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%
