UltraCAD Design, Inc.'s Homepage
| What is Ultracad? | UltraCAD Design, Inc is a printed circuit board design service bureau located in the great Pacific Northwest. We specialize in large, complex, fast turn designs common in the video processing and data processing industries. Our customers come from all over the United States --- California to New Hampshire --- with over 95% of our business from repeat, satisfied customers. See special note below about our new relationship with Monsoon Solutions, Inc. | |

UltraCAD celebrated its 20th Anniversary on January 2, 2012. It has been 20 wonderful years! | |
| UltraCAD and Monsoon Solutions, Inc | UltraCAD has reached an agreement with Monsoon Solutions, Inc. (also of Bellevue, WA) whereby Monsoon will do all board design work for UltraCAD. Dave Graves has moved his offices over to Monsoon. Dave and Monsoon can be reached here. Doug Brooks will continue to be responsible for the rest of UltraCAD's business activities. |

| New Booklet on Sampling Distribution and Central Limit Theorem | In another life, our Doug Brooks taught Statistics at the University level. One of the hardest concepts for students to grasp is the Central Limit Theorem and the Sampling distribution. If a student gets these concepts, the rest of Statistics is pretty easy. But if he or she doesn't, well nothing else in Statistics makes much sense. Brooks wrote this booklet for his students (a loooong time ago) and has rewritten it for new students today. Check out more here. | |
| Engineering Tools | UltraCAD has just introduced a new
series of engineering tools aimed at helping the student or engineer with
specific types of problems. The first two tools are (a) a Fourier simulation
tool that illustrates and manipulates Fourier series for various waveforms
commonly found in electronics, and (b) an impedance tool that calculates
and works with series and parallel impedance combinations, time constants,
and resonant frequencies. Update: The Impedance Tool had a bug (now
corrected) that prevented it from running under Win7 64 bit OS. The Fourier
Tool download package now includes a Microsoft Graphics patch that most
users required for proper operation. |
|
| This new calculator will calculate
factorials, permutations and combinations for virtually any values. I have
used it to calculate the factorial of 10,000,000,000! (But a factorial this
large takes considerable time to calculate!) Read about it
here. |

Calculators & Tools |
UltraCAD Has developed several freeware calculators (and now four for-license calculators) for PCB designers. Calculator topics include transmission line impedance, crosstalk, relationships between trace current and temperature, and relating trace geometries (width and thickness) to equivalent wire gauge. A fifth calculator helps analyze the combined effects of bypass capacitor capacitance, inductance (and therefore self-resonant frequency) and ESR. A newer calculator does differential impedance and replaces our original calculator, introduced many years ago, that has gained acceptance around the world. Our latest calculator adds the Skin Effect to complex PCB calculations. Check our our calculator page here. | |
| Seminars | Check out the Seminars Doug Brooks frequently gives at various conferences
(including the PCB Design Conferences East and West.) These can
be offered at your site or in support of your organization.
Please e-mail Doug Brooks at
for details. |

| Simulations | Check out our simulations that we are now making available to the public | |
| Humor | Sometimes our imagination runs away from us (or maybe there are periods when we simply don't have enough to do.) UltraCAD has contributed several humorous articles to Printed Circuit Design's "Back Page" through the years, including the classic "Flying Electrons." Others included such things as smart electrons and why service bureaus should be paid by the government for NOT designing boards. Read all about it here. | |

| Partnering | Our statement on partnering has gathered a long list people who have endorsed it and embodied as their own philosophy, also. Check it out here. | |
| Price | We have some opinions about the difference between lowest bid and lowest COST. They are reprinted here. | |
