which bottle is which?
« on: March 06, 2008, 04:53:20 PM »
well i just came back from buying the etching kit from radioshack but i dont know which bottle to use in step  3 and 4
Quote
Step Three: ETCH

*take the ETCH solution and put it into a dish (only half of the bottle)

*put the PCB in facedown with the design into the solution

*let it stay there for 15-20 min

*take it out

*pour water (take a empty gallon of milk and put water in it) and slowly pour water over the PCB so that the chemical will get off

Step Four: Solution

*take the other bottle labelled SOLUTION and put it into another dish (only put alittle bit) and put the pcb in face down

*turn it around after a minute and take a sponge and scrub at the black ink and it should come off revealing copper underneath

*pour water over the pcb as like before with the ETCH and you're done!

i got these 2 bottles from radio shack pc kit

resist ink solvent

pcb etchant

which one do i use for step 3 and which one do i use for step 4?

one more question do i really have to print the razors witha laser printer?

you should be able to use it forever, but i would recommend it. use it max of 2-3 times then get a new bottle
