Re: [Homebrew_PCBs] Re: EDDING 404 ETCH TEST WORKS GREAT

 


This is a web site that explains quite a lot of what I posted. I do not have th Apache
Lam but have a Scotch brand Lam that is  not hot enough but between that less expensive Lam and my house hold clothes iron I get the job done and traces are protected real good thru acid bath. I use Datka version of positive developement
Coated Copper Clad Boards | MPJA.COM bought here and the Gree TRF sticks real good plus this board etches fast an is a quality Board solution.

Lam Model # TL902 recomended on U-Tube video, Should have tried GBC model instead thou as a after thought due to temperature of exiting board. It handles 1/16 in board thou.

[Homebrew_PCBs] Re: EDDING 404 ETCH TEST WORKS GREAT available in bottles... WHY SHARPIE FAILs

 

YES I did find EDDING 404 refill ink was sold by the bottle.

Noting that the STAEDTLER lumocolor permanent pen 313 black worked well for me
I chased down STAEDTLER 313  refill ink and I am waiting to see what that behaves like in a
drafting .5mm technical pin when the ink arrives from germany.

So it seems that EDDING and STAEDTLER offer refill ink while SHARPIE does not.
 
On the topic of inks......
I have figured out what fails for me with using SHARPIE permanent markers.
Considering that I have used all types of tip sizes and colors.... red blue green.. gold,,,,silver....
and permanent and high temp industrial...... everything with SHARPIE PERMANENT maker written on it......
AND THEY ALL FAIL me in the same way.

I used them for touchup on black HP toner that has been transfered to PCB via heat pressing.
99% of the traces do transfer quite well but once in a while I get a gap or a pinhole.
http://www.learnmorsecode.com/pic/line/index.html

so I have taken up the standard practice of simply tracing over the toner with a permanent black marker
to reinforce the toner traces with ink.
BUT
THIS IS WHERE THE SHARPIE FAILs because the chemicals in the SHARPIE actually melts toner that
STICKS to the sharpie tip and clogs it to the point where is no longer flows ink.
I thought my sharpie TIPs were drying out but no...... still plenty of ink,,, just blocked from flowing off the tip of the
sharpie where I had been tracing toner.
NO SHARPIE MARKER HAS PASSED THIS TEST for me here yet.

So far it seems that this clogging action does not happen with EDDING 404 or STAEDTLER 313 markers.

Hi all,

I found out that the ink used is EDDING 404 is also available in bottles, printer cartridges an even spray cans.

This could be interesting for people who have altered a printer to print direct to PCB copper clad.

Just Google EDDING 404 ink and you find what I found. As up till now I did not find any prices yet...
So if someone wants to search deeper and let us all know?

Assume I am totally clueless and write that email again with links to explanations of what you said. Please.
I am assuming Green TRF is sold by pulser?
but not sure what positive development
or
cheap scotch lam means.

and what is a cheep household iron used for when the laminator is already the perfect heat and pressure?!??

If you have not tried Green TRF of pulsar  type yet you should. It protects thru acid bath
when doing toner transfer and  positive development real good even with a cheep scotch lam followed by a cheep household iron.

[Homebrew_PCBs] EDDING 404 ETCH TEST WORKS GREAT

 

I don't know who recommended EDDING 404 markers but I must say thank you for the suggestion.
The EDDING 404 most definitely can draw SOIC pads and do toner transfer repairs.

So I would conclude that EDDING 404 is by far my first choice for an acid resist pen now.


I always grab some stray pens..and this time a crayon... to check for acid resistance.
BIC INTENSITY FINE 
and
LA PEN
both just washed right off the copper.

Crayon barely worked.... and crudded up the acid bath.
