The Ultimate Guide to IPC-7093A PDF: Design and Assembly Process Implementation for Bottom Termination Components (BTCs)

Introduction: Why the IPC-7093A Standard Matters

In the fast-paced world of electronics manufacturing, the drive toward miniaturization has forced designers and engineers to abandon traditional peripheral-leaded packages in favor of space-saving alternatives. Among these, Bottom Termination Components (BTCs) —such as QFN, DFN, and MLF packages—have become ubiquitous. However, with their hidden solder joints beneath the component body, BTCs present unique challenges for inspection, reliability, and thermal management.

• Single voids > 30% of pad area.
• Total voiding > 30% for non-critical boards.
• Voiding > 20% for automotive or medical devices.
