Mask-Less Selective Plating of Leadframe |
| 摘要 |
A method for selectively plating a leadframe (1100) by oxidizing selected areas (401, 402, 403, 404) of the leadframe made of a first metal (102) and then depositing a layer (901) of a second metal onto un-oxidized areas. The selective oxidations are achieved by selective active marking |

1. A method for selectively plating a leadframe comprising:
using a maskless process to selectively oxidize a plurality of selected areas of a leadframe made of a first metal leaving a plurality of un-oxized areas; and depositing a layer of a second metal onto the plurality un-oxidized areas; wherein the step of selectively oxidizing includes the step of transferring heat into the selected leadframe areas for accelerating oxidation of the first metal. |
