Most commercial standards operate on a licensing model. The "Single User" license, costing between $190 and $240, allows one individual to access the PDF on a limited number of devices. For organizations with multiple engineers, "Corporate" or "Global" licenses are available, allowing for company-wide access. Prices vary for members versus non-members of the IPC.
IPC-7095 is a standard developed by the IPC (Association Connecting Electronics Industries) that specifically addresses the challenges associated with BGA inspection, design, assembly, and reliability.
Voiding is one of the most common issues in BGA assembly. IPC-7095 provides clear criteria for acceptable void percentages, distinguishing between surface-level voids and hidden voids within the solder ball. ipc-7095 pdf
The IPC-7095 standard is a proprietary document protected by copyright laws.
NSMD pads offer better mechanical fatigue life because the solder grips the sides of the copper trace. SMD pads provide better positional accuracy and prevent pad lifting. IPC-7095 helps designers choose the right pad type based on the application. Most commercial standards operate on a licensing model
: Broadened scope for manufacturers transitioning heavily into full lead-free (RoHS) materials.
As technology evolves and packages become even more compact and dense, IPC-7095 and similar standards play a vital role in facilitating the adoption of new technologies by providing a framework for their integration into existing manufacturing processes.

For the most updated information on BGA design and assembly, it is highly recommended to obtain the standard from Soldertraining.com.
Proper PCB design is the first defense against BGA assembly failures. :
