Actinica - Microsense project manufacturing updates
Post date: Jan 20, 2012 10:06:35 PM
Initial flange batches caused 25% of transducers to fall outside of specification.
Production problem:
Transducers failed with the plastic shield raised above edge of flange.
Magnetic core failing parallel spec of +- 0.0015"
Corrective actions to lower transducer rejection rate:
New fixture designed for curing potting compound ready for future transducer orders
Lowered initial step from 0.005" to 0.007" - preventing film protruding from bottom of flange
Breaking outside edges of flanges reduced rejection rate 10%
