Brass sheetmetal etching
For modellers (model railways or model engineering), we often need to make two-sided chemical etching of brass sheets (with standard thickness of 0.3mm, 0.5mm, 1mm etc).
The process itself (including the gerber file stage, and the etching stage) is very similar to the PCB manufacturing, except:
- sheetmetal etching only has two side to etch
- no vias, electroplating or printing on top of the sheetmetal.
So I guess the sheetmetal etching process is simpler than PCB manufacturing and uses the same etching equipment as PCB manufacturing, therefore I guess it would be relatively easy for seeedstudio to do sheetmetal etching without extra capital investment, but this would be an immense help for us modellers.
