What did I do wrong to my pcb?
Hi guys! Im an electronic student and I want to know what went wrong on my pcb etching when I ironed it
Im creating a regulated power supply for my project
What happened is I scrubbed the copper with steel wool then I cleaned it with acetone. And then I placed the paper and maximize the heat on the iron and pressed it with the paper. After 10 min, i put it in lukewarm water, and waited 20 min before rising the pcb . But the thing is that everytime i put it in water, pockets start to appear and it would fail.
I have this for 3 times and the result is always the same.
The reason I print it on a magazine paper is because there is no available heat toner transfer papers locally in my area. Also when I buy online. Its always folded or curled and so printer shops in my area wont accept it.
Any advice how I do it. Should I redesign it?
