SFE Footprint Library

2006-02-07T17:59:23Z

Lou:

This is the holy grail for [[http://www.sparkfun.com Spark Fun Electronics]]. Each footprint is a custom layout. This library has been compiled over 5 years and 100s of man hours worth of work. If you are a student, please, enjoy and learn. If you are a professional, please buy something from www.sparkfun.com to help us out.

Currently we use Protel DXP for 90% of our layouts. Eagle is also used but we don't create as many FPs. The zip file above contains only a Protel library. It does not contain even a minimal one for Eagle. (Is anyone aware of any format conversion utilities which might be helpful? --dave)

Please take all these footprints with a grain of salt. Most of the FPs we make are rather exotic and complex. We rarely trust an FP from anyone else thus usually creating our own.

List of current footprints:
*5-Lead DD PAK - Voltage regulator
*0603 - This is the basic 0603 footprint. Use this or 0603 - OLD1
*0603 - LED
*0603 - OLD1 - Original, tight 0603 layout. Works great, very minimal
*1206 - LED - This is a very revised, nice layout for 1206 LEDs including an expanded paste layer for a nice solid solder connection
*3216 EIA-A - Perfect for 10uF tantulum caps
*7343 EIA-D - Perfect for 100uF tantulum caps
*Antenna - 2.4GHz - This is the antenna found on the RF-24G devices. No guarantees it will impedance match
*Antenna - 2.45GHz - Chip antenna fp
*Antenna - SMA - Vertical mount SMA or RP-SMA connector
*Antenna - SMA - End Launch
*BGA-32 - 32 ball bga for the Analog Device's ADXRS MEMs gyros
*BlueRadio with Antenna - This is the FP for the Bluetooth module. No guarantees. It's a bit odd with restricted areas.
*CF Socket - Basic CF breakout. Start from here and make it fit your part
*CF Socket - Recommended - more silkscreen, wider solder pads
*CNZ1120 - Optical photo intr/sensor fp
*Coin Cell Holder 12mm - SMD
*Coin Cell Holder 20mm - PTH
*Connector Molex x - Vertical and right angle connectors with polarized connectors
*DB9 Headers - various DB9 connector FPs include PTH and end launch
*DIN-3 - DIN connector
*DIP connectors
*GM862 - Cellular module FP with antenna, pin1 indicator, and shield holes (proven, works great!)
*Headers - Various SIP 0.1" headers
*Lassen iQ - Couple FPs for the Lassen iQ with and w/o silkscreen lines (proven, works great)
*LCC8 - Special - Minimal FP for the ADXL series accelerometers from Analog Devices (proven, works great)
*LCD 16x2 - This is mechanical and electrical FP for 16x2 LCD from SFE. (proven, works great)
*LED Polarized - Simple T1, 5mm LED FP
*LED Polarized 3mm - 3mm LED fp, works ok. Hard to see silkscreen
*LFCSP - Recommended and modified FP for the newer ADXL32x series from Analog Devices. Recommended FP is proven and works great.
*microSD Socket - Proven, works great
*MLP-24 - Used for the nRF2401-ish ICs from Nordic. Proven, works great
*MLP-28 - Used for the CP210x USB ICs from SI Labs. Proven, works great
*PG31 - GPS receiver from Laipac. Includes silk area for MMCX connector.
*PIC ICSP Mini - This is a custom FP by SFE. It's a in circuit serial programming jack that is 1.5mm pitch. Used to program just a bootloader onto a board without using up the space of a full sized programming header
*Power Jack - common barrel jacks with silk and mechanical layers
*Power Switch - Common SPDT switch, can be used for power or signal
*QFN-16 - Used for the MMA7260Q triple axis accelerometer. Works great but has some interesting keepout lines to keep vias out from under the IC
*QRD1114 - FP for the QRD1114 IR line sensor
*QUAD44 - TQFP package for the 16F877A IC
*Radial Caps - Various FPs for radial caps. Be sure your part matches the various dimensions.
*RJ11 - Jack for ICD or telephone
*Screw Terminal - 0.1" pitch screw terminal, two position version has two peg holes for structural stability
*SD-MMC Socket - Just what it sounds like
*SJ-2503A - 2.5mm stero jack
*SMA - Diode - Good 1A reverse polarized diode
*SMD Cap - SMD eletrolytics. Use at your own risk
*SOD-323 - Very small diode, good for signals
*SOIC - various soic FPs
*Solder Jumper - NC - Normally closed solder jumper. The paste layer is expanded so during reflow, extra paste is available so the jumper is shorted
*Solder Jumper - NO - Normall Open solder jumper. Paste layer is there, but not enough for a short
*Solder Switch - handy for SMD switches just using a soldering iron
*SOT-23 - Commom BJT footprint with various configuration. Check the datasheet for your particular part.
*SOT-23A - FP for popular small voltage regulators
*SOT-223 - Bigger 1A voltage regulators use this footprint like the [[LM1117]]
*SOT-457 - Transistor array FP
*SPDT Relay - Couple relay footprints
*SSOP - Various SSOP footprints
*Stencil Peg - This is an alignment hole for the Stencil-Alignment-System as well as a stand-off hole.
*Switch - Various momentary switch FPs. SMD, PTH, and Right Angle PTH
*Terminal Block - Various screw terminal blocks
*TO-92 - Various v-reg and PTH transistor FPs
*TO-220 - Various PTH FPs including LM317, LM7805, and heat sinked FPs
*TRF-24G - Popular FPs for the RF-24G 2.4GHz module
*Trim Pot - Couple trimpot FPs
*USB - Various USB connector FPs
*WEEE Icon - The european initiative to limit electronics trash. It's an silkscreen icon that looks like a trash can...
*Xtal-2 - Standard crystal FP
*Xtal-6 - SMD Watch crystal FP
*Xtal-SMD8 - SMD ceramic resonator FP
*Xtal-SMD9 - SMD quartz crystal FP

Lou:

(There is currently no text in this page)

(I know, because I just checked.)

