EMC & IP
EMP protection: Designed military enclosures to protect the instrument in the event of an EMP pulse from a nuclear explosion and other electrical interference in the high GHz ranges.
EMC certification: some of the design issues I had to overcome were meeting the EMC specifications (300MHZ) that complied with the EMC Directive 89/336/EEC and CE certification.
IP: Designed products with a demanding IP rating to include IP67 (submerged in 1m water) and MIL-STD-810, which includes; Gunfire vibration (severe) - Sand and dust exposure - Temperature shock - Low pressure (altitude) - Humidity, fungus - salt fog for rust testing - Icing/Freezing rain - Shock and transport shock - Explosive atmosphere.
Sealing design: One of the projects I worked on required the designing of a door closing mechanism and door release button for the instrument. Ensuring environmental sealing is sufficient to withstand an IP65 rating, while maintaining a minimal closure force.
