First of all I know the surface mount board has no copper pour
I was just testing
Right I used a horrible cheep 1.6mm copper clad board
press and peel blue http://www.techniks.com/how_to.htm
cannon lbp2900i laser printer
gbc laminator http://www.pulsarprofx.com/PCB/a_Pages/ ... urces.html
#00 steel wool http://www.cleanyourcar.co.uk/accessori ... d_377.html
pure acetone not nail varnish remover
I was trying to use magazine paper but I was getting inconsistent results
I used a laminator for the same reason,I am a man therefore I can not use a clothes iron
I ran the board through the laminator 4 or 5 times.
I was using automotive scotch brite pads from the body shop at work but they make an awful mess.so I tried the #00 wire wool I had in my garage.
And all the nail varnish removers I brought localy were banned they had lanolin,wheat protein and all manner of lady nail friendly chemicals in.
To etch the board I used warm ferric chloride in a shallow plastic dish.
I cut a 3" square piece of micro fibre cloth and folded it into a small rectangle which I then folded ever the end of an old pen and secured with a zip tie.
I cleaned the board with the #00 steel wool and then wiped down with acetone.
I held the board (with glove) over the dish while I dipped the micro fibre in the ferric chloride and then gently brushed the board once or twice and then re dipping and repeating until I had remover the copper from the areas I wanted.
I then removed the toner with the #00 steel wool under a running tap.
Idea came from here http://www.pulsarprofx.com/PCB/a_Pages/ ... chor-49575
In the picture next to my initials jw you can see a small pit this was caused by a piece of dust between the press and peel and the board.
I had covered this with etch resistant pen but that did not survive the etching method I described above.
