*2.1.7 Galvanic metallizer for PCBs*

This machine adds a layer of copper to the PCB, being necessary to metallize holes and cuts in the prototype. The layer of metal can be estimated mathematically depending on temperature, time, and current, or it could be measured if necessary. Maximum dimensions for substrates are around 200 290 mm/230 mm 330 mm for the typical models. In **Figure 7**, an example of these machines can be seen.
