kad Quad Crasher | Try Press-n-peel. Same basic method, but made for the process, releases toner easily and peels off easily. http://www.techniks.com/how_to.htm -K |

I use the "cheap photo paper" method myself. Similar to what you've been doing, but use cheap (NOT waterproof) inkjet photo paper, running it though a laser printer. It's a bit harder to get off (you soak it off after ironing) but produces a cleaner line than magazine paper. Example: http://behindthetone.com/johnfisher/transfer/trans.htm -K |

jakestew Registered User | Wow spog, that seems like a lot more work. You can just draw the lines on with a sharpie marker. I can't imagine painting them on. Press-n-peel blue works OK, but I don't really think it's worth the money. You can use water-soluable paper (dissolvo is one brand) if you want to do the water method. Otherwise try parchment paper. You can find it in the grocery store, it's used to line baking sheets. It's usually called parchment paper or grease proof paper. Cute store girls can usually help you find it. |

slebetman Registered User | I second the photo paper method. It's my go-to method of etching PCBs. But you may need to try out several different brands of photo paper before finding the one that works best. They all work, but some better than others. As with most things manual, you need lots of practice before perfecting the ironing bit. Took me a while to figure out how much pressure at what temperature for how long to apply the iron to get the ink on just right. I've never tried magazine paper but in my experience photo paper can be tacked onto the copper. Just iron on some ink on one corner (I sometimes deliberately draw guide marks or logos for this purpose). As you iron the sheet it will stick to the board so you only need to worry about alignment at the beginning of the process. The down side is that the paper sticks to the board so you can't just peel it off and check your work. |

abenn Registered User | I don't have a laser printer, so press'n'peel and other similar transfer methods seemed to be out. I found I can get excellent results using my HP inkjet printer to print the pattern on transparent vinyl in yellow ink for photo-printing. I made my light box from 90 uv leds for about £5 -- it runs off a 5S A123 battery but, depending on your led layout, could run off other voltages. The only other thing you need, apart from the normal etching fluid, is universal developer, to develop the "print" on the copper board after exposure. So, the "extra" running costs are photo-resist board instead of simple copper-clad board, developer, and transparency. |

jakestew Registered User | Don't overcomplicate things. Simple parchment or magazine paper works perfectly. If you want to spend more money on the same process then get dissolvo or press-n-peel blue or white. Fooling around with UV, print shops, or photo paper just isn't worth it. This isn't rocket science, you're just transferring laser toner to a copper board. |

RC Bogan Modeller, NOT unboxer | My prefered method is to use glossy photo paper, I did try glossy magazine paper but the laser printer made it puff up with air bubbles in it and it smelled bad. There is a trick to using glossy photo paper, after ironing it on your board soak it in warm water for 5 min+ then try to separate the layers of paper, then use your finger and rub the paper off (it comes off in balls under your finger when you rub). I use Ferric Chloride at room temperature 20-25°C and never had a problem. Cheers |
