[Elecraft] Deflux?

Sat Aug 17 01:33:01 2002

Having worked in the electronics industry for many years, it has 
always been normal practice to clean flux off pcbs after work.  It is 
seen as bad workmanship to leave it there, and even (now I am in the 
TV servicing trade) a give away to others as to what has been 
repaired. I have never ever had problems with damage to components or 
plastics as a result of cleaning.

But I am staggered at what has been suggested for flux removing!  
Forget about using various concoctions from your local drug store or 
corner shop.  The proper materials are available for the job.  I use 
Electrolube Fluxclene (FLU400D) - I imagine an equivalent is 
available in the USA. This works well, but admittedly not as well as 
the old, now outlawed, Freon.  Get it from your electronic component 
distributor. Don't use a cut down paint brush, proper brushes are 
readily available from the same source, which cost peanuts and are 
less likely to cause static damage.

My K2 was cleaned in this way and is working fine.  There is nothing 
wrong in cleaning flux provided it is done properly.
