A structured reporting format is specified to ensure data consistency across organizations and test campaigns. The required format includes:
The provides a detailed methodology for strain gauge placement and PCBA strain testing, specifically addressing printed board warpage issues throughout the manufacturing process.
It identifies problematic assembly and test processes and provides systematic steps for implementing PCB strain gage tests. ipc-9704 pdf
Strain measurements can vary significantly between identical processes due to operator technique, equipment variation, or environmental factors. Statistical approaches and appropriate sample sizes are recommended.
The standard is essential for any organization involved in PCB assembly, as excessive strain can result in various failure modes for different solder alloys, package types, surface finishes, and laminate materials. By implementing the methodologies outlined in IPC-9704, manufacturers can identify hazardous processes, quantify board flexure, and take corrective actions before failures occur. A structured reporting format is specified to ensure
Printed Circuit Assembly Strain Gage Test Guideline
Finding the is often the first step for engineers looking to establish a robust testing protocol. Here is why this document is indispensable: manufacturers can identify hazardous processes
across the entire manufacturing process, including SMT assembly, testing, system integration, and all operations that may induce board flexure
IPC‑9704 has undergone major revisions since its first release. Understanding the revision history is essential for anyone seeking the correct version.
