Microelectronics PCB Soldering or,
The Idiot's Guide to Attaching a Modchip (v0.1) - Thanks To Xbox-scene.com
Tutorial written by : Xev
This tutorial covers all things soldering; look elsewhere for answers
to your other questions...
Please note that the pictures here are not of an Xbox, and really
could be of much better quality. When I install my X2, I'll take
new pictures with a friend's camera. (Mine is really shitty... if
you like this tutorial, how 'bout sending me a new camera? ;) )
1) Okay, I Want a Mod Chip. Why Should
I Solder It?
If you want to install a modchip, you currently have three choices:
solder it, use pogo pins, or have someone else do it. If you can
get option three for free (all of my friends have! ;) ), go for
it! Chances are that if you're reading this tutorial, option three
will maximize your chances of success.
Next up in terms of ease is option two - using a pogo pin adapter.
The trouble with this method is that while pogo pin mods are generally
easy to install (by virtue of being solderless), they were really
only designed for temporary installation and have a tendency to
drift out of alignment, causing more grief than they're worth in
the long run. If you want to, er, "spring" for pogos because
of an unresolved fear of soldering, then I'll refer you to Appendix
A, "Directory of Competent Psychotherapists" before you
commit to a decision. If, however, you are merely a bit nervous
about taking a hot iron and molten metal to your beloved Xbox, then
relax - soldering is fun and easy, and this guide is for you!
Still here? Solder and wires still in hand? Great, let's get started!
2) Disclaimer
I'm not prescient, nor do I have the supernatural power to protect
you from yourself. Use this information at your own risk. If you
screw up your Xbox, even while following my instructions to the
letter, don't come crying to me. TRY THESE METHODS AT YOUR OWN RISK!!!
That said, the risk is really minimal, so don't worry.
3) Equipment
To solder on a modern PCB (Printed Circuit Board)
like the Xbox mainboard, you'll need the right tools. If you're
reading this, I'll assume that you don't have access to professional
soldering equipment, so in our case the "right equipment"
is what is readily and cheaply available at the local Radio Shack.
Absolute must-have equipment:

15-Watt Soldering Pencil with Grounded Tip $7.99 RSCN 64-2051
A "soldering iron" will NOT do - the tips are too large,
the power output is often way too high, and the irons themselves
are rarely grounded. Spend the eight bucks and save yourself the
$200 for a new Xbox.

0.032" Diameter Lead-Free Solder $2.99 RSCN 64-025
Repeat after me: small diameter equals more control.
Equipment you probably should buy
but can live (dangerously) without:

Adjustable Wire Stripper/Cutter $2.99 RSCN 64-2129
Great little tool for the price!

Desoldering Braid $2.99 RSCN 64-2090
For repairing those "oopses." REQUIRED if installing an
LPC header in a v1.0 Xbox.

Anti-Static Wrist Strap with Cord $4.99 RSCN 276-2397
I highly recommend investing in AT LEAST this cheapass wrist strap.

Equipment you should get if you're doing this more than once:
Electronics Anti-Static Service Kit $19.99 RSCN 276-2370
Anti-static mat, wrist strap w/ coiled cord, and grounding unit.
A great deal for twenty bucks, as the professional equivalent goes
for about $150. (You do get what you pay for, of course...)
If you are installing an LPC header to allow an X-Ecuter 2 (for
instance) to be easily plugged and unplugged, you will need the
desoldering braid. If you decide to be cheap and daring and don't
go for one of the anti-static options, BE CAREFUL and ground yourself
before touching anything inside your Xbox. Chances are slim that
you'll actually zap your Xbox, but if you do, it's good-bye and
farewell...
4) Get With the Soldering, Already!
Plug your soldering pencil in and let it heat for a few minutes.
Careful! It will melt plastic, carpet, upholstry, small animals,
etc.
General tips to keep in mind:
* A little dab will do ya! When soldering wires to those tiny
little connection points on your Xbox mainboard, use only enough
solder to form a small bump that is the same diameter as the connection
point. Such a connection may look fragile, but it will hold... we're
not building a suspension bridge, after all.
* Heat connection points on the mainboard only just enough to melt
the solder. Too much heat can damage both the board and the chips.
(This isn't much of a worry for an LPC modchip installation as all
of the points are located well away from sensitive components)
* Keep the soldering pencil clean and free of solder by periodically
wiping the heated iron against a wet sponge or cloth.
* Touch only what you need to! That mainboard is fragile, and damaged
traces are difficult to repair.
I) "Tinning" wires. Difficulty
- EASY
Ideally, your wires will come pre-tinned. If not, or if you need
to make your own wires, you need to tin them before soldering. Tinning
is simple - you merely apply a small amount of solder to the wire
in order to "prime" it, so to speak.
1. Strip the wire, exposing about 1/8" of conductor.
2. Holding the wire in one hand, touch the tip of the soldering
pencil to one side of the conductor and apply a small amount of
solder (using your third hand) to the opposite side of the conductor.
Note that the conductor is melting the solder, not the iron.
Any solder clinging to the pencil may be removed by wiping the
heated pencil against a damp sponge or cloth.
II) Desoldering connections or header holes. Difficulty - MODERATE
If you are removing a previously-installed mod chip or are installing
an LPC pin header in a v1.0 Xbox, you'll need to remove some solder
before proceeding. I'll tackle two different situations:
a) Desoldering a wire connection
1. Place a section of unused desoldering braid
against the solder connection
.
2. Carefully press the tip of the soldering pencil against the desoldering
braid, directly over the solder connection you are desoldering.

