It is a toner transfer but I changed toner cartridges about a month ago and for some reason I get smudges here and there. With the toner cartridge I had the transfer paper came out GREAT. Nice straight lines, NO SMUDGES. Very clean. I even did some .006 traces that came out clean.
After printing then laminating pattern to board I ended up having to touch up the traces here and there. NEVER had to with previous cartridge.
It prints on paper pretty good so I don't think its a dirty something?
Before doing any more boards I hope to solve the problem without using to much toner transfer paper.
Oh yea I couldn't find my extra fine sharpi at first so some of the traces are way to big and not very straight.
About the only thing that worked really well was the alignment of the traces from one side to the other.
Contemplating on making another board IF I have some 2x copper. If not going to etch a daughter board for an LCD and another for a MAX6675 temperature compensation chip (used for thermocouplers)
Yea its one ugly board with lots of mistakes dealing with the traces. Thinking of moving the ADC/SERVO (A0 &A1 ports) over more to the left of the header. Might eliminate half of the LEDs(have the red LEDs for a LOW port and green LEDs for a HIGH port output.) Re-thinking that idea.(I wanted to determine the state of the ports RA2-RA5 HIGH or LOW?
