| Abstract Scope |
The convergence of additive manufacturing (AM) along with multiple applicable technologies has been shown to augment the functionality of printed parts such that mechanical, electrical, and electromagnetic functions can, for example, reside within the same part. This work used an electrical connector commonly used in satellites to demonstrate a hybrid AM approach by embedding the connector, ultrasonically embedding wires, and laser soldering. The connector was a six-pin Easy-on FFC/FPC connector with a fine pitch and leads of 200-micron width. Resistance measurements were carried out during laser soldering, application of insulation material, and encapsulation with thermoplastic extruded at high temperatures (> 300⁰C). The measurements were made to observe the impact of 1) a laser power profile and 2) thermal input from the extrusion nozzle and heated build environment for diagnostics of low yield or performance. Additionally, temperature history data was collected to coincide with resistance measurements. |
