Unlike leaded components, BTCs are difficult to rework because the solder joints are hidden. The standard covers:
The IPC-7093A standard offers several benefits to electronics manufacturers, including:

This is the core of the standard, offering state-of-the-art guidance on: Unlike leaded components, BTCs are difficult to rework
is the current industry standard for the Design and Assembly Process Implementation for Bottom Termination Components (BTCs) . Formally released in October 2020, this "Revision A" is a complete overhaul of the original 2011 standard, providing critical guidance for modern leadless packages such as QFNs, LGAs, and DFNs . Why IPC-7093A is Essential for Modern Electronics
Optimizing reflow profiles (e.g., extending the soak zone to allow flux volatile outgassing).
IPC-7093A is a revision of the original IPC-7093 standard. It outlines peer-reviewed guidelines for implementing BTCs. The standard helps engineers design printed circuit boards (PCBs) and establish reliable assembly processes. Supported Component Types However, it is critical to understand the legal
The document clearly defines QFN (Quad Flat No-lead), DFN (Dual Flat No-lead), and other BTC variants. It includes cross-sectional diagrams showing the difference between punch-type and saw-type singulation, which directly impacts side wetting expectations.
Filling vias with epoxy and plating copper over them. This is the gold standard for high-reliability BTC design.
