Additive manufacturing (AM) techniques are increasingly being employed in electronics packaging. In particular, AM can be used to create planar magnetics with complex designs that can improve power module efficiency. In this presentation, we will focus on two aspects:
(1) Utilizing a paste-based AM technique, syringe-printing, to fabricate planar transformer windings on ceramic substrates using silver-based pastes. This will include a discussion of manufacturing considerations including printable trace width, gaps, and heights; the effect of the sintering process on electrical resistivity; and the adhesion at the metal/ceramic interface.
(2) Conducting a series of accelerated life tests on the AM-printed silver-based windings, including temperature-humidity exposure, thermal aging, and thermal cycling, to identify and characterize the failure modes and mechanisms.
