Okay, so I was reading about how to etch PCB's, and most of the tutorials said to drop your board into a tank full of etching solution. Then they said to mix it around or rock the tank or what have you to keep it reacting.
I then found a method where they suggest using a 3-M scotchbrite pad and rubbing the etching solution on the board.
Here is my improvement to that idea. Go to your local dollar general (not family dollar) and head to the cleaning supply section. They have in there a device made of plastic, with the same exact scour pad on the end. The neat thing is, the device handle is made to hold dish soap, but you could possibly load it with etching solution. It has a small hole at the back side of the scouring pad, so as you push, the solution comes out. It keeps your hands out of the chemicals, and lets you put a little more elbow into the motion. it also has handy little measuring lines, so you can fill it precisely. Oh, and it costs like $2 last I checked (last Thursday).
I think it would be worth looking in to, but I don't have any boards to etch, so someone try it and let me know how it goes.
Hope that speeds things up at least a little bit for you guys. I'll be on the look out for more tricks and improvements as I lurk around the forums more.
