    Sensor for Weller LR21 needed...

    Hi! I wonder if anybody has faulty Weller LR21 soldering iron, but with working sensor (22 Ohm), and if he/she are willing to give it away ;), please let me know! The new one costs $$€€$$!!! TIA!

    Help needed desperately with DS2711 - NiMH Batt.Charger IC !

    Hi everybody, and Merry Christmas! Has anyone made ​​a battery charger with DS2711 chip? If so, please, tell me: 1) I intend to make a parallel circuit as in page#7 of datasheet (see attachment) - what transistors can I use instead of FCX718 - I prefer non-SMD transistors that can handle, say...

    Ordinary carbon paper instead of TRF Green

    Thanks for fast replies! @gogo2520: As I said I found this on site http://www.solidfluid.co.uk/sfsite.php/0000027F . I contacted Mr.Andy from SolidFluid and you can see what he answered to me in attached TXT file! I did not want to discourage you about the use of carbon paper - maybe my carbon...

    Ordinary carbon paper instead of TRF Green

    Well, I tried to use carbon paper, but to no avail. I just got a lot of mess. The dye from CP is spilled all over the PCB. I had a lot to clean with a toothbrush and detergent to remove CP pigment from it! I have no idea is some of pigment remained on toner. In attached image you can see final...

    Ordinary carbon paper instead of TRF Green

    Yes, I agree that paper residue isn't a problem... It is only important when applied TRF (or, maybe, carbon paper) - then it must be pure toner on board. gogo2520 has problems with applying TRF White - TRF does not work except with clear toner...

    Ordinary carbon paper instead of TRF Green

    Ok, I will not give up - after all some PCBs have turned out quite well... @gogo2520: If you are using magazine paper you will always have white residues of paper, and white TRF certainly won't stick to PCB! I use gummed paper for this (it's much cheaper than Pulsar's) - dextrin coating...

    Ordinary carbon paper instead of TRF Green

    Thank you all for your answers! I found it on http://www.solidfluid.co.uk/sfsite.php/0000027F The reason I ask this is because I can't get a uniform results: sometimes is pitting minimal with one sort of magazine paper, sometimes is PCB unusable... (I always use laminator with same settings).

    Ordinary carbon paper instead of TRF Green

    Hi, I'm interested if anyone tried to use ordinary carbon paper instead of the much more expensive Pulsar TRF Green? THX!
