66113Re: [Electronics_101] Crimp terminals
- Dec 1, 2010True, many high reliability connectors are crimped, but not with
pliers like these:
instead they use something more like this:
If you have only the first kind of terminals and pliers, soldering is
probably more reliable. Let's hope the terminals take solder and
aren't made of aluminium because it was cheaper ;-)
A proper terminal applied with the right tool usually does not improve
in reliability with soldering, often the opposite is true, although in
some situations (automotive for example) crimped terminals are
soldered. Again the right procedure is required to avoid the problems.
