An integrated circuit anti-bridging leads design
摘要:
An IC package design and method of making the package design that provides anti-bridging between metal leads. The anti-bridge IC package design extends bottom covercoat material out onto the leads a sufficient distance to prevent solder bridging that typically takes place in cup regions of gull wing shaped leads. A further feature of the invention is to provide a method of applying covercoat material to the IC and the leads in the same process step. A resilient material wheel and related manufacturing equipment is used to apply a single covercoat material, like epoxy, in a single step that serves as both the bottom covercoat and lead anti-bridge coat for the IC.
