2013-12-15 00:33 or maybe you're not ironing long enough 2013-12-15 00:33 or not applying enough pressure. you can pretty much push down as hard as you like.. 2013-12-15 00:34 also, what does "doesn't want to stick" mean ? nothing at all ? 2013-12-15 00:37 i meant the toner doesn't want to stick completely on the board :) 2013-12-15 00:38 i set the iron to the ma 2013-12-15 00:38 *max 2013-12-15 00:38 if i still see the toner still stick to the paper does that mean that not enough heat being transferred ? 2013-12-15 00:38 in terms of pressure my feeling is i apply enough pressure but probably need to press bit harder 2013-12-15 00:40 yes, i'd try with a bit more pressure and maybe more time ironing 2013-12-15 00:41 how do you treat the surface of the paper ? do you clean it with alcohol ? or not at all ? you can try reversing whatever you do there 2013-12-15 00:43 (clean with alcohol) wet a bit with alcohol, leave it there for a few seconds, then gently remove the jelly-like stuff from the surface with a paper towel. 2013-12-15 00:43 not all papers have such a surface treatment, but many do 2013-12-15 00:55 for the paper not at all no treatment 2013-12-15 00:55 you mean clean the paper with alcohol before printing or after printing the artwork ? 2013-12-15 01:01 mldr has joined #qi-hardware 2013-12-15 01:01 before printing 2013-12-15 01:05 jekhor has quit [Read error: Operation timed out] 2013-12-15 01:11 this the current one I'm working on ..... http://snag.gy/hWEBO.jpg .... http://ctrlv.in/270531 .... http://ctrlv.in/270532 2013-12-15 01:11 i'm still soaking the board in the water with hot water..let's see if those paper will come off by itself 2013-12-15 01:13 don't soak. the paper really ought to come off dry. 2013-12-15 01:13 if you soak it, you weaken the bonding of the surface, so the paper is more likely to remain 2013-12-15 01:15 i wonder whether the copper is smooth enough. you're using fine steel wool, right ? not the coarse stuff 2013-12-15 01:16 fine = the threads are about as thick as hair; coarse = the "threads" are maybe 0.5-1 mm wide 2013-12-15 01:17 then, you should scrub in an X pattern: left-right until the copper shines, then up-down until you only see up-down grooves, then maybe repeat left-right 2013-12-15 01:18 then clean the board surface with alcohol and paper towel. this is important for removing the steel dust 2013-12-15 01:25 i think the step that i'm missing in cleaning the board is the use of alchohol....i only use water 2013-12-15 01:27 ah no, water is bad. that'll only help the oxides back on board 2013-12-15 01:28 besides, the alcohol will get rid of any lipids 2013-12-15 01:28 i'm uploading the steel wool pic 2013-12-15 01:29 http://ctrlv.in/270542 -- steel woll 2013-12-15 01:29 that's the coarse stuff 2013-12-15 01:29 another batch trying again -- http://ctrlv.in/270543 2013-12-15 01:31 hmm, that paper looks quite thin. maybe that's part of the problem 2013-12-15 01:33 the one i use is about 240 um. for comparison, regular laser printer paper is about 100 um. 2013-12-15 01:34 so the printer paper has about the thickness of the paper you put photo prints on 2013-12-15 01:35 well, maybe it only looks thin. how large is that sheet ? 2013-12-15 01:36 if i compare with a normal A4 paper it's bit thicker 2013-12-15 01:36 the steel wool you want should look like this: http://en.wikipedia.org/wiki/File:Steel-wool.jpg 2013-12-15 01:37 or like this: http://d3rhfm7sshutfw.cloudfront.net/wp-content/uploads/steelwool-300x285.jpg 2013-12-15 01:40 that other steel wool, if you pick the copper/bronce version of the same structure, makes an excellent sponge to clean the soldering iron. much more convenient than real sponges since it doesn't need to be wet. 2013-12-15 01:40 the result after peeling off from the board (this is the 2nd attempt) -- http://ctrlv.in/270546 2013-12-15 01:40 (but don't use steel wool - use copper/bronce wool. the steel would damage the tip of the soldering iron) 2013-12-15 01:41 (picture) i'm confused :) 2013-12-15 01:42 what's that yellow-white film stuff ? 2013-12-15 01:42 this is the result on the board (for the 2nd attempt) http://ctrlv.in/270547 .. and this is the result on the paper what is left over of the toner after peeling it off from the board http://ctrlv.in/270546 2013-12-15 01:42 the "yellow-film" stuff is a brochure paper i'm using 2013-12-15 01:43 ah, i see 2013-12-15 01:43 you still have the problem that the paper disintegrates 2013-12-15 01:44 that paper probably doesn't have enough strength. and it probably simply doesn't have enough plastic/jelly on its surface 2013-12-15 01:44 so the toner really likes to stay on the paper 2013-12-15 01:45 please use a glossy "photo" paper for ink printers. once you get that to work, you can always try to find some cheaper paper source. but it's probably not worth the effort. 