Bump-on-Trace Methods and Structures in Packaging |
摘要 |
A method and structure for bump-on-trace bonding is provided. In an embodiment traces to be used for bump-on-trace (BOT) bonding are protected during a pre-solder treatment. The pre-solder treatment improves the adhesion between the exposed traces (e.g., the non-BOT traces) and a solder resist layer. |
