One of the key areas covered in this standard is technology (also known as Intrusive Reflow). This technique allows through-hole components to be soldered during the reflow process, eliminating the need for wave soldering. The IPC-9704 PDF outlines the design rules, stencil requirements, and process parameters to make PIP successful.

Pinpoint specific manufacturing steps (e.g., ICT, functional testing, manual handling) that exceed safe strain limits.
The 32-page standard is structured to guide engineers through the entire testing process: 1. Strain Gage Selection and Placement
Are you dealing with specific BGA failure types (e.g., corner failures or center failures)? ipc-9704 pdf
Modern electronics feature smaller solder balls, lead-free alloys, and thinner boards. These factors make assemblies brittle and prone to structural failure under physical stress. Critical Risk Factors
If you provide details about the specific BGA package or assembly process you are testing, I can offer more tailored advice on strain gauge placement. Go to product viewer dialog for this item. JEDEC JS 9704 PDF - Engineering Standards Download

Engineers often look for the IPC-9704 PDF alongside IPC/JEDEC-9702. While related, they serve different functions: IPC/JEDEC-9702 Production and assembly testing guidelines. Board-level interconnect characterization. Application Measuring assembly line process stress. Testing specific component reliability under load. Goal Optimizing factory fixtures and methods. Defining maximum allowable strain limits for components. Implementing IPC-9704 in Your Workflow

Don't gamble with cracked capacitors. Get the standard, run the test, and sleep well knowing your solder joints will survive the real world.
The IPC-9704 standard has become integral to quality assurance across multiple sectors: Now, let's address the elephant in the room:
IPC/JEDEC-9704A provides industry-standard guidelines for measuring mechanical strain on Printed Circuit Assemblies to prevent solder joint damage during manufacturing processes like testing and depanelization. It mandates specific techniques, such as using three-element rosette strain gages and high-frequency data acquisition, to ensure, in particular, the structural integrity of BGA components.
