Bottom termination component (BTC) use has increased substantially over the past decade, with today’s assemblies often encompassing various types of BTCs within one assembly. Flanagan’s presentation, Avoiding the Pitfalls of Voiding in PCB Assemblies, tells us how the industry has explored process modifications to assist with achieving the lowest voiding in large ground plane solder joints through optimizing pad design, pad patterning, stencil design, via positioning, solid solder addition, and reflow profiles. This presentation discusses how IPC’s recommendations for design and implementation of BTCs and impending changes to IPC-7093 can help minimize voiding and ensure robust BTC assemblies.