(This place used to be lousy with text.)

(Now, not so much)

Lou is a freaky dude who is trying to figure out where it's all at, man. Lou has just started referring to himself in the third person to see if it is really as annoying as it is purported to be. It is, but we haven't told him that yet. We will tell him right after the end of this list.

Lou is an old dude; going through his midlife crisis. Yes, that is supposed to come later. His came early. Bite him. Lou is nutty as a nut and sane as a square. Squirrels are strangely attracted to him. Squares, not so much.

Lou has been doin' the circuits-n-stuff thing forever. Always took stuff apart. Often got it back together.

Exploring their metallic and plasticy viscera.

Oh, come on, like you aren't weird too.

If you're a hot chick who's into electronics and/or computers, message Lou. Computer games do not count; though they won't count against you too heavily if you can use vi. Lou (not Paris Hilton) will be the arbiter of who's hot. You may be surprised.

Lou apologizes for the use of the word "chick" on this page. He was unable to select a better one at the time. To this day, he struggles with that choice.

Lou realizes that it is quite possible that no human female will ever read this page, which is really too bad as he fancies them quite a bit, really. Or maybe that is a really good thing. Yeah, probably.

Lou does not want a fight. He will cool it, whatever it is. He is a big wuss that way.

When lou dies, he wants it to be on purpose. Either his or somebody else's. Which makes sense, because the other options are accident, disease, and old age, and all of those are pretty terrible ways to die. At least with purpose, something has been accomplished for somebody somewhere. Otherwise, it has all been for naught.

Lou's internal id number is 4. He keeps hitting the snooze on his biological clock. He could not care less whether or not somebody posted before he did, and sincerely wishes that anybody who does care about such things would just die and leave the rest of us alone already.

Lou likes the AVR platform, though he has not yet actually built anything with it. The closest that comes to that is when he tweaked a Motorola WR850G enough to connect it to his AVR Butterfly and change the textual message on the screen when certain IO lines were toggled. He has just sent in an order to have some boards fabbed. One of them will host an ATmega8. Before AVR, Lou liked PIC for its simplicity, but that became its downfall. Why do they not make micros with lots of RAM built in? Particularly those which can boot over a network. A megabyte in a micro would be like the embedded programming version of sex. So lately, he has been looking at the embedded ARM offerings. They don't have that much memory onboard yet, but just wait until they catch on. Oh to dream of the day when Lou can power on his lump at the end of a USB cable and have it fetch a firmware image to become whatever device. That technology exists now.

Lou is the proud owner of a SAM7-H64 from Olimex, which he bought from Spark Fun. It is so very cute. It comes in its very own 4-color printed cardboard box. Maybe, one day, he will have some bootable code for it.

Lou wants me to make extra sure you know that he really digs the ladies a lot and remind you of the whole preceeding section on that. I have no idea why.

Lou is going to totally kill me when he sees this.

This is just un-called-for.

Lou does not know when enough is enough.

He really has no clue.

You can spell it out right in front of him using his own account, and he remains oblivious.

Lou is a god, baby, and doesn't care if you believe it.

He is not holding me at gunpoint right now.

No, I'm not just saying that to avoid having my head blown off.

Really.

Yeah.

Lou:

Copyrights have been so coopted by the recording industry, that they are now used as an offensive weapon, rather than simply to afford protection. Sony[sic] Bono deserved what he got. What happened to SCO, anyway? I bet Darl is still walking the streets a free man.

I, myself appear to have found that Jameco is good for small quantities of a fairly common part. They don't have anything surface mount, though. For that stuff, I had to go to Digi-Key. I called up Digi-Key to see if I could alter an order I had just placed before it got fulfilled. My order was already far enough along that they couldn't stop it. I believe the phrase was "too far gone". That speaks well of their order fulfillment process. I hear Mouser should be in there too, but I've never had a compelling reason to use them.

Radio Shack is a joke. So is X-10.

Pricewatch is good for locating certain computer gear at its version of the best price. Froogle is sort of the same thing, but without the seedy side filtered out. All Electronics Corp. needs to even out their stuff a bit. Either specialize in a few types of parts or be more even across the board. Spark Fun Electronics appears to be trying to do it right. It is still weird that I can't just order a bunch of 0603 resistors from them. Seems like a no-brainer.

I want to see some competition in the micro dev/app board market. I just paid approximately 34.95 + its share of the shipping for a 32 bit ARM microcontroller on a PCB and with a USB device port on one end and a series of header sockets on the other. If that is considered cheap, then this is never going to take off.

I realize that other authors will have different opinions than I, and that this entry is probably not going to remain as it is for long. Come on, everybody. These comments do not reflect the opinions of Open Circuits. They are only my own. Add yours.
