[TowerTalk] Cordless solder irons

[Don]

Two pretty strong statements.

I'm sure the folks at the marine fleet electronics repair shops I've visited 
along the coast here in Orygun, who seem to be unaware that they are 
'forbidden' to solder RF connections, would be interested in this 
information. I also observed the use of crimping RF connections is growing 
in some of the larger marine electronics shops, although for some it appears 
to still be a relatively new process. In a couple of the smaller shops I 
visited, soldering looked to still be the standard.

Don't know about anything about the aircraft electronics repair shop folks, 
out of my sphere of knowledge. But, I would suspect that the standards 
relative to RF connections in aircraft is more delineated for obvious safety 
reasons.

The folks who were  involved in the sat system installation at my home used 
only crimping tools and methods, so crimping is obviously appears to be the 
'standard' in this sector.

The Davis paper was well done IMHO and I thought presented a fair view of 
both methods pros and cons.

Before someone thinks I am anti-crimping, I agree crimping is a sound method 
done properly (like soldering). Were I doing a lot of RF connections I'd 
sure consider investing in the needed tools and new connectors. But I've 
only got one or two to deal with now and then and have lots of time and 
patience (and connectors). I've also 60 years ham and work experience in 
soldering typical UHF connectors, including N's  - but admit I don't get it 
exactly right from time to time. Probably wouldn't with a crimping tool 
either!!

So, Roger and Bill, what are the industry, trade or government documents 
that you state require only crimping of RF connections in the aircraft and 
marine industry?????

REPLY:

Same thing is true for marine wiring. Solder is forbidden, crimped
connections only.
