I fix the board in a vice and hold the drill perpendicular by eye, I don’t think

degrees, resulting in an error of 0.13 mm

My alignment is achieved through “patchlets” (thin “etchings” in the contact
sites, I think 20 mil, taking into account the spreading of the toner after the iron, will be suitable)
After transferring the toner it turns out fine on one side. At least
DB25 is inserted as into a “native” board.I had a problem with the “alignment” of the platforms on a double-sided one. The first problem
uneven registration when transferring toner, but I think this will be solved with
your technology. And the second problem is non-perpendicularity of drilling, solve
it is possible, IMXO, only with the help of a drill machine.
A drilling offset of 0.5 mm between layers has detrimental consequences for
fees. Of course, you can solder, but the “beauty” of the product leaves much to be desired.
I think that if you use a photoresist the result will not change :(

Of course, the hole doesn’t give a fuck - but a thin (0.5mm) drill may not give a fuck - it
it will simply break!... In order to somehow drill thin holes, you have to
Somehow sharpen the fragment and somehow drill it with it...
Hello fan

how is that?
Hello, lvd
Can anyone tell me the specific name of the paper from which everything was LOT?

Hello, acidrain
You wet the paper with acetone and wait for it to transfer. But the main thing here is not with acetone
overdo it and not underdo it %) The paper can be removed immediately.
By the way, who uses what to remove toner???

What printers are best to use? We only have HP1200 and HP1300 at work.

Not into acetone, but acetone onto paper. Otherwise everything will be blurry :D
Hello, CheburatoR

what does it weigh?
Hello, do_se
The question, of course, was not addressed to me, but I’ll try to enlighten you ;)
When you have drawn the diagram, do not make “CAM Processor”, but “Switch to board”...
And everything that is drawn on the diagram will be transferred to the board design.
If you use Eagle under a free license, you will receive a restriction on
the maximum board size, if I'm not mistaken, is 80x100mm, and the maximum number
layers - 2. Another feature of the free license (I have Igla 4.11R2
Light), then that during the initial distillation of the circuit onto the board, the elements are located
outside the board, and they need to be dragged hand-to-hand into the specified rectangle if
if you try to place elements “by”, an alert will pop up, like
"cannot perform action" ;)
Hello, do_se
do_> I looked at the main page of your site. I understand the technology
do_> making templates for LUT is as follows: first you draw a diagram in EAGLE
do_> then you export to Electra and breed there, then export
do_> (or are you printing???) in raster form....
I make a circuit and a board in Eagle but only provide power, then I ban there
where necessary on the tRestrict layer, I run PCB_To_DSN.ulp (comes with Electra)
I get the DSN file, export it to Electre, then export it back to Eagle,
I correct it manually, when it’s ready, I need to select the necessary layers and export BMP
- check the box monochrome, resolution 600dpi (depending on what resolution
at the printer), but I print from PhotoShop.
do_> I registered on Electra and am waiting for a letter with a link..... nothing yet
do_> the soap box was not found....

I downloaded it, looked at the demo, it’s a funny program. Demo board is installed
otogonal method with optimization. Apparently better than Eagle.
While I was tracing, the question arose: How do you place the components? Autoplacer with
Igla doesn’t seem to have optimization? I once saw on their website ULP, which is simply
"drags" components into the board...
Hello, CheburatoR

Have you tried managing the tracing parameters? Well, there is the number of VIAs, min.
width of tracks, etc. (please forgive me if this is a stupid question :))
Hello, do_se
do_> Apparently better than Eagle.....

probably not automatically :( although I tried a couple of programs, IMHO it’s not worth it,
In general, it is recommended to do everything manually, even tracing
Hello icebear

ice> VIAs, min. width of tracks, etc. (please call me if this is a stupid question :))
Well, of course I tried :) I tried to squeeze out everything I could, you can use the parameters in Electra
set both via ULP and DO file (you can read it in the description),
the number of VIAs is not generally set, it only indirectly depends on some
parameters. The quality of the tracing algorithm can be assessed by the number of VIAs. A
the width of the tracks can be set differently for each NetClass - the type for power supply is wider,
for thinner signals. Better read Eagle Tutorial and other smart ones first
Then if something is unclear, I can help you with books.
Hello, y-dmitry
ydm> What do you think of the DipTrace program?
I don’t care at all - I didn’t use it
Hello fan

fan> it’s hard to see him in the household. magicians...
We sell a special liquid for washing mounting guns.
It seems like the same acetone, only in a deodorant-type can.
Hello, y-dmitry
ydm> What do you think of the DipTrace program?
A program with a convenient, intuitive interface... everything is great, but
she breeds extremely suck.... this is the first program where I saw that
conductors run into each other when wiring... as seen when analyzing "on
eye" the problem is this: it lays tracks without being tied to the grid,
it turns out the following... draws two tracks at a distance of 5 mm then tries
stick another one between them, VIA does.... this is where sticking happens....
the tracer itself is also quite stupid... I manually, orthogonal wiring and then
I’ll do better.... by the way, with manual wiring there are the same problems with sticking...
Hello, CheburatoR
Che> It’s better to read Eagle Tutorial and other smart books first
Che> there will be something unclear, I can help.
Yes, I’ve been working with Eagle since version 3.xx :) Thanks for the suggestion.
Hello fan

Well, at least it smells like acetone :)
I can try (I have a spray can like this lying around at home), but I don’t know what kind of paper it’ll be on.
print.
Hello, DimkaM
Dim> but I don’t know what paper to print on.
For any. The main thing is that this thing calmly dissolves the toner.
Hello, DimkaM
Dim> I can try (I have a spray can like this lying around at home), but I don’t know
Dim> what paper to print on
You can use any for testing. Regular laser paper is porous, so
imprint is difficult to achieve, you can use glossy ligature from any magazine, where there is less
printed (or one text is printed), the thinner the paper, the better. You can
fax paper. I bought 90 gram paper for Lomond inkjet pens.
try it, it should work...
