First PCB in 25 years :-) - Diptrace and PCB Fab in a Box

(1/5) > >>

kaz911:
okay - just etched my first PCB in about 25 years.

Layout done in DIPTrace and printed on HP LJ on PCBFab in a box transfer paper.

Then rolled through a laminator

then etched.

I was supposed to use a "green top coat" on top of the printer etch - which would fuse it the layers a bit better - but every time I tried - it pulled of some of the tracks.

I tried printing on a new LJ 2055dn which is 1200 dpi - but that did not work - the toner is so pitted that... yes... not working. But the tiny HP 1102 worked okay. Im still not perfectly happy - and first etch will go in a frame and not be used.. since there are a few broken tracks where the FeCl was faster than I was - so they are broken. But it looks "reasonable" I think for attempt no 1 :-). But after 25 years there are SO many things you have forgotten. :-)

T4P:
Thanks for sharing !  :)
I now use a Epson CX17NF which is a LED printer and according to epson it uses very small particles .
Hmm .
Must try .

kaz911:
Fine Toner on the LJ 2055dn caused a lot of problems - the black was not "thick" enough. Just try to print a solid black box on a white sheet and see if you get a uniform black - or a black the varies a bit in color (so lighter black some places and darker black other places)

EU1:
Just use hatch pattern for ground plane.

kaz911:
it was not the ground planes that gave the big problems. It was pitting inside the tracks. (tried printing with and without ground planes)
