Why not use Circuit Works conductive epoxy?

I don't know if you want this around if you have kids, but MG Chemicals makes "Liquid Tin" -- which plates in 5 minutes. The contents are nasty -- fluoroboric acid and stannous fluoroborate.

Hi all, To make spray-on prp resist work well, the copper has to be cleaned well. Some things that work: salt and vinegar, salt and lemon juice, citric acid, and probably lots of others. I like

The BLACKHOLE processes is fast, cheaper and safer to run than conventional electroless copper. This is expected since its aim is to replace the electroless copper line in the PCB fabrication plant.

Hey Adam maybe you should write a produre of your method of making PTH. I would love to know the costs involved and chemistry. I am not familar with the BLACKHOLE method. The hardest part is making

the whole holes

Check the Bookmarks area of Homebrew PCBs. A reminder for everyone- although the list hasn't been here that long, a lot of people have already asked and answered a lot of questions. I've posted some

Hello Dave, YES! There are some schematic and PCB programs out there. Eagle Express is a FREE download with ONLY a limitation of board size (4" x 3.2" size board) but it is FULLY functional

I need to draw some schematics of my circuits, but I do not have any software. Any recommendations on free or inexpensive software for this? The simpler the better. TIA, Dave The Inexpensive

I'm saving the file to Distiller from Ultiboard, not scanning it. I like the suggestion of using an HP G/L translator. The main thing I want to do is save the files so that I can upload them to

This link has a good description using conductive ink to actiavte the holes and then plate on that. http://www.thinktink.com/stack/volumes/volvi/pcbproto.htm I'm using eyelets. Recently I got some

I use 2 methods: 'Track Pins' made by Harwin (UK, I think). We used to get them from Arrow/Bell but I don't know if they still have them. These are a stick of tapered pins that you push into the

Distiller does have a resolution setting, but this may not help you. Distiller keeps vector objects in the PostScript as vector objects in the PDF. It has the ability to resample raster objects, so

Maybe you are using incorrect settings for Distiller? IIRC there was something about resolution (DPI). KPL

Other than using eyelets has anyone made Plated Thru Hole at Home and can give some tips?
