I have an E322822 circuit board with the markings of A.F.054.5/04 08_03. Wat do those markings mean? How do I get the Gerber file for this board?

  • \$\begingroup\$ Those markings may be PCB manufacturer- or designer- or even product manufacturer-related. I'm not sure if the PCB manufacturer or the product designer would be happy to share the gerber files with random people unless they are free for everyone. \$\endgroup\$ Commented Jun 10, 2022 at 9:12

  1. It appears to be an industrial control board made by Siemens, which may include a Modbus interface.
  2. You'd have to ask Siemens what the markings mean, or find a circuit diagram or device guide that explains it. Good luck.
  3. Ask Siemens. They are unlikely to provide you with Gerber files though (unless you can cart up enough wheelbarrows full of cash to make it worth their while.) Failing enough wheelbarrows full of cash, you could recreate the layout using any of the freely available PCB design packages.

Now that you've added photos, it is clear that it is not the Siemens board I linked to.

The one you have is relatively simple. If you were an experienced user of an electronics design package, you could draw up a copy and generate the needed Gerber file(s) easily.

  • \$\begingroup\$ The link I posted is for someone selling those boards. It might be faster and easier to locate a used baord than to try to copy it. \$\endgroup\$

The markings are not very relevant. This is a 4-layer board and you'll have to reverse-engineer it, i.e. figure out the connections, and re-draw it using KiCad (realistically). The board looks to be designed to deal with mains voltages, so it requires attention to clearance and creepage distances. Unless you have the time and willingness to learn all about it in a short time, you might be best served getting a consultant engineer to copy the board for you. Should take a day's worth of work at most.

The board has been damaged due to improper procedure when desoldering the components. There's plenty of delamination both within the board and between the board and the pads.
