RE: [CAD_CAM_EDM_DRO] Re: shielding for steppers

With the exception that an "improperly" crimped terminal might not fit into
the housing for which it is designed, I don't think that you'd have any
problem by using a plier to crimp the terminals to the wire, and soldering
them to the terminal is a plus. Now, this is for standard electrical
connectors. If you're talking about something like BNC connectors that
require a proper "impedance" it's a different issue. With these connectors,
you've got to be very careful that the wire is crimped properly so that the
impedances match.

|Hi,
|
|Thanks to all who responded. You guys are great!!!
|
|Now if we are connecting the wires to connectors meant for crimping
|tools, (and also for connecting to drivers, DB25, switches, etc.) and
|one doesn't have a crimping tool, is using the poor man's plier just
|as effective? And is there any harm soldering the wire to the
|connector (meant for crimping) as well?

|Thanks