2013-12-15 01:46 this is the original brochure paper i used for the 2nd attempt http://ctrlv.in/270549 2013-12-15 01:47 ah, i see. don't know how these are made. the chemistry may be quite different from "photo" paper 2013-12-15 01:48 looks like i need to revisit (1) the way the copper is being clean and (2) just use photo paper ... what you think ? 2013-12-15 01:48 btw, there's yet another choice: if you can't find any photo paper with enough plastic on it, you can try the plastified paper on which adhesive stickers come 2013-12-15 01:49 (1) for cleaning the copper .. will need to find the steel wool you showed in that link and also will need alcohol...in terms of cleaning the board...i just use alchohol to clean it OR clean it first with water and than apply alcohol > 2013-12-15 01:50 a few warnings about that, though: a) you need to clean it very well or you'll drag glue into your printer causing an early retirement of at least the transfer drum, and b) you need to work at a lower temperature with this sort of paper 2013-12-15 01:51 "lower temp with this sort of paper"...you mean the photo paper ? 2013-12-15 01:51 (cleaning) just alcohol: 1) scrub it nice and shiny with the steel wool, then 2) put a bit of alcohol on it, wet a paper town with alcohol, then rub off the steel dust (you can apply a good amount of pressure). you'll see that the paper towel comes back black. 2013-12-15 01:52 (lower temp) subtrate for adhesives. the "plan B" approach 2013-12-15 01:53 but it's better if you can get "photo" paper to work. that's more robust. the adhesives stuff is also very sensitive to pressure and such. so it smears easily. you can get it to work but it takes some effort. 2013-12-15 01:54 it's basically the exact opposite of your not-to-cooperative brochure. but of course, if failure lurks at one extreme, that doens't mean that the other extreme is any friendlier :) 2013-12-15 01:55 # s/-to-/-so-/ 2013-12-15 01:56 this is the photo paper i got ... http://ctrlv.in/270552 2013-12-15 01:58 the one i used was called "HP Premium Plus Photo Paper" 2013-12-15 01:58 actually, "HP Premium Photo Paper, glossy" 2013-12-15 01:59 so maybe that's one extra ppm of plastic :) 2013-12-15 01:59 is this Isopropyl Alcohol http://www.recochem.com.au/files/downloads/Cons_Isopropyl_Alcohol_PDS_Oct11.pdf enough ? 2013-12-15 01:59 but of course we don't get that good stuff around here anymore 2013-12-15 02:00 the replacement i use now is this: http://yidugroup.en.made-in-china.com/productimage/jesJuzASYmGk-2f1j00FeOaLPRSgTUo/China-Glossy-Inkjet-Photo-Paper.html 2013-12-15 02:01 it gives off particles that will eventually produce visible artefacts on the printer's drum but the transfer is very clean. and no problems at all with paper disintegrating. 2013-12-15 02:02 dos1 has quit [Ping timeout: 248 seconds] 2013-12-15 02:03 (alcohol) looks decent enough. they don't even mention the concentration so maybe it's actually pure :) 2013-12-15 02:05 (alchohol) will buy that later today and also the steel wool and will try again with the HP photo paper again 2013-12-15 02:05 using this paper http://yidugroup.en.made-in-china.com/productimage/jesJuzASYmGk-2f1j00FeOaLPRSgTUo/China-Glossy-Inkjet-Photo-Paper.html were you able to do transfer completely everytime ? 2013-12-15 02:06 if you have a stationary / computer supplies shop on the way, maybe look for that chinese paper, too. maybe you're lucky :) 2013-12-15 02:06 yes, it works great. remember this ? http://downloads.qi-hardware.com/people/werner/tmp/paper/ 2013-12-15 02:07 the one on the left is the "HP Premium Photo Paper, glossy", the one on the right the paper from china 2013-12-15 02:07 there is on ebay.com.au http://www.ebay.com.au/itm/New-20-Sheets-x-A4-Glossy-Photo-Paper-For-Inkjet-Printer-140gsm-/251249784571?pt=AU_Computers_Printer_Accessories&hash=item3a7fa776fb 2013-12-15 02:08 its main weakness are large surfaces. there, it sometimes leaves holes. but then you can just cover them up with a permanent marker. or ignore the imperfection. 2013-12-15 02:09 Markvilla has joined #qi-hardware 2013-12-15 02:10 mine is heavier, 240-260 g 2013-12-15 02:10 when you did this http://downloads.qi-hardware.com/people/werner/tmp/paper/ you just peel the paper off and that's it ? 