solder

[wb2srf]

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

http://www.jgpp.com/projects/lead_free_soldering/03_27_02_presentations/b
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.


73,

Have a nice holiday season

Hi Tom,
 
Thank you for correcting the hyperlink and adding the starting page.
 
The pictures and graph show another reason why we should avoid using Lead
free solder.
 
 
Merry Christmas to ALL, appreciate all of the comments,  it made an
interesting read for a soldering tutorial
