[Elecraft] solder

[Robert Johansen]

I found an interesting article on the internet regarding Lead free
solder:

mamsg.pdf

Now I understand the reason why its use should be avoided for electronic
kit assembly. 

I have been using Kester 44 Tin lead solder for decades it has been
proven reliable, the solder joint has a mirror like finish and yes I take
the time to remove residual flux from the board it makes it easy to see
if I missed a connection or have a cold solder joint.

I found that Lectra-Motive CRC brand electric parts cleaner from R&S
automotive stores works great.  Do not spray it directly on the board
spray some into the cap removed from the top of the can, apply it with
cotton Q-tip swabs avoid getting  this stuff on plastic parts. Use in a
well ventilated area.

I used to use electronic grade flux remover anhydrous 100% alcohol but
the !@#$ Hazmat shipping charges from mail order because of the lack of a
local supplier stopped me from using it.
