At the production test facilities of a major circuit fabricator, it was dance time – all the time!

This company fabricated garage door openers by the thousands, and put them through their paces on a neat row of test positions. The problem was, one tester would open his “door”, and his neighbor’s “door” would go down! A fun time, but terrible for production rates.

The problem was that the production test fixtures were hot with RF from the door opener transmitters on a common frequency, so were interacting with each other.

The frustrated quality control chief presented the problem to LBA Technology EMC engineers who were able to design a custom EMFaraCage™ faraday cage that fit the existing test fixtures. Using an internal antenna probe, testing showed complete isolation of the test positions.

After LBA provided custom EMFaraCages™ for all the test fixtures, the dance of the garage door openers came to a stop!

EMFaraCages™ have solved problems of RF interference in some of the most unlikely places from lab animal cages to nuclear enrichment facilities to cell phone testers. LBA is anxious to tackle your RF shielding or isolation problem.
