed dimensioned drawing.
Note:
Aperture lists must be entered into our CAM
software in order to correctly view your Gerber
data. Aperture lists, when entered by hand,
are susceptible to human error. A more desirable
method is to use software to convert the supplied
aperture table. Circuit Graphics has software
to convert aperture lists output from the
most commonly used CAD packages to a format
recognizable by our CAM software. |
