I have tried to use Konica Minolta Photo Quailty Matte Paper. Then design your own circuit and print it on the Matte Paper. Remember, before printing it. You need to mirror board. Otherwise, the circuit will be inversed.
Step 1: Start to Iron It.
If some area cannot stick, it means your copper board is not clean enough. Remove the Paper and Use Acetone and Sand Paper to Clean it.
Step 2: Soak It with Cold Water
Please check the every trace. Find out any broke trace. If find, use Acetone to clean it and do it again.
Step 3: Etch It !
Step 4: Clean and Then Finish!
This PCB in the Photo are LQFP -80 14mmx14mm. The Trace is around 14mil. It is quite clean and no broken trace is found.
Originally, this method are tried by Karo-sama. He has made a video for demostration.
For more details , you can find it in my wiki.
