Mesmerizing PCB rubout‼️ Rub-Out algorithm = used to free defined areas of the PCB, or even the whole board, from remains of copper. This is especially important for HF applications, or just to avoid shortcuts around critical connectors. You can rub-out any area of your #PCB with this algorith via Faye H #automation
Thanks Florian for sharing, indeed it looks awesome. However I used a machine like this I think it was from LPKF. I highly discourage anyone buying one. The PCB bed was warping all the time. A lot of maintenance was required and a lot of post processing is also required with the PCB such as installing vias manually. You never get a return on your investment.

Developing a testing pcb can be a pain, and is not the HF interferences design first the pcb on cad, later send it to a workshop for photo printing and acid treatment to remove copper. It take weeks to do. With this method, the prototyping is on the fly.

Removing this extra copper can have many consequences. The copper only needs to be removed or left for circuit design, such as: Distracting from, or adding to, the Intrinsic Capacitance, Induction, or Radiation as a "circuit component". This needs to be indicated on the schematic, in all cases, where it might/can matter to the circuit performance. Removing this copper can and will help /prevent the PC board from resisting bending, settling, and mechanical vibration. (Which can modulate the circuit's values. Note: This modulation circuit component can be a circuit function feature!) This extra material can also be used to: mate/interface with, testing/repair, or for charging functions. For example, if for a high current circuit connection or a low ohm value resistor. In a few words, all copper is part of the circuit design. Also known as Second-Order and Parasitic effects. PS: for dealing with stray material causing trace-to-trace conduction, use a (conformal) coating Buck_crowley@msn.com
I loved the precision of the overall process..
I could watch this for days
Remembered doing this on the college days and really struggling on the usual manual method. Well good thing my Dad suggest to have it via silk screened with the use of photographic silkscreen. And no sweat it was very accurate to the wire. 😉

1wI use our 3d MSLA printer with 20um pixel size (anycubic photon mono 4k) to expose pre-sensitized copper clad boards. I use a free SW called UV tools to export 1 layer slice file.After exposing the pcb i just dip it in developer for a minute, followed by rinsing and 30 minutes of etching in a Tupperware tub filled with water solution of Sodium persulfate. 6mil trace space is easy. 45 minutes from start to end. Cheap, fast and efficient.
