POLYIMIDE BRIDGES AND DAMS

Another example of adding value through innovation is found while utilizing Polyimide for bridges and dams. The advantage of poly bridges over traditional air bridges is that non-conductive polyimide adds a level of support preventing the bridge from collapsing onto the circuit below.

Spectrum Microwave has taken that process one step further by adding a second layer of polyimide on top of the bridge, complementing the foundation of structural integrity added to the bridge process by the base Polyimide layer.

Polyimide, when added traditionally, allows for repeatable coupler lines and spaces.

  • Solder dams can prevent a breach of unwanted solder through to a via which could contaminate the opposing plane.
  • Adding a strip of non-conductive Polyimide near critical bonding pads prevents solder from reaching open vias.
