Card Warpage Ramp

This fixture is a gravity-fed ramp with defined gaps for the quick in-production Pass/Fail testing of overall card warpage. The ramp gap is calibrated to quickly identify un-embossed cards with an overall warpage exceeding 1.5mm. A secondary gap identifies cards with warpage exceeding 1.3mm.
Crafted from aircraft grade 6061 aluminum/steel alloy bar stock and electrostatically coated for a durable long-lasting finish. Fitting and test weight are made of stainless steel.

 How to use:  Insert a un-embossed card from top gap, and see if the card can pass the two gaps by gravity.   Calibration  In case calibration is needed, use a feeler gauge to check the gap to see if the top gap is 1.5mm,  and secondary gap is 1.3mm.