2013-12-15 02:11 yup. nice and easy ;-) 2013-12-15 02:11 the one that I have http://ctrlv.in/270552 it says 250 2013-12-15 02:12 well, i wash the board afterwards. with tap water, rubbing it with a thumb. that way, any plastic residues that may get in the way of the acid come off. else you can have some small copper spots. 2013-12-15 02:13 250 sounds good. that means that they have enough space to make it nice 2013-12-15 02:15 i was wondering you know with this one http://ctrlv.in/270531 what will happen if the paper is not removed completely and then etch it ? 2013-12-15 02:16 the acid will politely refrain from touching the areas it's being blocked from 2013-12-15 02:17 i see....because it looks like it sticks to the copper but the paper "refuses" to let it go 2013-12-15 02:17 maybe a little bit will make it under the paper but its effect will be greatly reduced 2013-12-15 02:19 well, unless you make a REALLY aggressive mix. if you make the acid bad enough, then it'll just eat through anything in its way. be that paper, pieces of nick, or whatever :) 2013-12-15 02:20 yup, that's what it looks like. most likely the thin plastic surface coating, not the paper itself. so that's a very efficient acid barrier. 2013-12-15 02:20 from all the paper i've tried that one i notice was the most successful one....but it's so annoying that i can't get rid of the left over paper 2013-12-15 02:21 http://ctrlv.in/270531 --> in this one you notice the top and bottom part i strip off the paper and the whole toner came off with it 2013-12-15 02:21 naw, that doesn't look very successful. exactly because of that problem 2013-12-15 02:21 don't be fooled by the nice print you can see through the paper. that's toner on paper, not toner on copper. 2013-12-15 02:22 ahh ok...thought that the toner has "stick" to the copper but the paper refuses to do it 2013-12-15 02:23 all the places where you were able to remove the paper say otherwise :) 2013-12-15 02:24 well, except the about 2 x 2 mm lower right corner. these three vias and their traces look quite nice ;) 2013-12-15 02:25 will try again later .. need to go out after this and drop by to buy the alcohol and steel wolll 2013-12-15 02:25 happy hunting ! :) 2013-12-15 02:32 oh the other thing i was thinking and tried was the clear tape https://www.google.com.au/search?q=clear+tape&client=ubuntu&hs=URi&channel=fs&tbm=isch&tbo=u&source=univ&sa=X&ei=qBStUtoziMiVBZyLgNAG&ved=0CEEQsAQ&biw=1615&bih=960 2013-12-15 02:33 what about it ? 2013-12-15 02:33 so i lay a brochure paper and put clear tape on top of that and than print on it ..and after ironing the board i peel it off i can see that is sticks better to the board 2013-12-15 02:33 ;-) 2013-12-15 02:33 but it was not 100%..it was around 70-75% successful on the board 2013-12-15 02:33 well, that's one way of getting plastic ... 2013-12-15 02:34 yes, that could work if you refine the process sufficiently 2013-12-15 02:34 do you think the paper that is used for laying the plastic tape on really matter when it comes to ironing it to the board ? 2013-12-15 02:36 will try that again once i clean the board properly and see if it will work 2013-12-15 02:37 (paper used for laying the plastic tape on) you mean if you print on adhesive tape instead of on photo paper ? well, it would still have to make a firm connection with the adhesive tape. but else, it would be removed from the equation. 2013-12-15 02:45 kristian1aul has quit [Quit: Reconnecting] 2013-12-15 02:45 kristianpaul has joined #qi-hardware 2013-12-15 02:45 kristianpaul has joined #qi-hardware 2013-12-15 02:46 panda|w530 has joined #qi-hardware 2013-12-15 03:06 bwahaha: http://www.indiegogo.com/projects/iteaduino-lite-most-inexpensive-full-sized-arduino-derivative-board 2013-12-15 03:06 finally - an arduino at the price of a four-pack of toilet paper. 2013-12-15 03:14 panda|w530 has quit [Ping timeout: 264 seconds] 2013-12-15 03:15 Markvilla has quit [Quit: ["Textual IRC Client: www.textualapp.com"]] 2013-12-15 06:26 wolfspraul has quit [Ping timeout: 252 seconds] 2013-12-15 06:28 wolfspraul has joined #qi-hardware 2013-12-15 06:37 kyak_ is now known as kyak 2013-12-15 06:46 wej has quit [Ping timeout: 245 seconds] 2013-12-15 06:48 wej has joined #qi-hardware 2013-12-15 07:00 FDCX has quit [Remote host closed the connection] 2013-12-15 07:01 porchaso0 has quit [Ping timeout: 246 seconds] 2013-12-15 07:02 huh.
