I'm trying to produce solder paste stencils internally to avoid the cost and delays of outsourcing them, and this seems like a natural fit for my CNC mill, but I'm really not sure what kind of aluminum I should be looking for. I meausred a stencil I have beside me and it is 0.15mm thick, but I'm not sure what type of aluminum it is ... or where in the world I can buy it online. If anyone has any suggestions on what type of material to use and a potential source, it would be greatly appreciated.
