Sorry for the early bump, but here's a rough sketch of the schematic/pinouts:

Image

The capacitors are simple 3.3uF ceramics, and the resistor arrays are 51 ohm.

For those that don't know, a resistor array (network) looks like a group of resistors smashed together into one component. In this case, there's 4 resistors to a network. Each resistor in the array simply acts like a normal resistor.

Nice to see this in pictorial form.

Just remember, I did it first ;)

Now, how about we see how to make a permanent jumper pack.

What caps/resistors go where? :P

Now do you understand? :P

A face can say a lot. Especially if its yellow. :lol:

Now someone post pics of the port desoldered with some resistors and caps on it running oot!

Why wouldn't it?

Anyways, I recommend putting a razor in between each contact right before you solder to it to avoid shorts. Like: contact razor contact

That is what i did when i worked with the psp's small traces awhile back, its a flawless technique.

As sonic would say:

or is it you're too slow?

for my portable, i made a support for my relocated slot out of metal that is screwed into the sides of the board where there is metal coating and some screw holes, i was afraid that the supports might be touching a contact (even though they prob werent) and then I went so far as to wrap the metal pieces with electrical tape

will i have any problems so long as the metal supports arent touching any connections on the board?

A hint for those attempting this: be careful with the flux. I found this out the hard way on a different project. Flux is corrosive, that's why it works. In fine-pitch situations like this it's best to clean off the flux afterwards, even if it's a no clean flux, just to be sure. It also provide the advantage of helping to remove any stubborn little near-microscopic balls/chunks of solder that inevitably get jammed in between pins on something like this. Not to mention that some kinds of flux are actually somewhat conductive. :shock: So if you have mysterious random problems, check for fragments and clean your flux off.

To remove flux, I use 99% isoprophyl alcohol. I don't use rubbing alcohol because that has some water in it and leaves a residue. Dip a medium/hard bristle toothbrush in the alcohol, wipe of excess, and brush the contacts like brushing teeth. I find it works very well and cleans up soldering jobs quite nicely.

Frankly I don't understand any of those numbers you guys have been talking about. :(

All I need is a picture to tell where to solder things :P I'll just get some flux on the wires and be fine.


The problem is that the picture of the wiring that sifuf did is too blurry for me to see, all I need is a pic to be fine, does anyone have one that's clear?
