The ASC Edge:
Automated SMD Construction on the Flex Lines
Ademco has been a pioneer in the use of Surface Mount Device (SMD) construction in the
security industry. Starting with surface mount passive components like resistors and
capacitors, then moving to integrated circuits like amplifiers, now even sophisticated
microprocessors are surface mounted on Ademco's Flexible Manufacturing Lines. All Ademco
motion detectors, fabricated using automated SMD construction, provide you and your
customers with major benefits:
1. Higher Reliability: Each component is located precisely by robotic
cameras and each solder connection is carefully controlled by computer.
2. Fewer "out-of-the-box" problems: Because the components are
automatically selected and placed properly on the PCB, there is virtually no opportunity
for error in the fabrication process.
3. Improved RF Immunity: SMD components have no leads that could act as
miniature antennas where absorbing even a minute amount of RF energy can lead to false
alarms in high gain circuits such as PIR motion detectors.
