Board layout is important at Circuitsville.
We don't simply push the auto-route button and go for coffee.
In fact the version of EAGLE PCB Layout software was specifically chosen
because it did NOT have an auto-route feature.
Because the engineers at Circuitsville understand what causes problems in the circuits on
PCB boards and how to avoid them.
We have seen other layouts where an inexperienced engineer really caused major problems.
Whether it was routing the DC supply voltage under the tuning inductor of the
voltage controlled oscillator,
inadvertently maximizing the signal coupling.
Or putting the narrowest trace where the current would be the highest,
creating at best a high impedance and at worst an unintended fuse.
We have seen it.
For high current traces to be as fat as possible.
For surface mount ICs with the best possible PCB heat-sinking.
Or to minimize crosstalk.
Call Circuitsville. We understand circuits and we understand Printed Circuit Boards.
Plus we know the pitfalls and traps of EAGLE.
If you have invested six months of work in creating custom libraries you would not want to
erase that, would you?
But when you install a new version EAGLE erases the entire library directory before
installing the new version.
But we at Circuitsville have shed those tears,
we know how to protect your work and our work so that the libraries are there
when you need them.
An Example of board layouts done in EAGLE (by CadSoft Computer, Inc.):
The Servenger LLC, Programmable Analog Module: PAM 5002 (top view):
- RoHS Compliant
- Four Layer PCB with Split Power Plane and Split Ground Plane for noise isolation
- Surface mount (SMD) Components on both top and bottom, through-hole components on top only.
- Total of 216 Components in an area 3.1 by 2.9 inches (78.74 by 73.66 mm)
- Passive SMD components of 0805 or 1206 size
- Designed for automated assembly and wave solder. (Designed to minimize manufacturing cost.)
- Nine numbered revisions in the evolution of the product. (Eight before the version shown.)
- Hand-Optimized routing (no auto router used) to achieve optimal analog performance.
In addition to layout, each version was provided with:
- Creation and maintenance of the Bill of Material (BoM).
- Creation of instructions for hand prototype assembly.
- Hand assembly of several prototypes.
- Loading of Firmware.
- Functional Testing of all analog channels.
