I use this method and it works great. I rough up the copper with 600 grit sandpaper to help the toner stick, polish with Comet and water to get off any grease and oxidation, then clean with acetone. I use Staples Photo Printer Paper which is nice and glossy. Its important not to touch the board after cleaning or the paper with your fingers since the oils on your fingers may prevent the toner from sticking. I use an older model GBC laminator and it takes about 6 to 8 passes for the toner to stick to a .062" thick board. My rule of thumb is keep sending it through until the PCB edges are almost too hot to handle. Etch by saturating a small sponge with ferric chloride. Wipe the sponge over the copper until the ferric choride gets very black, squeeze it out and saturate again. 1oz copper etches in 3-5 minutes with this technique with very little undercutting and it uses very little ferric chloride. Quality of the PCB is very close to photo etched and you can make a board from start to finish in 30 minutes with a bit of practice. Use gloves and ventilate well of course! Great vid!
Dude! Wear gloves when handling acetone! Solvents will do a number on your skin. My hands are permanently chapped/cracked/bleeding (even with applying lotion religiously) after handling solvents and degreasers without gloves over ten years ago.
Try turmeric a fresh living turmeric and apply to your skin hopefully it will heal permanently -- there is some good nutrients in the turmeric for human body
Hi buddy!, what size of maximum thru-put thickness has this laminator?.The GBC-H220 one, is 1mm.The copper board has more than this.Can we damage it or not?.Most of this machines come with microns format.
no I didnt' modify the height of the rollers. The roller coating is smooth enough to deform. At least for regular PCB thickness. The one on the video is 1.6mm width (I have just measured with my caliper)

at 1:04 he is done cleaning the pcb
Yes sure it's a very regular paper. The kind you can find in cheap glossy magazines (with very thin pages looking expensive !)

Yes you are right
thank you for this wise advice

How long did you leave it in the water?

i like this video.
what do the resulting etches look like? any bleed?
What is your PCB thickness? Did you modify the height of the rollers for the PCB thickness 1.6mm?

@@freedom2000 Perfect!
3 to 4 passes are enough...peraphs 1 wuld be enouh also, but I am used to pass 4 times !
To remove the paper only a few seconds (30s) are enough
what the maximum thickness this machine can take
for best finish is better to pass the pcb into laminator 20 times and in all directions angle 45, 90 y 180 for improve results.

No that's not needed. Two or three times is far enough
This video is recommended to me after 12 years
It's a good recommendation 😂
This is the quietest house which I heard. ;-)
chrisfxwolf
I asked for it :-)
180mm fans...try them
THank you Abraham
I don't were well
photo fab is where its at
sorry I don't understand your comment. Please explain
riston acid resist. uv exposure.
my process doesn't need UV exposure
@@johnw1385 you need a lot more equipment to do it right.
I very like this excalent video.
Hi,
They look perfect down to 0,1mm tracks and inter tracks
Have a look to my web site freedom2000.free.fr/PCB_index_eng.html
