Abstract:
As the frequency of RF packages climb up and beyond 60 GHz, microstrip and waveguide line widths diminish with substrate thickness and the limitations of traditional interconnect bonding techniques reach their limitations.  Printed 3D Interconnects made with Aerosol Jet® printing provide package designers and RF engineers a new tool to tailor the impedance of transition interconnects, designing the loss characteristics to the application need and eliminating the need to compensate for poor signal through loss and back reflection behavior driven by impedance mismatch.  Printed 3D interconnects made with Aerosol Jet can be digitally designed to be any shape or thickness and with line widths as thin as 10 microns and thinner than 1 micron it is capable of handling RF interconnect needs well above 100GHz.  All of this enables the interconnect itself to be designed into the package, similar to the microstrip or die circuit design it will be interconnecting. Finally, the interconnects are conformal to the surface of the package, minimizing trace length and eliminating air gaps between the interconnect and the substrates ground plane lowering transition loss by up to 50%.  Examples demonstrating this up to 110 GHz will be shared along with the process and equipment used to perform it.

Presenter Bio:
Bryan Germann is product manager of the Aerosol Jet Product line, including machine platforms, print engine products, and digital products.  He is also managing strategic customer projects centered around volume production applications for Aerosol Jet technology. Bryan joined Optomec in mid-2017, previously he worked for GE Power he successfully integrated Optomec’s Aerosol Jet technology into production work cells for printing high temperature ceramic sensors on heavy-duty gas turbine blades.  His background in materials, process and Optomec’s core technology enables him to Optomec’s customer base working on high volume, production applications for Aerosol Jet.  Bryan currently holds 13 published patents. He also holds a B.S. and M.S. in Mechanical Engineering from University of South Carolina(USC).
