[NTLK] :Re: Plan for Performing eMate 300 Hinge Repair

[Allen Russell]

I would just add:  if you read Frank's site you know the repair is required.

Forrest's instructions are good, but soldering does take practice.  I recommend youtube to see how it's done.  It's easy to use too much solder and make a mess, usually because the solder is hot, but the wires are not hot enough for the solder to flow.  Practice on something that's not an Emate.

And this is a good write-up:

It?s a good idea to ?tin? the tip of the iron the first time you use it. This ?tinning? is nothing more than applying solder to the tip and allowing it to melt?of >course, once it becomes hot?then wiping off the excess with a rag. I like to tin the tip a couple of times.

Re->soldering is much the same, except you are now holding the wire to the terminal you want to connect with, and touching the hot iron to that joint. In most cases you will >not need any additional solder to make that union.
