RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Itron Smart Meter Production RF Cafe Videos for Engineers
friend who has been an RF design engineer working in the smart meter industry since its inception sent me this
video of Itron's (a competitor of his) smart meter production facility in Oconee, South Carolina. My first
response upon viewing the video was gratitude to Itron for actually locating the plant in the U.S.! Then, I
settled in to enjoy the high quality of the video production by the crew from How It's Made*.
have never been in an electronics assembly environment, you cannot fully appreciate the capability of these
automated machines. Bare printed circuit boards have solder paste silkscreened onto them via an automated process
that guarantees repeatability, and then are moved to the assembly area. BTW, equally amazing is the process used
to manufacture the PCB itself (at another factory). The speed and accuracy of the pick-and-place machines is
mesmerizing; I find myself staring in awe while watching the head pick up the component from the feed tape
(sometimes after visually verifying the component by its markings), position itself over the PCB, rotate for
proper orientation, deftly place the component into the screened-on solder paste footprint pattern, then zip over
to pick up the next part and repeat the process over and over. Fully populated boards are then moved into an oven
where carefully engineered temperature ramping assures a perfect solder joint that accommodates component package
requirements and avoids detrimental effects of air pockets in the solder and mechanical stress in components. A
combination of manual and automated inspection and test processes help ensure that every meter that leaves the
factory is in perfect working order, and will function properly for its designed lifetime under often times
severely harsh environmental conditions.
Top political figures in the U.S. have recently publically
lamented the lack of jobs that automation has supposedly created. ATMs are evil in their estimation because they
put bank tellers out of work, to name an example (I wish it was a joke). The truth is that even with a high level
of automation, there are a lot of jobs created for engineers, managers, production line and shipping workers,
plant maintenance staff, and personnel for many other tasks. There are not enough
willing and able manual laborers in the world to produce the
volume of products needed to satisfy demand. Anti-science and anti-progress thinking like the aforementioned would
have us stuck in the third world.

Itron Smart Meter Production Video
Smart Meters are at the center of a lot of controversy, mainly for their adverse health effect and privacy
invasion potential. The guy who sent me this video link also sent a link to a humorous video that lampooned the
notion that smart meters are responsible for either of those two conditions, but in the couple days since he sent
it, YouTube has taken down the video due to copyright issues. I can't find is anywhere now. It's a conspiracy!
An excellent overview from the
Fraunhofer Center for Sustainable Energy Systems titled, "Nonintrusive
Appliance Load Monitoring: Review and Outlook" is available on the IEEE Xplore website, but you need to either
have a subscription or pay for it separately. The fact is that while first-generation smart meters may only report
consumption data, their planned evolution includes an ability to transmit detailed, time-stamped information that
includes separate values for current, voltage, and power factor. That allows use of statistical models for
extracting likely usages of appliances, computers, lighting, heating and air conditioning, etc. If you think that
is a stretch, just think of how those same three metrics are used routinely now in radar to assess target
identity, capability, and intention.
Now, for a little levity, check out this video where CBS Channel 5
News reports on smart meters catching on fire. Of course, they found a toothless guy to interview about the
dangers of the meters.

Here's utility company smart meter installer being chased off someone's property. As you can imagine, there
are scores of similar videos available.
