Richard, I already sent you my comments directly
as you requested, but feel I should respond to some of the comments posted here. By way of background, the only SMT parts I had used previously were mounting 5 SMT caps on an Inrad roofing filter kit for my Orion. That went well so I began looking for another SMT kit to try. I decided to try KD1JV's AT Sprint II which is described here: http://www.al7fs.us/AL7FS5ATSprint2.html The ATS-2 is a quasi-competitor to the KX1 in that it covers 80/40/30/20 and comes in a very small lightweight package for $205 shipped. I was particularly interested in the weight since I've gotten interested in the Adventure Radio Society's Spartan Sprints, which place a premium on weight. My ATS-2 including paddle, earphones, modules for 80/40/20 and a 9V battery (good for 2.5W for the 2 hour Sprint duration) altogether weighs 0.59 pounds. Steve KD1JV has now ended production of the ATS-2 in favor of an ATS-3 which should be even lighter! Construction was really a non-event and it was actually fun to build. I was initially worried about the AD9834 DDS chip which has extremely small leads but even that was no problem. The only trick to SMT is to use the proper tools--a magnifying visor (I got one for $4.95 plus shipping), 0.015" solder and a needle point tip on a standard solder station (mine is the $35 Circuit Specialists version) are the only musts . Special SMT soldering equipment is NOT needed. I also did NOT use any hold-down device although it is very easy to construct one with several web references (one on AL7FS's site above). Bottom line for me: SMT is nothing to be afraid of if you use the proper tools (which are neither expensive or specialized). I'm now just waiting for KD1JV to bring out his ATS-3 and get my weight down WELL below 0.5 pounds for more Spartan Sprints. 73, Bill W4ZV (K2 #4119) _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

A "trick" that I learned was to take a long piece of solid "bell wire"
or hookup wire (copper) about 6- 8 inches long. Remove the insulation and wrap a coil around your soldering iron tip. Bring the last bit of wire out, parallel to the axix of the soldering iron. Plug the iron, in, let the wire heat up, cut the "tip" to the length you want and you have a very fine tip for soldering SMD devices. I wouldn't want to build a kit this way; but if you only have a couple devices to solder it works pretty good. 73 de Larry W2LJ - Vivat Morse! © ® [hidden email] http://www.qsl.net/w2lj ARRL Lifemember QRP ARCI #4488 NJQRP #47 FISTS #1469 QRP-L #778 FP #612 QRPp-I #759 ARS #1528, AmQRP, CQC #746 K1 #1647 - K2 #4090 for QRP Icom IC-751A for QRO Butternut HF9V and G5RV antennas ----- Original Message ----- John Payne wrote: > Who needs an expensive "soldering station" for SMT?

As I said, I think the "soldering" part would be the least bothersome part of
assembling SMD board. (PROVIDED...the assembler KNOWS HOW to solder!... this was one of the BIGGEST problems I encountered fixing Heathkit stuff other people put together. Some looked like they used a heated mail for a soldering iron!) The biggest problem would be positioning and handling the components!

Ron You usually do not get identification marks on chip capacitors, melf/SOD80 diodes or SOT23 parts (transistors etc) This is what I see as the biggest issue to SMD kits as there is no visual way for the builder to validate he has the correct parts in the correct place so its all down to getting these in the right place first time. This might seem to contradict some of my earlier comments in some ways but of read in context it only means you need to concentrate a little harder and employ a slightly different methodology for the assembly of the 2 technologies. I already know 1 builder who had some problems that ended up being a misplaced part, a very easy thing to do. The part size chosen for a kit will make a big difefrence in parts managability but will make the inventory for compiling the kit for sale as you cannot sequence the parts as easily on tape as on a bandolier.

Nope. Those are smaller than anything I've used!
Yeah, I'm aware that many (most?) of the numbers I've seen have nothing to do with any parts I.D. conventions that I know! As a technical writer I work in metric all the time. I have to convert back to English more than go the other way. Most people here don't realize that the standard system of weights and measures in the USA is metric. We converted by an act of Congress to Metric over 100 years ago. The problem was that Congress didn't make the old English system illegal. Still wish they would <G>.

Everyone seems to be missing my point, which is, all of these things are
designed and fabricated in metric specs. The machine tools are made in factories to metric specs, but when the but the dials on them or the labels on them they are converted to english so we sad american masses who just cant/wont work in metrics can understand. I can, for example, make a 1/2" bolt by makeing it 12.7mm. My point is, the machining specs are actually in metric, but the end result is marketed and labeled in english.

Yes,
I think we can do simple kits with 1206 parts with home hand tools and possibly a hold down fixture home made. In fact, that would be a great "kit", a set of SMT sized tools: Needle Nose pliers, light spring tweezer, hold down device that would sit on desk and exert weight on a 1206 component as you soldered it, Maybe a Spudgeon tool, or dental wide tip blade to apply flux to hold 1206 as a "glue" until soldered, a roll of 0.01 low melting point solder, and list of suggested fine tip irons, and desk magnifiers that a ham could locally procure. Or include an option of that rectangular desk magnifier with tube light I have seen in some catalogs. These tools might be along the lines of the SMT article in the last QRP Homebrewer magazine, and any others you might think useful. Also useful would be test leads to fit standard banana plug Fluke and other import meters, but have real needle tips for SMT lead probing and test.

SMT:
Actually, you can use your present soldering station if it is heat controlled, and just get a smaller conical 750 degree tip for the Weller, or Ungar lines. For home use, this works for 1206 components well enough. The secret is to not apply heat too long, you are not soldering like you did with leaded components and trying to melt a whole pad. You are "tacking" down the 1206 one end at a time after centering it on a pretinned pad. A simple 25 watt iron could be used if you got or made a suitable tip of copper. A larger wattage iron might work well if you put a diode in series with hot side of AC line to limit the voltage and thus wattage. For simple projects, it is NOT necessary to use the hot air gun, or reflow solder tank. -Stuart K5KVH _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Sandy,
What kind of soldering station do you have now? How about $5 to put you in SMD capable soldering set up? Or maybe $10 outside, the cost of a proper tip if you have a heat controlled station now. 750 tips would do it, with the narrow end suited to 1206 pads. 73, Stuart K5KVH _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I would *love* to see an SMT version of the KX1. Already, in a number of
places in the current kit, it would seem like an SMT bypass cap would fit better than the leaded version! And probably no more difficult to fit/solder in place. How 'bout an "SMT Option" on some kits? 73, Steve aa8af _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

For manual SMT parts, 1206 is a workable size: 0.12 in. by 0.06 in.
