Wirewrapping
uses special wire wrapped around square pins. See Fig. 1
The corners
of the pins dig into the wire, forming an airtight joint.
Wirewrapping
is quick and cheap.
You can get
lots of connections into a very small space.
It withstands
vibration well.
Components are
re-usable.
However, it
is difficult to make it look neat.
Fig. 2 shows
a regular wrap.
Fig. 3 shows
a modified wrap, where some of the insulation is wrapped around the pin.
Modified wraps
are more vibration proof.
There are many
types of tool available, from a few pounds, up to several hundreds.
All usually
have some means of stripping the correct length of insulation.
Separate special
wire stripping tools are available.
When wrapping,
push the wire all the way into the tool.
Allow the tool
to rise up the pin under its own steam.Don't pull or push it.
Keep the tool
on the pin until the wrap is complete.
Avoid the following:
Turns wrapped
on top of other turns.
Spaced out turns.
Pigtails, where
the end of the wire is not wrapped but sticks out.
Loose wraps
i.e not tight around the pin.
Insufficient
turns.
Looking at Fig.4;
if it is necessary to remove a bottom link then two upper links must be
removed.
If you have
made wraps as in Fig.5 then you may have to remove ALL of your wrapping.
PLAN AHEAD. Don't change levels. |
