Why would you be concerned about customers knowing what ICs you are using?
Will they roll their own and stop using yours? Not likely unless it's
something they use a lot of and they could justify the NRE of making a
clone. Why would they examine the unit so closely, unless it stopped working
and they wanted to repair it?
My previous version Ortmaster product used a Maxim MAX167 12 bit A/D
converter, and the distributor for the product, who bundled it with his
software, was afraid that his customers would make their own instrument if
they had the schematics and/or the part number of the IC, so I usually
sanded off the markings. He was also worried that people would copy his
software so he used a parallel port dongle. He encrypted the data files for
time/current curves which were supposedly proprietary and kept secret by a
large company (Cooper), who had taken the data from their tests of their
reclosers and published the curves on paper, but used the original data
points in their V-Pro software.
He was most worried about one large customer, Solomon, and he said they were
working on software and hardware that would replace my Ortmaster and his TCC
program. By around 2002 it was becoming a problem for customers to use
legacy computers with MSDOS and parallel ports, and the software and
hardware would not run on any version of Windows except Win95 (and maybe
Win98) in true MSDOS mode. So he had me design a version of the Ortmaster
that would work on a serial port (and then a USB port), while he developed
new software for his curve verification application. I had my device working
within 6 months, but he offloaded the software on a part-time student who
insisted on using DotNet because that's what he was studying, and then the
guy quit, and he got another developer to work on it.
But there was never any software spec and things never seemed to work right.
Customers were calling and emailing me and asking when the new version would
be ready, and all I could say is that Roy was working on his part, but they
called him and he never returned calls. I got calls from Solomon and they
were working on their own version because they could not get any
satisfaction from Roy. After 5 or 6 years of this, I developed my own
comprehensive software package and I've been selling it directly to
customers since 2009. And my biggest customer was Solomon. Roy still has had
the same website at
www.rfei.net since ten years ago, that gives the status
of the product he may still be trying to make.
