    I am waiting for the tinning material to arrive :) . More pictures will follow.

    The scratches you see on the copper surface are because i use fine sandpaper to help apply tin or soldermask layer.

    Don't use sandpaper - I have found that it scores too deeply - try steel wool instead - much better surface. Deep scores produced with sandpaper alter etching in my opinion.

    I know.
    The one i use is not simple sandpaper. It is special for use with metal and i work it with soap water. I dont know how you call it in english.
    I will try steel wool next time, Thanks.

    Its wet sandpaper, typically black in color and has very fine grit - 400 to 1000 grit is common and is used often for rubbing down finishes in woodworking as well as in auto body work. I still don't use it for pcb's because we exert uneven pressure when sanding by hand and cut through too deeply in spots. Even when using a sanding block, I have found the edges end up getting knocked down first while the center needs more work. Steel wool for me only.

    Well i wouldn't say professional... but it is O.K.

    This board will last long trust me. We will probably not be around to see it failing, if you know what i mean ;)

    Can't complain with that ;) you should give yourself credit, it's easy to criticise your own work. It's hand made but it doesn't get much better than that.

    Well, like i said, it is OK for hand made. It can not be compared with a machine made though.
    It's just that for small projects like the ones we do, a better PCB would be an overkill.

    This is my latest board. I tined it by hand with a flat tip soldering iron and 60/40 solder wire. :)
