PCB Soldering Help Needed! Answered

Hey Instructables, I am going to be starting a project soon and need some help. I have very limited electronics skill and need to learn how to solder a certain connection. I don't have the board yet so I can't get good pictures of the board besides these. It is for a usb midi controller, but that isn't really important because the board is already set up for what I need.

This is the board I will be working with. My plan is to replace the buttons on here with old school arcade buttons. This means I will need to solder a positive wire and a negative wire to the connection under the rubber button.

Theese are what the connections look like on a different part of the board, so I assume this is what the ones I will be using look like.

My questions are:

How can I tell where to solder the pos and neg wires?

How would I go about soldering this?


Thanks a ton for any help you can give :)

For this kind of printed circuit board I would recommend soldering with temperature controlled soldering iron.  Temperature of iron can be adjusted with the front panel temperature control knob - you can precisely control the temperature of iron to within 9 degrees Fahrenheit. It makes your soldering task a whole lot easier. In addition, electronic temperature control allows precise control of the heat level at the tip of soldering iron. This means that you can rest assured that your soldering iron is hot enough and ready for soldering, and at same time you know that it is not too hot to burn some temperature-sensitive components on circuit board. There is soldering guide on website:

for this type of switching pos' & neg' don't mean any thing really. you need wire connections rising off the board.
if the tracks are on one side only, you could drill holes next to the exposed metal, insert copper wire and bridge with solder. you'd then secure with glue and have easy copper-pegs.
trying to solder fine wire directly would be a bit harder i think.
