[Elecraft] Full kits,

[Harry Yingst]

I've found that surface mount is not that hard just different.
Probably the same as when electronics switched from Tubes with point to point and big irons to PC boards with IC's and and smaller irons.
In a lot of ways surface mount is easier, (no leads to bend, reshape and trim)

I do have to agree It does seem that other hobbies are taking the lead in going to surface mount.

tl:dr I like to build things. Getting all the components 
assembled in a kit is a wonderful step forward toward the fun part.


I have built several kits with SMD components using just a 
temperature controlled soldering station. I think I could get by 
with a cheap Radio Shack soldering iron, but I certainly don't 
want to. (I like automatic spark advance in my car as well.)

The basic approach is to tin the pads on the board with solder 
and clean things up so there are no bridges. Solder one 
end/corner of the device and adjust it so it lines up with all 
pads. Then go and solder the rest of the pads. This technique 
works well with 8 pin devices. I would be in unknown territory 
soldering a 400 pin grid array device. :-)

I bought a hot air rework device from SparkFun 
<https://www.sparkfun.com/products/10706> for $115 which I use 
when I have to remove a SMD component. The video on the page is 
a good introduction to removing SMD components.

I will note in passing that the mantle of electronic 
construction has moved from the ham community to the builder 
community. Their suppliers are now the best place to learn how 
to deal with modern electronic components.