3. The solder will melt and wick into the braid. While still hot,
remove the braid.

4. Touch the tip of the soldering pencil to the connection point
to heat any remaining solder and remove the wire.
b) Removing solder from a header hole
1. Place a section of unused desoldering braid
against the filled header hole.

2. Press the tip of the soldering pencil against the desoldering
braid, melting the solder beneath and wicking it into the braid.

3. Repeat as required to remove all solder.

III) Soldering wires to filled header
holes. Difficulty - EASY
If you're installing an LPC mod using the wire method,
most of your connections will be of this type.
1. Touch the tip of the soldering pencil to the
silver (tinned) circle that surrounds the hole.

2. When the solder in the hole melts, slowly insert the tinned wire.

3. Carefully remove the soldering pencil and hold the wire in place
until the solder solidifies.

That's it! You're done!
IV) Soldering wires or a pin header
to clean header holes. Difficulty - EASY
If you're installing header pins in any Xbox version
or using the wire method for an LPC mod in a v1.1 Xbox, you'll use
this method.
NOTE - To install header pins, all solder, if any,
MUST FIRST BE REMOVED FROM THE HEADER HOLES!
NOTE - Mainboard must be completely removed for
this method.
1. If untinned, strip wires to expose approx. 1/4"
of conductor and tin. Header pins do not need to be tinned.
2. From top of mainboard, insert wire or header pin assemby through
header holes.

3. Turn mainboard over. Touch the tip of soldering pencil to the
silver (tinned) circle that surrounds the hole, and apply solder
to the tinned inside surface of the header hole near the tip of
the soldering pencil.

4. After a few moments, the solder will begin to melt. Once this
happens, continue to feed solder into the header hole until the
entire hole is filled. DO NOT OVERFILL!

5. Remove soldering pencil and hold wire or header assembly in place
until solder solidifies.
V) Soldering wires to those itsy-bitsy
little pads, vias, and test points. Difficulty - DIFFICULT
For those extra wires or ALL 29 for you homebrew shmucks...
NOTE - Good lighting and a steady hand are highly recommended.
NOTE - These connection points may be located on the underside
of the Xbox mainboard!
1. If untinned, strip wires to expose approx. 1/8"
of conductor and tin.
2. Prepare the connection point:
* Touch the tip of the soldering pencil to the connection point's
(tiny) silver (tinned) circle or pad.

* Gingerly apply A TINY AMOUNT of solder to the connection point
by touching the tip of the solder wire to the point of the soldering
pencil.

* If done properly, there should be a small solder bump of the same
diameter as the connection point.
3. Position the wire flat against the mainboard, with the tip of
the wire touching the solder bump and aligned in such a manner that
the conductor will not come in contact with any other connection
points.

4. Touch the tip of the soldering pencil to the edge of the solder
bump. When the solder melts, carefully slide the wire conductor
into the solder.

5. As soon as the solder melts into the wire, remove the soldering
pencil while CAREFULLY holding the wire in place. When the solder
solidifies, the connection is complete.
