A kind of method forming metal or metal alloy layer on substrate is described, the method comprises the following steps: i) provide substrate (102), this substrate (102) includes the lasting resin bed (103) at least one contact area (101) top and the interim resin bed (104) on lasting resin bed top, ii) make to include the whole substrate area of at least one contact area and be suitable for providing the solution of conducting shell (106) to contact on the surface of a substrate, and be iii) electroplated onto metal or metal alloy layer (107) on conducting shell. |
