We can generate formal Autocad, CADSTAR,
Circuit Creator, Circuit Maker, Electronic Work Bench, EZ-Route, ORCAD, PADS,
PROTEL or Tango Logic schematic drawings from engineering hand sketches and
spec sheets, or email us your preliminary CAD schematic drawings and we can
finish them quickly, generate a netlist and BOM and email them back to you
for checking. If you don't have a schematic CAD package and we design your
schematics, we will give you a netlist, 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
To most companies, but not all, board
size, layer stack-up, component type, placement and routing is extremely
critical. 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, imbedded vias, shielded fast clock routes, fixed matched pairs,
complex analog/digital multi-split VCC/GND planes, .040 dia, .100 spaced IC
test point placement. After compiling your supplied net-list 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. We can import directly into our PADS CAD
system your mechanical .DXF file, to show fixed component locations, height
restrictions, route/component keep-outs, tooling and board outline, Etc.
Meticulous attention is given to all aspects of the design, including the often
neglected 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. A back annotation file is supplied here
to automatically back-annotate your CAD schematic.
Engineering Change Order (
Not as difficult as you may think. Archive
back-ups of all PCB revs are maintained here with a copy supplied for your
office. ECO changes can be made at any time during the PCB design layout
process. Unscheduled, complicated, mid-design changes will affect both
pricing and delivery differences. In most cases the design change procedure
is begun by simply submitting a PADS ECO file extracted from PADS Logic or
ViewLogic Systems, which will be compiled against a copy of the PCB design
requiring changes. We have 24 Hr. email and internet access
Another method for making changes is to submit a new revised net-list, such as
Orcad Logic. This will be compiled, in PADS, against the old PCB design.
Using the automated ECO file generation utility in PADS which creates the
always necessary ECO file. These are the primary, unfailing routines for
making electrical changes to your PCB design. It assures that the ongoing PCB
design is at all times 100% compatible and in-sync with the engineering CAD
schematic. A differences report between the old PCB design and the new
net-list is provided. However, being very flexible, we can make last minute,
time-saving "on-the-fly" additions or deletions of components and
connections to the design. We can create custom dual footprint components. We
can also add board mounting/tooling/potting holes and fiducial that are not
in the net-list. We have always been very flexible to serve the customers needs.
We have dedicated engineers and
technicians who 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.

How we could Serve you better
Initial Inputs with complete Information
of all parts is required. Layout Guidelines and or Specifications to be part
Adjustments could be made to make the flow of information ripple free. Preferences
for information exchange for initial inputs be provided to us. We always
offer a first on line service to our clients. We accept work and new clients
only when we can offer a first on line status. Delivery schedule depends upon
the Inputs and the complexity of the design.
