Photo Resist PCB making with Inkjet Print on Transparency

Abandoning Heat Toner Transfer Method.....too unreliable, not very repeatable!!
Switching to PhotoFabrication of PCB:
Using an HP Inkjet Printer, Transparency Paper for HP Inkjet Printer, Hi Res Print Setting, Single Sheet of Transparency to Mask Photo Resist Positive Board, 60 Watt Compact Fluorent Bulb at the 8-inch Range for 5 minutes, Developer for 3 minutes (maybe a little more), and Etching for about 25 minutes (to get last stubborn piece of copper dissolved that is exposed), scrub of protective Photo resist with simple greeny....

Results were Fantastic the first time....this was a Test.

Are you using MG chemicals brand presensitized PCB's. Reason I ask is they say to expose them for 10 min but the last time i got a real shitty result because my ink was not very thick. Im thinking maybe 5 min would have been better.

@Tab54o

Yes, is MG chemical (ordered from Digikey) PCB. 5 minutes worked good for me, recommend test on tiny piece....let know if works for you..Aloha, UC

@UnderseaCaveman Ill be trying again this weekend on a double sided board. I need this one to come out good. The exposure time probably isnt as important as the contrast of the transparency. But we shall see.

[UnderseaCaveman]

@Tab54o Yes, the contrast is important, more specifically, were you have black ink you want to blocking light. However, I did it with a single transparency (not double as some others suggest on YT). Bottom line, ink will block an overwhelming majority of the light...think in 5 minutes of exposure thru transparency maybe your blacked out part is getting the equivalent of a tenthofsecond....big whoop, it won't develop and get etched off. Good luck to you, Aloha.

Toner transfer is perfect IF you do it properly. Don't bother with a clothes iron, get a laminator set to the precise temperature (170°C is what I use) - I used the design from Ultrakeet (Google it)

0.4mm clearance and 0.3mm tracks come out perfect for me.

@Tda7000 great tip, I checked it out....looks very interesting
