IPC Releases IPC-7093A, Design and Assembly Process Implementation for BTCs
February 15, 2021 | IPCEstimated reading time: Less than a minute
The long-awaited release of IPC-7093A, Design and Assembly Process Implementation for Bottom Termination Components (BTCs) is here. Revision A is a complete overhaul of IPC-7093 which provides design and assembly guidance for implementing BTCs and focuses on critical design, materials, assembly, inspection, repair, quality, and reliability issues.
IPC-7093A includes a step-by-step process on how to design and incorporate BTCs into any card layout. Comprehensive descriptions on how to successfully implement robust designs and assembly processes and troubleshooting guidance for common anomalies which can occur during BTC assembly are included.
Revision A adds state-of-the-art guidance on critical elements for thermal pad design, thermal via usage, stencil design, assembly recommendations, reliability considerations, known issues/ defects to avoid. The standard’s multiple design point options enable reliable BTC designs.
The standard is ideal for anyone involved with physical design, process and reliability engineers or managers who are responsible for design, assembly, inspection, and repair processes.
“BTCs are in integral part of electronic designs today,” stated Matt Kelly, IPC chief technologist. “With increased product functionality, device miniaturization, and increased power consumption the need for optimized thermal management has never been higher.”

Elementary Mr. Watson: Chasing Checkmarks, Not Signal Integrity
10/01/2025 | John Watson -- Column: Elementary, Mr. WatsonFor the September 2025 issue of Design007 Magazine on signal integrity, I explored how the PCB is similar to a military obstacle course: walls that sap energy like impedance mismatches, barbed wire that cuts like crosstalk, and mud pits that drag a signal down like attenuation. The takeaway was clear that a PCB is not a flat drawing; it's an electromagnetic ecosystem filled with hazards that test every signal that dares to cross it. The real danger lies not in the obstacles themselves, but in the fact that many designers never see them.
Target Condition: Rethinking the PCB Stackup Recipe
10/01/2025 | Kelly Dack -- Column: Target ConditionMarie Antoinette is attributed with saying, “Let them eat cake,” but historians now agree she likely never said it. It was probably revolutionary propaganda to paint her as out of touch with the starving masses. Yet, the phrase still lingers, and oddly enough, it applies to the world of PCB design.
Connect the Dots: Evolution of PCB Manufacturing—Lamination
10/02/2025 | Matt Stevenson -- Column: Connect the DotsWhen I wrote The Printed Circuit Designer's Guide to...™ Designing for Reality, it was not a one-and-done effort. Technology is advancing rapidly. Designing for the reality of PCB manufacturing will continue to evolve. That’s why I encourage designers to stay on top of the tools and processes used during production, to ensure their designs capitalize on the capabilities of their manufacturing partner.
