Chris, I only started to use this method last week, when I ran out of photo resist board. I have made about ten boards now with 2 failures which was due to the...
... I shorted the switch out on my laminator as a quick and dirty test. The next thing that happened was the over temp. fuse blowing! I noted also that the...
On Thu, 01 Feb 2007 13:46:30 +0100, Barry Hitchen ... Hey, good to hear someone else is using verbatim paper. Which is yours, is there any number or weight or...
Ok I am seeing the same problem with this 'working' paper as my other papers, and now I'm on a laminator, not an iron.... My problem is when I heat the...
... I see something similar with my paper, it tends to rip off the board outline if i do not draw a second, wide, outline around it to anchor the paper to the...
... I'm sure it not the paper, got to be the copper, but I cant see why only a few of us (well 2!) seem to see this. Unless its more noticeable with some...
... Sure does, but paper seems to expand or contract much more. Try it. The expansion coefficient of copper is mostly irrelevant because the PCB is much...
Just noticed maplin now sell sodium persulphate and fecl......... I've never heard of sodium persulphate before, I dont read all the posts, just mainly the TT...
Ok I have had enough tonight of TT I need to get 10 little 2 inch * 2 1/2 inch boards done. (only holds a pic and some transistors) I can buy the developer for...
Anyone any comments on the UV lamps on ebay for drying nail varnish? seach on ebay with "UV nail lamp" Or what about those CCFL lights to put inside the PC...
The exposure is fairly critical, especially if your film doesn't have very high contrast. You can use sunlight but it is very hit-and miss. You need bright...
I don't see why one of those nail lamps wouldn't work for small boards. You do need some method of holding the film firmly against the board. Any gap between...
... I've noticed they also sell replacement bulbs, much cheaper than the real type of bulb, in a pack of 4. I may try sunlight first, I only need to make 2...
... Just another board material, the copper is still on the outside. You can see descriptions here: <http://www.felsweb.com/lam_faq.htm#B> There was also a...
... Mercury vapor bulbs will work the best and give the fastest exposure. Another way is to get a cheap 500 watt quartz halogen work lamp and use it for UV...
I have a few questions about the mis-pro direct inkjet printing method. I saw it mentioned that the durabrite inks may soften during etching, is the same true...
... 30 years or so ago I made a BUNCH prototype boards both at home and at work using #2 photofloods (IIRC 300W). A sheet of plate glass to hold the film in ...
... Hi Lez, I used to do photo all the time. It's easy once you get the times down. I used the positve board stock as the process is easier and the results...
Don't bother with UK sunshine - unless you only want to make boards for a few minutes on one morning a year. Its far too unpredictable: your tests, and your...
Hi I have given up on TT, so I am gonna try photo method. How do do the artwork(photo mask)? By that I mean what sort of transparency, printer etc? Jeri ... ...
... lol your right their. ... Now that seems a good idea, if 'standard' white tubes work, then all I need is some 'energy saving' lights, usually about 8 or 11...
... Actually thats a good question, I'd not given much thought to that, I only have about OHT sheets left, and those are for inkjet, and I'd sooner use the...
What sort of inkjet have you got? Epson Durabrite ink produces very good quality prints. For some reason red seems to work best. I find toner tends to end up a...
