Toner Transfer Is No Fun
Friday, March 6th, 2009Toner Transfer
As part of the process for home printed circuit board etching, you need to somehow get a resist where you want there to be copper. After the transfer, you can then apply any of many different etching chemicals which then dissolve the unprotected metal. In my opinion, this step, good toner transfer, is the hardest and biggest roadblock to anyone trying to make a quick board. The concept is relatively simple, iron a laser printed piece of paper onto the copper, fusing the plastic toner to the copper. Commercial products are sold that achieve this much easier, but who wants to have to spend money, pay shipping, then wait for it to arrive? So, trying as many different tutorials I could find on the Internet, I set out to meld plastic to metal. I used a cheap old LaserJet 5P for this purpose, and printed a schematic out on magazine paper first. I ironed it on, and it partially held, as visible in the lower left corner of the photo. I then used Office Depot Presentation Paper to try and get a better stick. It was a bit better, as seen in the upper right. I also tried different combinations of scrubbing preparations and such on the back. None fully worked. I got a bubble tank ready, a bubbler, all the chemicals, and even a glove box, and the only conclusion I can come to is this: toner transfer is no fun!



Yep, you’ve probably seen the commercials for them. And yes, they seem cool, that is, if they actually work. And if they do, how well? Honestly, have you ever seen anyone using one? Anyways, I seek to prove the practical usability on the stains they claim it works on, and even the ones they claim it doesn’t! It’s meager list of things it specifically says it doesn’t work on are ink, blood, and grease. Who knew it would be my top three shirt-killers? None the less, a review with lots of pretty photos is up soon!
