A Passive Enabled Flex Tape Folded Package

Disclosed is a method that creates a fold pivot point by mounting a non-conductive cylindrical object (passive component) to a flex tape near the fold region. The disclosed method enables an accurate and repeatable fold.

Background

To date, there is no good, repeatable folding operation to create folded flex packages. Currently a folding jig is used to fold the base of the FSBGA package.�

General Description

The disclosed method solders the passive near the fold region, then folds around the passive (see Figures 1 through 3). By using a pick and place, the passive is placed at the bottom portion of the folded package. The folding technique is identical to the current state of the art, but with the passive there is a “hard stop” for the fold. Using tolerance techniques guarantee repeatable passive diameters and package spaces.

Advantages

The disclosed method enables an accurate and repeatable fold.
