Section 6.4.2 provides a thermal profile graph. To reduce voids, increase the preheat soak time (90-120 seconds) to outgas flux volatiles before the solder melts.

Section 6 recommends using a "windowpane" pattern on the thermal pad instead of a solid solder paste layer. This allows gas to escape. ipc-7095 pdf

, titled "Design and Assembly Process Implementation for BGAs (Ball Grid Arrays)," is the definitive industry specification for the entire lifecycle of BGA components. If you are searching for the ipc-7095 pdf , you are likely an engineer, quality manager, or technician looking for the official documentation to solve real-world problems involving voiding, reliability, or manufacturing defects. This allows gas to escape

Introduction: What is IPC-7095? In the world of high-density printed circuit board (PCB) assembly, few components are as ubiquitous—or as challenging—as the Ball Grid Array (BGA) and Chip Scale Package (CSP). As electronic devices shrink while performance demands explode, the need for a robust, industry-wide standard for handling these components has never been greater.

Open Section 8 (Inspection). Table 8-1 shows the voiding acceptability chart. For a "Class 2" product (general industrial), a 40% void fails.
