Surface treatment flow diagram:
This kind of surface treatment machine uses electrolytic copper foil produced by the foiling machine as the main material.
Treatment technology: unwind - acid pickle - coarsen1 - solidify1 - coarsen2 - solidify2 - galvanize - wash by water - chroming - wash by water1 - wash by water2 - silane - dry - roll up
This kind of surface treatment machine can produce electrolytic copper foil which can meet the IPC-4562 requirement. (The number of process tanks can be specified by the customers.)
