[Elecraft] soldering SMD's

[Don Wilhelm]

Mike,

Tom Hammond (SK) wrote the assembly instructions for that kit and 
included detailed instructions for soldering SMD parts.  I suggest you 
try that method before investing in solder paste or any other special 
tools.  You can fine the instructions at Tom's website 
http://www.n0ss.net/k6xx_cw_tun_ind_smd_v2_assy-align_k2_ver.pdf

I use a variation of that method.  Instead of any "holding stick", I use 
tweezers to pick up the part and hold it in place on the board. Be 
careful not to apply too much pressure to the tweezers or you will 
launch the part into unknown places and it will become vacuum cleaner 
fodder.

I put a bit of solder on one solder pad for any particular part, then 
position the part and re-melt the solder to tack the part in place.  
Then I solder the other leads and if necessary go back to the first pad 
and add a bit of flux and solder to assure a good connection.

The use of small diameter solder will help allow you to more easily 
control the amount of solder applied.

I have been reading on the internet about ways to instal these comments. I have read about using solder paste as this helps to place them and kinds steady’s them while soldering. Any thoughts on this method?? The only SMD work I did was on my K3 with the DC mod for powering the P3 with the K3. The soldering job was not pretty at all any input on soldering SMD's would be appreciated.
