PCB Express
is my preferred PCB
vendor. I have done over two dozen boards (five large panels) without
problems. The service has been excellent, panelizing is not an issue
and the price for a large panel (12 x 14 inch) is reasonable.
On one order there was a Fedex problem with my PCB shipment and it
couldn't be tracked. PCB Express immediately made a second batch of
boards and sent them overnight delivery at no charge. I consider this
excellent service since the mistake was most likely made by Fedex.
The boards from the original order were delivered a few days after the
second batch arrived.
Distribution
FindChips (your new best friend)
From
FindChips ---
FindChips.com aims to perform the
fastest, most complete distributor search available today on the
internet. After you enter a part number (or substring), FindChips.com
will simultaneously query over 20 distributors, and return the
responses to you in real time, in the order completed. FindChips.com
searches distributor inventory for all types of electronics, including
passives, connectors, optoelectronics, and more -- not just chips.
Digikey
Digikey
has excellent service,
competitive prices and a better search engine than any of the other
distributors.
Although the search engine is good don't throw away your catalog
yet. When searching for connectors, switches, LEDs a good catalog is
much faster than the search engine. Some times you are better
off using the printed catalog rather than trying to guess the search
terms or go through an infinite series of click .. wait .. zoom-in
.. zoom-out cylces. Also, the Digikey search software does not
understand units of measure. 0.1 inches is treated differently from
2.54mm, dual is different from 2, etc. Company names are also
inconsistent in their database.
After you find the Digikey part you want type the manufacturer's part number into
FindChips to make sure the price
is competitive.
Mouser
Mouser
has excellent service,
competitive prices and a useless search engine. I use Mouser almost as
much as Digikey. The best way to find a part at Mouser is their catalog
or
FindChips (your new best
friend).
McMaster Carr
McMaster Carr
is your one-stop shop for almost
anything mechanical. Exceptional service. For standard ground shipping rates you
usually get your parts in one or two days!

Semiconductors
ON Semiconductor
ON Semiconductor
is the nuts-and-bolts part of the old Motorola. A
wide variety of semiconductors available at all the major
distributors including
Digi •
Mouse. Their component
selection tool is the best in the business. Their sample policy is
also the best in the business. For $11 S/H they will send you
a dozen different part numbers with quantities ranging from 25
pieces for low-cost parts to a couple for the more expensive parts.
ON Semi is my first choice for semiconductors.
Texas Instruments
Texas Instruments
makes a wide variety of logic, analog (including Burr-Brown)
and DSP components. They make the MSP430 ultra-low power
microcontrollers that are widely used in sensor networks. Chipcon
(radios) is now part of TI. TI is distributed by all the major
distributors including
Digi •
Mouse.
Linear Technology
Linear Technology
---
state-of-the-art analog parts with prices to match. Samples are easy
to get if you do not need too many (2 pieces of 2 part numbers).
Analog Devices
Analog Devices
--- state-of-the-art
semiconductors. Samples are easy to get and technical information is
the best in the business.
Maxim
Maxim
--- excellent single-function
as well as multi-function parts. Quality of components and technical
literature is in the same league as Analog Devices and Linear
Technology. Well designed website. You will be OK as long as you follow
these maxims ---
Maxim Maxims
- Do not add any Maxim part to your design that is not in stock at Digi • Mouse
- Do not add any Maxim part to your design that is labeled NEW.
- Ignore any Maxim part that is labeled FUTURE.
