Given these challenges, a systematic design and assembly methodology is essential for ensuring high yields and reliable product performance.
Common package types covered extensively under the IPC-7093A guideline include QFN, DFN, SON, LGA, and MLP. Core Focus Areas of IPC-7093A
IPC-7093A provides ideal TAL windows to ensure complete wetting without causing excessive intermetallic compound (IMC) growth, which embrittles the joint. ipc-7093a pdf
IPC-7093A is written for practitioners—engineers and managers responsible for design, assembly, inspection, and repair processes.
As electronic devices shrink, BTCs have become ubiquitous due to their small footprint and excellent thermal performance. However, because they lack leads, they are less forgiving during the assembly process. Following IPC-7093A helps manufacturers: Increase production yields. Reduce the need for expensive rework.

In an era of relentless device miniaturization, surging power requirements, and the unyielding demand for greater functionality, the electronics industry faces a formidable challenge: how to pack more performance into less space. At the heart of this challenge lies a class of components that has revolutionized modern electronics—. From the ubiquitous QFN (Quad Flat No-Lead) packages in your smartphone to the LGA (Land Grid Array) chips in high-performance computing, BTCs are everywhere. However, their implementation is fraught with complexities that can derail product reliability and manufacturing yields. This is where the IPC-7093A standard becomes indispensable. This comprehensive guide explores the IPC-7093A PDF, providing everything you need to know about this essential resource for designing and assembling reliable BTCs.
BTCs have gained immense popularity due to their excellent electrical performance, small size, and superior thermal properties. However, their construction, where terminations are hidden under the component body, introduces unique challenges for design, assembly, and inspection. For example, one significant risk is the potential for dendritic growth, which can cause short circuits if flux residues remain trapped between the component and the board after soldering.

Released in October 2020 (with a subsequent 2026 update noted), is the updated, comprehensive guide for handling BTCs. It replaces the original 2011 standard and provides updated, practical guidance for the entire lifecycle of bottom-only termination components. The standard focuses on: Design: Land pattern design and thermal pad requirements.
The IPC-7093A (now superseded by Revision B) standard is an essential tool for any organization working with modern, high-density surface-mount technology. It addresses the critical design, assembly, and reliability challenges of Bottom Termination Components, providing practical, industry-vetted solutions.
IPC-7093A outlines how to calculate the correct size for perimeter pads and the central thermal pad.
