Hi guys, From this ground I have learned about toner transfer and PCB making and have been doing it for a couple of years now. Recently, I have been starting...
... With toner transfer, 10/10 is quite easy. I've made my own board for a 0.4mm pitch LQFP-80 package, which will be something like 8/8. The biggest problem I...
I have found that a sponge, or piece of foam rubber, will take those off easily. The foam rubber is soft enough not to damage the traces, and you can rub quite...
I've gotten down to 8.33 mil with TT with a fair degree of reliability. 6.66 I can do if I'm careful and put extra copies of the board on the print - there's...
Thanks guys, that gives me a bit of confidence to give it a go with toner transfer. I also checked into various forms of photoresist and it turns out that it...
I'm most curious if anyone has experience with toner transfer and spray etchers. Will the toner hold up to the etchant spray? I'd even send a board with a...
Has anyone tried attaching a very fine pen to a cnc then etch the pcb board? Right now I'm using pcb-gcode but it's a pain because it takes so long to remove...
... I have not tried it but the pen should have some kind of spring pushing it into the PCB at a constant pressure rather than ridgedly mounted.. Cecil K5NWA ...
... Can you use the CNC to remove the 'border' of the tracks instead of the majority of the copper? We achieve this by making the majority of the board a...
Yes, in fact it has been done usually using plotters. Look in the Links, Photos, and Files sections of the group here. Some have reported issues with the pen...
I have tried this. Not using PcbGcode, since I use DeskCNC. I output a dxf file from DipTrace. Input the .dxf file into DeskCNC. Use the pocket command to...
I'd try Rapidograph pens http://www.dickblick.com/zz210/03/ If I remember right they are basically a hollow tube with a wire in them. The wire actuates a ...
Seems like a pen might not be ideal. What about an inkjet head attached to a cnc? The reason for the CNC is that I already have a CNC with .0001" repeatable...
I've even tried those carbide tip cross groove plotter pens (basically what was said to be the best). It didn't work either, the trailing edge scratched too...
I have done some various experiments with engraving (isolation milling) or plotting of resist lines using CNC machines. I do not feel this is a good approach,...
... A gentleman named Fogassa is building a 3D printer using a Lexmark. He is not using the printer electronics to run the head, he's using his own drivers and...
Hi all someone from the group suggested I join and tell you all about my Lexmark 25 hack. I read the epsom hack somwhere on the net but didn't want to have to...
Hi PCBers, Mostly lurking, but thought I'd comment on this thread. Have U ever heard of MicroPen? I used to work with their equipment about 10yrs ago. I was...
What is wrong with sharing it here? I'm sure a lot of us would like to hear about this. Steve Greenfield ... "carbon ... lines ... (?) ... between ... color ...
Hi guys, I have been using Ferric Chloride for a few years now - works fine and is easy to get and dispose of when spent. The downside is the mess. I know...
A minimally maintained CuCl etchant works well for me, right next to machinery and tools. The etchant container is covered, and i also put an upside down...
Which looks remarkably like the Micropen that Tony referred to. http://www.micropen.com/ Not to be confused with the Cross Micropen nor with PDA styluses. ;') ...
