1) When soldering the JTAG hack, is it best to solder the diode to two pieces of kynar (30 awg) wire, and then solder the wires to the points on the board, or to go with only one piece of wire, and solder the diode directly to one of the points?
2) I've noticed there are two types of points that I'll need to solder to (on the Xenon board) - pads that look like they have a blob of solder in the middle already (from the factory), and pads with a hole in the middle. Is there a tried and trusted method for soldering wires to each of these pads? Here's what I plan to do:
i) use cotton swab to cover pad with flux
ii) tin pad (possibly using a bit more solder for the pads with a hole in the middle?)
iii) tin wire
iv) rest wire on pad - heat both pad and wire with soldering iron (have a 30w iron - 3-4 seconds of heating?) - apply solder to joint
1. you can choose to do either, but sticking the diode in the hole could result in poking the diode wire through the hole and hitting the metal case , you don't want that (i used 2 wires on both ends on first go)
2. read the guide. fill up the holes with some decent leaded solder, it'll make it easy for you
your plan is very good, you have learned very good soldering basics. but a 30W iron could do damage if you're not very careful! it's really hot you could lift pads.
if you pre-tin the pad, and the wire, you're good to go and melt them together with just a touch of the iron.
It's your choice to use a diode on that point. It's not required, but it helps you get a good flashconfig (from what i've read).
I'm not sure about the 330ohm resistor. I have set up a falcon without one and it worked.. Well it does randomly RROD but a powercycle fixes this.
