I should have paid attention to the warnings - I should have worn protective clothing - but you learn by your mistakes....
Developing a PCB in a bag containing the Ferric Chloride solution - managed to get a hole in the bag
Some of the stuff seeped out...
I cleaned up and tidied up - all seemed fine - then a couple of minutes later...
Ouch, Ouch, F***ING OUCH!!!!
I forgot one small brown stain on my right hand - littl efinger right in the first joint of the finger (I washed my hands by clsping them together and not cleaning each finger in turn - hence a small chemical stain got into the folds of skin
Result - small Chemical burn... stained brown
Lesson learnt.....
And.. what is the best way of getting rid of etch resistant pen after developing - I am getting pi**ed off rubbing the board with a copper "rubber" or a brillo pad - it takes ages... (water or no water)
