Did anyone at Metalab try cutting PCBs on our vinyl cutter? See http://www.kobakant.at/DIY/?p=1132 Best, Esad

If someone is going to try this: go ahead, BUT please buy your own plotter-knife and don't use the one provided by metalab. cutting through (even thin layers) of metal will dramatically reduce the blade's lifetime. if needed, I can help anyone by pointing out where and which knife. adrian

I tried something similar: I used vinyl as a mask for etching. It worked (I even used this method for a QSOP-chip breakout board), but the quality was limited. The thickness of the traces was varying (+/- 0.3mm, maybe more) and I had to do a lot of repairing work with a precision knife. You might get better results if you only use curves instead of straight lines with quick turns, but as it's an accuracy problem I think it's unavoidable. Here are some photos: https://www.dropbox.com/sh/dmefmfn307do5cl/B9L2-fqkIT/100_0759.JPG https://www.dropbox.com/sh/dmefmfn307do5cl/rY5lPUlmkm/100_0799.JPG PS: As someone mentioned before: If you want to do that, get an other knife. Also make some photos of the results, I'd love to see them. -powertomato
As I have slight phobia of etching and strong acids in general, I think I'll give this a try :) @adrian: where do I get the right knife? Where would one get copper sheets? Esad

there is also the possibility to make etch a curcuit using the CNC, or so I've heard.
hej!

i am also afraid of strong acids, but successfully etched pcbs in the past. using precautions like protective eyewear, labcoats and gloves minimized the risk of injury. the approach with the vinylcutter seems to me like a no-good solution. besides placing the traces by hand on some carrier material you loose a lot of accuracy. the vinylcutter can not cut very fine lines. so this is no possible solution for TQFP packages or other small parts with tiny pads. and for all the other parts you can simply use lochrasterplatinen. they come in all forms and shapes, even for SMD components. also we have a rather large assortment of SMD breakoutboards in the bauteilsortiment. if you still want to give this a try please document your progress i would really like to see what comes out of this. :* -flo ps: i once tried to use the lasercutter + copperplate + black spraypaint to create a pcb .. it kind of worked but not so good.. i think its a question of the right combination of spraypaint and power on the lazzzor. of course with this method you then need the acid again.. i was reading about some conductive ink once on hackaday. pcb printer anyone?

knife: http://de.y-o-w.com/suchergebnisse/q?filter=true&FVkeyword=Schleppmesser+kle... if the copper sheet does not have a carrier foil, then you must use the big carrier-sheet (slightly sticky) stored under the machine - otherwise you will harm the machine and destroy your knife. the knife should only cut through the material, never through the carrier. conrad has only some infeasible small pieces: http://www.conrad.at/ce/de/product/529532/PB-Fastener-Selbstklebende-Kupferf... ad etching acids: I've worked with sodiumpersulfate for etching quite a lot a few years ago and it never did harm to my bare hands, if you wash it off after contact. it will however leave stains in you clothing, so wear a lab coat. adrian
