If you ever solder a header pin, and it VISIBLY looks ok, but the pin moves when you push on it, you need to clean the area, use a little flux, make sure you are using the right solder (pc rosin core works great), and that the iron is hot enough (if it doesn't smoke a little while you are soldering it is not hot enough). Your solder job should look like liquid mercury, nice and shiny!
Hey, but what do I know, I have only modded around 200 consoles, 99% of them using the header pin method

| 200 consoles! Now you're just showing off I'll assume the 1% that weren't header pin installs were on version 1.0's |
Nope. I know the actual number, but I won't say. 200 doesn't sound as overboard!
I actually use desoldering braid to remove the solder on the 1.0/1.1's, so that doesn't make a difference.
The other 1% are TSOP's. I even install the matrix and X1 with header-pins!

Yep.
Also, 60/40 Rosin-Core is about the best for electronics. If any of you are using solid wire and no flux, then you are gonna have a fun time resoldering all those cold joints over the years

| First, I digress... Did my (first) install last night. Took me about 2 hours. Alternate D0 gave me no problems. Header pins did give me problems. Everything looked fine, but I was getting (at first) no light, then later just solid red. MS Dash booted up like no chip was installed. Checking the voltage/ground on the pins is one way to check your problems. I noticed that pin 2 wasn't grounded...meaning bad soldering. Another thing I did to check was to push the pins from the top side and I was able to push the pins out even though they looked soldered. I resoldered the pins that moved and everything was good after that. Now, to the header pin tip: The modder I bought the chip from gave me a very useful trick that I've never seen mentioned here or anywhere else before. Adjust each pin so that they barely stick out of the bottom of the board. It makes soldering so much easier. With the normal length of the pins, it's a lot harder to make the solder suck into the hole. When the pins are almost flush, its easy as pie. |
This should be pinned... Helped me out a lot!!!! Xenium works perfect now!

Used flux on the pins. Unless you mean put it in the hole. (No alternate meaning intended)
Its a lot easier to heat the pin and hole when they are almost flush. Unfortunate inheritance of shaky hands from my dad.
A pro can refute any tip. But then again, a pro should be able to install a chip in 5 minutes with an iron (for shirts).

I didn't think about it, but this probably depends on the tip you are using. I prefer the "pointy" one, not the one that looks like a flat-head screwdriver

I suppose so... Not personally trying to refute the tip, just trying to see the science behind it. Technically the wire could go on forever, as long as you heat the correct spot to the correct temperature, use flux, the proper solder and the proper tip, you should be fine... (Basically just have the correct setup for soldering electronics -- not radiators!)

Use a file or sandpaper and you can clean it and shape it. Especially if it is copper, it works out rather well
After reading through this thread, I think just about anyone can not solder a pin-header without issue. All the bases have been covered
