Has anyone seen the technique of soldering surface mount parts in a toaster oven.
 
I tried it and set off my smoke detector!

Went off on a tear today looking up and chasing down the 'skillet' technique of SMD assembly.  Found a bunch of material and decided to pull it all into a single document for my own use and then decided to put a pdf copy into our Files section just in case others might find it interesting.  The file name is 'SMD_Assembly_Techniques.pdf'.

SSS is this Sunday

Don't forget! The August Second Sunday Sprint is this Sunday, August 13th, from 7:00-9:00 pm. See the 4SQRP website for rules (under "Operating Activities"). This month's goal is twofold: 1) Let's have more than 10 participants; 2) Let's have the coordinator (me) remember to tally the scores when the contest is over!

Terry,


I use thin strips of 3M blue masking tape used by painting contractors, to strap the SMDs down to the board, but it may take just a little more time positioning one of the precut tape strips than moving the Doofus around.


Given your endorsement of the skillet technique, it would be nice if you'd give your audience here some of those details.


Advance TU es 72,


Charles, W2SH

Very nice Bill. 

Attached is one that I used when I first encountering SMDs while building KD1JV's ATS3.  Slide the fishing weight for more or less down force, easy peasy.  Still have the rig but the doofus has disappeared.

The skillet method is far superior nowadays.

Bob,

 

First SMD rule (Jim N5IB has touched on this) is no carpet.  There is a definite repelling force between tweezers and an SMD part.  This force will launch the part somewhere across your floor.  Chances are, it will never to be seen again if there is carpet. ;-}

 

Have fun and enjoy the build, SMD or not.

Very neat ideas - all of them. I haven't had to tackle a SMD board yet but no doubt that will be coming up soon and these all look like good ideas.

If I'd thought to look for those hold down devices, I'd probably have done it like that.  I like Steve Weber's one with the toothpick and also that bent wire job with a handful of fishing weights hanging off it to provide tension.  I might just have to build one of those out of a stick of that .050" music wire.  I have a set of special wire bending pliers designed for putting just those types of complex bends in the stuff.  My aluminum bar system, though elegant is probably totally overkill.  LOL

Jim's post reminded me I have some old photos of a few gadgets for SMD work. A couple by me, some from Steve Weber and others. The "famous" one is N4EEE's  "Goofy Lookin' Goose Shaped Surface Mount Holder Downer Doofus"  Google "SMD Doofus" and see what pops up.

I posted them to an Album in the Photos area "SMD soldering aids"

I like Jim's box with the sides.
There are quite a few parts still on the lam in the carpet beneath my work table  :^))

Very interesting idea Jim. Is the force of the wire that holds the components in place sufficient to damage them? I am going to make one but I doubt it will look as professional.

SMD soldering aids for small boards

Jim Sheldon
 

Having bought the EZ Keyer IIi SMD kit and also gotten several other
boards with SMD's on them I found that with my fat fingers, I needed a
way to keep the parts from bouncing off the board during construction &
especially something to keep them in place during soldering. In
commercial SMD board population, this is all done by precision machines
and, of course, those machines and the programming necessary, especially
for a "one off" board, would be totally impractical for any of us
amateurs so we have to muddle through or build some kind of aid to keep
the parts corralled and in place until they are soldered to the boards.

So far none of the kits I've built have had circuit boards larger than 3
X 5 inches so I made the tray fixture out of readily available hobby
woods from either Home Depot or Hobby Lobby,
For the hold down device, I used stuff I had on hand - an old heavy
steel base from an unrepairable, home made bug I scrapped plus some
surplus 6061-T6 aircraft aluminum bar stock obtained from a surplus
metals store in Wichita called the "Yard" store. It helped that I do
have a small table top milling machine and a bandsaw but everything
could have been done with a hacksaw and a file plus a drill and tap.

It got it's first use on the EZ Keyer IIi kit and worked so well I
decided to at least share the pictures of the fixture to the group's
photo's area.

Tried uploading the pix yesterday (followed Yahoo's directions) but they
would not upload. Funny but this morning everything worked and I was
able to get all the photo's uploaded. I hope they prove helpful, not so
much as a construction project, but as idea generators for anyone
wanting to do something similar.

4H and Hamfests

WA0ITP
 

Press release from Iowa

In July Dave C came all the way to Ottumwa to do a  SSCPO build session for the local 4H group.  It's great fun to help the kids out with the build.  He was here last year also, I helped, and I heard many positive comments about it from the kids and parents all year.  This year was a great success also, and will provide many nice conversations all year long too.

Yesterday Dave and I ran a 4SQRP table at the Cedar Rapids hamfest.  Didn't sell much but had a great time  seeing and visiting with folks we knew.  Seemed like Dave knew amost  everyone in the place.

Hamfests are great events to advertise the Four State product line, and to feel the pulse of buyer's needs and wants.  Anyone want the kit box and Banner for Joplin, or anywhere else?
