Abstract Scope |
Planar transformers manufactured by direct write additive manufacturing on magnetic substrates are smaller, lighter weight, and more robust compared with traditional wire wound transformers. Aerosol jet printing (AJP) is a direct write AM process which can print features of 10s of µm in linewidth, but the nanoparticle inks have lower conductivity compared with bulk metal. When paired with electrodeposition of Cu and Ni onto AJP seed layers, high conductivity features can be manufactured while maintaining the resolution of AJP. Processes for AJP and ultrasonic spray of dielectric polymers were also developed as separation layers between inductors. These processes were evaluated for reproducibility, uniformity, conformal coating, and speed of processing. Finally, the electrical properties of the inductors and transformers were modeled in COMSOL and compared with experimental measurements of devices manufactured with this hybrid method. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. SAND2024-04775A |
