Abstract: A method for inhibiting growth of tin whiskers is provided. The method includes providing a metal substrate, forming a tin layer to cover the surface of the metal substrate, and treating the metal substrate covered the tin layer by an annealing process, wherein the annealing process is performed at 400° C.-600° C. and the surface of the tin layer is subsequently inhibited from growing tin whiskers.

Abstract: A method of bonding a solder ball and a base plate and a method of manufacturing a packaging structure using the same are provided. The method of bonding a solder ball and a base plate includes the following steps. First, a base plate including an electrode layer and a base material layer is provided. The electrode layer is disposed on the base material layer. Next, a barrier layer is formed on the electrode layer. Then, a metal layer is formed on the barrier layer. The thickness of the metal layer is about 10˜18 micrometers. Further, a solder ball is disposed on the metal layer. Afterwards, the solder ball, the metal layer, the barrier layer and the electrode layer are heated to a reacting temperature and kept for a holding time.
