on scanner glass is only thing I can figure as I looked at all the traces before tinning with liquid tin.
here are some photos of completed boards(not easy taking pics)same boards as posted earlier just tinned.
as well as boards before adding components.
We pretty much gave up on the wax paper idea.What got my attention was the original concept of using wax paper. I like the concept, but I also found it disturbing because of the thought of the wax coming off onto my printer fuser. Has anyone seen any negatives doing this?
They are part of the Pulsar commercial product.What are the foils you guys are referring to?
Direct to PCB inkjet looks really promising, but it's still a little more work than I'd rather do. The resolution is seriously nice, though.It is amusing how many people still try to use ink jets for toner transfer. Now if I was to use ink jet technology it would be to make organic transistors and LEDs as a home brewed not quite chip technology (just a dream).
I have nothing to do with the Glue Paper. That's Rolf.
I think the pittng your talking about has to do with the fact that you need to seal the toner with the green foils, not the white.
It is wrong to think that you have achieved the best possible or even reasonable result with the toner system when you failed to follow directions.
As I recall you used a color printer. No one does that and I am quite sure the instructions call for b/w.
The chip is the TI chip recently used in a post by Mark. The lines are all 10 mils and as so many claim here it is easily done with the TTS. So lets do that and post their results. Include the type of printer used and lets see what happens.
Well, I've already posted mine, and it looks pretty good. I don't have any pinholing, a bit of rash on ground planes, but not on the traces themselves. I only get this rash when using the new muriatic acid/peroxide etchant. With ferric chloride I don't get any rash unless I've done something wrong.
Hi Mark,
Your boards do look great. Do you use Puslar's green foil? If not and if you are using something else could you explain what that is. My issue is the wax and or oils that are on the surface of my laser prints. I now have something new which is the photo based system which I was using some 25 years ago. I am thrilled this is back because I was good at it then and like riding a bike it gets going fast when you begin again. I also am thrilled because I can make my own negatives for pennies where before I was paying $10 for photo negatives and those had to be perfect otherwise its another $10. That was why I gave up waiting for some new technology to come along. It has and works great!
Just looking at Youtube videos, this Make video is almost my exact process, with the same paper I use. Mine is the older paper in the old packaging, though.
