Soldering beast: 0.5mm SM

Hi,

I am at the middle of my new project, stopped with the problem of soldering some connectors:

this:

and this:

http://www.sparkfun.com/commerce/produc … ts_id=9105

I first searched to find a PCB ready for that in local mobile markets(even with more quantity of pins) and failed.

Next I bought a marker with 0.1mm tip and challenged for some days to design “own” PCB and again failed, as even though the ink is etch resist, the drawn lines are unreliable and become unattached from the board during the etching.

The last idea I have is to use ribbon cable:

and solder it from one side to the connector, cut it from the other side and freely use wires (must be easier to solder them). This way to use the ribbon cable as a converter.

but I don’t know if the width of the conductors is small enough for this application (i.e. 0.15mm as needed)

please give ideas if this would be practical at all, or may be you know what is the best practice to perform this surface mounting in home conditions.

Thank you!

Um, why not design your own PCB and have it made by BatchPCB for a few dollars? 0.5mm is pretty fine pitch to try to etch yourself, although it can be done with practice.

Using photo-etch, I don’t have any problems making PCBs at home for connectors like that.

Yep, I've done that sort of thing with iron-on "Press'n'Peel" laser printer sheets, but these days I pretty much send everything out to be made properly. If you can afford to wait, it's so much nicer than mucking around with chemicals, drilling etc...

They have numerous small PCBs that adapt SMT footprints to 0.100" footprints suitable for breadboard or other use. While I doubt they have something that would exactly match that connector, they probably have something else at the right pitch that you could modify to fit your need.

Also google around for “schmartboards” and see if anything there will work.

Could please explain more, or suggest any tutorial where I can start photo-etching?
