Just add another line directly after:
Range(Cells(Target.Row, "A"), Cells(Target.Row, "AA")).Copy Sheets("Order Board").Cells(Rows.Count, "A").End(xlUp).Offset(1, 0)
say (adjusted for your sheet name):
Range("A" & Target.Row & ":AA" & Target.Row).Copy Sheets("AnotherSheetSomewhere").Cells(Rows.Count, "A").End(xlUp).Offset(1, 0)
or replace that original line that copies with:
With Range(Cells(Target.Row, "A"), Cells(Target.Row, "AA"))
.Copy Sheets("Order Board").Cells(Rows.Count, "A").End(xlUp).Offset(1, 0)
.Copy Sheets("AnotherSheetSomewhere").Cells(Rows.Count, "A").End(xlUp).Offset(1, 0)
End With
