I have no luck on toner transfer.
I found there is a laser engraver/cutting shop in my area.
Unfortunately, they only accept acrilyc and other soft material .. not for PCB board.
I make a work oround steps for this.
I spray the coper layer of my blank PCB with a paint.
I did a cam job for my board with "ps-inverted" as device, and here is the result picture
1.A cam job for bottom
1.B Open the result in Gimp
With that ps file , I bring my painted blank PCB to the shop.
The laser engraver (trotec 100 speedy) scratch out unwanted paint as expected.
Etch my board so engraved pcb ... an voila I got realy good bottom trace, including where the drills supposed to be.
Now I want back to the shop to ask them to "cut" the drills, remember that the is already no copper layer at the drill locations ... just plain FR4, So I'm sure their laser gear will do the job.
For this, I need to have a PS file with drills in it.
Here is my step
2.A cam job for drill
the problem is that this cam job didn't "print" the black dots for drill ... but it print the "icon" of the drills.
Here is when I open it in GIMP
2.B Drill PS in GIMP
My Question :
How to produce something like picture in 1B, but just the black dots/circle of drills ?
Note : The operator at the shop only work with CorelDraw, so they only accept vectors such as ps, svg, cdr
