Let me give you the direct facts:
: 12-bit minimum (16-bit recommended) with simultaneous sampling across all channels. Measurement Metrics
: A minimum of 500 Hz (though 2 kHz is recommended) to capture rapid dynamic events like board snaps or fixture engagement. Resolution
The standard helps engineers identify high-stress steps in the production cycle. By measuring surface strain, manufacturing facilities can minimize the risk of solder joint cracking, pad cratering, and component damage. Why Strain Gage Testing Matters
